An independent suspension integrated wheel-side motor assembly is mainly used for manufacturing pure electric vehicles. A disconnected suspension structure is adopted, and suspensions on the left sideand the right side are independently connected with a vehicle frame, so independence during vertical jumping of a left wheel end and a right wheel end is achieved; a motor is installed on a stand column and does not rotate along with a knuckle; a two-section type main pin and a coaxial speed reducer structure are adopted, so a space is provided for arrangement and power transmission of the motor.The motor, the wheel ends and the independent suspension structure are integrated, a traditional transmission shaft and variable box structure is omitted, and due to the fact that the suspension is of an independent suspension structure, the unsprung mass can be reduced to a large extent, so the system is simplified, the assembly weight is reduced, the light-weight target is achieved, and the whole vehicle control stability and smoothness are greatly improved.
一种独立悬架集成轮边电机总成,主要用于纯电动汽车制造。采用断开式悬架结构,左、右两边的悬架单独与车架连接,实现左、右轮端上下跳动时的独立性;电机安装于立柱上,不随转向节转动;采用两段式主销和同轴减速器结构,为电机的布置和动力传输提供了空间。本发明将电机、轮端、独立悬架结构进行集成,取消了传统的传动轴与变数箱结构,且由于悬架采用独立悬架结构,能够很大程度的减少非簧载质量,使系统得到了简化,减少了总成重量,实现了轻量化目标,整车操纵稳定性、平顺性都得到大幅度提高。
