Summary of the invention
Problem solved by the invention 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 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 being located between front driving axle and rear driving axle, the first output shaft of described power distribution case is connected with the first Hydraulic Pump, the delivery port of described the first Hydraulic Pump is communicated with the oil inlet of the first HM Hydraulic Motor by oil pipe and the first electromagnetic valve group, and described the first HM Hydraulic Motor is connected with the gear that is contained in agricultural machinery and implement input shaft two ends; The second output shaft of described power distribution case is connected with the second Hydraulic Pump, and the delivery port of described the second Hydraulic Pump is communicated with the oil inlet of the elevating ram of agricultural implement hanging device by oil pipe and the second electromagnetic valve group; The 3rd output shaft of described power distribution case is connected with the input shaft of described front driving axle and described rear driving axle respectively by change speed gear box.
In above-mentioned trac. technical scheme, technical scheme can also be more specifically: the valve control end of described the first electromagnetic valve group and described the second electromagnetic valve group is connected with the second master cock with the first master cock respectively.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect 1, because driving engine is divided into machine work power unit and mechanical drive driver element by part-time 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 part-time case, makes to start function preferably under operating mode, working; 2, because master cock control electromagnetic valve group changes hydraulic flow, pressure reduction, expand the variation range of the torque and rotational speed of power output, with the physical features that adapts to often change, make driving engine preferably under operating mode, work simultaneously; Control electromagnetic valve group and can interrupt transmission of power, agricultural machinery and implement are quit work, can make like this car load not be affected in road driving, temporarily parking and field adjustment, production operation efficiency is improved; The hydraulic flow of the master cock control Hydraulic Pump 3, being connected with electromagnetic valve group is realized the rotation of controlling agricultural machinery and implement, make agricultural machinery and implement stop and shifting gears can complete in good time, simplify the control action of chaufeur, further alleviate the strength at repeated alternation 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, make the power output performance of trac. obtain enhancing greatly; 4, mechanical drive driver element by the power of driving engine by part-time case by the second output shaft by transmission of power to dynamic power shift gear box,, rear propeller shaft premenstrual by dynamic power shift gear box drives the front and rear wheel walking of trac. again, front and rear wheel is dynamic driving all, makes dynamic property, safety, road-holding property, the crossing ability of trac. car load good.
