Novel hub for sedan car

Abstract

The invention discloses a new wheel hub for cars, which includes a hub body, the hub body includes an outer hub and an inner hub, the outer hub and the inner hub are fixedly connected by buckles, and the buckles are evenly distributed on the connection of the rim On the surface, the buckle includes a fixed clip and a connecting clip, the connecting clip is connected with the fixed clip, the surface of the outer hub is provided with spokes, and the spokes are evenly distributed inside the rim, and the outer A fixing seat is arranged at the center of the hub, and a plurality of fixing holes are evenly arranged on the surface of the fixing seat, through holes are arranged between the spokes, and inclined wheel grooves are arranged on the edge of the through holes near the rim. By setting fan blade-type spokes on the surface of the outer hub, during the rotation of the hub, the air inside the hub is drawn out to the outside, which improves the heat dissipation efficiency of the bearing inside the hub and improves the service life of the bearing; by using the buckle connection type The wheel hub reduces the difficulty of operation when installing tires.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a novel wheel hub for small cars. Background technique [0002] The car wheel hub is a cylindrical metal part in the car tire that is centered on the shaft to support the tire. It is the part where the axle is installed in the center of the wheel. It is an important part that connects the brake drum, the wheel disc and the half shaft. The middle part of the tire is connected with the rotating bearing of the car, so as to achieve the purpose of moving the car. The wheel hub of the car is a part of the non-stop operation of the car, so the long-term driving of the car will cause the internal fixing bolts to loosen. Produce huge potential safety hazard; On the other hand, the long-time work of the brake on the automobile hub can cause the brake to overheat and cause damage to the brake. [0003] At present, when replacing tires on the wheel hubs on the market, the operation is relatively ...

[0002] The car wheel hub is a cylindrical metal part in the car tire that is centered on the shaft to support the tire. It is the part where the axle is installed in the center of the wheel. It is an important part that connects the brake drum, the wheel disc and the half shaft. The middle part of the tire is connected with the rotating bearing of the car, so as to achieve the purpose of moving the car. The wheel hub of the car is a part of the non-stop operation of the car, so the long-term driving of the car will cause the internal fixing bolts to loosen. A huge potential safety hazard; on the other hand, the long-term work of the brake on the wheel hub of the car will cause the brake to overheat and cause damage to the brake

[0003] At present, when replacing tires on the wheel hubs on the market, the operation is relatively complicated, and usually requires special machinery to assist, and manual operation is more difficult. When the vehicle is running for a long time, the bearings in the hub tend to generate high temperature, and the heat dissipation through air cooling is slow, which is not easy. Cool down the bearing and reduce the service life of the bearing
