Description

REPAIR ASSEMBLY FORA DAMAGED ELASTOMERIC ENDLESS TRACKTECHNICAL FIELD

[0001] The present application generally relates to repair assemblies, specifically repair assemblies for damaged elastomeric endless tracks.BACKGROUND

[0002] Track assemblies with elastomeric endless tracks are used by various vehicles such as military vehicles and / or industrial vehicles for a variety of reasons, notably to have enhanced traction on various ground surfaces that are soft, slippery and / or uneven (e.g., soil, mud, sand, ice, snow, etc.).

[0003] These elastomeric endless tracks can be damaged (e.g., tear) due to wear, due to harsh environment and / or due to encounters with various objects.

[0004] Replacing a damaged elastomeric endless track of a vehicle with a new elastomeric endless track, directly in the field, is not always possible. For example, the vehicle may be in a hostile environment (e.g., harsh weather, dangerous area). In another example, the vehicle may be in a location that is difficult to access, such that dispatching tools and / or equipment required to replace the damaged endless track may not be possible.

[0005] Conventional repair assemblies exist, but these can be difficult to connect to the damaged elastomeric endless track. Additionally, these repair assemblies may take too much space at least in the lateral direction, making them unusable with some vehicles that have limited clearance around the damaged endless track.

[0006] Thus, there is a need for a repair assembly that can be used to repair elastomeric endless tracks and overcome the above-mentioned issues.SUMMARY

[0085] The present disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of "including", "comprising", or "having", "containing', "involving' and variations thereof herein, is meant to encompass the items listed thereafter as well as, optionally, additional items. In the following description, the same numerical references refer to similar elements.

[0086] The present technology relates to repair assemblies that can be used to repair damaged elastomeric endless tracks. The repair assembly is configured to be easily manufactured for a number of different elastomeric endless tracks, and occupy minimal lateral space when connected to the damaged elastomeric endless track such that the repair assembly can be used when there is little lateral clearance around the endless track.

[0087] The present technology will be described with reference to a military vehicle 20, which is illustrated in Figure 1. It is understood, however, that the present technology could be used with vehicles other than military vehicles. For example, the present technology could be used with agriculture vehicles such as tractors, with industrial vehicles such as bulldozers, skid-steer loaders, excavators and compact track loaders, and / or with all-terrain vehicles such as, side-by-side vehicles or utility-terrain vehicles. It is also contemplated that the present technology could be used with trailers or other unpowered vehicles.

[0088] In the illustrated embodiment, the military vehicle 20 is an armored personnel carrier 20, the forward direction of which is indicated by arrow 21. The military vehicle 20 has a frame 22. The frame 22 supports a motor (not shown) of the military vehicle 20, and includes left and right skirts 24 (only right skirt shown in Figure 1) that extend generally vertically downward. It is contemplated that in some embodiments, the skirts 24 may be omitted.

[0089] The military vehicle 20 also includes left and right track systems 30 that are operatively connected to, respectively, left and right sides of the frame 22. More specifically, the right track system 30 is disposed, with respect to the military vehicle 20, laterally inwardly from the right skirt 24. Likewise, the left track system 30 is disposed, with respect to the military vehicle 20, laterally inwardly from the left skirt (not shown in Figure 1). The left and right skirts 24 extend downwardly beyond respective upper ends of the left and right track systems 30.

[0090] Each of the track systems 30 has a drive wheel assembly 32, an idler wheel assembly 34, road wheel assemblies 36 and an endless track 50 surrounding the drive, idler and road wheel assemblies 32, 34, 36.

[0091] The drive wheel assembly 32 is mounted at a front end of the frame 22, and is operatively connected to the motor. The drive wheel assembly 32 is configured to engage the endless track 50 to transmit motive power from the motor to the endless track 50. The drive wheel assembly 32 has a drive wheel 33 having a plurality of laterally extending teeth 40 (best seen in Figure 3). The teeth 40 extend on either lateral side of the drive wheel 33. The drive wheel 33 also defines a plurality of recesses 42 (also best seen in Figure 3). Each recess 42 is in part defined by two adjacent teeth 40. As will be described below, the recesses 42 are configured to receive inner and outer driving lugs 62, 64 of the endless track 50 therein.

[0092] The idler wheel assembly 34 is mounted at a rear end of the frame 22. The idler wheel assembly 34 is configured to adjust tension and / or to guide the endless track 50. In some embodiments, the idler wheel assembly 34 may be connected to a tensioner (not shown).

[0093] The road wheel assemblies 36 are mounted along a length of the frame 22, between the drive and idler wheel assemblies 32, 34. In the present embodiment, there are five road wheel assemblies 36, but it is contemplated that a number of road wheel may vary. The road wheel assemblies 36 are generally configured to guide a lower run portion of the endless track 50.

[0094] It is contemplated that in some embodiments, the drive wheel assembly 32 may be mounted at the rear end of the military vehicle 20 and the idler wheel assembly 34 may be mounted at the front end of the military vehicle 20. It is contemplated that location(s) of one or more drive wheel assemblies and of one or more idler wheel assemblies may depend, inter alia, on a weight distribution of the military vehicle 20. It is also contemplated that location(s) and a number of one or more road wheel assemblies may also depend, inter alia, on the weight distribution of the military vehicle 20.

[0095] With reference to Figures 2A and 2B, an embodiment of the endless track 50 will now be described. The endless track 50 has a wheel-engaging surface 52, a groundengaging surface 54 that is opposite to the wheel-engaging surface 52, an inner lateral surface 56 that extends vertically between the wheel -engaging and ground-engaging surfaces 52, 54 and an outer lateral surface 58 that extends vertically between the wheelengaging and ground-engaging surfaces 52, 54. It can be said that the inner and lateral surfaces 56, 58 extend radially (with reference to the endless track 50) between the wheelengaging and ground-engaging surfaces 52, 54.

[0096] The wheel-engaging surface 52 is operatively engageable with the drive wheel assembly 32, the idler wheel assembly 34 and the road wheel assemblies 36.

[0097] The wheel-engaging surface 52 has a plurality of longitudinally spaced inner driving lugs 62 disposed proximate to the inner lateral surface 56, and a plurality of longitudinally spaced outer driving lugs 64 disposed proximate to the outer lateral surface 58. The inner and outer driving lugs 62, 64 extend inwardly (as opposed to laterally, for example) from the wheel-engaging surface 52. The inner and outer driving lugs 62, 64 are longitudinally aligned with one another. A driving lug pitch PDL can be longitudinally measured from a front end of one of the inner and outer driving lugs 62, 64 to a front endof an adjacent one of the one of the inner and outer driving lugs 62, 64. The inner driving lugs 62 in part define inner recesses 63 therebetween. Likewise, the outer driving lugs 64 in part define outer recesses 65 therebetween. A recess pitch PR can be longitudinally measured from a front end of one of the inner and outer recesses 63, 65 to a front end of an adjacent one of the inner and outer recesses 63, 65. As previously alluded to, the inner and outer driving lugs 62, 64 are configured to engage with the teeth 40 of the drive wheel assembly 30. During operation, the inner and outer driving lugs 62, 64 are received in corresponding recesses 42 of the drive wheel assembly 30, and the teeth 40 are received in the inner and outer recesses 63, 65. It is contemplated that the configuration of the driving engagement of the track system 30 may vary from one embodiment to another. For example, in some embodiments, instead of having driving lugs 62, 64, the endless track 50 could define recesses configured to receive driving teeth of the drive wheel assembly 30.

[0098] The wheel-engaging surface 52 also has a plurality of longitudinally spaced guiding lugs 66 that are disposed on a longitudinal center plane of the endless track 50. The guiding lugs 66 extend, like the inner and outer driving lugs 62, 64, inwardly from the wheel-engaging surface 52. A guiding lug pitch PGL can be measured from a front end of the guiding lug 66 to the front end of an adjacent guiding lug 66. In the embodiment of Figures 2A and 2B, the guiding lug pitch PGL is equal to the driving lug pitch PDL. Thus, each one of the guiding lugs 66 is longitudinally aligned with one of the inner driving lugs 62 and one of the outer driving lugs 64. The guiding lugs 66 are configured to engage with the drive wheel assembly 32, the idler wheel assembly 34 and the road wheel assemblies 36 for guiding the endless track 50 relative to the wheel assemblies during operation.

[0099] The ground-engaging surface 54 has a plurality of traction lugs 70 configured to engage with the ground surface. In the embodiment illustrated in Figure 2B, the traction lugs 70 extend laterally along an entirety of a width of the endless track 50. The traction lugs 70 are longitudinally spaced from one another, such that the groundengaging surface 54 defines a plurality of spacings 72, each one of the spacings 72 being partially defined by two adjacent traction lugs 70. In some embodiments, the spacings 72 may be referred to as recesses. A traction lug pitch PTL can be longitudinally measured from a front end of one of the traction lugs 70 to the front end of an adjacent one of thetraction lugs 70. Likewise, a spacing pitch Ps can be longitudinally measured from a front end of one of the spacings 72 to the front end of an adjacent one of the spacings 72. In the present embodiment, the traction lug pitch PTL is equal to the driving lug pitch PDL. Thus, each one of the traction lugs 70 is longitudinally aligned with a corresponding inner driving lug 62 and a corresponding outer driving lug 64, and each one of the spacings 72 is longitudinally aligned with a corresponding inner recess 62 and a corresponding outer recess 65.

[0100] The endless track 50 is made of a polymeric material. It is contemplated that the polymeric material could be an elastomeric material such as, for example, rubber. Thus, the endless track 50 is flexible, thereby enabling it to conform to obstacles and / or components of the track system 30 such as the drive wheel assembly 32 and the idler wheel assembly 34.

[0101] As will be described in greater detail below, the configuration of the endless track 50 may change from one embodiment to another. For example, in Figures 2C and 2D, an alternative embodiment of the endless track 50, namely endless track 50’, is shown. On a wheel-engaging surface 52’, the endless track 50’ has inner and outer driving lugs 62’, 64’ as well as guiding lugs 66’. The endless track 50’ has traction lugs 70’ that are generally shaped like chevrons, instead of being generally straight, like in the endless track 50. The endless track 50’ also defines spacings 72’ that are also generally shaped like chevrons.

[0102] In the present embodiment, the endless track 50 of the left track system 30 is a damaged elastomeric endless track. The damage can be present in the form of a partial tear or a full tear. The damage can be a result of wear or an accident. In the present embodiment, a damaged area 80 is illustrated in Figure 2A, as a partial tear.

[0103] As shown in Figure 3, the damaged endless track 50 has been repaired using a repair assembly 100 according to an embodiment of the present technology. The repair assembly 100 is mounted to the endless track 50 over the damaged area 80. In some embodiments, the repair assembly 100 can temporarily repair damaged endless track 50,which can allow the vehicle 20 to proceed to a maintenance site for a more permanent repair of the endless track 50 or ultimately, for a replacement of the endless track 50.

[0104] Referring to Figures 3 to 13, the repair assembly 100 will now be described in greater detail. The repair assembly 100 includes an inner link assembly 102, an outer link assembly 104, support members 106 and a bridging member 108.

[0105] The inner link assembly 102 is connected to the inner lateral surface 56 with a longitudinal center point of the inner link assembly 102 being generally longitudinally aligned with the damaged area 80. The outer link assembly 104 is connected to the outer lateral surface 58 with a longitudinal center of the outer link assembly 102 being generally longitudinally aligned with the damaged area 80. The support members 106 are connected to the inner and outer link assemblies 102, 104 as well as to the bridging member 108, which extends over the damaged area 80.

[0106] The inner link assembly 102 includes a front extremity link 110, primary intermediate links 112, secondary intermediate links 114 and a rear extremity link 116. In the illustrated embodiment, the inner link assembly 102 includes three primary intermediate links 112 and two secondary intermediate links 114. It is contemplated, however, that the number of primary and secondary intermediate links 112, 114 may vary from one embodiment to another. For example, in some embodiments, the inner link assembly 102 could have, in addition to the front and rear extremity links 110, 116, only a single primary intermediate link 112 (i.e., no secondary primary link). In other embodiments, the inner link assembly 102 could include, in addition to the front and rear extremity links 110, 116, a single primary intermediate link 112 and a single secondary intermediate link 114.

[0107] The front extremity link 110 has a body 120 that generally extends in the longitudinal direction. In some embodiments, the body 120 has a length that is slightly greater than half of the traction lug pitch PTL and half of the spacing pitch Ps. The body 120 has an abutting surface 122 that is configured to abut the inner lateral surface 56 of the endless track 50, and a non-abutting surface 124 that is opposite to the abutting surface 122.

[0108] A shoulder 126 extends generally orthogonally from the abutting surface 122 at a front end of the body 120. The shoulder 126 is at least partially tubular. The shoulder 126 defines a threaded aperture 128 therein. As will be described in greater detail below, the threaded aperture 128 is configured to receive part of one of the support members 106 therein.

[0109] A tongue 130, which is generally flat, also extends generally orthogonally from the abutting surface 122. The tongue 130 is longitudinally aligned with the shoulder 126, and vertically offset therefrom. Specifically, the tongue 130 is disposed vertically below the shoulder 126, so as to receive the endless track 50 therebetween. As will be described in greater detail below, the tongue 130 is configured to be received between the inner recesses 63 and is configured to abut the wheel-engaging surface 52 of the endless track 50.

[0110] The body 120 defines a connecting aperture 132 at a rear end thereof. Thus, the connecting aperture 132 is longitudinally spaced from the shoulder 126 and from the tongue 130. Specifically, a longitudinal distance between the connecting aperture 132 and the shoulder 126 and the tongue 130 corresponds to half of the traction lug pitch PTL and half of the spacing pitch Ps. The connecting aperture 132 is also vertically spaced from the shoulder 126, with the shoulder 126 being disposed vertically higher than the connecting aperture 132. As will be described below, the front extremity link 110 is configured to pivotally connect to an adjacent link of the inner link assembly 102 via the connecting aperture 132.

[0111] The body 120 defines a recess 136 on the non-abutting surface 124 at the rear end thereof. Thus, the body 120 has a varying width, with the width being larger at front thereof (i.e., proximate to the shoulder 126 and the tongue 130), and the width being smaller at the rear end thereof (i.e., proximate to the connecting aperture 132). As best seen in Figure 9, the change in the width of the body 120 results in the non-abutting surface 124 at the rear end being laterally offset from the non-abutting surface 124 at the front end.

[0112] The three primary intermediate links 112 are all the same, such that only one will be described herewith. As seen in Figure 6, the primary intermediate link 112 hasa body 140. The body 140, which extends longitudinally, is approximately two times longer than the body 120. In some embodiments, the body 140 has a length that is slightly greater than the traction lug pitch PTL and than the spacing pitch Ps. The body 140 has an abutting surface 142 and a non-abutting surface 144. The abutting surface 142 is configured to abut the non-abutting surface 124 of the front extremity link 110, and a non-abutting surface 144 of an adjacent secondary intermediate link 114.

[0113] The body 140 has, at a longitudinal center thereof, a shoulder 146 that extends generally orthogonally from the abutting surface 142. The shoulder 146, like the shoulder 126, defines a threaded aperture 148 configured to receive part of an other one of the support members 106 therein.

[0114] A tongue 150 also extends generally orthogonally from the abutting surface 142. The tongue 150 is longitudinally aligned with the shoulder 146, and vertically offset therefrom. More specifically, the tongue 150, similar to the tongue 130, is disposed vertically below the shoulder 146 so as to receive the endless track 50 therebetween, and is generally flat. As will be described in greater detail below, the tongue 150 is configured to be received between corresponding inner recesses 63 and is configured to abut the wheelengaging surface 52 of the endless track 50.

[0115] At a front end thereof, the body 140 defines a front connecting aperture 152. The front connecting aperture 152 is thus longitudinally spaced from the shoulder 146 and from the tongue 150. Specifically, a longitudinal distance between the front connecting aperture 152 and the shoulder 146 and / or the tongue 150 corresponds to half of the traction lug pitch PTL and half of the spacing pitch Ps. The front connecting aperture 152 is also vertically spaced from the shoulder 146, with the shoulder 146 being disposed vertically higher than the front connecting aperture 152. The front connecting aperture 152 is configured to align with the connecting aperture 132 of the front extremity link 110 for providing a pivotal connection therebetween.

[0116] At a rear end thereof, the body 140 defines a rear connecting aperture 154. The rear connecting aperture 154 is longitudinally spaced from the shoulder 146 and from the tongue 150 and from the front connecting aperture 152. More specifically, alongitudinal distance between the rear connecting aperture 154 and the shoulder 146 and / or the tongue 150 corresponds to half of the traction lug pitch PTL and half of the spacing pitch Ps. Thus, a longitudinal distance between the front and rear connecting apertures 152, 154 corresponds to the traction lug pitch PTL and to the spacing pitch Ps. The rear connecting aperture 154 is also vertically spaced from the shoulder 146, with the shoulder 146 being disposed vertically higher than the rear connecting aperture 154. As will be described below, the primary intermediate link 112 is configured to pivotally connect to the adjacent secondary intermediate link 114 via the rear connecting aperture 154.

[0117] The body 140 defines, on the abutting surface 142, a frontrecess 156 toward the front end thereof, and a rear recess 157 toward the rear end thereof. Thus, the body 140 has a varying width, with the width being larger at a center thereof (i.e., proximate to the shoulder 146 and the tongue 150), and the width being smaller at the front and rear ends thereof (i.e., proximate to the front and rear connecting apertures 152, 154). As best seen in Figure 9, the change in width of the body 140 results in the abutting surface 142 at the front and rear ends being laterally offset from the abutting surface 142 at the center of the body 140.

[0118] As will be described below, the bodies 120, 140 are configured to connect to one another, such that the recess 136 of the body 120 and the front recess 156 of the body 140 can assist in providing operational alignment of the bodies 120, 140 while also minimizing an overall width of the repair assembly 100. In some embodiments, it can be said that the links 110, 112, 114, 116 are, alternatingly, laterally offset from one another, with some of the links 110, 112, 114, 116 being closer to the inner lateral surface 56, and others being further to the inner lateral surface 56. In some interpretations, it could be said that the links 110, 112, 114, 116 are laterally staggered.

[0119] The three secondary intermediate links 114 are all the same, and are mostly similar to the primary intermediate links 112. Features of the secondary intermediate links 114 similar to the features of the primary intermediate links 112 have been labeled with the same reference numerals and will not be described in detail again. The secondary intermediate links 114 notably differ from the primary intermediate links 114, in that thefront and rear recesses 156, 157 are defined on the non-abutting surface 144 instead of the abutting surface 142. Thus, it can be said that the secondary intermediate links 114 are complementary to the primary intermediate links 112.

[0120] The rear extremity link 116 is similar to the front extremity link 110 (mirror image thereof). Thus, features of the rear extremity link 116 similar to the features of the front extremity link 110 have been labeled with the same reference numerals, and will not be redescribed herewith.

[0121] When the inner link assembly 102 is assembled, the front extremity link 110, the primary and secondary intermediate links 112, 114 and the rear extremity link 116 are pivotally connected to one another via rivets 160. In some embodiments, the rivets 160 may be welded to some of the links 110, 112, 114, 116. It is contemplated that in other embodiments, an other type of fastener could be used to pivotally connect the links to one another. In some embodiments, a bearing or a bushing may be provided in the connecting apertures 132, 152, 154 for enabling rotational movement between the links 110, 112, 114, 116. In other embodiments, some of the links 110, 112, 114, 116 may have a connecting shoulder 127 (shown in Figure 5B), configured to be received in a corresponding one of the connecting apertures, this could facilitate rotational connection and / or assembly between the links 110, 112, 114, 116.

[0122] In more detail, the front extremity link 110 is pivotally connected to the primary intermediate link 112 via one of the rivets 160 that extends through the connecting aperture 132 of the front extremity link 110 and through the front connecting aperture 152 of the primary intermediate link 112. The primary intermediate link 112 is further pivotally connected to the secondary intermediate link 114 via an other one of the rivets 160 that extends through the rear connecting aperture 154 of the primary intermediate link 112 and through the front connecting aperture 152 of the secondary intermediate link 114. The secondary intermediate link 112 is further pivotally connected to an other one of the secondary intermediate links 114 via one of the rivets 160 that extends through the rear connecting aperture 154 of the secondary intermediate link 112 and through the front connecting aperture 152 of the other one of the secondary intermediate link 114. Theremaining primary and secondary intermediate links 112, 114 and the rear extremity link 116 are pivotally connected to one another as described hereabove.

[0123] As mentioned above, the presence of the recesses 136, 156, 157 can assist in providing operational alignment. Shoulders 126, 146 are all aligned with one another in the lateral direction (best seen in Figure 9), while minimizing a width of the repair assembly 100 when mounted to the endless track 50.

[0124] Still referring to Figures 3 to 13, the outer link assembly 104 will now be described in greater detail. The outer link assembly 104 includes a front extremity link 210, primary intermediate links 212, secondary intermediate links 214, and a rear extremity link 216. The outer link assembly 104 has the same number of links as the inner link assembly 102. Thus, the outer link assembly 104 includes three primary intermediate links 212 and two secondary intermediate links 214. It is contemplated, like for the inner link assembly 102, that the number of primary and secondary intermediate links 212, 214 may vary from one embodiment to another.

[0125] The front extremity link 210 has a body 220 that generally extends in the longitudinal direction. In some embodiments, the body 220 has a length that is slightly greater than half of the traction lug pitch PTL and than half of the spacing pitch Ps. The body 220 has an abutting surface 222 that is configured to abut the outer lateral surface 58 of the endless track 50, and a non-abutting surface 224 that is opposite to the abutting surface 222.

[0126] The body 220 defines toward a front end thereof, on the non-abutting surface 224, a receiving recess 225. Additionally, a receiving aperture 226 is defined in the receiving recess 225. The receiving aperture 226 is a through aperture. As will be described in greater detail below, the receiving aperture 226 is configured to receive part of one of the support members 106 therethrough.

[0127] A tongue 230, which is generally flat, extends generally orthogonally from the abutting surface 222. The tongue 230 is longitudinally aligned with the receiving aperture 226, and vertically offset therefrom. More specifically, the tongue 230 is disposedvertically below the receiving aperture 226, so as to receive the endless track 50 therebetween. As will be described in greater detail below, the tongue 230 is configured to be received between the outer recesses 65 and is configured to abut the wheel-engaging surface 52 of the endless track 50.

[0128] The body 220 defines a connecting aperture 232 at a rear end thereof. Thus, the connecting aperture 232 is longitudinally spaced from the receiving aperture 226 and the tongue 230. More specifically, a longitudinal distance between the connecting aperture 232 and the receiving aperture 226 and / or the tongue 230 corresponds to half of the traction lug pitch PTL and to half of the spacing pitch Ps. The connecting aperture 232 is also vertically spaced from the receiving aperture 226, with the receiving aperture 226 being disposed vertically higher than the connecting aperture 132. As will be described below, the front extremity link 210 is configured to pivotally connect to an adjacent link of the outer link assembly 104 via the connecting aperture 232.

[0129] The body 220 defines a recess 236 on the non-abutting surface 224 at the rear end thereof. Thus, the body 220 has a varying width, with the width being larger toward the front thereof (i.e., proximate to the receiving aperture 226 and the tongue 230), and the width being smaller toward the rear end thereof (i.e., proximate to the connecting aperture 232). As best seen in Figure 12, the change in width of the body 220 results in the non-abutting surface 224 at the rear end being laterally offset from the non-abutting surface 224 at the front end.

[0130] The three primary intermediate links 212 are all the same, such that only one will be described herewith. The primary intermediate link 212 has a body 240. The body 240, which extends longitudinally, is approximately two times longer than the body 220. In some embodiments, the body 240 has a length that is slightly greater than the traction lug pitch PTL and the half of the spacing pitch Ps.

[0131] The body 240 has an abutting surface 242 and a non-abutting surface 244. The abutting surface 242 is configured to abut the non-abutting surface 224 of the front extremity link 210, and a non-abutting surface 244 of an adjacent secondary intermediate link 214.

[0132] The body 240 defines, at a longitudinal center thereof, on the non-abutting surface 244, a receiving recess 245. Additionally, a receiving aperture 246 is defined in the receiving recess 245. The receiving aperture 246 is a through aperture. Like the receiving aperture 226, the receiving aperture 246 is configured to receive part of an other one of the support members 106 therethrough.

[0133] A tongue 250 extends generally orthogonally from the abutting surface 242. The tongue 250 is longitudinally aligned with the receiving aperture 246, and vertically offset therefrom. More specifically, the tongue 250, similar to the tongue 230, is disposed vertically below the receiving aperture 246 so as to receive the endless track 50 therebetween, and is generally flat. As will be described in greater detail below, the tongue 250 is configured to be received between corresponding outer recesses 66 and is configured to abut the wheel-engaging surface 52 of the endless track 50.

[0134] At a front end thereof, the body 240 defines a front connecting aperture 252. The front connecting aperture 252 is thus longitudinally spaced from the receiving aperture 246 and from the tongue 250. More specifically, a longitudinal distance between the front connecting aperture 252 and the receiving aperture 246 and / or the tongue 250 corresponds to half of the traction lug pitch PTL and to half of the spacing pitch Ps. The front connecting aperture 252 is also vertically spaced from the receiving aperture 246, with the receiving aperture 246 being disposed vertically higher than the front connecting aperture 252. The front connecting aperture 252 is configured to align with the connecting aperture 232 of the front extremity link 210 for providing a pivotal connection therebetween.

[0135] At a rear end thereof, the body 240 defines a rear connecting aperture 254. The rear connecting aperture 254 is thus longitudinally spaced from the receiving aperture 246 and the tongue 250 and from the front connecting aperture 252. More specifically, a longitudinal distance between the rear connecting aperture 254 and the shoulder 246 and / or the tongue 250 corresponds to half of the traction lug pitch PTL and half of the spacing pitch Ps. Thus, a longitudinal distance between the front and rear connecting apertures 252, 254 corresponds to the traction lug pitch PTL and to the spacing pitch Ps. The rear connecting aperture 254 is also vertically spaced from the receiving aperture 246, with the receivingaperture 246 being disposed vertically higher than the rear connecting aperture 254. As will be described below, the primary intermediate link 212 is configured to pivotally connect to the adjacent secondary intermediate link 214 via the rear connecting aperture 254.

[0136] The body 240 defines, on the abutting surface 242, a front recess 256 toward the front end thereof, and a rear recess 257 toward the rear end thereof. Thus, the body 240 has a varying width, with the width being larger at a center thereof (i.e., proximate to the receiving aperture 246 and the tongue 250), and the width being smaller at the front and rear ends thereof (i.e., proximate to the front and rear connecting apertures 252, 254). As best seen in Figure 12, and as described hereabove with reference to the inner link assembly 102, the change in width of the body 240 results in the abutting surface 242 at the front and rear ends being laterally offset from the abutting surface 242 at the center of the body 240. As mentioned above, it can be said that the links 210, 212, 214, 216 are, alternatingly, laterally offset from one another.

[0137] The three secondary intermediate links 214 are all the same, and are similar to the primary intermediate links 212. Features of the secondary intermediate links 114 similar to the features of the primary intermediate links 112 have been labeled with the same reference numerals and will not be described in detail again. The secondary intermediate links 214 notably differ from the primary intermediate links 114, in that the body 240 of the secondary intermediate links 214 has a constant width (i.e., the body 240 of the secondary intermediate links 214 does not define the receiving recess 245 or the front and rear recesses 256, 257).

[0138] The rear extremity link 216 is similar to the front extremity link 210 (mirror image thereof). Thus, features of the rear extremity link 216 similar to the features of the front extremity link 210 have been labeled with the same reference numerals, and will not be redescribed herewith.

[0139] When the outer link assembly 104 is assembled, the front extremity link 210, the primary and secondary intermediate links 212, 214 and the rear extremity link 216 are pivotally connected to one another via rivets 260. In some embodiments, the rivets 260may be welded to some of the links 210, 212, 214, 216. It is contemplated that in other embodiments, an other type of fastener could be used to pivotally connect the links to one another. In some embodiments, a bearing or a bushing may be provided in the connecting apertures 232, 252, 254 for providing a pivotal connection.

[0140] In more detail, the front extremity link 210 is pivotally connected to the primary intermediate link 212 via one of the rivets 260 that extends through the connecting aperture 232 of the front extremity link 210 and through the front connecting aperture 252 of the primary intermediate link 212. The primary intermediate link 212 is further pivotally connected to the secondary intermediate link 214 via one of the rivets 260 that extends through the rear connecting aperture 254 of the primary intermediate link 212 and through the front connecting aperture 252 of the secondary intermediate link 214. The secondary intermediate link 212 is further pivotally connected to an other one of the secondary intermediate links 214 via one of the rivets 260 that extends through the rear connecting aperture 254 of the secondary intermediate link 212 and through the front connecting aperture 252 of the other one of the secondary intermediate link 214. The remaining primary and secondary intermediate links 212, 214 and the rear extremity link 216 are further connected to one another as described hereabove.

[0141] Referring to Figures 4, 5A, 6 and 13, the support members 106 will now be described in greater detail. In the present embodiment, there are seven support members 106. It is understood that as the number of links in the inner and outer link assemblies 102, 104 varies, the number of support member 106 would vary accordingly. Each one of the support members 106 is configured to connect to one of the links of the inner link assembly 102 and a corresponding one of the links of the outer link assembly 104.

[0142] As all the support members 106 are the same, only the support member 106 that is connected to the front extremity links 110, 210 will be described in detail herewith. The support member 106, which is sized to be received in the spacing 63, has a head portion 300, a body portion 302 and a connecting portion 304.

[0143] The head portion 300 is sized to fit within the receiving recess 235 of the body 220. The head portion 300 is also sized to be greater than the receiving aperture 236.Thus, as will be described below, when the support member 106 is received through the receiving aperture 236, the head portion 300 can abut the body 220, thereby limiting movement of the support member 106 relative to the front extremity link 210.

[0144] The body portion 302 extends from the head portion 300, and is sized to extend across part of the width of the endless track 50. Also, the body portion 302 is sized to fit within the spacing 63. In some embodiments, the body 302 is generally planar.

[0145] The connecting portion 304 extends from the body portion 302 and is configured to threadedly engage the threaded aperture 128 defined in the shoulder 126 of the body 120.

[0146] With reference to Figures 3 and 4, the bridging member 108 will now be described in greater detail. As will be described in greater detail below, the bridging member 108 is configured to connect to at least some of the support members 106 so as to be positioned longitudinally in-line with, and over, the damaged area 80. The bridging member 108 can serve to provide continuity and support to the damaged endless track 50 and to prevent and / or limit further damage to the damaged area 80 (e.g., prevent the tear to further split and / or crack open). In some embodiments, the bridging member 108 could also provide traction should the damaged area 80 of the endless track 50 include damage to the traction lugs 70. Although a single bridging member 108 is shown in the accompanying Figures, it is contemplated that the repair assembly 100 may include two or more bridging members 108 depending, in some instances, on the size of the damages area.

[0147] The bridging member 108 has a body 350. The body 350 defines a front laterally extending aperture 352, a rear laterally extending aperture 354, and a laterally extending channel 356 disposed longitudinally between the front and rear laterally extending apertures 352, 354. A distance between the front laterally extending aperture 352 and the laterally extending channel 356 corresponds to the driving lug pitch PDL. Likewise, a distance between the rear laterally extending aperture 354 and the laterally extending channel 356 also corresponds to the driving lug pitch PDL. The front laterally extendingaperture 352, the rear laterally extending aperture 354 and the laterally extending channel 356 are sized to receive support members 106 therethrough.

[0148] The body 350 further has a front portion 360 and a rear portion 362. The front and rear portions 360, 362 are shaped to accommodate for a shape of the traction lugs 70. In the illustrated embodiment, the front and rear portions 360, 362 are raised portions. Thus, as the shape of the traction lugs 70 varies from one embodiment to another, a shape of the portions 360, 362 would vary accordingly. In some embodiments, the body 350 may be generally complementary to the traction lugs 70. Alternatively, in other embodiments, the body 350 could be generic so as to be useable with a variety of different endless tracks. The front portion 360 is disposed between the front laterally extending aperture 352 and the laterally extending channel 356, whereas the rear portion 362 is disposed between the laterally extending channel 356 and the rear laterally extending aperture 352. It is contemplated that in some embodiments, the body 350 could have a single portion or three or more portions.

[0149] The body 350 is made from a flexible material, so that the bridging member 108 may deform as it moves around the drive wheel assembly 32 and / or the idler wheel assembly 34. In some embodiments, the bridging member 108 is made from a polymeric material. In other embodiments, the body 350 may be made of metal that is sufficiently flexible to follow the curvature of the endless track around the drive and idler wheel assemblies 32, 34.

[0150] Referring mostly to Figures 3 and 4, the repair assembly 100 as it is connected to the damaged endless track 50 will now be described in greater detail. As will become apparent from the below, a method for repairing the damaged endless track 50 includes installing the inner link assembly 102 to the inner lateral side 56, installing the outer link assembly 104 to the outer lateral side 58, and connecting the support members 106 to the inner and outer link assemblies 102, 104.

[0151] It will be appreciated that in some embodiments, the inner link assembly 102 and / or the outer link assembly 104 may be provided with the respective links already connected to one another. Alternatively, the links may be connected to one another by auser. In either embodiment, the user may selectively decide the length of the repair assembly 100.

[0152] The repair assembly 100 is positioned, relative to the endless track 50, such that central links of each of the inner and outer link assemblies 102, 104, which are the primary intermediate links 112, 212 in the present embodiment, are longitudinally aligned with the damaged area 80. In some embodiments, the repair assembly 100 could be configured to extend about two or three pitches in either direction from the damaged area.

[0153] The inner link assembly 102 is connected to the inner lateral surface 56 of the endless track 50. More specifically, the abutting surfaces 122 of the front and rear extremity links 110, 116 and the abutting surfaces 142 of the primary and secondary intermediate links 112, 114 abut the inner lateral surface 56. Additionally, the shoulders 126, 146 are received into corresponding spacings 72, and the tongues 130, 150 are received in corresponding inner recesses 63. Due to the configuration of the links 110, 112, 114, 116, when the inner link assembly 102 is not held by a user, the inner link assembly 102 generally stays in position, due to the shoulders 126, 146 and the tongues 130, 150 engaging with the endless track 50. As will be described in greater detail below, this can facilitate the connection of the repair assembly 100 to the endless track 50.

[0154] The outer link assembly 104 is connected to the outer lateral surface 58 of the endless track 50. More specifically, the abutting surfaces 222 of the front and rear extremity links 210, 216 and the abutting surfaces 242 of the primary and secondary intermediate links 212, 214 abut the outer lateral surface 58. The links 210, 212, 214, 216, are positioned such that the tongues 230, 250 are received in corresponding outer recesses 65, and that the receiving apertures 226, 246 are aligned with corresponding spacings 72.

[0155] The bridging member 108 is positioned over the damaged area 80. The front and rear portions 360, 362 cover the traction lugs 70 proximate to the damaged area 80. In some embodiments, the body 350 may be configured to snap onto the traction lugs 70.

[0156] The support members 106 are then connected to the respective links of the inner and outer link assemblies 102, 104. Some of the support members 106 are alsoconnected to the bridging member 108. As the support member 106 connects to respective links of the inner and outer link assemblies 102, 104 in a similar fashion, only the connection of one support member 106 being connected to the front extremity links 110, 210 will be described herewith.

[0157] The support member 106 is received through the receiving aperture 226 and through the spacing 72 with which the receiving aperture 226 is aligned. Eventually, the connecting portion 304 reaches the shoulder 126 that is received in the spacing 72, at which point the connecting portion 304 is fastened to the threaded aperture 128. The presence of the shoulder 126 can increase the thread engagement between the support member 106 and the front extremity link 110, which reinforces the connection therebetween. The shoulder 126 further offsets the connection between the front extremity link 110 and the support member 106 from the edge of the endless track 50, where said connection could have been subjected to higher stresses. Finally, as mentioned above, the presence of the shoulder 126 makes it so that the user may not have to hold the front extremity link 110 in position as the support member 106 is being received into the spacing 72. Thus, it can be said that the support member 106 is connected to the front extremity link 110 by an inner interface, where the inner interface includes the threaded aperture 128 and the connecting portion 304. As will be described below, it is contemplated that the inner interface may vary from one embodiment of the repair assembly 100 to another. Additionally, the support member 106 is connected to the inner and outer link assemblies 102, 104 from the outer lateral surface 58, notably due to the presence of the frame 22 of the vehicle 20 on the inner lateral surface 56.

[0158] Eventually, the head portion 300 is received in the receiving recess 224, and abuts the body 220 of the front extremity link 210, thereby preventing the support member 106 from further being inserted into the receiving aperture 226. In some embodiments, the abutment of the head portion 300 with the body 120 can indicate that the support member 106 is connected to the front extremity links 110, 210. It can thus be said that the support member 106 is connected to the front extremity link 210 by an outer interface, where the outer interface includes the receiving recess 224, the receiving aperture 226, and the headportion 300. As will be described below, the outer interface may vary from one embodiment of the repair assembly 100 to another.

[0159] The secondary intermediate members 214 does not define any receiving recess. However, due to the secondary intermediate members 214 being laterally offset from the primary intermediate members 212 and due to the depth of the receiving recesses 224, the links 210, 212, 214, 216 are operationally aligned. That is, when the repair assembly 100 is assembled, the head portion 300 of all the support members 106 are generally laterally aligned with one another. This can ensure that all support members 106 have the same size (i.e., no need for special support members 106 to accommodate for the various sizes). Additionally, the present configuration can assist in reducing the lateral width occupied by the repair assembly 100 when it is connected to the inner and outer assemblies, such that the repair assembly 100 can be used despite the small clearance provided between the frame 22 and the skirts 24. The remaining links can be connected with the remaining support members 106 in a similar fashion.

[0160] It will be noted that some of the support members 106 can be fastened to the bridging member 108. More specifically, one of the support members 106 is received into the receiving aperture 352, an other one of the support members 106 is received into the receiving channel 356 and an other one of the support members 106 is received in the receiving aperture 354.

[0161] It will be appreciated that the above steps can be done in varying order without departing from the scope of the present technology. For example, in some embodiments, one or more support members 106 can be connected to corresponding links of the outer assembly 104 before connecting the outer assembly 104 to the endless track 50.

[0162] As mentioned above, the repair assembly 100 according to the present technology can be used with vehicles that have a small lateral clearance, the repair of which cannot be done with repair assemblies that are known in the art. For example, with reference to Figure 14, in which a conventional repair assembly 99 is shown connected toa vehicle with a skirt, the repair assembly 99 is too wide to be used with said vehicle, as parts of the repair assembly 99 would abut against the skirt and / or the frame of the vehicle.

[0163] It will also be appreciated that the repair assembly 100 can be used to repair the damaged endless track 50 without having to replace the entire endless track 50, without having to use any special tools. This repair assembly 100 can also be installed efficiently.

[0164] The repair assembly 100, when connected to the endless track 50, extends laterally beyond each of the inner and outer lateral surfaces 56, 58 by between about 15 mm and 30 mm. In some embodiments, the repair assembly may extend laterally beyond each of the inner and outer lateral surfaces 56, 58 by between about 19 mm and about 26 mm. In some embodiments, the repair assembly may extend laterally beyond each of the inner and outer lateral surfaces 56, 58 by about 19 mm. In some embodiments, the repair assembly may extend laterally beyond each of the inner and outer lateral surfaces 56, 58 by about 20 mm. In some embodiments, the repair assembly may extend laterally beyond each of the inner and outer lateral surfaces 56, 58 by about 21 mm. In some embodiments, the repair assembly may extend laterally beyond each of the inner and outer lateral surfaces 56, 58 by about 22 mm. In some embodiments, the repair assembly may extend laterally beyond each of the inner and outer lateral surfaces 56, 58 by about 23 mm. In some embodiments, the repair assembly may extend laterally beyond each of the inner and outer lateral surfaces 56, 58 by about 24 mm. In some embodiments, the repair assembly may extend laterally beyond each of the inner and outer lateral surfaces 56, 58 by about 25 mm. In some embodiments, the repair assembly may extend laterally beyond each of the inner and outer lateral surfaces 56, 58 by about 26 mm.

[0165] In an embodiment where the lateral width of the endless track 50 is about 14 inches, the ratio between the lateral distance between laterally outermost points of the repair assembly over the lateral width of the endless track 50 could be 1.105. In an embodiment where the lateral width of the endless track 50 is about 16 inches, the ratio between the lateral distance between laterally outermost points of the repair assembly over the lateral width of the endless track 50 could be 1.1092. In an embodiment where the lateral width of the endless track 50 is about 20 inches, the ratio between a lateral distancebetween laterally outermost points of the repair assembly over the lateral width of the endless track 50 could be 1.074. In an embodiment where the lateral width of the endless track 50 is about 22 inches, the ratio between the lateral distance between laterally outermost points of the repair assembly over the lateral width of the endless track 50 could be 1.067. In an embodiment where the lateral width of the endless track 50 is about 21 inches, the ratio between the lateral distance between laterally outermost points of the repair assembly over the lateral width of the endless track 50 could be 1.072. In an embodiment where the lateral width of the endless track 50 is about 22 inches, the ratio between the lateral distance between laterally outermost points of the repair assembly over the lateral width of the endless track 50 could be 1.062.

[0166] In an embodiment where a lateral width of the endless track 50 is 22 inches, the ratio between the lateral distance between laterally outermost points of the repair assembly over the lateral width of the endless track 50 could be 1.075, 1.078, 1.082, or 1.085.

[0167] As opposed to conventional repair assemblies, the smaller width of the repair assembly 100 makes it such that it can be used with the vehicle 20 (which has a small lateral clearance around the track systems 30 due to the skirts 24 for example). One conventional repair assembly 99 is illustrated in Figure 14. The repair assembly 99 is too wide to be used with a vehicle having a skirt.

[0168] During operation, the tongues 130, 150, 230, 240 can prevent the repair assembly 100 from moving away from the ground-engaging surface 54 (i.e., pulled away at least radially from the endless track 50). It can also be said that the tongues help the repair assembly 100 to follow the curvature of the endless track 50 around the drive wheel and the idler wheel assembly. It is contemplated that in some embodiments, only some of the links 110, 112, 114, 116, 210, 212, 214, 216 may have tongues. For example, in some embodiments, the tongues may be present in an alternating fashion.

[0169] The inner and outer link assemblies 102, 104 can prevent the repair assembly 100 from moving away at least laterally from the inner and outer lateral surfaces 56, 58.

[0170] The support members 106 can ensure that the repair assembly 100 generally does not move relative to the endless track 50.

[0171] The longitudinal offset of the support members 106 from the connection points (e.g., apertures 152, 154) between adjacent links can simplify manufacturing, assembly and reduce costs of the repair assembly 100. For example, the support member 106 can be replaced, when required, without having to disconnect any adjacent links.

[0172] Referring to Figures 15 to 18, an alternative embodiment of the repair assembly 100, namely repair assembly 1000, will now be described in greater detail with reference to the damaged endless track 50. Features of the repair assembly 1000 similar to those of the repair assembly 100 will not be redescribed herewith.

[0173] In this embodiment, the repair assembly 1000 includes the inner link assembly 1102, the outer link assembly 1104, support members 1106 and a bridging member 1108.

[0174] The inner link assembly 1102 includes the front extremity link 1110, the three primary intermediate links 1112, the two secondary intermediate links 1114 and the rear extremity links 1116.

[0175] In this embodiment, the bodies 1120 of the front and rear extremity links 1110, 1116 do not have the shoulder 126. Instead, each body 1120 defines an aperture 1126 configured to receive a fastener 1127 therein.

[0176] The bodies 1140 of the primary intermediate links 1112 also do not have the shoulder 146. Instead, each body 1140 has a connecting segment 1146 that defines two laterally spaced apertures 1148. It is contemplated that there could be a single or three or more laterally spaced apertures 1148 in other embodiments. Both of the laterally spaced apertures 1148 extend generally vertically (radially). It can be said that the laterally spaced apertures 1148 may extend generally radially (with reference to the track system 30). In other embodiments, the laterally spaced apertures 1148 may extend laterally or longitudinally. The laterally spaced apertures 1148 are configured to receive fasteners 1149 therein.

[0177] The bodies 1140 of the secondary intermediate links 1114 also do not have the shoulder 146. Instead, each body 1140 defines, like the front extremity link 1110, an aperture 1156 configured to receive one of the fasteners 1127 therein.

[0178] Thus, it can be observed that consecutive links 1110, 1112, 1114, 1116 have alternating configurations. It is contemplated that in some embodiments, all of the links 1110, 1112, 1114, 1116 could have the connecting segment. In other embodiments, all of the links 1110, 1112, 1114, 1116 could define the aperture configured to receive the fastener.

[0179] The outer link assembly 1104 includes the front extremity link 1210, the three primary intermediate links 1212, the two secondary intermediate links 1214 and the rear extremity links 1216. As will become apparent from the below, the configuration of the outer link assembly 1104 alternates with respect to the configuration of the inner link assembly 1102.

[0180] The bodies 1220 of the front and rear extremity links 1210, 1216 do not define the receiving apertures 1226. Instead, each body 1220 has a connecting segment 1226 that defines two laterally spaced apertures 1228 (Figure 16), similar to the laterally spaced apertures 1148. It is contemplated that in other embodiments, there could be a single aperture or three or more apertures. Both of the laterally spaced apertures 1228 extend generally vertically. The laterally spaced apertures 1228 are configured to receive fasteners 1149 therein.

[0181] The bodies 1240 of the primary intermediate links 1212 does not have the connecting segments 1146. Instead, each body 1240 of the primary intermediate links 1212 defines an aperture 1246 configured to receive one of the fasteners 1127 therein.

[0182] The bodies 1240 of the secondary intermediate links 1214 do not define the receiving apertures 1246. Instead, each body 1240 of the secondary intermediate links 1214, like the primary intermediate links 1112, has a connecting segment 1246 that defines two laterally spaced apertures 1248. It is contemplated that in other embodiments, there could be a single aperture or three or more apertures. Both of the laterally spaced apertures1248 extend generally vertically. The laterally spaced apertures 1248 are each configured to receive one of the fasteners 1149 therein.

[0183] It is contemplated that in some embodiments, all of the links 1210, 1212, 1214, 1216 could have the connecting segment. In other embodiments, all of the links 1210, 1212, 1214, 1216 could define the aperture configured to receive the fastener.

[0184] In the illustrated embodiments, the support members 1106 are all similar, but are disposed in an alternating orientation relative to one another due to the alternating configuration of the inner and outer links assemblies 1102, 1104.

[0185] Still referring to Figures 16, 17 and 18, only one support member 1106 will be described herewith. The support member 1106 has a connecting portion 1300 at one end, a connecting portion 1302 at the other end, and a body portion 1304 extending between the two connecting portions 1300, 1302.

[0186] The connecting portion 1300 defines a recess 1310 that is configured to be complementary to the connecting segments 1146, 1226, 1246. Additionally, the connecting portion 1300 defines, above the recess 1310, two laterally spaced extending apertures 1312 that extend generally vertically (radially). It is contemplated that the number and / or the orientation of the apertures 1312 may vary. The apertures 1312 are configured to align with corresponding ones of the apertures 1148, 1228, 1248, and are configured to receive the fasteners 1149 therein.

[0187] The connecting portion 1302, on the other end, defines an aperture 1320 that extends generally laterally. The aperture 1320 is configured to align with a corresponding one of the apertures 1126, 1156, 1246, and receive one of the fasteners 1127, therein.

[0188] The body portion 1304, which is shaped to fit within the spacing 72, extends in the lateral direction such that the connecting portions 1300, 1302 are positioned to connect to the inner and outer link assemblies 1102, 1104. In the present embodiment, being that the traction lugs 70 and the spacings 72 of the endless track 50 are generally linear, the body portion 1304 is also generally linear. If the repair assembly 1000 were to be used for the endless track 50’, which is shown in Figures 2C and 2D, where the tractionlugs 70’ and the spacings 72’ are non-linear (e.g., chevron-shaped), the body portion 1304 would be generally chevron-shaped. That said, a cross-section of the support element 1106 generally has a trapezoidal shape to generally match with the shape of the spacing 72.

[0189] The body portion 1304 of some of the support members 1106 may define apertures 1330 configured to receive fasteners therein for connecting to the bridging member 1108.

[0190] The bridging member 1108 is similar to the bridging member 108. The bridging member 1108 notably differs from the bridging member 108 in that the bridging member 1108 defines a front laterally extending channel 1352 (instead of the front laterally extending aperture), an intermediate extending channel 1354, and a rear laterally extending channel 1356 (instead of the front laterally extending aperture). The presence of the channels instead of apertures, can facilitate assembly of the repair assembly 1000, as the support members 1106 can be inserted into the channels 1352, 1354, 1356 at once (instead of having to slide the supports members 1106 into position via an aperture).

[0191] The bridging member 1108 also defines apertures 1358 configured to be aligned with the apertures 1330 of the body portion 1304.

[0192] To connect the repair assembly 1000 to the endless track 50, the inner link assembly 1102 is disposed on the inner lateral surface 56 of the endless track 50, and the outer link assembly 1104 is disposed on to the outer lateral surface 58 of the endless track 50 as described hereabove with reference to the repair assembly 100. One advantage of the repair assembly 1000 is that the inner and outer link assemblies 1102, 1104 are reversible. That is, the inner link assembly 1102 can easily be connected to the outer lateral surface 58 and the outer link assembly 1104 can easily be connected to the inner lateral surface 56.

[0193] The bridging member 1108 is positioned over the damaged area 80.

[0194] The support members 1106 are then connected to respective links of the inner and outer link assemblies 1102, 1104, with some of the support members 1106 connecting to the bridging member 1108. As the support member 1106 connects to respective links of the inner and outer link assemblies 1102, 1104 in a similar fashion, onlythe connection of one support member 1106 being connected to the front extremity links 1110, 1210 will be described herewith.

[0195] The support member 1106 is connected to the front extremity link 1110 via the connecting portion 1302. More specifically, the aperture 1320 of the connecting portion 1302 is aligned with the aperture 1126 of the front extremity link 1110, and the fastener 1127 is received through the aperture 1126 and then fastened to aperture 1320. Thus, it can be said that the support member 1106 is connected to the front extremity link 1110 by an inner interface, where the inner interface includes the aperture 1126 of the front extremity link 1110, the aperture 1320 of the support member 1106 and the fastener 1127. It will be noted that the inner interface alternates in configuration between consecutive support members 1106.

[0196] The support member 1106 is connected to the front extremity link 1210 via the connecting portion 1300. More specifically, the connecting segment 1246 of the front extremity link 1210 is received into the recess 1310, such that the apertures 1312 of the support member 1106 are aligned with the aperture 1248 of the front extremity link 1210. Then, the fasteners 1149 are received through the apertures 1312, 1248. Thus, it can be said that the support member 1106 is connected to the front extremity link 1210 by an outer interface, where the outer interface includes the connecting segment 1246, the recess 1310, and the apertures 1312, 1248. It will be noted that the outer interface alternates in configuration between consecutive support members 1106.

[0197] Some of the support members 1106 are fastened to the bridging member 1108 via the fasteners (not shown) that are received through the apertures 1330 defined in the body portions 1304 of the support elements 1106 and through the apertures 1358 defined in the bridging member 1308.

[0198] It will be appreciated that the support members 1106 can be positioned into their corresponding recesses 72 radially, such that it is not necessary to slide the support member 1106 radially into position. This can reduce the lateral clearance required to install the repair assembly 1000. By the same token, if one of the support member 1106 is damaged, it can quickly be replaced by another support member 1106, without having toslide the damaged support member 1106 through any opening, which can be difficult depending on the type of damage that the support member 1106 sustained. For example, if the support member 1106 is bent out of shape, it may be difficult to pass it through an opening.

[0199] It will be appreciated that the above steps can be done in varying order without departing from the scope of the present technology. For example, in some embodiments, the bridging member 1108 may be connected to the support members 1106 before the bridging member 1108 is connected to the endless track 50.

[0200] With reference to Figures 19 and 20, an alternative embodiment of the repair assemblies 100, 1000, namely repair assembly 2000, will now be described in greater detail. Features of the repair assembly 2000 similar to those of the repair assemblies 100, 1000 will not be redescribed herewith.

[0201] In this embodiment, each of the links 2110, 2112, 2114, 2116 of the inner link assembly 2102 has two pulley wheels 2002, and each of the links 2210, 2212, 2214, 2216 of the outer link assembly 2104 also has the two pulley wheels 2002. It is contemplated that the number of pulley wheels 2002 per link may vary from one embodiment to another. All the pulley wheels 2002 of the inner link assembly 2102 are operatively interconnected by a flexible member 2004. Likewise, all the pulley wheels 2002 of the outer link assembly 2104 are also operatively interconnected by another flexible member 2004. Both of the flexible members 2004 are braided cords, but it is contemplated that other types of lines may be used. In some embodiments, the flexible members 2004 may be made of kevlar, from Ultra-High Molecular Weight Polyethylene or from spring steel. The pulley wheels 2002 and the flexible members 2004 can assist in distributing the load that the repair assembly 2000 is subjected to during operation, thereby reducing a maximal load that damaged area 80 may be subjected to. It is contemplated that the pulley wheels 2002, 2004 could be integrated to the repair assembly 100 and / or to the repair assembly 1000. The use of pulley wheels 2002 and flexible members 2004 can be advantageous in that the flexible members 2004 can easily be replaced if it becomesdamaged. Replacing these flexible members 2004 can also be cheaper than replacing other members.

[0202] Modifications and improvements to the above-described embodiments of the present invention may become apparent to those skilled in the art. The foregoing description is intended to be exemplary rather than limiting. The scope of the present invention is therefore intended to be limited solely by the appended claims.
