The invention discloses a front auxiliary frame and a vehicle, and belongs to the technical field of vehicles, two first connecting parts are arranged on the left side and the right side of a front cross beam respectively, two second connecting parts are arranged on the left side and the right side of a rear cross beam respectively, and a third connecting part is arranged at the rear end of a longitudinal beam; the first connecting part, the second connecting part and the third connecting part can enlarge the front-back span of connection between the front auxiliary frame and a vehicle body, the overall stress of the front auxiliary frame is effectively dispersed, the first reinforcing rib is beneficial to improving the connecting rigidity of the first connecting part and the nearby position, and the second reinforcing rib is beneficial to improving the connecting rigidity of the second connecting part and the nearby position. The third reinforcing rib improves the connecting rigidity of the third connecting part and the position nearby the third connecting part, improves the rigidity of the front auxiliary frame bearing the vehicle body, and attenuates bad vibration generated by a power assembly of the vehicle and transmitted to the vehicle body, so that the modality and the strength are improved.
本发明公开了一种前副车架及车辆,属于车辆技术领域,其中两个第一连接部分别设置在前横梁的左侧和右侧,两个第二连接部分别设置在后横梁的左侧和右侧,第三连接部设置在纵梁的后端,第一连接部、第二连接部和第三连接部能够加大前副车架和车身连接的前后跨距,有效地分散了前副车架的整体受力,第一加强筋有助于提高第一连接部及其附近位置的连接刚度,第二加强筋提高第二连接部及其附近位置的连接刚度,第三加强筋提高第三连接部及其附近位置的连接刚度,提升前副车架承载车身的刚度,衰减由车辆的动力总成产生并向车身传递的不良振动,从而提高模态和强度。
