The invention provides a duplex bridge suspension which comprises a longitudinal beam, a plurality of cross beams are arranged on the longitudinal beam at intervals, a plurality of transverse thrust rods are arranged on the longitudinal beam, balance beams are symmetrically arranged at one end of the longitudinal beam and on the outer side of the longitudinal beam, and spiral springs are connected to the lower portions of the two sides of each balance beam. The lower portion of the spiral spring on one side is connected with an axle upper support arranged on the upper portion of the axle, the lower portion of the spiral spring on the other side is connected with an axle upper support arranged on the upper portion of the axle, an axle guide arm is arranged on one side of the axle and on the longitudinal beam, and an axle guide arm is arranged on the other side of the axle and on the longitudinal beam. By means of the duplex bridge structure, axle vibration caused when a vehicle is impacted can be effectively reduced, the situation that the vehicle is impacted to influence vehicle running and the vehicle is damaged due to the fact that the axle collides with a longitudinal beam is avoided, and the impact borne in the vehicle running process can be absorbed and relieved through cooperation of all the mechanisms so that stable running of the vehicle can be guaranteed.

    本发明提供一种双联桥悬架,包括纵梁,所述纵梁上间隔设置有多个横梁,所述纵梁上设置有若干个横向推力杆,所述纵梁的一端且在纵梁的外侧对称设置有均衡梁,所述均衡梁的两侧下部连接有螺旋弹簧,其中一侧螺旋弹簧的下部与设置在车桥上部的车桥上支座连接,另一侧螺旋弹簧的下部与设置在车桥上部的车桥上支座连接,所述车桥的一侧且在纵梁上设置有车桥导向臂,所述车桥的一侧且在纵梁上设置有车桥导向臂,可以通过双联桥结构有效减小车辆受到冲击时造成的车桥震颤避免车桥受到冲击影响车辆行驶,以及造成车桥碰撞纵梁造成车辆损伤,且能通过各个机构配合将车辆行驶过程中受到的冲击进行吸收减缓保证车辆的稳定行驶。
