The invention relates to the technical field of commercial vehicles, and discloses a tractor frame which comprises a left longitudinal beam, a right longitudinal beam, a front sealing plate, a transmission cross beam, a rear suspension front support cross beam and a rear cross beam. The front sealing plate is connected to the front end of the left longitudinal beam and the right longitudinal beam. The transmission cross beam and the rear suspension front support cross beam are both connected to the middle of the left longitudinal beam and the middle of the right longitudinal beam, traction base connecting plates are arranged on the left longitudinal beam and the right longitudinal beam; and first grooves are formed in the bottoms, located on the traction base connecting plates, of the left longitudinal beam and the right longitudinal beam. The rear end of the left longitudinal beam and the rear end of the right longitudinal beam are both provided with notches, and the rear cross beam is connected between the notches in the left longitudinal beam and the notches in the right longitudinal beam. According to the tractor frame provided by the invention, the first grooves are formed to avoid a vehicle rear axle; meanwhile, the notches are formed to avoid the trailer carriage, the saddle height, the gravity center of the whole vehicle and the wind resistance of the whole vehicle are reduced, and the vehicle maneuverability and the driving stability are improved.

    本发明涉及商用车技术领域,公开了一种牵引车车架,包括左纵梁、右纵梁、前封板、变速器横梁、后悬架前支座横梁和后横梁,所述前封板连接在所述左纵梁及所述右纵梁的前端,所述变速器横梁及所述后悬架前支座横梁均连接在所述左纵梁及所述右纵梁的中部,所述左纵梁及所述右纵梁上均设有牵引座连接板,所述左纵梁及所述右纵梁位于所述牵引座连接板的位置的底部设有第一凹槽,所述左纵梁及所述右纵梁的后端均设有缺口,所述后横梁连接在所述左纵梁及所述右纵梁上的所述缺口之间。本发明提供的牵引车车架,通过设置第一凹槽避让车辆后桥;同时设置缺口避让挂车车厢,降低了鞍座高度、整车的重心及整车风阻,提高了车辆操纵性及行驶稳定性。
