The invention discloses a suspension assembly of a trailer and the trailer. The suspension assembly of the trailer comprises a bracket, a middle bracket, a connecting bracket, a balance beam, an axle, a steel plate spring and a connecting rod, the support, the middle support and the connecting support are all fixed to a frame of the trailer, and the connecting support is located between the middle support and the support. The middle of the balance beam is pivoted to the middle support, and one end of the balance beam forms a swing end. The axle is fixed to the middle of the steel plate spring, one end of the steel plate spring is connected to the support, and the other end of the steel plate spring is connected to the swing end of the balance beam in a penetrating mode and matched with the swing end of the balance beam in an up-down floating mode. One end of the connecting rod is hinged to the axle, the other end of the connecting rod is hinged to the connecting support, the upper surface of the connecting rod forms a limiting face, a frame of the trailer is provided with a limiting part, and the swing end swings between the limiting face and the limiting part. The swing amplitude of the balance beam is reduced, the steel plate spring is prevented from being separated from the swing end of the balance beam, the length of the connecting rod is shortened, and the connecting rod is not prone to deformation.

    本发明公开了一种挂车的悬挂总成及挂车,挂车的悬挂总成包括支架、中支架、连接支架、平衡梁、车轴、钢板弹簧、连杆;支架、中支架、连接支架均固定在挂车的车架上,连接支架位于中支架和支架之间;平衡梁的中部枢接在中支架上,其一端形成摆动端;车轴固定在钢板弹簧的中部,钢板弹簧的一端连接在支架上、另一端穿接于平衡梁的摆动端,钢板弹簧的另一端与平衡梁的摆动端上下浮动的配合;连杆的一端与车轴铰接、另一端铰接于连接支架上,连杆的上表面形成限位面,挂车的车架上设置有限位部,摆动端在限位面和限位部之间摆动。本发明减小了平衡梁的摆动幅度,避免钢板弹簧从平衡梁的摆动端脱离,缩短的连杆的长度,使连杆不易发生变形。
