The invention discloses a front auxiliary frame assembly and a vehicle, the front auxiliary frame assembly comprises a frame longitudinal beam and a lower swing arm, at least part of the frame longitudinal beam is constructed to be an inclined section, and the inclined section is constructed to obliquely extend outwards from back to front; the front end of the inner side of the lower swing arm is connected with the inclined section through a first connecting piece, a rear support is arranged at the rear end of the inner side of the lower swing arm and connected with the frame longitudinal beam through a second connecting piece, and the outer side of the lower swing arm is connected with the wheel. The inclined section is suitable for acting on the first connecting piece and enabling the first connecting piece to be broken during collision, and the first connecting piece is arranged to be broken before the second connecting piece during collision. According to the front auxiliary frame assembly, when the first connecting piece is broken, the front end of the inner side of the lower swing arm is separated from the first connecting piece so as to be thrown out towards the outer side, and the rear end of the inner side of the lower swing arm is always kept connected with the frame longitudinal beam, so that the front end of the inner side of the lower swing arm is thrown out moderately, and the situation that wheels move towards the inner side of the vehicle to threaten people in the vehicle is prevented.

    本发明公开了一种前副车架组件及车辆,前副车架组件包括:车架纵梁和下摆臂,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第一连接件相连,下摆臂的内侧后端设有后部支架,后部支架与车架纵梁通过第二连接件相连,下摆臂的外侧与车轮连接;倾斜段适于在碰撞时作用于第一连接件且使第一连接件发生断裂,且第一连接件设置为在碰撞时先于第二连接件发生断裂。本发明的前副车架组件,在第一连接件断裂时,下摆臂的内侧前端与第一连接件脱离以朝向外侧甩出,而内侧后端始终保持与车架纵梁连接,以使下摆臂的内侧前端适度的甩出,防止车轮朝向车内侧运动对车内人员造成威胁。
