The invention discloses a front auxiliary frame and a vehicle, and the front auxiliary frame comprises two frame longitudinal beams which are distributed at intervals in the transverse direction of the vehicle; the front cross beam and the middle cross beam are both connected between the two frame longitudinal beams, and the front cross beam and the middle cross beam are distributed in the longitudinal direction of the vehicle in a spaced mode; wherein each frame longitudinal beam is arranged to obliquely extend relative to the longitudinal direction of the vehicle from back to front, the two frame longitudinal beams are arranged to be inclined in the direction away from each other from back to front, and the ratio of the extension length of the front cross beam to the extension length of the middle cross beam is 1.4-1.7. According to the front auxiliary frame disclosed by the embodiment of the invention, the two frame longitudinal beams are arranged to obliquely extend relative to the longitudinal direction of the vehicle from back to front, so that impact force during offset collision of the vehicle can be absorbed and dispersed, and the ratio of the extension length of the front cross beam to the extension length of the middle cross beam is 1.4-1.7, so that the working reliability of the frame longitudinal beams can be improved, and the service life of the frame longitudinal beams is prolonged. And the vehicle body structure and the safety of passengers are protected.

    本发明公开了一种前副车架和车辆,前副车架包括:两个车架纵梁,两个车架纵梁沿车辆横向间隔开分布;前部横梁和中部横梁,前部横梁和中部横梁均连接于两个车架纵梁之间,且前部横梁和中部横梁沿车辆纵向间隔开分布;其中,每个车架纵梁均设置为从后往前相对于车辆纵向倾斜延伸,且两个车架纵梁构造为从后往前朝远离彼此的方向倾斜,前部横梁的延伸长度与中部横梁的延伸长度的比例为1.4~1.7。本发明实施例的前副车架,将两个车架纵梁均设置为从后往前相对于车辆纵向倾斜延伸,可对车辆偏置碰撞时的冲击力进行吸收与分散,且使前部横梁的延伸长度与中部横梁的延伸长度的比例为1.4~1.7,可提升车架纵梁工作的可靠性,对车身结构和乘客安全进行保护。
