The invention discloses trailer energy absorption equipment, and belongs to the technical field of energy absorption, the trailer energy absorption equipment comprises a base body, a plurality of supporting plates and connecting pieces, the base body is used for being fixed with a trailer frame, the supporting plates are installed in the length direction of the base body, the distance between the supporting plates and the base body is adjustable, and the connecting pieces are used for connecting the supporting plates. Inserting rods are fixed to the supporting plates, and a plurality of oil pressure buffering bodies corresponding to the supporting plates one to one are arranged in the base body. Due to the design of the oil pressure buffering body, hydraulic oil can flow between different oil columns and buffering holes during collision, and therefore impact force is absorbed and dispersed. In addition, a buffering unit is further arranged in the oil pressure buffering body and comprises a first piston column, a second piston column and a first elastic body connected with the first piston column and the second piston column. The middle of the first oil column further communicates with an oil injection pipe, and hydraulic oil can be conveniently injected into or supplemented into the oil pressure buffering body. And a sliding groove matched with the sliding block is formed in the base body, the end, away from the sliding column, of the sliding block is connected with a second elastic body, and the energy absorption effect of the equipment is further improved.
本发明公开了一种挂车吸能设备,属于吸能技术领域,包括基体、多个支板和连接件,其中基体用于与挂车车架固定,支板沿着基体的长度方向安装,且距离基体的距离为可调距离,连接件用于将多个支板连接。支板上固定有插杆,基体的内部设有多个与支板一一对应的油压缓冲体。油压缓冲体的设计使得在碰撞时,液压油能够在不同的油柱和缓冲孔之间流动,从而吸收和分散冲击力。此外,油压缓冲体内部还设置了缓冲单元,包括第一活塞柱和第二活塞柱,以及连接它们的第一弹性体。第一油柱的中部还连通有注油管,便于向油压缓冲体内注入或补充液压油。基体上开设有与滑块适配的滑槽,滑块远离滑柱的一端连接有第二弹性体,进一步提高了设备的吸能效果。
