The invention discloses an auxiliary frame which comprises a front cross beam, front section longitudinal beams connected with the front cross beam, rear section longitudinal beams connected with the front section longitudinal beams, an auxiliary frame upper plate and an auxiliary frame lower plate, the auxiliary frame upper plate and the auxiliary frame lower plate are connected with the rear section longitudinal beams and located between the two rear section longitudinal beams, and the auxiliary frame upper plate and the auxiliary frame lower plate are connected. The rear-section longitudinal beam is of a box-shaped splicing structure. According to the auxiliary frame, the bending resistance and the torsion resistance can be effectively improved, the overall and local rigidity and strength are improved, cost control is facilitated, and the situation that the auxiliary frame cracks in the vehicle running process due to the fact that rigidity is discontinuous and strength is insufficient due to suspension mounting holes is avoided. The invention further discloses a vehicle.

    本发明公开了一种副车架,包括前横梁、与前横梁连接的前段纵梁、与前段纵梁连接的后段纵梁以及与后段纵梁连接的副车架上板和副车架下板,副车架上板和副车架下板位于两个后段纵梁之间且副车架上板和副车架下板相连接,后段纵梁为盒状拼接结构。本发明的副车架,可以有效提高抗弯、抗扭性能,提升整体及局部刚强度,并利于成本的控制,避免因为悬置安装开孔导致刚度不连续、强度不足,导致车辆行驶过程中副车架开裂。本发明还发明了一种车辆。
