The invention discloses an electric vehicle suspension and an electric vehicle. The electric vehicle suspension includes: a hub motor disposed on an inner side of a rim; one end of the first spring and damper assembly is mechanically connected with the hub motor; the first spring and the other end of the damper assembly are connected with a vehicle body; the at least two battery tuned mass dampers are located on the two sides of the vehicle body and located above the wheels; one end of the battery tuned mass damper is mechanically connected with the unsprung part of the vehicle, and the other end of the battery tuned mass damper is connected with the vehicle body. According to the suspension structure, vibration of the unsprung structure can be restrained, the vibration amplitude of the unsprung structure is reduced, the influence caused by increase of the unsprung mass of the vehicle due to vehicle bumping is reduced, the vertical dynamic performance, the driving comfort and the road operability of the vehicle are improved, and the dynamic load of vehicle tires is reduced.

    本发明公开了一种电动车辆悬架及电动汽车。该电动车辆悬架包括:轮毂电机,所述轮毂电机设置于轮辋的内侧;第一弹簧和阻尼器组件,所述第一弹簧和阻尼器组件的一端与所述轮毂电机机械连接;所述第一弹簧和阻尼器组件的另一端与车体连接;至少两个电池调谐质量阻尼器,所述电池调谐质量阻尼器位于所述车体的两侧,且位于车轮的上方;所述电池调谐质量阻尼器的一端与车辆簧下部分机械连接,所述电池调谐质量阻尼器的另一端与所述车体连接。本实施例提出的悬架结构可以抑制簧下结构振动,减小簧下结构的振动幅度,减小车辆颠簸降低车辆非簧载质量增加带来的影响,提高车辆的垂直动态性能、驾乘舒适性以及道路操作性,降低车辆轮胎的动载荷。
