Abstract

The invention provides an automobile wheel hub heat dissipation method, a device for realizing the method and an automobile. The automobile wheel hub heat dissipation method comprises the following steps that current driving state signals of the automobile are obtained; the driving state signals comprise normal driving state signals and brake state signals; the running state of wheel spokes of a wheel hub is controlled according to the current driving state signals; if the driving state signals are the normal driving state signals, the multiple wheel spokes of the wheel hub are controlled to be located at a predetermined first position; and if the driving state signals are the brake state signals, the multiple wheel spokes of the wheel hub are controlled to perform deflection from a current position to a predetermined second position. The device is used for realizing the method, and the automobile comprises the device. By means of the automobile wheel hub heat dissipation method, the device and the automobile, the technical problem that an existing wheel hub motor cooling method cannot take both improving of the wheel hub motor cooling effect in the automobile braking process and improving of the aerodynamic performance in the automobile normal driving process into account is solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a heat dissipation method and device of an automobile wheel hub, and an automobile. Background technique [0002] Braking performance is an important performance of a vehicle, which is directly related to the reliability of the vehicle and the safety of human life. However, the braking device is greatly affected by temperature. Under high temperature, the braking performance of the brake disc and caliper decreases sharply, that is, the braking performance is thermally attenuated. During the braking process, a large amount of heat is generated due to the friction between the caliper and the brake disc. , and then affect the braking performance. Therefore, how to reduce the temperature of the braking device during driving has become an important issue in automobile design. New energy vehicles are becoming the direction of vigorous development of Chinese and even global car com...
