Problems solved by technology

Obviously, the wheel shaft is the core of the load-bearing and transmission structure, and the holes on it increase the risk of the vehicle, while the suspension pipe is located at the bottom of the vehicle, the environment is more complicated, and it is easy to be damaged and worn. These two heat dissipation methods have obvious deficiencies. place

Abstract

The invention discloses an electric automobile hub generator device which comprises an axle, a brake mechanism, a hub and a generator, the brake mechanism comprises a brake disc and a brake caliper, the generator comprises a stator and a rotor, the hub, the brake disc and the rotor are fixedly connected to the axle, the stator comprises a closed shell, and a sealing cavity is formed in the closed shell; the coil winding is immersed in the sealing cavity through cooling liquid, one side plate of the sealing shell is a heat conduction plate, a heat conduction telescopic edge is arranged on the heat conduction plate and penetrates through the brake caliper, a cooling fin is arranged at the other end of the heat conduction telescopic edge, and the cooling fin is connected with a friction plate of the brake caliper through a connecting assembly, so that when the friction plate is attached to the brake disc, the cooling fin is also attached to the brake disc. According to the hub generator device of the electric automobile, a special heat dissipation circulating pipeline does not need to be arranged for cooling liquid, and holes formed in an axle and the heat dissipation circulating pipeline suspended at the bottom of the automobile are avoided.

Description

technical field [0001] The invention relates to electric vehicle technology, in particular to an electric vehicle hub generator device. Background technique [0002] It is known that the automobile brake system converts kinetic energy into heat energy through the friction of the brake caliper and the brake disc to realize the braking of the automobile. Obviously, the automobile has a large amount of braking kinetic energy, which is directly dissipated in the form of heat energy in the prior art. Due to the effectiveness of the battery capacity of electric vehicles, some electric vehicles set generators on the hub of the vehicle to recover part of the braking kinetic energy, which drives the hub generator to generate electricity through the braking process of the vehicle, and converts the kinetic energy of braking converted into electrical energy for recycling. [0003] For example, the publication number is CN103051108A, and the title is "Disc Excited Multi-pole Brushless S...
