The invention relates to a tractor chassis structure for a large single tire and a tractor, the tractor chassis structure for the large single tire comprises a frame assembly, a front axle assembly, a middle axle assembly, a rear axle assembly, two front wheels and four single-tire wheels, the front axle assembly, the middle axle assembly and the rear axle assembly are mounted on the lower side of the frame assembly at intervals from front to back; the two front wheels are installed at the two ends of the front axle assembly respectively, the four single-tire wheels are installed at the two ends of the middle axle assembly and the two ends of the rear axle assembly respectively, the wheel track of the middle axle is consistent with the wheel track of the rear axle, the wheel track of the front axle is close to the wheel track of the rear axle, and the wheel track of the rear axle is L2. A double-tire structure of the middle axle and the rear axle is changed into a large single-tire structure, the weight of a vehicle is reduced, oil consumption is reduced, the widened middle axle assembly and the widened rear axle assembly special for the large single tire are arranged according to the wheel track of the front axle and the outer width of the front axle tires, meanwhile, the corresponding single-tire wheels are matched, the wheel track of the front axle is close to the wheel track of the rear axle, and the wheel track of the rear axle is close to the wheel track of the rear axle. And the control stability performance of the vehicle is improved.
本发明涉及一种大单胎用牵引车底盘结构及牵引车,大单胎用牵引车底盘结构包括车架总成、前桥总成、中桥总成、后桥总成、两个前轮和四个单胎车轮,前桥总成、中桥总成、后桥总成自前之后间隔安装于车架总成的下侧,两个前轮分别安装于前桥总成的两端,四个单胎车轮分别安装于中桥总成和后桥总成的两端,中桥轮距和后桥轮距保持一致,前桥轮距和后桥轮距相近,后桥轮距为L2。本发明将中桥和后桥的双胎结构改为大单胎结构,减轻了车辆自身的重量,降低了油耗,并且根据前桥轮距及前桥轮胎外宽,设置加宽的大单胎专用的中桥总成、后桥总成,同时匹配对应的单胎车轮,使得前桥轮距和后桥轮距相近,改善了车辆操控稳定性能。
