The invention provides a front cross beam of a rear auxiliary frame. The front cross beam comprises a front cross beam body, a cavity extending in the width direction of the vehicle is formed in the front cross beam body, the size of the front cross beam body in the height direction of the vehicle is gradually decreased from the middle section to the two ends in the width direction of the vehicle,and the size of the front cross beam body in the length direction of the vehicle is gradually increased; wherein the two bushing outer pipe mounting parts are arranged at the two ends of the front cross beam body respectively, and the two suspension sleeve mounting parts are arranged in the middle of the front cross beam body. According to the front cross beam of the rear auxiliary frame, the front cross beam body is conveniently connected with a longitudinal beam through the matched change of the size of the front cross beam body in the height direction and the length direction of a vehicle,the rigidity of the front cross beam body can be guaranteed, and the total weight is effectively reduced while the rigidity is guaranteed.

    本发明提供了一种后副车架前横梁,包括前横梁本体,于前横梁本体内部构造有沿着车辆宽度方向延伸设置的空腔,且由车辆宽度方向的中段至两端,前横梁本体沿车辆高度方向的尺寸逐渐减小,前横梁本体沿车辆长度方向的尺寸逐渐增大;还包括被分别配置于前横梁本体两端的两个衬套外管安装部,以及被配置于前横梁本体中部的两个悬置套管安装部。本发明所述的后副车架前横梁,通过前横梁本体沿车辆高度方向和长度方向尺寸的配合变化,不仅与纵梁连接方便,还可保证自身的刚度,并在保证刚度的同时有效减轻总重。
