The invention discloses a connecting mechanism for a control arm and an auxiliary frame. The connecting mechanism comprises a gear opening structure, a control arm bush and a stress rod. The gear opening structure is arranged on the auxiliary frame and comprises a pair of opening part plates; the gear opening structure is provided with a pair of kidney-shaped holes opposite to each other in a mirror image mode, and the kidney-shaped holes are located in the two opening part plates respectively. The control arm bushing is arranged at the front end of the control arm and is mounted between the two opening part plates; the stress rod penetrates through the control arm lining, the two ends of the stress rod are connected into the kidney-shaped holes, and when the vehicle is subjected to offset collision, the stress rod moves in the extending direction of the kidney-shaped holes. And the anti-skid surface of the elastic anti-skid axial limiting piece is tightly attached to the outer side surface of the open gear part plate, so that the friction force borne by the stress rod in the extension direction of the waist-shaped hole is enlarged. When a vehicle is subjected to offset collision, the stress rod slides along the extension direction of the waist-shaped hole in a friction manner, so that collision energy can be absorbed and buffered, the problem that a wheel edge part is completely out of control due to direct separation of the control arm and the auxiliary frame is avoided, and the passive safety of collision is improved.
本发明公开了一种控制臂与副车架连接机构,包括开档结构、控制臂衬套和受力杆;开档结构设于副车架上,包括一对开档零件板;开档结构设有一对镜像相对的腰型孔,该对腰型孔分别位于两开档零件板上;控制臂衬套设于控制臂前端,安装于两开档零件板之间;受力杆贯穿控制臂衬套、且两端连接在腰型孔内,车辆受到偏置碰撞时,受力杆沿腰型孔的延伸方向运动。还包括弹性防滑轴向限位片,弹性防滑轴向限位片的防滑面紧贴开档零件板外侧面,提高受力杆在腰型孔延伸方向上所受的摩擦力。车辆受到偏置碰撞时,受力杆沿腰型孔延伸方向摩擦滑动,能吸收、缓冲碰撞能量,避免控制臂与副车架直接分离造成轮边部分完全失控的问题,提高了碰撞被动安全性。
