Description

Wheel hub cover fixing device and wheel hub

technical field

The utility model belongs to the technical field of auto parts, in particular to a hub cover fixing device and a hub.

Background technique

At present, the installation methods of the existing automobile hub caps are various and inconsistent, and it is very troublesome to install and replace them on the hub. After installation, the connection between the hub cap and the hub is not very firm, and the outer edge does not fit very well. During driving, the hubcap will produce abnormal noise, noise or loosen and fall off, especially under special circumstances such as temperature and climate, wading, uneven roads, muddy and other special circumstances.

In terms of applicability, there are many models and specifications of existing iron hubs. For wheels with the same size and different models and specifications, different hub caps need to be configured, and the hub caps have poor versatility. For hub caps of the same size and model, due to tolerances, the diameters of the grooves of the hubs are also different, and the tightness of the matching hub caps after installation is also different. It brings trouble to the installation, and it is easy to loosen and fall off, which increases the use cost of the hubcap.

In actual use, the hub cap is located on the high-speed wheel hub. Due to heat and vibration, the buckle of the hub cap is easily deformed and worn. In wet and rainy weather, the retaining spring on the hub cap will corrode and rust, and the elasticity will decrease, causing the hub cap to be damaged. The connection to the hub is not strong. Changing the wheel hub or repairing the tire, the hub cap is often assembled and removed, and the buckle of the hub cap is easily worn. If the hub is equipped with a balance weight or the edge of the hub is slightly deformed, the outer edge of the hub cover does not fit the hub after installation, the concentricity of the hub cover is poor, and the hub cover is easy to fall off when driving at high speed or wading through water.
