Description

Trac.

Technical field

The utility model relates to manufacture of agricultural machinery technical field, especially a kind of trac. with hydraulic efficiency pressure system and mechanical system transferring power.

Background technology

Existing a kind of wheeled trac. as shown in Figure 1, this trac. comprises the bridge case 105 being connected with driving engine 101 with power-transfer clutch 102 by coupler 103 successively, on bridge case 105, be provided with three road power take-off units, one road power take-off unit is by rear-axle drive trailing wheel 104, one road power take-off unit drives agricultural machinery and implement 107, one road power take-off units to drive by lift tank 109 three-point attachment 108 that connects agricultural machinery and implement by output shaft 106.In use there are the following problems for the power drive of this trac.: this bridge case with three road power take-off units is subject to the restriction of its structure, causes the output torque of the output shaft being connected with agricultural machinery and implement little, and when tractor-ploughing operation, power output performance is poor; In addition, because the output torque of output shaft is little, while running into the obstacle obstructions such as boulder, trac. need be stopped when agricultural machinery and implement, after the obstacle cleanings such as the boulder of obstruction agricultural machinery and implement, just can proceed operation, production operation efficiency is low.

Utility model content

The problem that the utility model solves be to provide a kind of can reasonable distribution the trac. of power output, the poor and low problem of production operation efficiency of power output performance when solving existing trac. tractor-ploughing operation.

In order to address the above problem, the technical solution adopted in the utility model is: this trac. includes driving engine, described engine output shaft is connected with the power distribution case that is located at rear driving axle front, one output shaft of described power distribution case is connected with the rear transmission gear box that is located at described rear driving axle rear by transmission shaft, and described rear transmission gear box is connected with the axle drive shaft of agricultural machinery and implement by its agricultural machinery and implement output shaft; Another output shaft of described power distribution case is connected with the input shaft of the Hydraulic Pump that is provided with guide's hydraulic control handle, and described Hydraulic Pump is connected with HM Hydraulic Motor, and described HM Hydraulic Motor is connected with the input shaft of described rear driving axle by change speed gear box.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: 1, because driving engine is divided into machine work power unit and hydrostatic drive driver element by power distribution case, one can reasonable distribution power, improve operation power, make agricultural machinery and implement obtain maximum driving torque, improve operating efficiency; It can, by changing transmitting ratio, expand the variation range of the torque and rotational speed of power output two owing to being provided with power distribution case, makes to start function preferably under operating mode, working; 2, adopt the delivery rate of guide's hydraulic control handle control Hydraulic Pump to carry out the rotating speed of regulator solution pressure motor, realize the stepless speed variation of each gear in change speed gear box, simplify the control action of chaufeur, the light fatigue of chaufeur, and there is torque reserve ability, guaranteeing to transmit driving engine output maximum torque in non-slip, can prevent again transmission system overload, thereby avoid the damage of part in a series of driving systems, the power output performance of subsoiling machine of working soil and the ability of leaping over obstacles are strengthened greatly, improve production operation efficiency; 3, hydrostatic drive driver element passes to rear transmission gear box through power distribution case by transmission shaft by engine power, and rear transmission gear box is directly passed to agricultural machinery and implement by second driving shaft by power by agricultural machinery and implement output shaft, improves the reliability of engine power output.

Brief description of the drawings
