Abstract

The invention provides an external rotor hub motor driving assembly. The external rotor hub motor driving assembly comprises a hub, a motor and a brake, wherein the motor is installed in the hub, andthe motor comprises a rotor assembly and a stator assembly; the rotor assembly is arranged outside the stator assembly; the stator assembly is connected with the power supply to drive the rotor assembly to drive the hub to rotate; the motor is further connected with the brake, and the rotor assembly is braked to enable the hub to stop rotating through the brake. The cooling structure and the supporting structure of the hub motor assembly are both integrated in the hub, so that the structure size of the motor is greatly shortened, and the cooling performance is high; two bearings are adopted for supporting the rotor assembly and the stator assembly, so that the positioning precision is high, and the structure is more reliable; and meanwhile, the structure of the driving assembly is simplified, the universality is high, and the arrangement requirements of various vehicle types on the driving assembly can be met. In addition, a brake disc is directly fixedly connected with the rotor assembly, so that the brake performance is better, and the reliability is higher.

Description

technical field [0001] The invention relates to an outer rotor hub motor drive assembly. Background technique [0002] With the development of the transportation industry and the improvement of people's economic level, automobiles have become an indispensable means of transportation for people's daily life. However, the huge number of fuel vehicles consume a huge amount of limited oil resources on the one hand, and on the other hand, it will also lead to aggravated environmental pollution. In order to develop a green and environmentally friendly economy and alleviate the increasingly serious environmental problems, electric vehicles that do not consume oil resources and are clean and pollution-free are the first choice for travel. For electric vehicles, the electric drive system is a core key technology that determines their driving performance. Compared with traditional fuel vehicles, new energy vehicles have undergone tremendous changes in both the general layout of the ...
