Description

Technical Field

[0001] The utility model relates to the technical field of wheels, in particular to a composite polyurethane wheel. Background Art

[0002] With the continuous development of industrial production, small delivery vehicles within the factory area play an increasingly important role in logistics and transportation. Due to the complex and changeable ground conditions in the factory area, such as unevenness and slopes, these small delivery vehicles are often affected by large vibrations during use, resulting in damage to the vehicle body or cargo.

[0003] Currently, the shock-absorbing mechanisms of most small delivery vehicles used within factories are primarily mounted on the vehicle frame, rather than integrated directly into the wheels. While this design can absorb and mitigate ground impact to a certain extent, the proximity of the shock-absorbing elements to the vehicle body makes the damping effect less than ideal. When the vehicle travels on uneven surfaces, vibrations are transmitted through the wheels to the frame, and from there to the vehicle body and cargo, causing the cargo to sway and even damage. Therefore, we propose a composite polyurethane wheel to address this issue. Summary of the Invention

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] A composite polyurethane wheel comprising:

[0006] The stainless steel wheel ring is annular, and the outer surface of the stainless steel wheel ring is configured with an annular array of arc grooves, and the arc grooves are configured with circular holes penetrating the stainless steel wheel ring;

[0007] A hexagonal block is arranged in the middle of the stainless steel wheel ring. Connecting plates are fixed between the six corners of the hexagonal block and the inner wall of the stainless steel wheel ring. A reinforcing plate is provided between the middle parts of the connecting plates. A circular channel is constructed in the middle of the hexagonal block, and the circular channel is used to install and fix the wheel axle;

[0008] The shock-absorbing component is arranged in the arc-shaped groove and is used to reduce the impact of vibration on the vehicle body.

[0009] Furthermore, the shock-absorbing assembly includes a stainless steel column embedded in the arc-shaped groove, a connecting rod passing through a circular hole is connected to one side of the stainless steel column, a mounting tube is fixed to the side wall of the hexagonal block, a damping rod is installed on the side of the mounting tube close to the hexagonal block, the end of the connecting rod away from the stainless steel column slides through the top wall of the mounting tube and extends into the interior of the mounting tube, and the reinforcing plate is provided with a limit member, which is used to limit the front and rear position of the connecting rod.

[0010] Furthermore, the limiting member includes a limiting rod, a strip hole is constructed in the middle of the connecting rod, a limiting hole is constructed in the middle of the reinforcing plate, the limiting rod slides through the limiting hole and the strip hole, a limiting plate is fixed at one end of the limiting rod, and a nut is threadedly connected to the other end.

[0011] Furthermore, the surface of the stainless steel column is covered with a polyurethane sleeve.

[0012] Furthermore, a buffer pad is slidably provided inside the mounting cylinder between the damping rod and the connecting rod, and the buffer pad is an elastic rubber pad.

[0013] Furthermore, anti-slip protrusions are evenly distributed on the outer surface of the stainless steel wheel ring at intervals between the arc-shaped grooves.

[0014] The beneficial effects of the utility model are as follows:

[0015] The utility model integrates the shock-absorbing assembly into the wheel. When the carrier vehicle travels on an uneven road, the wheel will be impacted by the ground.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] The present application provides a composite polyurethane wheel, which is mainly used to solve the problem that in the prior art, the shock-absorbing mechanism of most small transport vehicles in factory areas is mainly installed on the frame rather than directly integrated into the wheel. Although this design can absorb and alleviate the impact from the ground to a certain extent, the shock-absorbing element is too close to the vehicle body, and its shock-absorbing effect is not ideal. When the vehicle is traveling on an uneven road, the vibration will be transmitted to the frame through the wheel, and then transmitted to the vehicle body and cargo by the frame, causing the cargo to shake or even be damaged. The following technical solutions are provided, which will be combined with Figure 1-Figure 5 Give detailed instructions:

[0025] A composite polyurethane wheel, comprising:

[0026] The stainless steel wheel ring 1 is annular, and has an annular array of arc grooves 101 on its outer surface, and a circular hole 102 penetrating the stainless steel wheel ring 1 is formed in the arc groove 101;

[0027] The hexagonal block 2 is arranged in the middle of the stainless steel wheel ring 1. A connecting plate 3 is fixed between the six corners of the hexagonal block 2 and the inner wall of the stainless steel wheel ring 1. A reinforcing plate 4 is arranged between the middle of the connecting plate 3. A circular channel 201 is constructed in the middle of the hexagonal block 2. The circular channel 201 is used to install and fix the wheel axle;

[0028] The shock-absorbing assembly 5 is arranged in the arc groove 101 and is used to reduce the impact of vibration on the vehicle body. The shock-absorbing assembly 5 includes a stainless steel column 501 embedded in the arc groove 101. One side of the stainless steel column 501 is connected to a connecting rod 502 that passes through the circular hole 102. A mounting tube 505 is fixed to the side wall of the hexagonal block 2. A damping rod 503 is installed on the side of the mounting tube 505 close to the hexagonal block 2. The end of the connecting rod 502 away from the stainless steel column 501 slides through the top wall of the mounting tube 505 and extends into the interior of the mounting tube 505. The reinforcing plate 4 is provided with a limit member 6, which is used to limit the front and rear position of the connecting rod 502.

[0029] Working principle:

[0030] The composite polyurethane wheel integrates a shock-absorbing assembly 5 into the wheel. When the carrier travels on an uneven road, the wheel will be impacted by the ground. These impact forces first act on the stainless steel column 501 and are then transmitted to the damping rod 503 through the connecting rod 502. The damping rod 503 can effectively absorb the vibration energy, convert it into other forms of energy and release it, reducing the impact on the vehicle body and cargo. During installation and use, the stainless steel column 501 is embedded in the arc groove 101, so that the connecting rod 502 passes through the circular hole 102 and enters the interior of the installation tube 505 to interfere with the damping rod 503. The range of motion of the connecting rod 502 is set by adjusting the position of the limit rod 601, thereby controlling the maximum compression and restoring force of the shock-absorbing assembly 5. The wheel axle is passed through the circular channel 201 in the middle of the hexagonal block 2 and is firmly mounted on the chassis of the carrier using appropriate fixing devices (such as nuts 603, washers, etc.). It can then be used. It should be noted that the damping rod 503 is a prior art, and one of the product models is JG / T 209-2012, its working principle is that when the structure produces interlayer deformation under the action of vibration, the energy-absorbing components of the damper undergo plastic deformation to consume the energy input into the structure, thereby achieving a shock-absorbing effect.

[0031] like Figure 3 As shown, in some embodiments, the limiting member 6 includes a limiting rod 601, a strip hole 5021 is constructed in the middle of the connecting rod 502, and a limiting hole 401 is constructed in the middle of the reinforcing plate 4. The limiting rod 601 slides through the limiting hole 401 and the strip hole 5021. A limiting plate 602 is fixed at one end of the limiting rod 601, and a nut 603 is threadedly connected to the other end. More specifically, the limiting rod 601 passes through the strip hole 5021 of the connecting rod 502 and the limiting hole 401 of the reinforcing plate 4 to limit the forward and backward movement range of the connecting rod 502. The limiting plate 602 is installed at one end of the limiting rod 601 to prevent the limiting rod 601 from being over-inserted into or out of the limiting hole 401. The nut 603 is used to fix the limiting plate 602 to the end of the limiting rod 601 and fix the limiting rod 601 through a threaded connection.

[0032] like Figure 3 As shown, in some embodiments, the surface of the stainless steel column 501 is provided with a polyurethane sleeve 5011. More specifically, the polyurethane sleeve 5011 is wrapped around the surface of the stainless steel column 501. When the transport vehicle travels on an uneven road, the wheels will be impacted by the ground. These impact forces first act on the polyurethane sleeve 5011 on the stainless steel column 501. Since the polyurethane material has good elasticity and cushioning properties, it can effectively absorb and disperse the impact force, reducing the impact on the vehicle body and cargo.

[0033] like Figure 4 As shown, in some embodiments, a buffer pad 504 is slidably provided inside the mounting cylinder 505 between the damping rod 503 and the connecting rod 502. The buffer pad 504 is an elastic rubber pad. More specifically, the setting of the buffer pad 504 changes the contact between the connecting rod 502 and the damping rod 503 from rigid contact to flexible contact, which can reduce noise and vibration transmission.

[0034] like Figure 5 As shown, in some embodiments, the outer surface of the stainless steel wheel ring 1 is evenly distributed with anti-skid protrusions 103 at the intervals of the arc groove 101. More specifically, the anti-skid protrusions 103 are made of highly wear-resistant material and have good anti-aging properties. The anti-skid protrusions 103 are located at the intervals of the arc groove 101, and improve the grip and stability of the wheel by increasing friction.

[0035] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
