Dismountable hub motor of DC electric vehicle

Abstract

The invention discloses a dismountable hub motor of a DC electric vehicle. The dismountable hub motor comprises a stator and a rotor; the rotor comprises a side cover plate, a magnetic steel and an end cover; the end cover comprises a side plate part and a cylinder part; the side plate part is fixed to one end of the cylinder part; the magnetic steel is mounted in the cylinder part; the side cover plate is rotatably mounted on a motor shaft; a cored winding is positioned in the cylinder part and matched with the magnetic steel; the side cover plate is fixedly connected with the other end of the cylinder part; the motor shaft extends from the inner part of the cylinder part to pass through the side plate part. The dismountable hub motor further comprises an independent hub; a mounting hole of the hub sleeves the outer part of the cylinder part and is detachably fixed to the rotor; a valve hole is formed in the hub; a valve through hole correspondingly matched with the valve hole is formed in the side cover plate. With the adoption of the dismountable hub motor, inner and outer tires can be easily dismounted; dismounting and adhering the magnetic steel again are saved during replacing a deformed hub, and thus the resulting unnecessary loss and trouble are avoided, and the whole hub replacement process is easy, fast and efficient.

Description

technical field [0001] The invention relates to a hub motor, in particular to a detachable hub motor of a DC electric vehicle. Background technique [0002] The motor of an existing DC electric vehicle is generally composed of a rotor and a stator. The rotor is composed of a hub, a magnetic steel, an end cover, a bearing and an oil seal, and the stator is composed of an iron core winding, a motor shaft, a power line, a Hall and a circuit board. [0003] If the integrated wheel hub motor has tire wear, puncture or wheel hub deformation during use, the entire motor must be disassembled from the electric vehicle. If the tire is worn or punctured, the original old The tires are removed and replaced with new tires, and then the motor is assembled on the vehicle. This operation will cause trouble in after-sales maintenance and low work efficiency. [0004] If the hub is deformed, the entire motor must be removed, the deformed hub must be replaced, and the magnetic steel on the hu...

Problems solved by technology

In this way, the maintenance method of directly replacing the motor with the deformation of the hub virtually increases the maintenance cost of the user, and is a waste of resources.
