Abstract

The invention discloses a hub motor, which comprises a hub assembly, a motor assembly, a reducer assembly, an output assembly and a braking assembly. The hub assembly includes a rigid hub and a braking hub, the rigid hub divides an internal space of a wheel into an internal chamber and an external chamber, the motor assembly and the reducer assembly are installed in the internal chamber, the output assembly comprises a central shaft arranged on the rigid hub in a penetrating mode, the braking hub sleeves a central shaft and is located in the external chamber to act as a braking chuck, and thebraking assembly is installed in the external chamber to brake the braking hub. According to the hub motor, motor vibration can be reduced, and thus the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an in-wheel motor and an electric automobile. Background technique [0002] With the increasing awareness of environmental protection in countries all over the world, the application of electric vehicles has also received more and more attention. As the driving part of electric vehicles, the importance of in-wheel motors can be imagined. A high-efficiency, long-life, and high-stability in-wheel motor is the key to the comfort and durability of an electric vehicle. A good working environment of the hub motor is the key to its life and efficiency. The invention proposes structural optimization for the hub motor and provides a stable and safe working environment for the motor. [0003] In-wheel motor technology, also known as in-wheel motor technology, integrates power, transmission and braking devices into the wheel hub, which will simplify the mechanical space o...
