The invention relates to the technical field of trailer suspensions, in particular to an automatic lifting trailer suspension system which comprises an axle, an upper cross arm, a lower cross arm and a supporting plate, one end of the upper cross arm and one end of the lower cross arm are hinged to the axle, the other end of the upper cross arm and the other end of the lower cross arm are hinged to the supporting plate, and a connecting plate is connected to the axle. The damping system comprises a fixing shaft, a lifting sliding sleeve is connected to the fixing shaft in a sliding mode, the sliding block and the lifting sliding block are connected through a driving connecting rod, and a damping spring bears impact force generated by the suspension system and the supporting plate for damping. And meanwhile, a sliding block is driven to slide on a horizontal shaft through extension and contraction of a bidirectional hydraulic rod, the sliding block drives a lifting sliding block and a supporting plate to move up and down through a driving connecting rod, the height of the suspension system is automatically adjusted, the balance of the trailer is kept when the trailer passes through a pit, stress does not need to be conducted through a threaded structure, and the service life is longer.
本发明涉及挂车悬架技术领域,具体的是一种自动升降的挂车用悬架系统,本发明包括车轴、上横臂、下横臂和支撑板,所述上横臂和下横臂的一端均和车轴铰接、另一端和支撑板铰接,所述车轴上连接有连接板,连接板上设置有减震系统和升降系统所述减震系统包括固定轴,固定轴上滑动连接有升降滑套,滑动块和升降滑块之间通过驱动连杆进行连接,由减震弹簧承受悬挂系统和支撑板产生的冲击力进行减震,同时通过双向液压杆伸展和收缩带动滑动块在水平轴上滑动,滑动块通过驱动连杆带动升降滑块以及支撑板上下移动,对悬挂系统的高度进行自动调整,使得在挂车经过凹坑时保持挂车的平衡,无需通过螺纹结构进行受力,使用寿命更长。
