The invention discloses a front suspension assembly of a vehicle, an auxiliary frame assembly and the vehicle, the front suspension assembly comprises a suspension support, a front suspension structure, a connecting piece and a cutting piece, the suspension support is provided with a mounting cavity, and each of the opposite side walls of the mounting cavity is provided with a first mounting hole and a mounting sliding groove communicating with the first mounting hole; a part of the front suspension structure is arranged in the mounting cavity; the connecting piece is connected with the front suspension structure and is matched with the first mounting hole to fix the front suspension structure on the suspension bracket; and a cutting piece is arranged at each mounting sliding groove, the connecting pieces drive the front suspension structures to slide from the first mounting holes to the mounting sliding grooves when the vehicle collides, and the cutting pieces make contact with the connecting pieces located in the mounting grooves so as to at least cut off the connecting pieces. Due to the fact that the front suspension structure and the suspension support are thoroughly separated, the front suspension structure sinks, the front suspension structure and the engine are staggered, the front suspension structure takes away impact energy and cannot transmit the impact energy to the engine, and the engine is prevented from invading a passenger compartment.
本发明公开了一种车辆的前悬置总成、副车架总成和车辆,前悬置总成包括悬置支架、前悬置结构、连接件和切割件,悬置支架具有安装腔,安装腔的相对侧壁中每个侧壁均开设有第一安装孔和与第一安装孔连通的安装滑槽;前悬置结构的部分设于安装腔;连接件与前悬置结构相连且与第一安装孔配合以将前悬置结构固定于悬置支架;每个安装滑槽处均设有切割件,车辆发生碰撞时连接件带动前悬置结构从第一安装孔滑向安装滑槽,切割件与位于安装槽内的连接件接触,以至少将连接件切断。由此前悬置结构与悬置支架彻底分离,前悬置结构下沉,前悬置结构与发动机产生错位,前悬置结构将撞击能量带走而不会传递到发动机上,避免发动机侵入乘员舱。
