Description
Technical field
The present invention relates to manufacture of agricultural machinery technical field, especially a kind of trac..
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.: 1, this bridge case with three road power take-off units is subject to the restriction of its structure, cause the output torque of the output shaft being connected with agricultural machinery and implement little, while causing using agricultural machinery and implement to deep plough operation, can only reach the degree of depth of 200 millimeters; Make agricultural machinery and implement obtain large operation power and increase the just necessary volume that increases bridge case of output torque, thereby affect the sensitivity of trac. operation; In addition, because the output torque of output shaft is little, while running into the obstacle obstructions such as boulder when agricultural machinery and implement, trac. need be stopped, hindering after the obstacle cleanings such as boulder of agricultural machinery and implement, just can proceed operation, production operation efficiency is low; 2, be that the gear in bridge case is carried out to hand shift during trac. speed change, can only between a plurality of gears that set, carry out gear shift.
Summary of the invention
Problem solved by the invention be to provide a kind of can reasonable distribution the trac. of power output, to solve the little and low problem of production operation efficiency of the operation power of existing trac..
In order to address the above problem, the technical solution used in the present invention is: this trac. includes driving engine, the output shaft of described driving engine is connected with the power distribution case between front driving axle and rear driving axle, one output shaft of described power distribution case is connected with the input shaft that is provided with the Hydraulic Pump of guide's hydraulic control handle, described Hydraulic Pump is connected with HM Hydraulic Motor, and described HM Hydraulic Motor connects respectively the input shaft of described front driving axle and described rear driving axle by change speed gear box; Another 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 the agricultural machinery and implement output shaft of described rear transmission gear box is connected with the transmission shaft of agricultural machinery and implement.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect: 1, the driving engine due to this trac. is high-performance driving engine, driving engine is divided into operation power unit and walking power unit by power distribution case, one can reasonable distribution power, improve operation power, make agricultural machinery and implement obtain maximum driving torque, improve operating efficiency, the degree of depth of deep ploughing operation can reach 400 millimeters; It can expand the variation range of the torque and rotational speed of power output by changing transmitting ratio two owing to being provided with power distribution case, makes to start function preferably under operating mode, working; 2, the delivery rate that adopts guide's hydraulic control handle to control Hydraulic Pump carrys out the rotating speed of regulator solution pressure motor, realize the stepless speed variation of each gear in change speed gear box, simplified 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing trac..
Fig. 2 is the structural representation of example of the present invention.
