Abstract

The invention discloses a tractor, and relates to the technical field of agricultural machine manufacturing. The tractor comprises an engine, and an output shaft of the engine is connected with a power distribution box arranged between a front drive axle and a rear drive axle. A first output shaft of the power distribution box is connected with a first hydraulic pump, the first hydraulic pump is connected with a first hydraulic motor, and the first hydraulic motor is connected with gear transmission cases arranged at the two ends of an input shaft of an agricultural implement. A second output shaft of the power distribution box is connected with a second hydraulic pump, and the second hydraulic pump is communicated with a lifting oil cylinder of an agricultural implement suspension device through a second electromagnetic valve set. A third output shaft of the power distribution box is connected with a third hydraulic pump, the third hydraulic pump is connected with a third hydraulic motor, and the third hydraulic motor is connected with an input shaft of the front drive axle and an input shaft of the rear drive axle through a gearbox. Compared with the prior art, the tractor can solve the problems that an existing tractor is insufficient in traction force and poor in power output performance during tractor-ploughing operation.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery manufacturing, in particular to a tractor for transmitting power through a hydraulic system. Background technique [0002] There is an existing figure 1 The wheeled tractor shown includes an axle box 105 connected to the engine 101 through a coupling 103 and a clutch 102 in sequence, and three power output units are arranged on the axle box 105, and one power output unit is driven by the rear axle. The wheel 104, one power output unit drives the agricultural implement 107 through the output shaft 106, and the one power output unit drives the three-point suspension device 108 connected to the agricultural implement through the lifting box 109. The power transmission device of this tractor has the following problems in the use process: 1. This axle box with three-way power output unit is limited by its structure, causing the output torque of the output shaft connected with the agricu...
