The invention discloses an electric automobile chassis integrated system which comprises a hub motor and an electric control air suspension, the electric control air suspension comprises an elastic piece arranged on the inner side of a hub, one end of the elastic piece is movably connected with a middle support, the other end of the elastic piece is movably connected with a side support, and the side support is connected with a rear end cover of the hub motor. A telescopic piece connected with the middle support is arranged on one side of the middle support, and the distance between wheels on the left side and the right side of the vehicle is changed by controlling the length of the telescopic piece; in the invention, when the vehicle is in high-speed steering, the lengths of the elastic piece and the telescopic piece are controlled, the wheel track of the vehicle is increased, the safety of the vehicle during steering is improved, and the problem of rollover of the vehicle is avoided; the rigidity or damping of the elastic piece can be adjusted in real time to adapt to different road surfaces, so that the automobile can obtain good smoothness and road friendliness in the running process; meanwhile, the two elastic pieces control the lengths of the elastic pieces to adjust the height of the automobile body, the height of the automobile body is changed, and the trafficability of the automobile can be improved.
本发明公开了一种电动汽车底盘集成系统,包括轮毂电机和电控空气悬架,所述电控空气悬架包括设于轮毂内侧的弹性件,弹性件一端与中支架活动连接,另一端与侧支架活动连接,所述侧支架与轮毂电机的后端盖连接,所述中支架一侧设有与其连接伸缩件,通过控制所述伸缩件的长度改变车辆左右两侧车轮的轮距;本发明中,当车辆处于高速转向时,控制弹性件和伸缩件长度,增大车辆轮距,提高车辆转向时的安全性,避免车辆出现侧翻的问题;且弹性件可实时调节刚度或阻尼,适应不同路面,使汽车在运行中能获得良好的平顺性和道路友好性;同时,两个弹性件通过控制各自的长度实现车身高度调节,改变汽车的车身高度,可提高汽车的通过性。
