Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber track technology, and in particular to a lateral auxiliary transmission type rubber track. Background Technology
[0002] In the field of rubber track technology, rubber tracks are widely used in various mobile equipment such as construction machinery and agricultural machinery due to their advantages of strong adaptability to ground conditions and minimal damage to road surfaces. As the core mobile component of construction machinery and other equipment, the track's transmission stability, load-bearing capacity, and steering flexibility directly determine the equipment's operating efficiency and adaptability. Existing rubber tracks mostly adopt a single main drive structure, that is, the track is driven to move in a cyclical motion by meshing a single main drive wheel with the inner wall of the track to achieve the movement of the equipment.
[0003] However, such traditional transmission structures have obvious shortcomings in practical applications: the meshing contact area between a single main drive wheel and the track is limited. When the equipment operates in complex road conditions (such as muddy or rugged roads) or carries a heavy load, the track is prone to slippage and tooth skipping due to excessive local stress, resulting in a decrease in transmission efficiency and even accelerated wear of the inner interlocking structure of the track, shortening the service life of the track. At the same time, the traditional track is subjected to uneven force on both sides during turning, which can easily cause tearing and deformation of the track edges. Especially for large equipment, the stability and safety during turning are difficult to guarantee. Therefore, this application proposes a side-assisted transmission type rubber track. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lateral auxiliary transmission type rubber track to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lateral auxiliary transmission type rubber track, comprising: The tracks are made of rubber and produced through a vulcanization process, and the tracks are designed in an elliptical ring shape. The main insert is provided in several parts and is equidistantly distributed at the center of its inner wall along the direction of the track; The secondary blocks are provided in two sets. Both sets of secondary blocks are set on the inner wall of the track and are symmetrically distributed on both sides of the main block. Each set of secondary blocks has several blocks and is equidistantly distributed on its inner wall along the direction of the track. There are two main drive wheels, located at both ends between the tracks. Both main drive wheels are engaged with the main inserts on the inner wall of the tracks. Auxiliary drive wheels are provided on both sides of the two main drive wheels. The transmission belt is provided in two sets and is respectively fitted between two auxiliary transmission pulleys on the same side, and the two transmission belts are respectively engaged with two sets of auxiliary blocks on the inner wall of the track. The connecting components are provided in two sets, which are respectively inserted between the two main drive wheels and the corresponding auxiliary drive wheels.
[0006] Optionally, an insertion hole is provided at the shaft center of the main drive wheel, and four limiting plates are distributed in a circular array on the inner wall of the insertion hole. Fixing blocks are installed at the shaft center on both sides of the main drive wheel and on both sides of the insertion hole. Multiple main insert grooves that mesh with the main insert blocks are evenly provided on the outer wall of the main drive wheel.
[0007] Optionally, the auxiliary drive wheel includes a connecting plate, an outer ring, and teeth. The connecting plate is circular and coaxially arranged with the main drive wheel. The outer ring is coaxially sleeved on the outside of the connecting plate. Multiple reinforcing rods are evenly connected between the inner wall of the outer ring and the connecting plate. Several teeth are provided and distributed in a circular array on the outer wall of the outer ring. Four fan-shaped openings are provided at the center of the connecting plate, and the four openings are distributed in a circular array.
[0008] Optionally, the connecting assembly includes a shaft and retaining rings. The shaft is inserted through a hole at the center of the main drive wheel shaft, and four limiting grooves that fit the limiting plate are evenly opened on the surface of the shaft. Two screw holes are opened on the outer wall of the shaft at the position of the fixing block. First bolts are inserted through between the two screw holes and the corresponding two fixing blocks. Cross grooves are opened at both ends of the shaft. Four through holes on the connecting plate of the secondary drive wheel are fitted into the cross grooves at the ends of the shaft. Two sets of retaining rings are provided and are threaded onto both ends of the shaft. The two retaining rings abut against the outer side of the connecting plate of the corresponding secondary drive wheel. Four second bolts that connect to the corresponding connecting plate are inserted through the sides of the two retaining rings.
[0009] Optionally, the surface of the transmission belt is evenly provided with several external grooves from the outside to the inside, and the external grooves are engaged with the auxiliary inserts on the inner wall of the track. The surface of the transmission belt is evenly provided with several internal grooves from the inside to the outside, and the number of internal grooves is the same as the number of external grooves. The internal grooves and external grooves are distributed in an alternating manner. The teeth on the outer ring of the auxiliary drive wheel are engaged with the internal grooves on the track.
[0010] Optionally, the outer surface of the track is evenly provided with several trapezoidal teeth, and reinforcing strips are provided on both sides of the track.
[0011] The beneficial effects of this utility model are: The main drive wheel meshes with the main insert in the center of the inner wall of the track, while the auxiliary drive wheels on both sides mesh with the auxiliary inserts in the inner wall of the track through the drive belt. This greatly increases the meshing contact area between the track and the transmission components. In complex road conditions (such as muddy or rugged roads) or when carrying heavy loads, it disperses the local force on the track, effectively avoiding track slippage and tooth skipping caused by excessive local pressure, ensuring stable transmission efficiency and reducing the risk of equipment operation interruption.
[0012] Through the coordinated meshing of the main insert, the secondary insert, and the corresponding transmission components, the driving force is evenly transmitted to the entire track, avoiding excessive stress on the local interlocking structure. At the same time, the rubber track is made through a vulcanization process, which has good wear resistance. Combined with the evenly distributed transmission method, the wear on the inner interlocking structure and edges of the track is further reduced, significantly extending the service life of the track.
[0013] The auxiliary drive wheels on both sides of the main drive wheel make the force on both sides of the track more balanced during the turning process, avoiding excessive pressure on one side of the track. At the same time, the reinforcing strips on both sides of the track further enhance the structural strength of the track edge, effectively preventing the track edge from tearing and deforming during turning, ensuring the stability and safety of the equipment during the turning process, and reducing equipment maintenance costs.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] Please see Figures 1-7 This utility model provides a technical solution: a lateral auxiliary transmission type rubber track, including a track 1, which is made of rubber and vulcanized. The track 1 is elliptical and ring-shaped. Several main inserts 12 are equidistantly distributed at the center of their inner wall along the direction of the track 1. Two sets of auxiliary inserts 13 are provided, each set located on the inner wall of the track 1 and symmetrically distributed on both sides of the main inserts 12. Each set of auxiliary inserts 13 has several blocks equidistantly distributed on its inner wall along the direction of the track 1. Two main drive wheels 2 are provided, located at opposite ends of the track 1, and both main drive wheels 2 are engaged with the main inserts 12 on the inner wall of the track 1. Auxiliary drive wheels 3 are provided on both sides of the two main drive wheels 2. Two sets of drive belts 4 are provided, each fitted between the two auxiliary drive wheels 3 on the same side, and the two drive belts 4 are engaged with the two sets of auxiliary inserts 13 on the inner wall of the track 1. The connecting and connecting components 5 are provided in two sets and are respectively inserted between the two main drive wheels 2 and the corresponding auxiliary drive wheels 3. Through the combination of the main drive structure of "main drive wheel 2 + main insert 12" and the auxiliary drive structure of "auxiliary drive wheel 3 + drive belt 4 + auxiliary insert" 13, the traditional single main drive mode is broken. The symmetrical distribution of the main insert 12 and auxiliary insert 13 on the inner wall of the track 1, together with the synergistic effect of the two sets of auxiliary drive wheels 3 and drive belt 4, greatly increases the meshing contact area between the track 1 and the transmission components. It can not only disperse the local force on the track 1 under complex road conditions (such as muddy and rugged roads) or heavy load scenarios, avoid slippage and tooth skipping problems, and ensure stable transmission efficiency, but also reduce the wear of the inner meshing structure of the track 1 through balanced driving force transmission. At the same time, in conjunction with the elliptical ring track 1 made of rubber material vulcanization process, the overall durability of the track 1 is improved, laying the foundation for the subsequent functional optimization of various components.
[0017] like Figure 4 and Figure 5As shown, an insertion hole 22 is provided at the shaft center of the main drive wheel 2. Four limiting plates are distributed in a circular array on the inner wall of the insertion hole 22. Fixing blocks 23 are installed at the shaft center on both sides of the main drive wheel 2 and on both sides of the insertion hole 22. Multiple main insert grooves 21 that mesh with the main insert block 12 are evenly provided on the outer wall of the main drive wheel 2. By opening the insertion hole 22 with four limiting plates at the shaft center and setting the fixing blocks 23 on both sides, on the one hand, it provides a precise positioning and installation foundation for the shaft 51 of the subsequent connecting component 5, ensuring the coaxiality and stability of the shaft 51 when connected to the main drive wheel 2, and avoiding transmission deviation caused by component misalignment during transmission; on the other hand, the main insert grooves 21 evenly provided on the outer wall of the main drive wheel 2 precisely mesh with the main insert block 12 on the inner wall of the track 1, further optimizing the transmission adaptability of the main drive structure and enhancing the biting force during the main drive process.
[0018] like Figure 4 and Figure 6 As shown, the auxiliary drive wheel 3 includes a connecting plate 31, an outer ring 33, and teeth 34. The connecting plate 31 is circular and coaxially arranged with the main drive wheel 2. The outer ring 33 is coaxially sleeved on the outside of the connecting plate 31. Multiple reinforcing rods 32 are evenly connected between the inner wall of the outer ring 33 and the connecting plate 31. Several teeth 34 are arranged in a circular array on the outer wall of the outer ring 33. Four fan-shaped openings 35 are opened at the center of the connecting plate 31, and the four openings 35 are arranged in a circular array. The connecting plate 31 is coaxially arranged with the main drive wheel 2 to ensure that the auxiliary drive wheel 3 is connected to the main drive wheel. The transmission synchronization of 2; the multiple reinforcing rods 32 between the outer ring 33 and the connecting plate 31 effectively enhance the structural strength of the auxiliary transmission wheel 3, prevent the auxiliary transmission wheel 3 from deforming under long-term transmission force, and improve its load resistance; the teeth 34 on the outer wall of the outer ring 33 provide a matching structure for subsequent meshing with the embedded groove 41 on the surface of the transmission belt 4, ensuring stable transmission between the auxiliary transmission wheel 3 and the transmission belt 4; the four fan-shaped through-holes 35 in the center of the connecting plate 31 provide space for the installation of the cross groove 55 at the end of the shaft 51, realizing the precise docking of the auxiliary transmission wheel 3 and the connecting component 5.
[0019] like Figure 4 , Figure 5 and Figure 6As shown, the connecting assembly 5 includes a shaft 51 and retaining rings 56. The shaft 51 is inserted through the insertion hole 22 at the shaft center of the main drive wheel 2, and four limiting grooves 52 adapted to the limiting plate are evenly opened on the surface of the shaft 51. Two screw holes 53 are opened on the outer wall of the shaft 51 at the position of the fixing block 23. First bolts 54 are inserted through the two screw holes 53 and the corresponding two fixing blocks 23. Cross grooves 55 are opened at both ends of the shaft 51. The four through holes 35 on the connecting plate 31 of the auxiliary drive wheel 3 are fitted into the cross grooves 55 at the ends of the shaft 51. Two sets of retaining rings 56 are provided and are threaded onto both ends of the shaft 51. The two retaining rings 56 abut against the outer side of the connecting plate 31 of the corresponding auxiliary drive wheel 3. Four second bolts 56 connected to the corresponding connecting plate 31 are inserted through the sides of the two retaining rings 56. 7. The limiting groove 52 on the surface of the shaft 51 is adapted to the limiting plate in the insertion hole 22. The shaft 51 is connected to the fixing block 23 with the first bolt 54. The double fixing method ensures the firmness of the connection between the shaft 51 and the main drive wheel 2 and prevents the shaft 51 from loosening during transmission. The cross grooves 55 at both ends of the shaft 51 are matched with the fan-shaped through-holes 35 of the connecting plate 31 in the auxiliary drive wheel 3 to achieve precise positioning of the auxiliary drive wheel 3 and the shaft 51 and ensure transmission synchronization. The retaining ring 56 is threaded onto both ends of the shaft 51 and abuts against the connecting plate 31. It is then further fixed by the second bolt 57. This not only prevents the auxiliary drive wheel 3 from moving in the axial direction, but also facilitates the disassembly and maintenance of subsequent components. The overall connection structure design takes into account both connection stability and maintenance convenience, ensuring the coordinated transmission of the main drive wheel 2 and the auxiliary drive wheel 3 and improving the reliability of the entire transmission system.
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the surface of the transmission belt 4 is evenly provided with several outer grooves 42 from the outside to the inside. The outer grooves 42 are engaged with the auxiliary inserts 13 on the inner wall of the track 1. The surface of the transmission belt 4 is evenly provided with several inner grooves 41 from the inside to the outside. The number of inner grooves 41 is the same as the number of outer grooves 42, and the inner grooves 41 and outer grooves 42 are distributed in an alternating manner. The teeth 34 on the outer ring 33 of the auxiliary drive wheel 3 are engaged with the inner grooves 41 on the track 1. By providing grooves 42 on the surface of the transmission belt 4, the transmission belt 4 is equipped with several inner grooves 41. The outer groove 42 and the inner groove 41 are staggered and of the same number, forming a "two-way meshing" adaptation structure. The outer groove 42 meshes precisely with the auxiliary insert 13 on the inner wall of the track 1, ensuring that the transmission belt 4 can stably transmit auxiliary driving force to the track 1. The inner groove 41 meshes with the teeth 34, ensuring that the auxiliary drive wheel 3 can efficiently drive the transmission belt 4. The two-way meshing design greatly improves the transmission stability between the transmission belt 4, the auxiliary drive wheel 3, and the track 1, and reduces slippage during transmission.
[0021] like Figure 1 and Figure 2As shown, the outer surface of the track 1 is uniformly provided with several trapezoidal teeth 11, which can significantly enhance the friction and grip between the track 1 and the ground. Especially in complex road conditions such as mud and soft ground, it can effectively prevent the track 1 from slipping and improve the stability and passability of the equipment. Reinforcing strips 14 are provided on both sides of the track 1, which directly enhances the structural strength of the track 1 edge, solves the problem of edge tearing and deformation caused by uneven force on both sides during the turning process of traditional track 1, extends the overall service life of track 1, and further improves the structural durability and turning safety of track 1 while having good ground adaptability.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
