The invention relates to the technical field of suspensions, and provides a trailing arm suspension with a Watt connecting rod and an automobile, the trailing arm suspension with the Watt connecting rod comprises the Watt connecting rod, the Watt connecting rod comprises a rocker arm, a left pull rod and a right pull rod, and the middle of the rocker arm is connected with an axle through a revolute pair; one end of the left pull rod is connected with one end of the rocker arm through a revolute pair, and the other end is connected with the left side of the vehicle body through a revolute pair; one end of the right pull rod is connected with the other end of the rocker arm through a revolute pair, and the other end is connected with the right side of the vehicle body through a revolute pair. Transverse movement of the rear axle is limited to the maximum extent, drifting of the vehicle is prevented, the posture of the vehicle body can be well controlled, excessive side tipping of the vehicle body is avoided, compared with the prior art, the torsional rigidity of the rear suspension cannot be increased, the risk of excessive steering is avoided, and the safety of the vehicle is improved. And meanwhile, the too strong pulling and shaking feeling to the vehicle body caused by the ground beating feeling of vehicle tires is avoided.
本发明涉及悬架技术领域,本发明提供了一种具有瓦特连杆的拖曳臂悬架及汽车,具有瓦特连杆的拖曳臂悬架包括瓦特连杆,瓦特连杆包括摇臂、左拉杆和右拉杆,摇臂的中部与车轴通过转动副连接;左拉杆的一端与摇臂的一端通过转动副连接,左拉杆的另一端与车身左侧通过转动副连接;右拉杆的一端与摇臂的另一端通过转动副连接,右拉杆的另一端与车身右侧通过转动副连接。本发明不但最大限度限制了后轴的横向运动,防止车辆甩尾,还可以很好地控制车身姿态,避免车身过度侧倾,而且与现有技术相比,不会增加后悬的扭转刚度,避免导致过度转向的风险,同时避免车辆轮胎拍地感导致对车身的拉扯晃动感太强。
