Description

technical field

[0001] The invention relates to a split type electric wheel system, in particular to a split type electric wheel system with a non-excitation electromagnetic parking brake device which can be applied to a hub motor. Background technique

[0002] With the gradual maturity and industrialization of hybrid electric vehicle technology, the hub motor technology that can be directly arranged in the rim to drive the wheel is also constantly developing and improving. At present, in-wheel motor technology is mainly in the stage of experiment and real vehicle verification, and the existing in-wheel motor technology mainly involves the improvement of motor performance and coordinated control with the whole vehicle, but does not involve the design and research of electric wheel parking brake system.

[0003] Large-scale industrial motors and machine tools use electromagnetic brakes to ensure timely parking and accurate braking during work. It is divided into excited elec...
