The invention provides an auxiliary frame and a vehicle. The auxiliary frame comprises auxiliary frame longitudinal beams and an auxiliary frame cross beam connected between the auxiliary frame longitudinal beams on the two sides. The auxiliary frame longitudinal beams on the two sides are each provided with a vehicle body installation support, the auxiliary frame cross beam is located between the vehicle body installation supports on the two sides, suspension installation points are arranged on the auxiliary frame cross beam, and a reinforcing structure is arranged on the rear side of the auxiliary frame cross beam. One end of the reinforcing structure is connected to the auxiliary frame cross beam, and the other two ends of the reinforcing structure are connected to the rear ends of the auxiliary frame longitudinal beams on the two sides respectively. According to the auxiliary frame, the auxiliary frame cross beam is located between the vehicle body installation supports on the two sides, the reinforcing structure connected with the auxiliary frame longitudinal beams on the two sides is arranged, the rigidity of the auxiliary frame cross beam is improved conveniently, the reinforcing structure can be matched with the auxiliary frame cross beam to disperse suspension stress, the rigidity of the suspension installation point position of the auxiliary frame can be improved, and the suspension installation effect is improved. And the vibration transmission sensitivity of the auxiliary frame can be reduced, so that the driving comfort of the vehicle can be improved.
本发明提供了一种副车架及车辆,本发明的副车架包括副车架纵梁,以及连接在两侧副车架纵梁之间的副车架横梁;两侧副车架纵梁上均设有车身安装支架,副车架横梁位于两侧车身安装支架之间,且副车架横梁上设有悬置安装点,并在副车架横梁的后侧设有加强结构;加强结构的一端连接在副车架横梁上,加强结构的另两端分别连接在两侧副车架纵梁的后端。本发明的副车架,通过使副车架横梁位于两侧车身安装支架之间,以及设置与两侧副车架纵梁连接的加强结构,便于提升副车架横梁的刚度,且加强结构能够配合副车架横梁分散悬置受力,能够提高副车架悬置安装点位置的刚度,且可降低副车架振动传递灵敏度,而有利于提升车辆驾乘舒适性。
