The invention relates to the field of automobile chassis and safe collision, in particular to a pickup truck frame assembly for improving the collision safety performance of a whole truck. Specifically, on the basis of a two-longitudinal-beam and seven-cross-beam structure of a traditional pickup truck frame, the newly-added front limiting arm can reduce the collision contact area and the borne load of a truck body doorsill beam, the newly-added rear limiting arm limits the steering angle of a front wheel, the situation that an upper truck body is pressed due to the fact that the steering angle of the wheels is too large is avoided, and meanwhile the load borne by the truck body doorsill beam is divided; and the rigidity of the rear part of the frame is increased by the cross beam inclined supporting arms. The anti-collision device is applied to a certain pickup truck type, can meet the excellent requirements for safe collision of C-NCAP five stars and C-IASI, greatly improves the safety performance of the whole vehicle, and provides better guarantee for life and property safety of vehicle drivers and passengers.
本发明涉及汽车底盘、安全碰撞领域,具体涉及一种提升整车碰撞安全性能的皮卡车架总成。具体在皮卡传统车架两纵梁、七横梁结构基础上,新增前限位臂可以减少车身门槛梁碰撞接触面积及所受载荷、新增后限位臂限制前轮转向角度,防止车轮转向角度过大压迫上车体,同时对车身门槛梁所受载荷进行分载,降低碰撞时上车体承受的冲击力和横梁斜撑臂增加车架后部刚度。应用于某皮卡车型,可满足安全碰撞C‑NCAP五星以及C‑IASI优秀要求,较大的提升了整车安全性能,为车辆驾驶员及乘客的生命财产安全提供更好的保障。
