The invention discloses an auxiliary frame and vehicle body mounting structure which comprises an auxiliary frame, a fixing assembly and a vehicle body, a bearing beam of the fixing assembly is arranged, the longitudinal bearing face of the bearing beam makes contact with the vehicle body, and the transverse bearing face of the bearing beam is connected with the vehicle body through a connecting piece. The stress of torque on the connecting piece is reduced in the longitudinal direction, the torque in the horizontal direction is limited through the longitudinal supporting face, the stability of the vehicle is improved, the strength requirement for the connecting piece is lowered, and in the long-time using process, the connecting structure of the auxiliary frame and the vehicle body is kept stable; and the problems of looseness and abnormal sound generation caused by a single supporting surface and a connecting area are avoided.
本发明公开了一种副车架与车身安装结构,包括副车架、固定总成和车身,通过设置固定总成的承托梁,依靠承托梁的纵向支承面与车身相接触,承托梁的横向支承面与车身通过连接件相连接,在使用时车辆窜动的过程中,在纵向方向上减少力矩对连接件的受力,并依靠纵向支承面对水平方向的力矩进行限制,提高车辆稳定性,降低了对连接件的强度要求,在长时间的使用过程中,为副车架及车身的连接结构保持稳定,避免单支承面及连接区域造成松动及产生异响的问题。
