Description

Technical Field

[0001] This utility model relates to the field of track technology, and in particular to a novel rubber track. Background Technology

[0002] Rubber tracks are widely used in engineering machinery, agricultural machinery, and special vehicles, and their performance directly affects the equipment's passability, stability, and lifespan.

[0003] However, existing technologies still have many shortcomings: traditional rubber substrates and track bodies mostly rely on single vulcanization or adhesive bonding, which are prone to peeling and falling off under alternating stress and harsh working conditions; the design of the rubber surface teeth often results in insufficient grip and severe stress concentration due to sharp tooth shape and abrupt transitions, making it easy to slip and break in muddy or soft terrain; the arrangement of drive wheels, support rollers and driven wheels lacks optimization, and problems such as uneven number of rollers and non-parallel axes exacerbate uneven stress on the track, causing vibration and localized wear; the drive tooth roots and rubber teeth of the track body are mostly right angles or acute angle transitions, resulting in significant stress concentration and accelerating fatigue fracture and cracking; some track bodies adopt an integral structure, or the strength and flexibility of the chain link connection are difficult to balance, making it unable to adapt to the bending and deformation requirements of complex terrain.

[0004] The aforementioned problems restrict the reliability, performance, and lifespan of rubber tracks, and a systematic breakthrough through innovative design is urgently needed. Utility Model Content

[0005] This invention provides a novel rubber track to overcome the shortcomings of existing technologies.

[0006] This utility model provides a novel rubber track, including a track body, which is internally provided with a drive wheel, a support roller, and a driven wheel.

The inner side of the track body is provided with a roller support part, which consists of convex strips that are adapted to the outer periphery of the support roller and are evenly distributed along the circumference of the track. The track body has driven wheel connecting parts at both ends, which are in contact with the outer wall of the driven wheel; The track body is covered with a rubber matrix, and the track body is formed by several chain links that are sequentially hinged together by pins to form a closed loop.

[0007] According to the present invention, a novel rubber track is provided, wherein the number of supporting rollers is 3-5, which are evenly distributed at equal intervals along the circumference of the track body; the axes of the drive wheel, the supporting rollers and the driven wheel are parallel to each other.

[0008] According to the present invention, a novel rubber track is provided, wherein the rubber matrix is ​​integrally covered on the outside of the track body, and the rubber matrix is ​​integrally formed and connected by a vulcanization process.

[0009] According to the present invention, a novel rubber track is provided, wherein the outer surface of the rubber substrate is provided with a plurality of parallel protruding teeth, the cross section of the protruding teeth is trapezoidal or arc-shaped, the spacing between adjacent protruding teeth is 10-30mm, and the tooth height is 3-6cm.

[0019] This application provides a novel rubber track, including a track body 1, which is internally provided with a drive wheel 2, a support roller 3 and a driven wheel 4. The inner surface of the track body 1 is integrally formed with a drive tooth profile, the tooth profile having a trapezoidal cross section and a rounded transition fillet with a radius R=2-5mm at the tooth root, for meshing and transmission with the drive wheel 2. The inner side of the track body 1 is provided with a roller support part, which consists of convex strips that are adapted to the outer periphery of the support roller 3 and are evenly distributed along the circumference of the track. The track body 1 has driven wheel connecting parts at both ends, which are in contact with the outer wall of the driven wheel; The track body 1 is covered with a rubber matrix 5, and the track body 1 is formed by several chain links 11 being hinged in sequence by pins to form a closed ring.

[0020] The number of support rollers 3 is 3-5, and they are evenly distributed at equal intervals along the circumference of the track body 1; the axes of the drive wheel 2, the support rollers 3 and the driven wheel 4 are parallel to each other.

[0021] The rubber substrate 5 is integrally formed and connected to the outer side of the track body 1 through a vulcanization process. The outer surface of the rubber substrate 5 is provided with several parallel protrusions 51. The cross-section of each protrusion 51 is trapezoidal or arc-shaped, the spacing between adjacent protrusions is 10-30mm, and the tooth height is 3-6cm. The edge of the tooth tip of each protrusion 51 is provided with a rounded chamfer with a radius r = 1-3mm, and the bottom of the groove between adjacent protrusions 51 is a rounded surface with a radius of curvature R1 = 2-4mm to improve grip stability and avoid stress concentration.

[0022] The outer surface of the track body 1 is provided with several circumferentially spaced grooves. The rubber matrix 5 fills the grooves during vulcanization molding to form a mechanical interlocking structure and enhance the connection strength between the two.

[0023] Working principle: When the drive wheel 2 rotates, its teeth mesh with the drive tooth profile integrally formed on the inner side of the track body 1. This drive tooth profile adopts a trapezoidal cross-section design with a rounded transition fillet at the tooth root. This ensures torque transmission efficiency and disperses meshing stress through the rounded transition, preventing fatigue fracture of the drive tooth profile of the track body 1 due to stress concentration, thus achieving smooth power output. The support roller 3 rolls in cooperation with the support roller support part on the inner side of the track body 1. At the same time, the axes of the drive wheel 2, support roller 3, and driven wheel 4 are parallel to each other, ensuring uniform force distribution on the track body 1 during movement, preventing uneven wear, effectively distributing the load on the track and equipment, and improving the smoothness and stability of equipment operation. The rubber matrix 5 completely covers the outer side of the track body 1. Its outer surface is provided with several parallel protruding teeth 51. The cross-section of each tooth 51 is trapezoidal or arc-shaped, with an adjacent spacing of 10-30mm and a tooth height of 3-6cm. This tooth deformation increases the contact friction with the ground, adapting to complex terrains such as mud and soft surfaces. Furthermore, the tooth tip edge of each tooth 51 has a rounded chamfer with a radius r = 1-3mm, and the bottom of the groove between adjacent teeth 51 has a rounded transition surface, further dispersing grip stress and preventing the rubber matrix 5 from cracking due to sharp edges, thus balancing grip performance and durability. Simultaneously, the outer surface of the track body 1 has circumferentially spaced grooves. The rubber matrix 5 fills these grooves during vulcanization, creating a mechanical interlocking structure, strengthening the connection strength, and resisting the risk of peeling under alternating stress and harsh working conditions. The track body 1 is formed by several links that are hinged together in sequence by pins to form a closed loop. It can rotate flexibly according to the support posture of the drive wheel 2, driven wheel 4 and support roller 3, adapting to the deformation requirements of complex working conditions such as climbing and turning. The hinge design of the links balances the structural strength and the flexibility of movement, ensuring the adaptability of the track system in different terrains.

[0024] Therefore, this utility model provides a novel rubber track with trapezoidal or arc-shaped protruding teeth on the rubber surface, combined with the rounded chamfer at the tooth tip and the rounded transition of the groove. This significantly enhances the grip friction through tooth deformation and reduces the stress concentration coefficient, thus simultaneously improving the passability in muddy and soft terrain and the durability of the rubber, extending its service life. Three to five support rollers are evenly distributed at equal intervals and parallel to the axes of the drive and driven wheels, making the track more evenly stressed, reducing vibration amplitude, minimizing localized wear, and improving the smoothness of equipment operation. The drive tooth root is equipped with a rounded transition fillet, reducing the meshing stress concentration coefficient. Combined with the optimized transition of the rubber protruding teeth, this significantly improves fatigue resistance. The track body is hinged with chain link pins to form a closed loop, which can flexibly adapt to the curvature changes of the drive wheel, support rollers, and driven wheels, meeting the deformation requirements of complex working conditions such as climbing and turning, achieving a balance between structural strength and flexibility.
