The cleat structure is arranged on the left side and the right side of the middle of the front auxiliary frame and comprises cleat supports arranged on the tops of corresponding longitudinal beams of the front auxiliary frame up and down, and the lower ends of the cleat supports wrap the top faces of the corresponding longitudinal beams and are fixed to the top faces of swing arm supports on the outer sides of the longitudinal beams. The upper end of the cleat support is provided with a connecting hole channel which vertically extends and allows a connecting bolt connected with a vehicle body to penetrate through, the outer side of the hole wall of the connecting hole channel is broken in the height direction and exposed, the lower end opening of the connecting hole channel is in a closed state, and the upper end opening of the connecting hole channel is exposed out of the top face of the cleat support and is in an open state. And the connecting bolt is communicated with the crevasse of the connecting hole channel to form a separation notch for separating the connecting bolt when the vehicle collides. According to the front auxiliary frame, the connecting bolt can be easily separated from the cleat support when a vehicle is collided, the situation that the front auxiliary frame moves backwards and is embedded into a passenger compartment is avoided, and the life safety of a driver and passengers is protected.

    本发明涉及一种用于前副车架的羊角结构及前副车架,分别设置在前副车架的中部的左右两侧,包括上下设置在前副车架对应纵梁顶部的羊角支架,该羊角支架的下端包裹在对应纵梁的顶面以及固定在该纵梁外侧的摆臂支架的顶面上,而羊角支架的上端设置有竖向延伸并供与车身连接的连接螺栓穿设的连接孔道,该连接孔道的孔壁外侧沿高度方向破口并外露,且该连接孔道的下端口呈闭合状态,而上端口外露于羊角支架的顶面并呈开口状态,且与连接孔道的上述破口处相连通而形成供车辆碰撞时上述连接螺栓脱出的脱出缺口。本发明中能使车辆发生碰撞时连接螺栓易从羊角支架上脱出,避免前副车架后移而嵌入乘员舱中,保护了司乘人员的生命安全。
