the spoke includes back bracing piece, the front end of back bracing piece is fixed with the spoiler, the front end of spoiler is fixed with preceding bracing piece, the one end of preceding bracing piece and back bracing piece is fixed with the connecting block.

Preferably, bolt fixing holes are formed in the surface of the offset distance, the fixing holes are uniformly distributed in the surface of the offset distance, and the connecting blocks are annularly distributed in the surface of the offset distance.

Preferably, the cross sections of the front support rod and the rear support rod are triangular.

Preferably, the front support rod and the rear support rod are obliquely arranged relative to the connecting block and have equal inclination angles, and the inclination directions of the front support rod and the rear support rod relative to the connecting block are opposite.

Preferably, three spoilers are equidistantly arranged on the surfaces of the front support rod and the rear support rod, and the spoilers are obliquely arranged relative to the front support rod and the rear support rod.

Preferably, the three spoilers have the same inclination angle on the surfaces of the front supporting rod and the rear supporting rod.

Preferably, the surface of the connecting block is provided with two groups of front support rods, spoilers and rear support rods, and the angles of the front support rods, the spoilers and the rear support rods are opposite.

Preferably, the surface of the retainer ring is uniformly provided with ball grooves, and the concave profiles of the ball grooves are equal.

Compared with the prior art, the automobile hub with the new structure has the following beneficial effects:

1. the invention provides the ball groove, so that the overall mass of the automobile hub is reduced through the ball groove, the load of an automobile is reduced, and the endurance mileage of the automobile is increased.

2. The invention provides a double-layer spoke structure, and the design of staggered two-layer spokes is innovatively adopted, so that the integral stress performance of the hub is better through the front supporting rod and the rear supporting rod.

3. The invention provides a multilayer spoiler blade between two layers of spokes, wherein the spoiler blade has excellent aerodynamic characteristics, and can effectively reduce wind resistance and guide part of air flow to blow a brake system at the inner side of a hub when an automobile runs at high speed, so that the energy consumption of the automobile is reduced and the running safety of the automobile is improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment is given by figures 1-3, the invention comprises a novel-structure automobile hub, which comprises a rim 6, wherein two ends of the rim 6 are fixedly provided with retaining rings 1, the inner surface of each retaining ring 1 is fixedly provided with a spoke 2, the middle of each spoke 2 is provided with a ball groove 3 at the inner surface position of the retaining ring 1, the middle of each spoke 2 is fixedly provided with an offset 5, the rear part of each spoke 2 is fixedly provided with a groove bottom 4 at the inner position of the rim 6, and the front end of each groove bottom 4 is provided with an air valve 7;
