Abstract

The invention discloses a split electric wheel system with a thin excitation-free electromagnetic parking braking device. The split electric wheel system is applied to a wheel hub motor, aims to solve the problem of complex structure of the existing electric wheel vehicle braking system, and comprises a wheel, the wheel hub motor, a brake disc, a motor shell crossover flange, an electromagnetic brake, a suspension beam end part and a sleeve, wherein the suspension beam end part, the electromagnetic brake, the motor shell crossover flange, the brake disc, the wheel hub motor and the wheel are sleeved on a motor shaft in sequence, the sleeve is hollowly sleeved on the motor shaft and is located between the motor shaft and the motor shell crossover flange, one end of the sleeve is in contact with the flange of the suspension beam end part, the other end of the sleeve is in contact with the shaft shoulder of the motor shaft, the wheel and a shell on the outer side of the wheel hub motor are fixedly connected by rim bolts, the motor shell crossover flange, the brake disc and a shell on the inner side of the wheel hub motor are fixedly connected in sequence by brake disc bolts, one end of the electromagnetic brake is in splined joint with the motor shell crossover flange, and the other end of the electromagnetic brake is sleeved on the flange of the suspension beam end part.

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...
