The invention discloses an electric vehicle suspension structure and a vehicle comprising the suspension structure. The suspension structure comprises an upper rocker arm and an upper rocker arm support connected with the upper rocker arm and a vehicle frame. The lower rocker arm is connected with the lower rocker arm and the lower rocker arm support of the frame; a hub reduction gear and a hub motor; the hub motor is located between the upper rocker arm and the lower rocker arm. And the upper ball head support welding part and the lower ball head support welding part are respectively arranged on the electric wheel set assembly through bolts. And the rocker arm upper supporting seat and the rocker arm lower supporting seat are respectively welded with a longitudinal beam at the bottom of the frame to form an integral structure. In order to achieve integrated installation of the motor and the wheel edge, the lower rocker arm support is designed to be of a bent structure, meanwhile, an upper ball head supporting seat and a lower ball head supporting seat on the electric wheel set assembly are designed to be of structures extending towards the upper portion and the lower portion of the center line of the axle respectively, on one hand, installation space can be reserved for the motor, and on the other hand, the length of an upper rocker arm and the length of a lower rocker arm can be shortened. The rigidity is enhanced.
本发明公开了一种电动汽车悬架结构及包含该悬架结构的车辆,所述悬架结构包括上摇臂、连接上摇臂和车架的上摇臂支座;下摇臂,连接下摇臂和车架的下摇臂支座;轮边减速器和轮毂电机;所述轮毂电机位于上摇臂和下摇臂之间。所述上球头支座焊合、下球头支座焊合分别通过螺栓安装于电动轮组总成上。所述摇臂上支撑座、摇臂下支撑座分别与车架底部纵梁焊接,形成整体结构。为实现电机与轮边的集成安装,下摇臂支撑设计成折弯结构,同时将电动轮组总成上的上球头支撑座和下球头支撑座分别设计成向车桥中心线的上下方延伸的结构,一方面能够为电机预留安装空间,另一方面能够缩短上下摇臂的长度,增强刚度。
