Abstract

The present invention provides a rotor assembly, a motor and a vehicle, the rotor assembly comprises: a rotor shaft, one end of which is provided with a positioning boss; a rotor core assembly, sleeved on the rotor shaft; a first rotor baffle, wherein the first rotor baffle is sleeved on the rotor shaft, and the rotor core assembly is disposed between a positioning convex platform and the first rotor baffle; wherein the rotor shaft is provided with a first positioning portion, and the first rotor baffle is provided with a second positioning portion that cooperates with the first positioning portion, the first positioning portion abuts the second positioning portion to enable the rotor shaft to perform axial positioning to the first rotor baffle. The technical solution can solve the technical problem that the rotor core assembly of the prior art is easy to loosening during operation.

Description

technical field [0001] The invention relates to the technical field of motors, in particular, to a rotor assembly, a motor and a vehicle. Background technique [0002] At present, with the continuous development of the automobile industry, the attention to energy and the demand for new energy vehicles are also becoming stronger. Under the changing trend of electrification, intelligence, light weight and sharing, it is particularly important to improve the performance of automobile motors. In the prior art, power steering is generally used to reduce the strength of turning the steering wheel, reduce driver fatigue, and improve driving safety. Power steering is to assist the driver to adjust the direction of the car. The difference between electro-hydraulic power assist and mechanical power assist is that motor drive replaces engine drive. With the gradual development of new energy sources, motor drive will replace the engine and become the core component of the car. [000...
