The invention relates to a suspension swing arm assembly and an automobile thereof. The suspension swing arm assembly comprises a front arm, a rear arm, a swing arm shaft, a ball pin assembly, a frontthreaded cylinder, a rear threaded cylinder and a rubber layer. The rubber layer is vulcanized on the outer circular walls of the front threaded cylinder and the rear threaded cylinder, the rubber layer and the front threaded cylinder are pressed in the front arm together, and the rubber layer and the rear threaded cylinder are pressed in the rear arm together; one end of the swing arm shaft is connected with the front threaded cylinder, and the other end of the swing arm shaft is connected with the rear threaded cylinder; the front arm, the ball pin assembly and the rear arm are fixed together through bolts and nuts. According to the suspension swing arm assembly, the outer trapezoidal threads of the swing arm shaft are connected with the inner trapezoidal threads of the front threaded cylinder and the inner trapezoidal threads of the rear threaded cylinder, when the swing arm rotates around the center line of the swing arm shaft, rotation and transmission are achieved through connection of the trapezoidal threads, the swing arm is driven to move front and back, and therefore the smoothness of suspension movement and the control stability of the whole vehicle are improved.

    本发明涉及一种悬架摆臂总成及其汽车,包括前臂、后臂、摆臂轴、球销组件、前螺纹圆筒、后螺纹圆筒及橡胶层;橡胶层硫化在前螺纹圆筒和后螺纹圆筒外圆壁上,橡胶层与前螺纹圆筒一起压装于前臂内,橡胶层与后螺纹圆筒一起压装于后臂内;摆臂轴的一端与前螺纹圆筒连接,摆臂轴的另一端与后螺纹圆筒连接;螺栓螺母将前臂、球销组件和后臂固定在一起。本发明的技术方案通过摆臂轴的外梯形螺纹与前螺纹圆筒和后螺纹圆筒的内梯形螺纹连接,当摆臂绕摆臂轴中心线转动时,通过梯形螺纹的连接实现转动和传动,带动摆臂前后运动,这样提高了悬架运动的平顺性和整车的操纵稳定性。
