Description

Technical Field

[0001] This utility model relates to the field of wheel rim technology, specifically to an impact-resistant wheel rim. Background Technology

[0002] With the continuous development of the automotive industry, the performance requirements for wheel rims are also constantly increasing. As an important component of the vehicle's driving system, the performance of wheel rims directly affects the vehicle's driving safety and comfort. Traditional wheel rims are prone to deformation, cracking, or even breakage when subjected to large impacts, such as when driving on bumpy roads or encountering obstacles. This not only affects the normal driving of the vehicle but may also lead to serious traffic accidents.

[0003] In the present technology, most wheel rims are made by integral stamping or casting, which has a simple structure and lacks effective impact resistance design. When subjected to impact, the impact force is directly applied to a local area of ​​the rim, which can easily lead to stress concentration in that area and thus damage to the rim.

[0004] Therefore, an impact-resistant wheel rim is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an impact-resistant wheel rim in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An impact-resistant wheel rim includes a rim, an inner supporting ring fixedly installed on the inner wall of the rim, an impact buffer assembly provided on the inner supporting ring, and an annular guard plate connected to the end of the impact buffer assembly for protecting the surface of the rim, thereby buffering and absorbing the impact force.

[0008] Furthermore, the wheel rim includes a wheel rim, a spoke is fixedly installed on the inner wall of the wheel rim, a supporting inner ring is fixedly installed on the inner wall of the wheel rim, and a wheel hub is fixedly installed at the end of the spoke.

[0009] Furthermore, triangular support blocks are fixedly installed on the surfaces of the rim and spokes to increase the connection strength between the rim and spokes.

[0010] Furthermore, the impact buffer assembly includes a damping rod fixedly installed on the surface of the inner ring of the support. The movable part of the damping rod is movably inserted into the inner ring of the support, and an annular guard plate is fixedly connected to its end. A spring is sleeved on the movable part of the damping rod. The two ends of the spring are fixedly connected to the annular guard plate and the inner ring of the support, respectively. A corrugated rubber sleeve is connected between the annular guard plate and the inner ring of the support, and the spring is located inside the corrugated rubber sleeve.

[0011] Furthermore, a rubber ring is fixedly installed on the surface of the annular guard plate, and the rubber ring is arranged in a corresponding manner to the surface of the wheel rim.

[0012] Furthermore, both the rubber ring and the corrugated rubber sleeve are made of elastic rubber material.

[0013] The beneficial effects of this utility model are as follows:

[0014] The inner ring is used to strengthen the internal support structure of the wheel rim and improve its overall strength. The shock-absorbing assembly is connected to a ring-shaped guard plate to protect the surface of the wheel rim from direct impact. The shock-absorbing assembly can buffer and absorb the impact force, effectively reducing the damage to the wheel rim and protecting the integrity and functionality of the wheel rim when it is impacted.

Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1 to 4 As shown, an impact-resistant wheel rim includes a rim 1, with a supporting inner rim 2 fixedly installed on the inner wall of the rim 1; as Figure 1 and Figure 2 As shown, specifically, the wheel rim 1 includes a rim 101, a spoke 102 is fixedly installed on the inner wall of the rim 101, a supporting inner ring 2 is fixedly installed on the inner wall of the rim 101, and a hub 103 is fixedly installed at the end of the spoke 102.

[0025] More specifically, the inner ring 2 is fixedly installed on the inner wall of the rim 101, and the hub 103 is fixedly installed at the end of the spoke 102. The hub 103, as the central part of the entire steel rim, is responsible for connecting with the axle, which improves the overall stability and load-bearing capacity of the steel rim.

[0026] like Figure 3 As shown, in some practical applications, triangular support blocks 5 are fixedly installed on the surfaces of the rim 101 and the spokes 102 to increase the connection strength between the rim 101 and the spokes 102.

[0027] More specifically, when encountering an impact, the triangular support block 5 can evenly distribute the stress, avoiding deformation or damage caused by local stress concentration, and improving the stability and impact resistance of the entire steel ring structure.

[0028] An impact buffer assembly 3 is provided on the inner ring 2, and an annular guard plate 4 is connected to the end of the impact buffer assembly 3 to protect the surface of the wheel rim 1. The impact buffer assembly 3 buffers and absorbs the impact force. Figure 4As shown, specifically, the impact buffer assembly 3 includes a damping rod 301 fixedly installed on the surface of the inner support ring 2. The movable part of the damping rod 301 is movably inserted into the inner support ring 2, and an annular guard plate 4 is fixedly connected to its end. A spring 302 is sleeved on the movable part of the damping rod 301. The two ends of the spring 302 are fixedly connected to the annular guard plate 4 and the inner support ring 2, respectively. A corrugated rubber sleeve 303 is connected between the annular guard plate 4 and the inner support ring 2, and the spring 302 is located inside the corrugated rubber sleeve 303.

[0029] More specifically, the annular guard plate 4 serves as the first protective barrier, directly contacting and buffering external impact forces. A spring 302 is fitted onto the movable part of the damping rod 301, and the elastic deformation of the spring 302 further absorbs and mitigates the impact force. The corrugated rubber sleeve 303 is fitted onto the outside of the spring 302, which protects the spring 302 from the influence of the external environment and also provides a certain elastic buffering effect.

[0030] like Figure 3 and Figure 4 As shown, in some practical applications, a rubber ring 6 is fixedly installed on the surface of the annular guard plate 4, and the rubber ring 6 is arranged in a corresponding manner to the surface of the rim 101.

[0031] More specifically, when an impact occurs, the rubber ring 6 first contacts the rim 101, using its elastic deformation to absorb part of the impact energy, thus playing a preliminary buffering role. At the same time, the wear resistance of the rubber ring 6 can also reduce the wear on the surface of the annular guard plate 4 and the rim 101, extending the service life of the steel ring.

[0032] like Figure 3 and Figure 4 As shown, in some practical applications, both the rubber ring 6 and the corrugated rubber sleeve 303 are made of elastic rubber material.

[0033] More specifically, the rubber ring 6 and the corrugated rubber sleeve 303 can quickly undergo elastic deformation to absorb impact energy and return to their original shape after the impact.

[0034] In summary: The inner ring 2 is used to enhance the internal support structure of the wheel rim 1 and improve its overall strength. The impact buffer assembly 3 is connected to the annular guard plate 4 to protect the surface of the wheel rim 1 from direct impact. The impact buffer assembly 3 can buffer and absorb the impact force, effectively reducing the damage to the wheel rim 1 and protecting the integrity and functionality of the wheel rim 1 when it is subjected to impact.
