Description

Technical Field

[0001] This utility model relates to the field of snow track technology, and in particular to a snowmobile anti-sinking track. Background Technology

[0002] Tracks are the driving component of snowmobiles. Especially in loose powder snow with poor compressibility, tracks significantly reduce the pressure exerted by the vehicle on the snow by distributing the engine's power and the weight of the vehicle onto a large contact surface. The engine transmits power to the drive wheel at the rear of the track via a gearbox and chain or belt. The teeth on the drive wheel engage with the holes in the track plates, causing the entire track to rotate around the skid wheel under the chassis. The track plates typically have raised patterns that deeply "bite" into the snow, providing tremendous traction and enabling snowmobiles to climb hills, travel on rough terrain, and effectively prevent slippage.

[0003] The publication number CN219428255U, entitled "A Widened Anti-Sinking Rubber Track," mentions that rubber tracks have limited width and often get stuck and cannot move. Simply increasing the original track width is insufficient because the steel plates inside the track have limited width and cannot support an excessively wide track. By setting up an anti-sinking bar that can be installed and removed, the ease of use of the anti-sinking bar is improved, as well as the anti-sinking effect is enhanced.

[0004] However, while the aforementioned patents achieve the anti-sinking effect, the installation and disassembly structures are relatively complex. In harsh environments, impurities can easily become stuck at the connection point. Snowmobile tracks often need to move through loose powder snow, and if the aforementioned structure is used, impurities can also easily become stuck at the installation and disassembly points. Based on this, an improvement is proposed. Utility Model Content

[0005] In view of the problems mentioned above, the technical problem to be solved by this utility model is to provide a snowmobile anti-sinking track.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a snowmobile anti-sinking track, comprising multiple integrated track bodies, an inner side of the track body having an integral meshing tooth that cooperates with the snowmobile drive wheel, an inner side of the track body also having an meshing port that cooperates with the snowmobile drive wheel, an outer side of the track body having an integral track plate, a transversely integral protruding shaft portion of the track body, an extension axis of the protruding shaft portion having a through-hole for installation, and a support shaft for support within the installation channel; The mounting channel on the outer side of the protruding shaft end forms a cavity, and the two ends of the protruding shaft are also provided with inwardly extending slots. Mounting part one or mounting part two can be selectively installed in the cavity and slots. Mounting part one is used to seal the cavity, and mounting part two includes a reinforcing plate to increase the contact area with the snow.

[0007] A further preferred embodiment of this utility model is: the track plate is integrally located on the outside of the protruding shaft, and the track plate is a sheet extending outward.

[0008] A further preferred embodiment of this utility model is: the thickness of the track plate gradually decreases along the outward extension direction, and both sides of the track plate are integrally provided with reinforcing ribs, the thickness of which gradually narrows along the outward extension direction of the track plate.

[0009] A further preferred embodiment of this utility model is: the lower end face of the track body has a pattern for increasing friction with the snow.

[0010] A further preferred embodiment of this utility model is as follows: the support shaft has multiple threaded holes, the threaded holes closest to both ends of the support shaft pass through the slots on both sides respectively, and the track body has a number of fastening bolts corresponding to the number of threaded holes and threadedly connected to the threaded holes on the inward side, which are used to limit the support shaft.

[0011] A further preferred embodiment of this utility model is: the mounting part includes a support plate and a threaded cover; A retaining hole is through the support plate, which is embedded in the retaining groove. The retaining hole engages with the outermost threaded hole. The threaded cap is threadedly connected inside the cavity to seal the cavity.

[0012] A further preferred embodiment of this utility model is: the outer side of the threaded cover has a force-receiving groove for driving the threaded cover to rotate.

[0013] A further preferred embodiment of this utility model is: the mounting part two also includes a circular end and a support plate two; The second support plate extends into the reinforcing plate and is fixed to the reinforcing plate. The second support plate is embedded in the slot. The second support plate has a second locking hole that mates with the corresponding threaded hole. The second support plate is limited by fastening bolts that pass through the corresponding threaded hole and the second locking hole.

[0014] A further preferred embodiment of this utility model is: a circular end is sleeved on the second support plate near the reinforcing plate, and the circular end is made of rubber to block into the cavity.

[0015] A further preferred embodiment of this utility model is that the reinforcing plate is made of the same material as the track body, which is rubber.

[0016] Compared with the prior art, the advantages of this utility model are: 1. Both mounting parts 1 and 2 can be connected to the track body. Mounting part 1 is used to seal the connection position, and mounting part 2 is used to widen it. Its structure is simple and prevents impurities such as powder, snow, mud and water from entering the core connection part, ensuring long-term reliability and smooth operation in icy and snowy environments. Both mounting parts 1 and 2 are embedded into the slot and locked by fastening bolts, which minimizes the number of parts and makes them less prone to damage.

[0017] 2. The support shaft is used to support the track body, increasing the strength of the track body and making the support shaft act as a skeleton. When the mounting part 2 cooperates with the support shaft, the support plate 2 is directly embedded and fixed on the support shaft that bears the main load, so that the support shaft and support plate 2 bear the main force, achieving widening without losing support.

[0018] 3. The second mounting part for widening can be disassembled. For example, when driving on compacted snow tracks, narrow forest trails, or when performing skillful driving, the first mounting part can be quickly replaced to restore the standard width. When the support plate in the first mounting part is embedded in the slot, the support shaft does not have a cavity and is not easily deformed. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes a snowmobile anti-sinking track. Please refer to [link / reference]. Figures 1-7 Specifically, as follows: Although there are already anti-sinking tracks, their installation and disassembly structures are relatively complex. In harsh environments, impurities can easily get stuck at the connection point. Snowmobile tracks often need to move in loose powder snow. If the above structure is used, impurities can also easily get stuck at the installation and disassembly points. Based on this, an anti-sinking track for snowmobiles is proposed, including a multi-section integrated track body 1. The track body 1 has an integrated meshing tooth 3 on the inner side that cooperates with the snowmobile drive wheel. The track body 1 also has a meshing port 2 on the inner side that cooperates with the snowmobile drive wheel. The track body 1 has an integrated track plate 5 on the outer side. The track body 1 has a protruding shaft 4 on the lateral side. The extended axis of the protruding shaft 4 passes through an installation channel 7. The installation channel 7 has a support shaft 8 for support. The outer part of the mounting channel 7 at the end of the protruding shaft 4 forms a cavity 71, and the two ends of the protruding shaft 4 are also provided with inwardly extending slots 82. The cavity 71 and the slots 82 can be optionally equipped with mounting part 1 9 or mounting part 2 10. Mounting part 1 9 is used to seal cavity 71, and mounting part 2 10 includes reinforcing plate 101 to increase the contact area with snow.

[0025] Specifically, the track body 1 and its meshing mouth 2 and meshing teeth 3 are all existing technologies. The track plate 5 is also a conventional existing technology to enable the track body 1 to travel on snow. However, when the snowmobile is moving in loose powder snow, if the snowmobile is relatively heavy, the track body 1 is prone to sinking into the snow, which can lead to difficulty in navigation and increased fuel consumption. By installing the mounting part 2 10 on the outside of the track body 1, the track body 1 can be widened so that it can move on loose powder snow. Furthermore, if it is not suitable to widen the track, the mounting part 2 10 can be removed and the mounting part 1 9 can be installed to restore the width of the track body 1.

[0026] like Figure 2 As shown, the track plate 5 is integrally located on the outside of the protruding shaft portion 4, and the track plate 5 is a sheet extending outward.

[0027] Specifically, when the track body 1 is traveling, the track plate 5 needs to engage with the snow surface and push the snow, so the track plate 5 needs to be extended in a sheet shape.

[0028] like Figure 2 As shown, the thickness of the track plate 5 gradually decreases along the outward extension direction, and both sides of the track plate 5 are integrally provided with reinforcing ribs 51, the thickness of the reinforcing ribs 51 gradually narrows along the outward extension direction of the track plate 5.

[0029] Specifically, the reinforcing rib 51 is used to support the track plate 5, so that the track plate 5 does not bend when pushing the snow. Secondly, the thickness of the track plate 5 gradually decreases along the outward extension direction, so that the outer end of the track plate 5 is relatively narrow and can be smoothly inserted into the snow.

[0030] like Figure 2 As shown, the lower end face of the track body 1 has a pattern 6 for increasing friction with the snow. The pattern 6 can engage with the snow surface to increase friction.

[0031] like Figure 3 and Figure 5 As shown, the support shaft 8 has multiple threaded holes 81. The threaded holes 81 closest to both ends of the support shaft 8 pass through the slots 82 on both sides. The track body 1 has a number of fastening bolts 83 corresponding to the number of threaded holes 81 and threadedly connected to the threaded holes 81 on the inward side, which are used to limit the support shaft 8.

[0032] Specifically, the support shaft 8 is used to increase the strength of the track body 1. The support shaft 8 is fixed to the track body 1 through the threaded hole 81 and the fastening bolt 83, and will not detach during use.

[0033] like Figures 4-5 As shown, the mounting part 9 includes a support plate 91 and a threaded cover 93; A locking hole 92 is passed through the support plate 91. The support plate 91 is embedded in the locking groove 82, and the locking hole 92 is engaged with the outermost threaded hole 81. The threaded cover 93 is threadedly connected in the cavity 71 to close the cavity 71.

[0034] Specifically, the function of the mounting section 9 is to seal the cavity 71 and fill the slot 82, so that the support shaft 8 is solid and not easily deformed under external pressure, thus maintaining a stable support function.

[0035] like Figure 4 As shown, the outer side of the threaded cap 93 has a force-receiving groove 931 for driving the threaded cap 93 to rotate. Specifically, the threaded cap 93 can be installed or removed by using an external device such as a screwdriver, which is extended into the force-receiving groove 931 and rotated.

[0036] like Figures 6-7 As shown, the mounting part 2 10 also includes a circular end 102 and a support plate 2 103; The second support plate 103 extends into the reinforcing plate 101 and is fixed to the reinforcing plate 101. The second support plate 103 is embedded in the slot 82. The second support plate 103 has a slot 104 that mates with the corresponding threaded hole 81. The second support plate 103 is limited by fastening bolts 83 passing through the corresponding threaded hole 81 and slot 104.

[0037] Specifically, the reinforcing plate 101 is secured within the slot 82 by the support plate 2 103 and fixed with bolts, ensuring that the position of the reinforcing plate 101 remains unchanged. Furthermore, since the support plate 2 103 is clamped within the slot 82, the reinforcing plate 101 can directly bear the weight of the snowmobile during use, relatively increasing the contact area between the tracks and the snow, making the snowmobile less prone to sinking. It should be noted that the support plate 2 103 has a corresponding locking hole 2 104 that aligns with the threaded hole 81; therefore, when the fastening bolt 83 is tightened, the support plate 2 103 is also positioned within the locking range.

[0038] like Figure 7 As shown, a circular end 102 is fitted onto the support plate 103 near the reinforcing plate 101. The circular end 102 is made of rubber and is used to block the cavity 71. The circular end 102 limits the cavity 71, keeping it in a closed state and preventing external impurities from moving inward.

[0039] The reinforcing plate 101 is made of the same material as the track body 1, which is rubber. When the track body 1 is in operation, such as... Figure 1As shown, a ring structure is formed, and the part that contacts the snowmobile drive wheel also needs to be bent to contact the drive wheel. Therefore, the rubber material can deform. It should be noted that, due to the connection of the support plate 2 103, the reinforcing plate 101 can also achieve the same changes as the track body 1.

[0040] Working principle: such as Figures 1-3 As shown, the engine transmits power to the drive wheel at the rear of the track body 1 through the gearbox and chain or belt. The drive wheel drives the track body 1 to run. It should be noted that the drive wheel can mesh with the meshing port 2 or meshing tooth 3 on the track body 1, so that the drive wheel drives the track body 1 to drive the transmission when it rotates.

[0041] The track plates 5 and reinforcing ribs 51 allow the track body 1 to deeply "bite" into the snow, providing tremendous grip and enabling the snowmobile to climb slopes, travel on rugged terrain, and effectively prevent slippage. Secondly, since both the track plates 5 and reinforcing ribs 51 are tapered, their tips can easily penetrate hard snow, firmly gripping the ground and efficiently converting engine power into forward thrust. The reinforcing ribs 51 maintain the rigidity of the track plates 5, preventing them from bending. In addition, the protruding axle 4 provides a reaction force when the track plates 5 engage with hard snow, attempting to "bend" or even "tear" the track plates 5 off the track body 1. The protruding axle 4 greatly increases the connection area and structural strength between the track plates 5 and the track body 1.

[0042] Furthermore, the structural strength of the track body 1 is further improved by the support shaft 8 inside the protruding shaft part 4, making it less likely to deform when subjected to snow and snowmobile pressure.

[0043] With the installation part 9, the support plate 91 is embedded in the slot 82 at the end of the support shaft 8, so that the slots 82 at both ends of the support shaft 8 are closed. Therefore, even under external pressure, the support shaft 8 is not easily deformed. Secondly, since it is located in the snow, the cavity 71 is closed by the threaded cover 93 to prevent rain, snow and impurities from entering the installation channel 7 as much as possible. After removing mounting part 19, the support plate 2 103 of mounting part 2 10 can be engaged with the slot 82 at the end of the support shaft 8, thus sealing the slots 82 at both ends of the support shaft 8 and preventing deformation. The round end 102 is then inserted into the cavity 71, sealing the mounting channel 7 and preventing rain, snow, and impurities from entering it. It should be noted that the reinforcing plate 101 increases the support area of ​​the snowmobile, preventing the track body 1 from sinking into the snow and allowing it to move in loose powder snow. Additionally, it should be noted that due to environmental limitations, wider tracks are not always convenient; therefore, mounting part 2 10 can be disassembled and replaced with mounting part 1 9 to maintain the snowmobile's maneuverability.

[0044] It should also be noted that the reinforcing plate 101 in the second mounting section 10 is spliced ​​with the support shaft 8 through the second support plate 103, so that the reinforcing plate 101 and the track body 1 can both bear the weight of the snowmobile. It should also be noted that the support plate 91 or the second support plate 103 can be fastened to the support shaft 8 by the fastening bolts 83, which is easy to install while ensuring a certain strength.
