Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicles, in particular to a self-heating wheel hub of a recreational vehicle. Background Art

[0002] RVs usually use a drum brake structure for braking. The disadvantage of the drum brake is that when the RV brakes, the friction between the brake shoe and the inner wall of the brake drum is very large, causing the brake drum to convert kinetic energy into heat energy. When the RV is going downhill in the mountains, it will brake frequently. Frequent braking will make the temperature of the brake drum extremely high, which can easily burn the brake shoe, resulting in the RV being unable to brake, which can easily cause driving safety accidents. Therefore, solving the heat dissipation problem of the RV wheel brake drum is an important measure to stabilize the braking performance of the RV, which will bring good news to the safety of the RV and reduce safety hazards and unnecessary economic losses of the RV.

[0003] The existing published patent number is: CN207106031U, which discloses a self-cooling circulation device for an automobile wheel hub, including a wheel hub and a rim arranged on the wheel hub for mounting an automobile tire; the wheel hub includes a hub body, and an axial hole arranged in the middle of the wheel hub body for connecting to the automobile axle, and a heat dissipation pipe arranged at the edge of the wheel hub body for reducing the temperature of the wheel hub body, and a spoke arranged on the outside of the wheel hub body for protecting the wheel hub body; the heat dissipation pipe is provided in plurality and passes through the wheel hub body, and a ventilation pipe is provided above the heat dissipation pipe, and the ventilation pipe is provided in plurality.

[0004] The above scheme can utilize the suction force generated by the wheel when it is moving to draw the outside air into the rim body through the heat dissipation pipe, and then circulate and cool the wheel. It has the advantages of simple structure, easy maintenance and obvious heat dissipation effect. By setting the heat dissipation pipe to dissipate heat for the wheel hub, the pipe may break after long-term use. Due to the location of the wheel hub, the environment is relatively harsh and the efficiency is low. Utility Model Content
