The invention discloses a front sub-frame assembly and a vehicle. The front sub-frame assembly comprises at least one frame cross beam, a front sub-frame and a rear sub-frame, the vehicle frame comprises a vehicle frame cross beam, a lower swing arm and two vehicle frame longitudinal beams, the two vehicle frame longitudinal beams are connected to the two ends of the vehicle frame cross beam in a spaced mode, at least part of each vehicle frame longitudinal beam is constructed to be an inclined section, the inclined section is constructed to obliquely extend outwards from back to front, and the front end of the inner side of the lower swing arm is movably connected with the inclined section through a breakable connecting piece; the rear end of the inner side of the lower swing arm is movably connected with a frame longitudinal beam, and the outer side of the lower swing arm is suitable for being fixed relative to a wheel; during collision, collision force on the inclined section is suitable for acting on the breakable connecting piece and enabling the breakable connecting piece to be broken, so that the outer side of the lower swing arm moves backwards in an arc mode relative to the rear end of the inner side of the lower swing arm. According to the front auxiliary frame assembly provided by the embodiment of the invention, when the vehicle is collided, the breakable connecting piece can be broken to release part of impact force, so that other structures can be protected, and the safety strategy of vehicle collision is improved.
本发明公开了一种前副车架总成和车辆,前副车架总成包括:至少一个车架横梁;下摆臂和两个车架纵梁,两个车架纵梁间隔开连接于车架横梁的两端,每个车架纵梁的至少部分构造为倾斜段,倾斜段构造为从后往前朝外倾斜延伸,下摆臂的内侧前端与倾斜段通过可断裂连接件可活动地相连,下摆臂的内侧后端与车架纵梁可活动地相连,下摆臂的外侧适于与车轮相对固定;其中,在碰撞时,倾斜段上的碰撞力适于作用于可断裂连接件且使可断裂连接件发生断裂以使下摆臂的外侧相对于下摆臂的内侧后端朝后呈弧线运动。本发明实施例的前副车架总成,在车辆发生碰撞时,可使可断裂连接件发生断裂以释放部分冲击力,进而可对其它结构进行保护,提高车辆碰撞的安全策略。
