The invention relates to the technical field of trailer suspension, in particular to an assembly type suspension device which comprises two suspension sets, a middle connecting rod is arranged between the two suspension sets, and each suspension set comprises suspension mounting plates mounted on the two sides of a vehicle beam and suspension side vertical plates detachably connected with the suspension mounting plates. A supporting piece, a spring steel plate support cylinder and a pull rod base are sequentially arranged between the two suspension side vertical plates from top to bottom, the pull rod base is located at the bottom ends of the suspension side vertical plates, a pull rod pin is arranged in the spring steel plate support cylinder, and the pull rod pin is connected with the middle connecting rod. The suspension welding structure is reasonable in design, the problems that when a vehicle is heavy-loaded, due to stress concentration and material damage caused by suspension welding of the lower wing plate of the vehicle beam, the suspension position is not welded, and the vehicle beam is broken can be well solved, the maintenance cost of the vehicle is reduced, and the service life of the vehicle is prolonged.

    本发明涉及挂车悬挂技术领域,具体是指一种装配式悬挂装置,包括两个悬挂组,两个悬挂组之间设有中间连接杆,每个悬挂组包括安装于车梁两侧的悬挂安装板和与悬挂安装板可拆卸连接的悬挂侧立板,两个所述悬挂侧立板之间从上到下依次设有支撑件、弹簧钢板支座筒和拉杆座,所述拉杆座位于悬挂侧立板的底端,所述弹簧钢板支座筒内设有拉杆销,所述拉杆销与中间连接杆相连接。本发明设计合理,能够很好的解决在车辆重载时因车梁下翼板因悬挂焊接带来的应力集中及材料损伤,造成悬挂处开焊、车梁断裂等问题,减少了车辆的维修成本,延长了车辆的使用寿命。
