Detailed Description

As shown in fig. 1 and 2, a shock-absorbing hub for an automobile includes a rim 10, a hub 20, spokes 30 and shock-absorbing members 40. The rim 10 rolls concentrically with the hub 20. The hub 20 is located inside the rim 10 for supporting the hub 10. A plurality of spokes 30 are radially and fixedly mounted on the hub 20 and the rim 10, the spokes 30 are made of alloy steel plate with slight elastic deformation capability, specifically, referring to fig. 2, the spokes 30 include an arc-shaped fixing edge 31 fitting the rim 10 and a supporting edge 32 connecting the hub 20 and the rim 10, the fixing edge 31 is welded on the inner wall of the rim 10, the two supporting edges 32 are respectively connected to two sides of the fixing edge 31 to form the spokes 30 into an approximate triangle shape, and the fixing edge 31 and the supporting edge 32 can be integrally formed to enhance the overall strength of the spokes 30. The other end of the support edge 32 is welded to the wheel hub 20.

Referring to fig. 2, the two ends of the shock absorbing member 40 are respectively and flexibly supported to the middle of the spoke 30 and the rim 10 in an inclined manner, so that a triangular connecting structure is formed between the shock absorbing member 40 and the spoke 30, and the supporting strength of the spoke 30 to the rim 10 is enhanced. Specifically, the damper 40 includes a spring housing 41, a compression spring 42 and connecting columns, the two connecting columns are an upper connecting column 43 and a lower connecting column 44, respectively, the upper connecting column 43 is welded to the middle of the supporting rim 32, and the lower connecting column 44 is welded to the middle of the fixing rim 31, so that the upper connecting column 43 and the lower connecting column 44 support the spoke 30 and the rim 10, respectively. The ends of the two connecting columns extend into the spring housing 41, the compression spring 42 is installed in the spring housing 41, and the two ends of the compression spring respectively abut against the upper connecting column 43 and the lower connecting column 44, when the rim 10 vibrates due to bumping, the rim 10 transmits the vibration to the lower connecting column 44, and the lower connecting column 44 can upwards press the compression spring 42 to absorb the vibration of the rim 10.

In order to avoid the free up-and-down shaking of the spring housing 41, the upper connecting column 43 is fixedly connected with the top of the spring housing 41 by welding, bonding, interference connection or screwing. And there is no fixed connection structure between the lower connection column 44 and the spring housing 41, so that the lower connection column 44 can slide along the axial direction of the spring housing 41.

The ends of the upper connecting column 43 and the lower connecting column 44 are both provided with a shackle 45, and the shackle 45 hooks the end of the compression spring 42. The part of the lower connecting column 44 extending into the spring housing 41 is provided with a limiting bump 46, and the limiting bump 46 can abut against the outer ring of the compression spring 42, so that the compression spring 42 can perform stable telescopic motion.

Two shock-absorbing members 40 are symmetrically installed in each of the spokes 30, and the two shock-absorbing members 40 support the two support sides 32 of the spokes 30, respectively, so that the two shock-absorbing members 40 can uniformly absorb shock to the spokes 30.

Referring to fig. 1 and 2, since the middle portion of the supporting side 32 may be slightly deformed by the pressure of the shock absorbing member, in order to reduce the deformation amount of the supporting side 32 and improve the supporting stability of the spokes 30, a shock absorbing spring 50 is installed between two adjacent spokes 30, the shock absorbing spring 50 is also a compression type spring, and the shock absorbing spring 50 is installed in the middle portion of the supporting side 32, and can apply a pressure to the supporting side 32 opposite to the force application direction of the shock absorbing member 40, so that the supporting side 32 of the spokes 30 can quickly recover to the original straight state, and continue to provide stable support for the rim 10. In order to improve the expansion stability of the shock absorbing spring 50, a spring housing having a structure similar to that of the shock absorbing member may be installed outside the shock absorbing spring.

The working principle of the device is as follows: when the rim 10 is vibrated by bumping, the rim 10 transmits vibration energy to the lower connecting post 44 of the damper, the lower connecting post 44 presses the compression spring 42 upwards, the compression spring 42 can absorb a part of the vibration energy, and part of the vibration energy is transmitted to the supporting edge 32 of the spoke 10 through the upper connecting post 43, so that the middle part of the supporting edge 32 generates slight elastic deformation. The shock absorbing spring 50 between two adjacent spokes 30 applies a pressure to the supporting edge 32 in a direction opposite to the force applied by the shock absorbing member 40, so that the supporting edge 32 is quickly restored to the original linear state, and the shock absorbing effect is provided for the rim 10.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
