The invention relates to the technical field of engineering vehicles, in particular to a buffer assembly, a suspension mechanism and a vehicle. The buffering assembly comprises a first oil cylinder, a second oil cylinder and an energy accumulator, the end portion of the first end of the first oil cylinder is connected with the middle frame, and the end portion of the second end of the first oil cylinder is connected with the middle axle. The end part of the first end of the second oil cylinder is connected with the rear frame, and the end part of the second end of the second oil cylinder is connected with the rear axle; the energy accumulator is connected with the first oil cylinder and the second oil cylinder and used for enabling the pressure in the first oil cylinder and the pressure in the second oil cylinder to be the same. The energy accumulator can enable the pressure in the first oil cylinder to be the same as the pressure of hydraulic oil in the second oil cylinder, the middle axle and the rear axle can bear the same thrust from the buffer assembly, and therefore the balance performance of the suspension mechanism provided with the buffer assembly is enhanced. The buffering assembly serves as an elastic buffering element between the middle axle and the middle frame and between the rear axle and the rear frame, and has the advantages of being simple in structure, long in service life, low in maintenance cost and the like.

    本发明涉及工程车辆技术领域,尤其涉及一种缓冲组件、悬架机构和车辆。该缓冲组件包括第一油缸、第二油缸和蓄能器,第一油缸的第一端端部与中车架连接,第一油缸的第二端端部与中车桥连接;第二油缸的第一端端部与后车架连接,第二油缸的第二端端部与后车桥连接;蓄能器与第一油缸和第二油缸分别连接,用于使第一油缸和第二油缸内的压力相同。蓄能器能够使第一油缸内的压力和第二油缸内的液压油的压力相同,可以实现中车桥和后车桥受到来自缓冲组件相同的推力,从而增强了设有本发明的缓冲组件的悬架机构的平衡性能。通过该缓冲组件作为中车桥和中车架、以及后车桥和后车架之间的弹性缓冲元件,具有结构简单、寿命高、以及维修成本低等优点。
