It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: shown in connection with fig. 1-4, includes a hub 1; the hub 1 comprises a rim 2 and spokes 3; the two sides of the rim 2 in the circumferential direction are symmetrically provided with bead seats 201; the outer end of the bead seat 201 on one side of the rim 2 is provided with a mounting groove 202; a reinforcing rib 203 is arranged inside the rim 2; a tire 204 is arranged outside the rim 2; the two sides of the tire 204 are clamped with the bead seats 201; the mounting groove 202 is rectangular; the reinforcing ribs 203 are spiral; a plurality of groups of spokes 4 are uniformly arranged in the circumferential direction of the spoke 3; the central position of the spoke 3 is provided with a mounting seat 301; one ends of a plurality of groups of spokes 4 are welded with the spokes 3; the other ends of the multiple groups of spokes 4 are welded with the mounting seat 301; an arc-shaped limiting block 401 is arranged at one end, close to the rim 2, of the spoke 4; two ends of the arc-shaped limiting block 401 are symmetrically provided with limiting clamping heads 402; a support frame 403 is arranged on one side of the spoke 4 close to the mounting seat 301; the support frame 403 is prismatic; the illustrated support bracket 403 is provided with a shock absorber 404 at a length-wise centered position; one end of the shock absorber 404 is in threaded connection with the mounting base 301; the other end of the shock absorber 404 is connected with the support frame 403 through a bolt.

When the buffering damping wheel hub for the heavy-duty automobile is used, as shown in fig. 1, when a user drives the heavy-duty automobile and frequently walks in a place with poor road conditions, the automobile body jolts seriously, the wheel hub 1 deforms seriously, the tire 204 is broken, and driving safety is affected;

step two, as shown in fig. 2-4, when a user uses the wheel hub 1 of the present invention, when the user encounters a groove or a road section with poor road conditions, the tire 204 is in contact with the groove, the bead seat 201 and the tire 204 on the upper portion of the wheel hub 1 are forced to be compressed inwardly, thereby generating deformation, and if the fulcrum of the deformation is the connection between the spoke 4 and the rim 2, the central position of the arc-shaped limiting block 401 compresses the supporting frame 403, because the supporting frame 403 is prismatic, the prismatic shape has higher strength than the circular or square shape, the supporting frame 403 starts to deform along the transverse direction of the prismatic shape, and the shock absorber 404 inside the supporting frame starts to compress, thereby absorbing the impact on the wheel hub 1 caused by the groove, and after the wheel hub 1 passes through the groove, the shock absorber 404 pushes the supporting frame 403 and the wheel hub 1 to return, so that the tyre 204 and the hub 1 maintain normal running;

step three, as shown in fig. 2-4, if the acting point of the groove and the hub 1 is the middle of two spokes 4, since the spokes 4 are not provided here, the rim 2 and the tyre 204 here now start to be forced inwards, so that the arc-shaped limit blocks 401 at the two sides of the position are deformed, and at the moment, the limit clamp 402 is deformed inwards, and thus the other limit clip 402, prevents the rim 2 and tire 204 from continuing to compress inwardly, and as the tire 204 passes over the groove, because the arc-shaped limiting block 401 has higher strength, the limiting chuck 402, the hub 1 and the tire 204 are driven to reset, so as to reduce the impact on the hub 1 and the tire 204 through the grooves, while the spiral-shaped reinforcing ribs 203 are provided inside the rim 2, thereby further improving the strength of the hub 1, ensuring the driving safety and improving the driving comfort of the driver;

step four, as shown in fig. 2-4, a mounting groove 202 is further formed in the bead seat 201 of the rim 2, so that a user can conveniently use a crowbar to mount and dismount the outer tire from the mounting groove, thereby preventing the edge of the bead seat 201 of the conventional rim 2 from being worn by the crowbar, and prolonging the service life of the hub 1.
