The invention discloses a rear suspension structure capable of adjusting vertical force of wheels, which comprises a suspension assembly and an actuating mechanism connected with the suspension assembly, the actuating mechanism comprises a motor, a speed reducer, a push-pull rod and a rocker arm, the motor is connected with the speed reducer, the speed reducer is connected with the rocker arm, and the push-pull rod is connected with the rocker arm. One end of the push-pull rod is connected with the rocker arm, and the other end of the push-pull rod is connected with the suspension assembly. According to the rear suspension structure, by changing the torque output of the motor, the vertical force output of the left wheel and the right wheel of the rear suspension can be independently controlled, mutual conversion between the torque (rotational motion) of the motor and the approximate vertical force (linear motion) between the sprung mass and the unsprung mass is achieved, and the running smoothness and the handling stability of the whole vehicle are improved. The invention further provides an automobile with the rear suspension structure capable of adjusting the vertical force of the wheels.

    本发明公开了一种能够调整车轮垂向力的后悬架结构,包括悬架总成以及与所述悬架总成连接的作动机构,所述作动机构包括电机、减速器、推拉杆及摇臂,所述电机与所述减速器连接,所述减速器与所述摇臂连接,所述推拉杆的一端与所述摇臂连接,另一端与所述悬架总成连接。本发明提供的后悬架结构,通过改变电机的转矩输出,可单独控制后悬架左右车轮垂向力输出,实现电机的转矩(旋转运动)和簧上质量与簧下质量之间近似的垂向力(直线运动)的相互转化,提升整车行驶的平顺性和操纵稳定性。本发明还提供了一种具有该能调整车轮垂向力的后悬架结构的汽车。
