Existing a kind of wheeled trac. as shown in Figure 1, this trac. comprises successively by bridge case 105 that coupler 103 is connected with driving engine 101 with power-transfer clutch 102, bridge case 105 is 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 by output shaft 106, and a road power take-off unit drives the three-point attachment 108 connecting agricultural machinery and implement by lift tank 109.In use there are the following problems for the power drive of this trac.: this restriction of bridge case by its structure with three road power take-off units, causes the output torque of the output shaft be connected with agricultural machinery and implement little, Power output poor performance during tractor-ploughing operation; In addition, because the output torque of output shaft is little, when running into the obstacle obstructions such as boulder when agricultural machinery and implement, trac. need be stopped, 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 the trac. of reasonable distribution Power output, Power output poor performance and production operation efficiency low problem during to solve existing trac. tractor-ploughing operation.
In order to solve the problem, the technical solution adopted in the utility model is: this trac. includes driving engine, the output shaft of described driving engine is connected with the power distribution case be located between front driving axle and rear driving axle, first output shaft of described power distribution case is connected with the first Hydraulic Pump, the delivery port of described first Hydraulic Pump is communicated with the oil inlet of the first HM Hydraulic Motor with the first electromagnetic valve group by oil pipe, and described first HM Hydraulic Motor is connected with the gear being contained in agricultural machinery and implement input shaft two ends; Second output shaft of described power distribution case is connected with the second Hydraulic Pump, and the delivery port of described second Hydraulic Pump is communicated with the oil inlet of the elevating ram of agricultural implement hanging device with the second electromagnetic valve group by oil pipe; 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: described first electromagnetic valve group is connected with the second master cock with the first master cock respectively with the valve control end of described second electromagnetic valve group.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect 1, is divided into machine work power unit and mechanical drive driver element by part-time case due to driving engine, one can reasonable distribution power, improve operation power, make agricultural machinery and implement obtain maximum driving torque, improve operating efficiency; It is two owing to being provided with part-time case, by changing transmitting ratio, expands the variation range of the torque and rotational speed of Power output, makes to start function to work under preferably operating mode; 2, because master cock Controlling solenoid valve group changes hydraulic flow, pressure reduction, expand the variation range of the torque and rotational speed of Power output, to adapt to the physical features of often change, make driving engine work under preferably operating mode simultaneously; Controlling solenoid valve group can interrupt transmission of power, and agricultural machinery and implement are quit work, and car load can be made like this not to be affected in road driving, temporary shut down and field adjustment, and production operation efficiency is improved; The hydraulic flow of the master cock hydraulic control pump 3, be connected with electromagnetic valve group realizes controlling the rotation of agricultural machinery and implement, the stopping of agricultural machinery and implement and gearshift can be completed in good time, simplify the control action of chaufeur, further mitigate the strength at repeated alternation of chaufeur, and there is torque reserve ability, while non-slip guaranteeing to transmit driving engine output maximum torque, can prevent again transmission system from transshipping, thus avoid the damage of part in a series of driving system, the Power output performance of trac. is obtained and greatly strengthens; 4, the power of driving engine is passed through the second output shaft by transmission of power to dynamic power shift gear box by part-time case by mechanical drive driver element,, rear propeller shaft premenstrual by dynamic power shift gear box drives the front and rear wheel walking of trac. again, the all dynamic driving of front and rear wheel, makes the dynamic property of trac. car load, safety, road-holding property, crossing ability good.
