Abstract

The invention discloses a four-wheel drive tractor active torque force distribution system. The system comprises a front drive axle and a rear drive axle, the front drive axle comprises a front differential mechanism shell, a front differential mechanism is arranged in the front differential mechanism shell, the two ends of the front differential mechanism are respectively rotationally connected with a left front drive shaft and a right front drive shaft, the rear drive axle comprises a rear differential mechanism shell, a rear differential mechanism is arranged in the rear differential mechanism shell, the two ends of the rear differential mechanism are respectively rotationally connected with a left rear drive shaft and a right rear drive shaft, front wheels and rear wheels are respectively connected with wheel speed measurement devices, the wheel speed measurement devices are connected with a control system, a clutch device is arranged between the front differential mechanism shelland the left front drive shaft or the right front drive shaft, the control system is connected with a control clutch device; when tires of the tractor skid, the control system actively controls outputpower of an engine and driving force of the front and rear shafts, so that the torque of the engine can always be at a relatively reasonable torque point, and the energy-saving and efficient drivingof a waist wheel-twisting type tractor is achieved.

Description

technical field [0001] The invention relates to a torque distribution system, in particular to an active torque distribution system for a tractor that actively adjusts the output power of the engine and the driving force of the front and rear axles to maintain the stability and passability of the engine. Background technique [0002] There are many hills and mountains in our country, and the hills and mountains have a special working environment with small and uneven work plots. The tractor may slip during driving, and the stability and passability of the engine are poor, which makes it difficult to meet the use requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an active torque distribution system for a four-wheel drive tractor that actively adjusts the output power of the engine and the driving force of the front and rear axles to maintain the stability and passability of the engine. [0004] In ord...
