Technical Field
[0001] This utility model relates to the field of track technology, and in particular to a novel track tooth, track tooth, and tracked vehicle. Background Technology
[0002] Tracked vehicles are mostly used in large engineering vehicles or tanks, as they can adapt to relatively complex road surfaces. In the field of reed harvesting, where operations often take place in muddy and swampy environments, tracked vehicles are frequently used.
[0003] Currently, most tracks used are metal tracks, which can allow movement in swampy environments, but many shortcomings remain unresolved:
[0004] First, the heavy weight of metal tracks in swampy environments, combined with the vehicle's own weight, makes it easy for the vehicle to get stuck and unable to move. To address this issue, one-piece all-rubber tracks with some flexibility have been used, which reduces weight to some extent. However, rubber tracks still contain metal wires, limiting the weight reduction, and getting stuck remains a significant concern. More importantly, prolonged operation in complex outdoor environments easily leads to broken teeth, weathering, cracking, and aging of rubber tracks, severely impacting the vehicle's ability to get out of trouble. Damaged individual track teeth cannot be replaced individually; the entire track must be replaced. Replacement frequency is directly proportional to operational intensity, resulting in frequent replacements. The high cost of a complete track contributes to the high overall cost. Furthermore, during relocation operations, all-rubber tracks are easily deformed and damaged under pressure on ordinary hard surfaces, requiring on-site replacement with metal tracks or transport by specialized vehicles, thus limiting their usability.
[0005] Secondly, regardless of whether the tracks are metal or rubber, to solve the problem of slipping and slackness, vehicles must be equipped with tensioners to tighten the tracks for propulsion. This drive structure directly affects the efficiency of track assembly and disassembly. In other words, the tensioners must be removed before the tracks can be disassembled or reassembled, making the process extremely cumbersome and inconvenient. Especially when operating in swampy areas, the tracks are prone to deformation and slippage (commonly known as "track slippage") when the vehicle tilts or gets partially stuck. Track slippage can occur approximately three times a month, and even more frequently in harsher working conditions, requiring on-site track repositioning and maintenance. However, in swampy areas, vehicles are often deeply stuck and difficult to right, making track repositioning even more challenging, directly impacting the work cycle and making maintenance extremely inconvenient.
[0006] Therefore, existing tracks need to be improved to make them lighter, less expensive, easier to maintain, and more adaptable. Utility Model Content
[0007] The purpose of this invention is to provide a track tooth, track, and tracked vehicle to solve the problems mentioned in the background art. It combines the strength of metal tracks with the toughness of rubber tracks, making it suitable for both swamps and hard surfaces. It also offers advantages such as convenient maintenance, low cost, greater durability, flexible steering, strong traction, reduced risk of derailment, and energy saving, resulting in more stable and reliable operation of the tracked vehicle.
[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0009] On the one hand, a track tooth is provided, including a strip-shaped track tooth body, wherein the track tooth body is provided with a plurality of connecting holes arranged in its radial direction for detachable connection with a track;
[0010] The track tooth body is also provided with guide teeth that extend away from the ground.
[0011] As a further improvement of this utility model, the axial end face of the track tooth body is rectangular or triangular.
[0012] As a further improvement of this utility model, the included angle of the track tooth body, which has a triangular axial end face, facing the ground is rounded.
[0013] As a further improvement of this utility model, the track tooth body has skirt portions on both sides in the axial direction, and a plurality of the connecting holes are placed on the skirt portions.
[0014] As a further improvement of this utility model, the edge of the skirt portion has a rounded corner structure.
[0015] As a further improvement of this utility model, the axial ends of the track tooth body are rounded.
[0016] On the other hand, a track is also provided, including a rubber track, wherein a plurality of track teeth are uniformly arranged along its width direction on the side of the rubber track facing the ground, and the track teeth and the rubber track are fastened together by a connector passing through the connecting hole.
[0017] As a further improvement of this utility model, the side of the rubber track away from the track tooth body is provided with a pad that is fastened to the connector.
[0018] As a further improvement of this utility model, the connecting member is a fastening bolt.
[0019] As a further improvement of this utility model, the side of the skirt portion away from the track tooth body is inclined toward the rubber track.
[0020] On the other hand, a tracked vehicle is also provided, including the vehicle body;
[0021] The vehicle body has a drive wheel and several driven wheels on both sides. The drive wheel has drive teeth arranged at equal intervals. The tooth groove between each two adjacent drive teeth meshes with the aforementioned guide teeth for transmission. The driven wheels are held by the guide teeth on both sides.
[0022] As a further improvement of this utility model, the side of the guiding tooth facing the driven wheel has an inclined structure.
[0023] As a further improvement of this utility model, the driven wheel is a rubber wheel.
[0024] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:
[0025] The track tooth structure in this application is more reasonable, providing better grip and extrication performance in muddy and swampy areas. It also allows for the individual disassembly and replacement of individual track teeth, significantly extending the overall service life of the tracks and reducing replacement costs.
[0026] This invention combines rubber tracks with metal track teeth, which not only has the advantages of the toughness and low cost of rubber tracks, but also the advantage of replacing track teeth individually to reduce costs. It also reduces weight while making it convenient to use and maintain.
[0027] By adopting the track teeth and track in this application, the tracked vehicle does not need to be equipped with a tensioner, and a stable transmission relationship can be achieved between the track, the drive wheel, and the driven wheel, which simplifies the vehicle structure and makes it more convenient and faster to replace or maintain the track on site.

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the following is a summary description. Figure 1 To be continued Figure 18 The present invention will be further described in detail with reference to embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.
[0051] Example 1
[0052] The purpose of this embodiment is to provide a track tooth that can be detachably connected to the track, and a single track tooth can be replaced individually when damaged, significantly reducing maintenance costs compared to the previous integrated track structure. Specifically, it includes a strip-shaped track tooth body 100, which has a plurality of connecting holes 101 arranged radially thereon for detachable connection with the track 200.
[0053] In other words, the orientation of the connecting holes 101 (i.e., the direction in which the connecting holes 101 face) is consistent with the radial direction of the track tooth body 100, allowing for a secure connection between the track teeth and the track through the connecting piece. Furthermore, the connection between the track tooth body 100 and the track 200 is detachable. Traditional metal or rubber tracks, however, are integrally connected to the track teeth. While metal tracks consist of multiple track plates hinged together, the track teeth and track plates are still integrally connected.
[0054] The track tooth body 100 is also provided with guide teeth 102 extending away from the ground, which are used to limit the connection with the driven wheel to prevent the track from derailing (i.e., the chain falls off). As can be seen from the figure, the spacing of the guide teeth 102 is adapted to the tire width of the driven wheel, which is similar to the traditional guide tooth 102 structure.
[0055] In this embodiment, to provide better grip and off-road capability, the axial end face of the track tooth body 100 is rectangular or triangular. (Reference) Figure 17 The rectangular track tooth body 100 has a simple, pre-machined structure, resulting in less wear and tear on hard surfaces. However, due to its rectangular shape, it is best to incorporate multiple radially arranged reinforcing ribs inside to improve its overall support strength and prevent flattening deformation.
[0056] refer to Figure 16Due to its triangular shape, the track tooth body 100 has higher support strength and is more durable, and can also be reinforced with ribs. With this shape, the included angle of the track tooth body 100 towards the ground is rounded, thus preventing significant damage to hard surfaces.
[0057] To achieve better stability, skirt portions 103 are provided on both sides of the track tooth body 100 in the axial direction, symmetrically arranged on both sides of the track tooth body 100 in the axial direction, and a plurality of connecting holes 101 are placed on the skirt portions 103. This structure ensures that the connecting holes 101 are located on both sides of the track tooth body 100 in the axial direction, rather than directly penetrating the track tooth body 100, making the track tooth body 100 more complete and integral.
[0058] refer to Figure 15 To facilitate the disassembly of the connector 104, a through hole 106 can be provided on the ground-facing side of the track tooth body 100 for easy installation of the connector 104. However, the through hole 106 can be omitted. For example, a nut can be directly fixed inside the track tooth body 100, or a threaded bolt can be used at the other end (e.g.,...). Figure 16 and Figure 17 (As shown).
[0059] This structure relocates the connecting holes 101 in the radial direction of the original track tooth body 100 to the skirt portion 103, making the track tooth body 100 more complete and integrated. In addition, connecting holes 101 are provided on both sides of the track tooth body 100, increasing the number and providing more fixed connection points between the track tooth body 100 and the track 200 (see reference). Figures 5 to 10 The connection between the two is more robust, making operation more stable and reliable in harsh environments.
[0060] As a further improvement of this utility model, the edge of the skirt portion 103 has a rounded corner structure. This structure is designed because in harsh outdoor working environments, the edges of metal parts can easily generate hard friction with the rubber track, accelerating the wear of the rubber track. This structure allows for smoother contact between the two, preventing premature damage to the rubber connection.
[0061] In addition, since the track makes frictional contact with the ground when turning, especially when turning on hard surfaces, the axial ends of the track tooth body 100 are in a state of hard friction with the ground. In order to achieve better and smoother turning, and to prevent scratching the ground, the axial ends of the track tooth body 100 are rounded. This way, the friction between the axial ends of the track tooth body 100 and the ground will be smoother when turning.
[0062] With the above structure, the track tooth structure in this embodiment is more reasonable, with better grip and extrication performance in muddy and swampy areas. It also allows for individual disassembly and replacement of each track tooth, which greatly extends the overall service life of the track and reduces replacement costs. This is a significant advantage compared to traditional one-piece tracks.
[0063] Example 2
[0064] The similarities between this embodiment and Embodiment 1 will not be repeated here.
[0065] Reference Figures 11 to 14 The purpose of this embodiment is to provide a track that combines the robustness and durability of a metal track with the toughness of rubber, while being lightweight and low-cost. Of course, metal wires also need to be incorporated into the rubber track to improve its durability.
[0066] Specifically, it includes a rubber track 200, on the side of the rubber track 200 facing the ground, a plurality of track teeth are evenly arranged along its width. The track teeth and the rubber track 200 are fastened together by a connector 104 (such as a fastening bolt) passing through the connection hole 101. The track teeth are made of metal, and the track is made of rubber. The combination of the two gives the track not only the strength of a metal track, but also the advantages of rubber tracks such as low cost and light weight. Importantly, the metal track tooth body 100 can be replaced separately from the rubber track 200, and even when stuck outdoors, the connector 104 can be easily removed for replacement.
[0067] Secondly, even if the rubber track 200 is partially damaged or torn, it can be cut and joined end to end, then connected to the track tooth body 100 via connector 104. This significantly reduces maintenance costs, eliminating the need to replace the entire track, resulting in substantial cost savings and greater portability. The rubber track can be made to any length as needed, with the ends simply joined and secured. For example, if one or more sections of the track are damaged, that section can be cut off individually, and a new track section can be used to fill the gap. The ends are also connected using connector 104, allowing the original track to continue to be used. In other words, the entire track can be repaired in a multi-segment, end-to-end connection manner, maximizing cost reduction.
[0068] In this embodiment, to achieve a better and more stable connection, the side of the rubber track 200 away from the track tooth body 100 is provided with a pad 105 that is securely connected to the connector 104. This pad can be a strip or a single washer. Of course, a strip-shaped pad 105 is preferable, as it provides a better and more complete connection.
[0069] As a further improvement of this utility model, the side of the skirt portion 103 away from the track tooth body 100 is inclined toward the rubber track 200.
[0070] The reason for adopting the above structure is that the track tooth body 100 will turn and change direction at the drive wheel 301, and the rubber track 200 will bend, causing a gap to appear between the rubber track 200 and the skirt part 103. The two are no longer completely in contact, so mud will seep in, which will accelerate the aging and damage of the parts over time.
[0071] Furthermore, the rubber track 200 can also bend and pull. When the skirt 103 is tilted, it will have a certain curvature, which can better fit with the rubber track 200 when turning or changing direction. It is difficult for foreign objects such as mud to enter, and it also prevents the two from being excessively torn at this position, prevents the connecting hole 101 from being excessively deformed and damaged, and extends the service life of the rubber track 200.
[0072] By adopting the above structure, this embodiment achieves the combination of rubber track and metal track teeth, which not only has the advantages of the toughness and low cost of rubber track, but also the advantage of replacing track teeth individually to reduce costs, and is convenient to use and maintain while reducing weight.
[0073] Example 3
[0074] The similarities between this embodiment and Embodiment 2 will not be repeated here.
[0075] The purpose of this embodiment is to provide a tracked vehicle (such as...) Figure 18 As shown, the vehicle body 300 is provided with a drive wheel 301 and a number of driven wheels 302 on both sides of the vehicle body 300. Compared with traditional tracked vehicles, this embodiment does not require a tensioning wheel.
[0076] The drive wheel 301 is provided with equally spaced drive teeth 3011. The tooth groove 3012 between each two adjacent drive teeth 3011 meshes with the aforementioned guide teeth 102 for transmission. That is, the guide teeth 102 not only serve to limit the connection with the driven wheel 302, but also play a role in meshing and transmitting power with the drive wheel 301. The two sides of the driven wheel 302 are clamped by the guide teeth 102, so that the rubber track 200 will not derail on rough muddy roads, ensuring stable and reliable driving.
[0077] Traditional tracked vehicles are equipped with tension rollers to keep the tracks taut, which is essential for driving. Therefore, the tension rollers must be removed before disassembly or reassembly, making the process very inconvenient.
[0078] The rubber track of this structure is fastened at both ends by connectors 104. Disassembling the track only requires removing connectors 104 (i.e., fastening bolts), a very convenient process that can be done manually even outdoors. Secondly, the track itself needs to be taut before being fastened, ensuring tension after connection. Furthermore, the driven wheels 302 are held in place by guide teeth 102 on both sides, and with the drive connection of the drive wheel 301, the track maintains stable operation during rotation, limiting both its travel and lateral movement. Even during turning, the guide teeth 102 remain firmly engaged with the driven wheels to prevent derailment (e.g., ...). Figure 15 It serves as a limiting support from the side.
[0079] As a further improvement of this utility model, the guide tooth 102 has an inclined surface structure on the side facing the driven wheel 302. This structure serves two purposes: firstly, to facilitate smooth clamping with the driven wheel, and secondly, to achieve a gradual clamping effect with the driven wheel profile. Of course, the spacing of the guide tooth 102 needs to be adapted to the driven wheel 302, ensuring not only smooth clamping but also a firm clamping force. Especially when the driven wheel is under pressure (such as when fully loaded with goods) and its sides bulge, it can more firmly and snugly clamp with the guide tooth 102. That is, the greater the vehicle load, the more stable the clamping between the driven wheel and the guide tooth 102, and the better the operational stability (such as during steering). As the driven wheel rotates, the inclined surface structure also facilitates quick and smooth disengagement from the guide tooth 102.
[0080] As a further improvement of this invention, the driven wheel 302 is a rubber wheel, which can further reduce the vehicle's weight, while the driven wheels of traditional tracked vehicles are all metal wheels. In addition to this effect, the rubber wheel also significantly reduces operating and maintenance costs, and its service life is greatly extended; it can be replaced and maintained at ordinary auto repair shops. Moreover, the rubber wheel also provides excellent cushioning, reducing vibrations felt on bumpy roads and increasing ride comfort. Traditional metal tracked vehicles, on the other hand, experience very noticeable bumps; even small stones on the road can cause significant jolting.
[0081] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:
[0082] By adopting the track teeth and tracks described in this application, tracked vehicles no longer require a tensioner, making disassembly and maintenance much more convenient. A stable transmission relationship can be achieved between the tracks and the drive and driven wheels, simplifying the vehicle's structure and making on-site track replacement or maintenance easier and faster. Furthermore, the vehicle's weight is significantly reduced, making it less prone to getting stuck, and more power can be distributed to other drive components, resulting in higher operational efficiency.
[0083] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
