Problems solved by technology

[0003] However, in the general wheel drive system, due to the introduction of drive motors, reducers and other components in the wheel / wheel, the unsprung mass of the vehicle is significantly increased, which directly affects the grounding of the wheel and the ride comfort of the vehicle body.
[0004] Patent 201110053093.0 mentions a structure and method for reducing the equivalent unsprung mass of the single-wishbone suspension wheel side electric drive system, but it is only applicable to non-steering wheels

Abstract

The invention discloses a speed reducing type electric drive system in an integrated McPherson hanger bracket wheel, wherein an electric motor housing is integrated with an McPherson hanger bracket lower swing arm, a speed reducing box housing is integrated with a steering knuckle, and a distribution mode that an electric motor deviates from the center of a wheel and is close to an elastic hinge of a lower swing arm is adopted. The speed reducing type electric drive system has the advantage that the vibration of the electric motor relative to a frame can be reduced when the wheel jumps, and has the characteristics of high integration degree and light weight due to adoption of an equivalent spring.

Description

technical field [0001] The invention belongs to the field of electric vehicle chassis and transmission, and in particular relates to an integrated McPherson suspension in-wheel deceleration electric drive system. Background technique [0002] At present, the main structural feature of the wheel-side electric drive system represented by electric wheels is that the drive motor is installed in or near the drive wheel, which has the advantages of short drive transmission chain, efficient transmission, and compact structure. At the same time, the torque of each driving wheel in the wheel drive system can be independently controlled. The wheel motor is not only the information unit of the car, but also the fast-response control execution unit, which is conducive to the realization of high-performance control functions that are difficult to achieve on traditional cars, thereby improving harsh conditions. Driving performance under road conditions. [0003] However, in the general w...
