Description

Technical Field

[0001] This utility model relates to the field of rubber wheel technology, and in particular to an anti-slip rubber wheel. Background Technology

[0002] Rubber wheels are ring-shaped elastic rubber products installed on various vehicles or machinery. They are typically mounted on metal rims and are used to support the vehicle body, cushion external impacts, reduce vibration, and lower operating temperatures. In current designs, rubber wheel surfaces usually only have a single layer of anti-slip texture.

[0003] Over time, especially with frequent movement and turning, the lateral friction between the rubber wheels and the ground will gradually wear down the anti-slip texture. Once the anti-slip texture is worn down, the anti-slip performance of the rubber wheels will decrease, affecting overall safety and efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-slip rubber wheel in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-slip rubber wheel includes a rim and a rubber ring that is interference-fitted with the outer ring of the rim. The outer surface of the rubber ring has the following components arranged in a ring array around its axial direction:

[0007] The first trapezoidal protrusion and the second trapezoidal protrusion are distributed alternately, and the protrusion heights of the two sets of trapezoidal protrusions are different.

[0008] The first trapezoidal groove and the second trapezoidal groove are distributed at intervals between adjacent first trapezoidal protrusions and second trapezoidal protrusions, and the two sets of trapezoidal grooves have different recess depths.

[0009] As a further description of the above technical solution:

[0010] The rim is provided with limiting rings at both ends with an outer diameter larger than the outer diameter of the rim, and the rubber ring is provided with second assembly grooves on both sides that cooperate with the limiting rings.

[0011] As a further description of the above technical solution:

[0012] The limiting ring includes:

[0013] The first limiting ring is fixedly connected to one end of the wheel rim;

[0014] The second limiting ring is detachably connected to the other end of the wheel rim.

[0015] As a further description of the above technical solution:

[0016] The other end of the rim is provided with a first mounting groove that mates with the second limiting ring. Several first studs are fixedly arranged in a ring array around the second limiting ring along its axial direction. The rim and the first limiting ring are provided with first positioning holes for accommodating the first studs. Each set of first studs is locked by a lock nut.

[0017] As a further description of the above technical solution:

[0018] The other end face of the rim is fixedly arranged in a ring array around its axial direction with a number of second studs. The second studs are arranged at intervals with the first studs. The second limiting ring is provided with a number of second positioning holes to accommodate the second studs. Each group of second studs is locked by a lock nut.

[0019] As a further description of the above technical solution:

[0020] The outer end faces of the first limiting ring and the second limiting ring are respectively provided with annular grooves for accommodating locking nuts.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, when the higher first trapezoidal protrusion is gradually worn down due to long-term friction, the lower second trapezoidal protrusion below or adjacent to it still maintains a certain height, thus forming a second anti-slip layer that continues to function. That is, as the outer anti-slip structure wears down, the inner layer or a lower-level anti-slip structure can automatically "take over" to provide friction, thereby extending the overall effective service life of the tire and the continuity of its anti-slip performance. Ultimately, even if the outer rubber layer is worn down to the bottom of the second trapezoidal groove, the remaining structure still has a certain anti-slip foundation and will not experience a sudden drop in anti-slip capability. This effectively solves the problem of the sharp decline in anti-slip performance of traditional single-pattern tires after wear, and significantly improves the safety and durability of rubber wheels under complex working conditions.

[0023] 2. In this utility model, when the rubber ring is severely worn, the locking nut can be removed, the second limiting ring can be taken off, the old rubber ring can be removed from the rim, and a new rubber ring can be replaced and reassembled. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-5 This utility model provides a technical solution: an anti-slip rubber wheel, including a rim 1 and a rubber ring 5 that is interference-fitted with the outer ring of the rim 1. The outer surface of the rubber ring 5 has a ring array of first trapezoidal protrusions 51 and second trapezoidal protrusions 52 arranged in a ring around its axis. The two sets of trapezoidal protrusions are spaced apart and have different protrusion heights, so that the rubber wheel can form multi-point support when in contact with the ground, effectively improving the ground contact area and friction coefficient. First trapezoidal grooves 501 and second trapezoidal grooves 502 are spaced apart between adjacent first trapezoidal protrusions 51 and second trapezoidal protrusions 52, and have different recess depths. These grooves are not only used to guide drainage and dust removal, but also to generate dynamic pressure changes during tire rolling, further enhancing grip performance.

[0033] In this embodiment, during use, when the higher first trapezoidal protrusion 51 is gradually worn down due to long-term friction, the lower second trapezoidal protrusion 52 below or adjacent to it still maintains a certain height, thus forming a second anti-slip layer that continues to function. That is, as the outer anti-slip structure wears down, the inner layer or a lower-level anti-slip structure can automatically "take over" to provide friction, thereby extending the overall effective service life of the tire and the continuity of its anti-slip performance. Finally, even if the outer rubber layer is worn down to the bottom of the second trapezoidal groove 502, the remaining structure still has a certain anti-slip foundation and will not experience a sudden drop in anti-slip capability. This effectively solves the problem of the sharp decline in anti-slip performance of traditional single-pattern tires after wear, and significantly improves the safety and durability of rubber wheels under complex working conditions.

[0034] Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, the two ends of the rim 1 are provided with limiting rings with an outer diameter larger than the outer diameter of the rim 1. The rubber ring 5 has a second assembly groove 503 on both sides that cooperates with the limiting rings, which plays an auxiliary positioning and sealing role. The limiting ring includes: a first limiting ring 2 fixedly connected to one end of the rim 1; a first mounting groove 101 that mates with a second limiting ring 7 is opened at the other end of the rim 1; a plurality of first studs 3 are fixedly arranged in a ring array around the axial direction of the second limiting ring 7; a first positioning hole 202 for accommodating the first studs 3 is opened on the rim 1 and the first limiting ring 2; a plurality of second studs 6 are fixedly arranged in a ring array around the axial direction of the other end face of the rim 1; the second studs 6 are spaced apart from the first studs 3; and the overall structure is stably connected by staggered arrangement and locking nut 4; a plurality of second positioning holes 701 for accommodating the second studs 6 are opened on the second limiting ring 7; each set of first studs 3 and second studs 6 is locked by locking nut 4; the limiting rings at both ends of the rim 1 are fastened by studs and nuts to prevent the rubber ring 5 from coming off at high speed or under bumpy conditions; and annular grooves 201 for accommodating locking nut 4 are opened on the outer end faces of the first limiting ring 2 and the second limiting ring 7 respectively to avoid protrusion affecting aesthetics and safety. When the rubber ring 5 is severely worn, the locking nut can be removed, the second limit ring 7 can be taken off, the old rubber ring can be removed from the rim 1, and a new rubber ring can be replaced and reassembled.

[0035] Working principle: During use, the rim 1 drives the rubber ring 5 to move synchronously. The trapezoidal protrusions on the outer surface of the rubber ring 5 first contact the ground, providing initial friction to ensure stable starting. As the vehicle moves, the tire rolls continuously, and the trapezoidal protrusions continue to contact the ground. In the case of turning or slippery road conditions, the protrusions of different heights and the grooves of different depths work together to increase lateral grip and prevent slippage. If encountering muddy or waterlogged sections, the trapezoidal grooves can quickly drain water and impurities, reducing the "water drift effect" and maintaining good adhesion. Over time, when the higher first trapezoidal protrusion 51 is gradually worn down due to long-term friction, the lower second trapezoidal protrusion 52 below or adjacent to it still maintains a certain height, thus forming a second anti-skid layer that continues to play a role. Even if the outer layer of rubber is worn down to the bottom of the second trapezoidal groove 502, the remaining structure still has a certain anti-skid foundation and will not experience a sudden drop in anti-skid ability. This effectively solves the problem of the sharp decline in anti-skid performance of traditional single-pattern tires after wear, and significantly improves the safety and durability of rubber wheels under complex working conditions.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
