Abstract

The present invention provides a method for dissipating heat from an automobile wheel hub, a device thereof, and an automobile, wherein the method for dissipating heat from an automobile wheel hub comprises the following steps: obtaining a current driving state signal of the automobile; the driving state signal includes a normal driving state signal and a braking state signal; Control the running state of the hub and spokes according to the current running state signal; if the running state signal is a normal running state signal, control the plurality of spokes of the hub to be at a predetermined first position; if the running state signal is a braking state signal, control the hub The plurality of spokes are deflected from the current position toward the predetermined second position. The apparatus is used to implement the method, and the vehicle includes the apparatus. The invention solves the technical problem that the existing in-wheel motor cooling method cannot take into account the improvement of the cooling effect of the in-wheel motor in the braking process of the vehicle and the aerodynamic performance in the normal driving process of the vehicle.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile hub heat dissipation method and device thereof, and an automobile. Background technique [0002] Braking performance is an important performance of a car, which is directly related to the reliability of the vehicle and the safety of human life. However, the brake device is greatly affected by temperature. At high temperatures, the braking performance of the brake disc and caliper decreases sharply, that is, the thermal attenuation of the braking performance. 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 development direction of my country's and even global car companies. The hub...
