CONDUCTION GUIDE DEVICE

Description

[0001] The invention relates to a cable guide device for connecting a cable harness to a carrier element movable relative to a vehicle, according to the features in the preamble of claim 1. Furthermore, the invention is also implemented in combination with a semi-trailer, trailer, or articulated vehicle. Document WO 2004 / 020321 A1 discloses a cable guide device of this type.

[0002] Semi-trailer trucks typically consist of a tractor unit and a semi-trailer, which are detachably connected by means of a fifth wheel coupling mounted on the tractor unit and a kingpin attached to the semi-trailer. This makes it possible to park a semi-trailer connected to the tractor unit and load another semi-trailer in its place. For such coupling operations, the driver usually has to get out and mechanically open the fifth wheel coupling to uncouple, or, after coupling, check that the kingpin is correctly inserted into the fifth wheel coupling.

[0003] An articulated vehicle usually consists of a towing vehicle and a trailer coupled to it, which is releasably attached to a trailer coupling of the towing vehicle by means of a drawbar.

[0004] An articulated vehicle, for example, is an articulated bus, such as those used in local public transport. An articulated vehicle can also be a wheel loader, a road roller, or an articulated dump truck. Articulated vehicles have in common that they are designed from a first and second vehicle section with a pivot joint in between. The first and second vehicle sections cannot be separated from each other during operation. When the articulated vehicle corners, the first and second vehicle sections change their relative position to each other.

[0005] In the past, there have been attempts to automate the coupling and uncoupling process of, for example, a semi-trailer to the towing vehicle and to connect supply lines in the process. For example, DE 10 2004 024 333 A1 describes a plug-in coupling system in which, during the coupling of the semi-trailer and towing vehicle, a wedge-shaped pivoting frame mounted so that it can pivot relative to the kingpin is retracted into an entry opening of the fifth wheel coupling and is held there after the kingpin is locked. When the semi-trailer is cornering, the wedge-shaped pivoting frame pivots relative to the semi-trailer, so the supply lines must be sufficiently long to avoid being snagged during sharp cornering. However, when driving straight ahead, the supply lines sag and could be damaged.

[0006] For this reason, DE 10 2004 044 992A1 proposes attaching a cable storage device to the semi-trailer, in which the supply lines exiting the wedge-shaped pivoting frame are wound onto a spring-loaded drum pulley and unwound under tension when cornering. A significant disadvantage of this known cable storage device is the comparatively large installation space required and the difficulty of accommodating a cable harness with an ever-increasing number of supply lines on the drum pulley without exceeding the minimum permissible bending radius specified for the cable harness.

[0007] The object of the invention was to provide a compact cable guide device which is suitable for ensuring a small sag of a cable harness with a large diameter.

[0008] The object is achieved according to the invention with the features of claim 1. A spring element is understood to be a component that is reversible under the expected operating loads and that can be stretched in its axial extent between a maximum and a minimum length. The spring element can, in principle, be made of spring steel, plastic, or a rubber compound. The cable harness is always loosely placed in, on, or on the spring element and is otherwise not connected to it.

[0009] The term "loose" refers to a mechanical decoupling of the spring element and the cable harness. Consequently, the spring element can lengthen or shorten independently of the cable harness. In the axial direction of the cable harness, relative movement to the spring element can occur. The cable harness is supported by the spring element and only needs to overcome the sliding friction resulting from its weight for axial movement. In the radial direction, the cable harness is guided by the spring element with a small degree of movement.

[0010] When cornering, the support element changes its position relative to the cable storage, so that the distance between the support element and the cable storage increases, and the cable harness must bridge this larger distance. In this situation, part of the cable harness located in the cable storage is pulled out of the cable storage by the support element. When the vehicle travels straight ahead again, the distance between the support element and the cable storage decreases, so that the cable harness needs to bridge a smaller distance. In this situation, the cable harness is partially pushed back into the cable storage by the support element.

[0011] The spring element ensures that the cable harness is always supported and does not sag downwards, preventing it from colliding with other vehicle parts. When the cable harness is pushed into the cable storage, the spring element prevents it from drifting sideways and ensures a smooth entry into the cable storage.

[0012] The spring element is expediently attached to the support element and / or the cable storage unit. This holds the spring element fixed in its axial direction, and the cable harness slides into the cable storage unit without being coupled to it. If the spring element is attached to both the support element and the cable storage unit, this results in the additional advantage that the support element is forcibly aligned due to the spring preload of the spring element, for example, after uncoupling. Especially if the support element is a wedge-pivoting frame, this forced alignment ensures that it is in the correct position for re-coupling.

[0013] Advantageously, the spring element is a coil spring, an expandable hose, or an elastic bellows. The coil spring, expandable hose, or bellows can completely surround the cable harness in the circumferential direction, thereby providing particularly effective guidance and protection in all directions.

[0014] The spring element should have an anti-twist feature or be installed in a manner that prevents it from twisting around its longitudinal axis. This ensures that the spring element, especially if it is designed as a helical spring, cannot unscrew itself from its mounting by rotating around its longitudinal axis.

[0015] Preferably, the cable harness is inserted into the cable storage device as a loop. The loop can be formed, for example, in a U-shape, an S-shape, an Ω-shape, or as a tightening loop.

[0016] The loop is spanned in particular by an incoming section and an outgoing section and encloses a maximum loop angle of 270°, particularly preferably a maximum of 205°, most preferably 200°, regardless of the position of the support element. With an embodiment of the loop as a tightening loop, loop angles of 360° to 400° are thus feasible. The incoming section moves out of the cable storage device when the support element pivots and tightens the loop. The outgoing section is preferably secured at the end in or on the cable storage device. When traveling straight ahead, the incoming section has predominantly moved into the cable storage device.

[0017] Conveniently, the direction of the loop is always the same, regardless of the relative position of the support element. The incoming and outgoing sections typically do not intersect in a U-shaped, S-shaped, or Ω-shaped loop. In a tightening loop, the incoming and outgoing sections intersect within the cable storage.

[0018] When the support element is in a straight-ahead position, the loop within the cable storage can have a maximum loop length. The loop is pushed backward through the incoming section, thereby accommodating a larger section of the cable bundle within the cable storage.

[0019] In a curved position of the support element, however, the loop may have a minimal length within the cable storage. Part of the cable strand has been pulled out of the cable storage by the incoming section, and the loop has changed its position in the opposite direction, thereby reducing its radius.

[0020] Ideally, the cable storage system comprises a box-shaped or pot-shaped housing, and the cable harness is placed on a base wall of the box-shaped or pot-shaped housing. When the loop changes position, it slides over the base wall, eliminating the need for moving parts and clamping elements.

[0021] Advantageously, the spring element is attached to the support element with a front guide bracket and / or to the cable storage unit with a rear guide bracket. The front and rear guide brackets pivot together with the spring element, thereby reducing the risk of irreversible kinks in the spring element.

[0022] A particularly preferred embodiment is one in which the front and / or rear guide bracket is mounted by means of a pivot bearing about a pivot axis that is vertical in the installed position. The pivot bearing of the front guide bracket can engage, in particular, the support element, and the pivot bearing of the rear guide bracket can engage the housing of the cable storage device.

[0023] According to a further embodiment, guide elements diverging outward are arranged on opposite sides of the front and / or rear guide bracket. In the event of a particularly strong pivoting of the support element, the spring element on the inside of the curve engages the guide element located there, further reducing the risk of kinking of the spring element.

[0024] Ideally, the guide elements project backward and / or forward relative to the front and / or rear guide brackets in the installed position, i.e., in the rearward direction relative to the forward travel of the semi-trailer. The inner sides of the guide elements facing each other can be designed with an opposing curvature. This curvature should be as continuous as possible to prevent kinks in the spring element.

[0025] The cable harness preferably comprises several supply lines that are enclosed and / or held together by at least one protective hose. The protective hose protects the supply lines from mechanical damage, particularly when they are constantly sliding against the spring element and the housing, for example, against its base wall. A particularly advantageous design for the protective hose is a surface that provides a particularly favorable coefficient of friction. This, in turn, reduces wear and enables a particularly smooth sliding movement of the cable harness into and out of the cable storage unit.

[0026] A carrier element plug element is expediently provided on the carrier element and / or a cable storage plug element is provided on or adjacent to the cable storage. The carrier element plug element enables an electrical, pneumatic, and possibly also hydraulic connection to the supply circuit of the towing vehicle. The carrier element plug element is often designed as a plug, and the complementary component of the towing vehicle is designed as a socket for safety reasons, as this is live. The carrier element plug element is connected or disconnected during each coupling and uncoupling process. The cable storage plug element enables a connection of the cable routing device to the semi-trailer's on-board electrical system, typically via a complementary plug component of the semi-trailer, and is usually designed as a socket, as this is live.As a rule, the cable storage connector element is only disconnected for repair and maintenance purposes.

[0027] Advantageously, the support element is a wedge-shaped pivot frame that can be attached to a semi-trailer or a connector bracket that can be attached to a trailer. The cable storage unit is then designed, together with automated coupling systems, to connect the supply lines of the semi-trailer or trailer to the towing vehicle.

[0028] The invention also extends to a combination of a cable guide device explained above with a vehicle designed as a semi-trailer, wherein the support element is a wedge pivot frame pivotable about a kingpin.

[0029] The cable storage unit is logically located beneath the semi-trailer's floor. This installation position allows direct access for assembly and repair purposes. Furthermore, the cable storage unit and the entire cable routing system can be installed without major structural modifications to the semi-trailer.

[0030] A particularly preferred embodiment is one in which the cable storage unit is attached to the underside of a trailer floor or to a chassis component or to an attachment part of the semi-trailer, such as the landing gear. A chassis component is understood to mean, in particular, a longitudinal member or cross member of the vehicle frame of the semi-trailer or the attachment brackets for the landing gear.

[0031] The loop of the cable harness can have a section leading into the cable storage unit and an section leading out, both of which are aligned toward the front of the semi-trailer. The concave side of the loop faces the front of the semi-trailer.

[0032] According to an alternative embodiment, the vehicle can also be a trailer, and the support element can be a connector bracket movably mounted relative to a drawbar. The connector bracket regularly pivots during driving, for example, when negotiating a curve, with a complementarily shaped connector socket on the towing vehicle into which it is plugged. This pivoting movement requires the cable harness to be guided along by the trailer, with the cable harness being pulled further out of the cable storage in a curve-travel position than in a straight-ahead position. The connector bracket is usually pivotally mounted relative to the trailer's drawbar.

[0033] Ideally, the cable storage unit is attached to or fixed to the drawbar of the trailer.

[0034] According to yet another embodiment, the vehicle is designed as an articulated vehicle and has a first and a second vehicle part separated from each other by a pivot joint. The support element is a collecting bracket arranged on the first vehicle part, and the cable storage unit is preferably fixedly attached to the second vehicle part. The cable storage unit enables a largely sag-free connection of the cable harness to the relatively movable collecting bracket of the first vehicle part, regardless of the relative bending position of the first and second vehicle parts.

[0035] For a better understanding, the invention is explained below with reference to 12 figures.

[0036] The Fig. 1 shows a side view of a vehicle 10 in the form of a semi-trailer 10a, which is connected by means of a kingpin 15 projecting downwards relative to a bottom side 12 of a trailer floor 11 to a schematically shown Fig. 2 und Fig. 3 shown fifth wheel coupling 16 of a towing vehicle not shown here can be retracted and locked with the fifth wheel coupling 16. The fifth wheel coupling 16 has, at its end facing the semi-trailer 10a during coupling, a V-shaped widened entry opening 17 through which the kingpin 15 is guided laterally during a further approach of the towing vehicle and the semi-trailer 10a and is finally locked in its end position.

[0037] The kingpin 15 is located in a section adjacent to the front end 14 of the semi-trailer 10a. Typically, the semi-trailer floor 11 is supported by two longitudinal members 13a running along the vehicle's longitudinal axis, which, together with other cross members (omitted for clarity), form chassis components 13.

[0038] A support element 40 in the form of a wedge pivot frame 40a is pivotably mounted on the semi-trailer 10a about the kingpin 15, via which an electrical and pneumatic connection to the towing vehicle is established, in particular during an automatic coupling process.

[0039] When the kingpin 15 is inserted into the fifth wheel coupling 16, the wedge pivot frame 40a also enters the entry opening 17 of the fifth wheel coupling 16 and is supported laterally therein due to its shape complementary to the entry opening 17.

[0040] From the wedge pivot frame 40a, a cable harness 20 runs in the rearward direction x of the semi-trailer 10a to a cable storage 50 fixedly attached to the trailer floor 11 or one of the chassis components 13. The cable storage 50 receives a part of the cable harness 20 or releases a part of the cable harness 20 depending on a relative position of the semi-trailer 10a to the fifth wheel coupling 16, thereby preventing the cable harness 20 from sagging during straight-ahead travel.

[0041] A straight-ahead position of the towing vehicle and semi-trailer 10a is in Fig. 2 can be seen. The wedge pivot frame 40a, the cable harness 20, and the cable storage 50 are essentially aligned along the longitudinal axis of the semi-trailer 10a. In this position, the cable harness 20 must bridge a comparatively small distance between the wedge pivot frame 40a and the cable storage 50. Due to its rigidity, the cable harness 20 has been partially pressed into the cable storage 50 by the wedge pivot frame 40a. A spring element 21 is arranged between the wedge pivot frame 40a and the cable storage 50 and encloses the cable harness 20 over the entire distance. The spring element 21 has its shortest axial length between the wedge pivot frame 40a and the cable storage 50.

[0042] The Fig. 3 shows an extreme cornering position, such as can occur particularly during maneuvering. The wedge pivot frame 40a has pivoted approximately 90° counterclockwise and has pulled a portion of the cable harness 20 out of the cable storage 50. The cable storage 50 thereby prevents the cable harness 20 from tearing off the wedge pivot frame 40a. The spring element 21 has correspondingly extended its axial length due to the pivoting path completed by the wedge pivot frame 40a. However, the movement of the cable harness 20 occurs independently of the expansion of the spring element 21, since they are not connected to one another. The cable harness 20 rests solely on the spring element 21 with its weight, but is otherwise not kinematically coupled to the spring element 21.

[0043] In the Fig. 4 The wedge pivot frame 40a is oriented in a straight-ahead driving position. When the semi-trailer is coupled to a towing vehicle, a wedge pivot frame connector element 41 is connected to a complementary connector element of the towing vehicle, thereby establishing at least one electrical and pneumatic connection. The wedge pivot frame connector element 41 is electrically connected to the wiring harness 20, which comprises a total of six supply lines 23a, 23b, 23c, 23d, 23e, 23f, of which four supply lines 23a, 23b, 23c, 23d are designed as electrical lines and two supply lines 23e, 23f are designed as pneumatic lines.The always multiple supply lines 23a, 23b, 23c, 23d, 23e, 23f are inserted together into a protective hose 24, which, in addition to a mechanical protective function of the supply lines 23a, 23b, 23c, 23d, 23e, 23f, also has a particularly smooth surface, which reduces the sliding friction between the line strand 20 and a spring element 21 surrounding it.

[0044] In the illustrated embodiment, the spring element 21 is a cylindrical coil spring, which is attached by its end sections to both the wedge pivot frame 40a and the cable storage 50. In the straight-ahead position, the spring element 21 is in a contracted, short position. The cable harness 20 runs loosely through the interior of the spring element 21 and rests on the spring element 21 only with its underside, subject to gravity. The cable harness 20 is attached to the wedge pivot frame 40a by means of a strain relief device 42 to prevent tensile forces of the cable harness 20 from permanently connecting to the wedge pivot frame connector element 41.

[0045] How particularly good in the Fig. 4 und Fig. 5 As can be seen, the cable storage 50 comprises a box-shaped housing 51 with a bottom wall 52 and side walls 53 projecting thereon, which in the mounted position according to Fig. 1 rest on the front side against the trailer floor 11 or a chassis component 13. The spring element 21 is fastened centrally on the side wall 53 of the housing 51 facing the wedge pivot frame 40a and the cable harness 20 passes with its incoming section 25 through an opening 55 formed in the side wall 53 (see Fig. 5 ) into the housing 51. For a particularly smooth entry and exit of the cable strand 20 into and out of the cable storage 50, a support roller 56 is laterally offset within the housing 51 and rotatably mounted adjacent to the opening 55, which support roller 56 ensures uniform movement of the incoming section 55, in particular during an extending movement thereof.

[0046] Within the housing 51 of the cable storage 50, the cable harness 20 is stored in a single loop 22 in one plane, in particular on the bottom wall 52 of the housing 51.

[0047] In the straight-ahead position of the wedge pivot frame 40a, the loop 22 has a maximum length l max . An outgoing section 26 of the cable harness 20 is connected to a cable storage connector element 54, via which, in turn, the cable storage connector element 54 can be connected to the on-board electrical system of the semi-trailer 10a. The cable storage connector element 54 is also inserted into the side wall 53 of the housing 51 facing the wedge pivot frame 40a. In the straight-ahead position, the incoming section 25 and the outgoing section 26 are located on opposite sides of the base wall 52, adjacent to its nearest side wall 53.

[0048] The Fig. 6 illustrates a situation of the cable harness 20 pulled out of the cable storage 50 in a cornering position, in which the loop 22 has migrated to the left in the image plane toward the side wall 53 facing the wedge pivot frame 40a. The radius of the loop 22 has decreased, as has its length, which has now reached a minimum loop length I min.

[0049] The Fig. 7 shows a longitudinal section of the cable harness 20 with the surrounding spring element 21. The spring element 21 is attached to the wedge pivot frame 40a by means of a front guide bracket 30 and to the housing 51 of the cable storage device 50 by means of a rear guide bracket 31. The front guide bracket 30 is identical in construction to the rear guide bracket 31. The front and rear guide brackets 30, 31 are each mounted about a vertical pivot axis Z by means of a pivot bearing 32 (see Fig. 8 ). The pivot bearing 32 of the front guide bracket 30 engages the wedge pivot frame 40a. The rear guide bracket 31 is inserted into the opening 55 of the housing 51 of the cable storage unit 50 and is mounted relative to the housing 51 by means of the associated pivot bearing 32.

[0050] Furthermore, guide elements 34 are formed on opposite sides 33 of the front and rear guide brackets 30, 31. These guide elements are curved laterally and outwardly in the rearward direction x and protrude relative to the guide brackets 30, 31. In plan view, each guide element 34, or its inner side 35 of the front or rear guide bracket 30, 31, executes an arc of approximately 90°, opposite each other and in opposite directions. Furthermore, pairs of guide elements 34 are provided on the front and rear guide brackets 30, 31, curved laterally and outwardly in the opposite direction x.

[0051] In a straight-ahead travel position of the wedge pivot frame 40a, the guide elements 34 are arranged at a distance from the spring element 21 and are therefore without function. However, as soon as a cornering position occurs, the wedge pivot frame 40a moves laterally outward relative to the cable storage device 50, and the spring element 21 would be subjected to an irreversible buckling load in the area of ​​the wedge pivot frame 40a or in the area of ​​the opening 55 of the housing 51. With the help of the front and rear guide consoles 30, 31, these initially rotate together with the fastening of the spring element 21. In an even tighter cornering position, the spring element 21 nestles against the inner side 35 of the respective guide element 34, which is on the inside of the curve, thereby largely avoiding buckling loads.

[0052] The Fig. 8 shows in an enlarged perspective view a front or rear guide console 30, 31 and Fig. 9 Its exemplary attachment to the spring element 21 by means of a spring element fastening means 36. The spring element fastening means 36 comprises bracket openings 36b formed in the opposite sides 33 of the front or rear guide bracket 30, 31, through which a U-shaped bracket 36a is inserted and secured against loss, in particular, with a securing pin 36c. The bracket 36a can, for example, be inserted from the inside, first through the coils of the spring element 21 and then through the bracket openings 36b. The associated securing pin 36c penetrates the free legs of the bracket 36a outside the front or rear guide bracket 30, 31.

[0053] It is also possible to provide the two ends of the bracket 36a with a thread, to screw a nut onto the thread instead of using a locking pin 36 and to pre-tension the bracket 36a in this way, so that the spring element 21 is pressed from the inside against the wall of the front or rear guide bracket 30, 31 and is held there in a clamping manner.

[0054] In the Fig. 10 The housing 51 of the cable storage unit 50 can be seen in a perspective view. In the side wall 53 facing the wedge pivot frame 40a, the opening 50 is located in a central position, into which the rear guide bracket 31 is inserted, through which the cable harness 20 enters the cable storage unit 50. Directly to the side of the opening 50 and next to the rear guide bracket 31, the cable storage plug element 54 is inserted into the same side wall 53, with the aid of which the cable storage unit 50 can be connected to the on-board electrical system of the semi-trailer 10a.

[0055] The Fig. 11 shows the front end of a vehicle 10 in the form of a trailer 10b, which can be coupled to a towing vehicle (not shown here) by means of a drawbar 18. On the upper side of the drawbar 18, a support element 40 is arranged as a plug bracket 40b, which is plugged into a complementarily shaped plug socket of the towing vehicle to establish an electrical and pneumatic connection. The plug bracket 40b can be pivoted about its vertical axis relative to the drawbar 18 in order to pivot along with the plug socket of the towing vehicle when cornering and to ensure a constant connection of the plug bracket 40b to the plug socket on the towing vehicle side.

[0056] The change in position of the connector bracket 40b with respect to the drawbar 18 is compensated by means of the cable storage 50 which is fixedly attached to the drawbar 18 and into which the cable harness 20 engaging the connector bracket 40b runs. The cable storage 50 corresponds structurally to that shown in the Fig. 1 bis Fig. 10 explained construction work.

[0057] In this embodiment, the cable harness 20 is also completely surrounded in the circumferential direction by the spring element 21, which is attached to both the connector bracket 40b and the cable storage 50. With the help of the spring element 21, the cable harness 20 is guided in the axial direction, can escape from the cable storage 50 when cornering and can be pushed back into the cable storage 50 when driving straight ahead due to its flexural rigidity. In the illustration of the Fig. 11 the support element 10 in the form of the plug bracket 40b is in a straight-ahead position in which the spring element 21 is contracted and a maximum section of the cable harness 20 is received by the cable storage 50.

[0058] The Fig. 12 illustrates, in a further exemplary embodiment, the attachment of the cable guide device to a vehicle 10 in the form of an articulated vehicle 10c or to its frame components. The articulated vehicle 10c has a first vehicle part 10c1 and a second vehicle part 10c2, which are connected to one another via a pivot joint 19 arranged therebetween. The articulated vehicle 10c is located in the illustration of Fig. 12 in a cornering position in which the first vehicle part 10c1 is angled to the second vehicle part 10c2 at the swivel joint.

[0059] The cable harness 20 runs from the first vehicle part 10c1 via the swivel joint 19 to the second vehicle part 10c2. Since the relative position of the first and second vehicle parts 10c1, 10c2 changes continuously during driving, it is necessary to adapt the cable harness 20 to the respective bending position of the first and second vehicle parts 10c1, 10c2. This adaptation is achieved by means of the cable storage 50. The cable harness 20 is fastened to the support element 40 in the form of a collecting bracket 40c, placed on one side on the outer circumference of the swivel joint 19, and from there runs into the cable storage 50. Over the entire course from the cable storage 50 to the collecting bracket 40c, the cable harness 20 is received by the spring element 21 and loosely deposited therein.Due to the bent position of the first and second vehicle parts 10c1, 10c2, the spring element 21 is in a stretched position, which is released during the return to the straight-ahead driving position.

[0060] In this embodiment, too, the cable harness moves in sections out of and into the cable storage solely due to its flexural rigidity, kinematically decoupled from the spring element 21, which merely supports the cable harness 21 and prevents it from sagging. Bezugszeichenliste
