Description
Technical field
The utility model relates to manufacture of agricultural machinery technical field, especially a kind of for the trac. by mechanical system transferring power.
Background technology
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.: 1, this restriction of bridge case by its structure with three road power take-off units, cause 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; 2, owing to driving the power take-off unit of trac. walking to be also that logical bridge case exports, make tractor drawbar pull not enough, particularly when turning, due to the reach of deceleration center of gravity, trailing wheel earth-grasping force reduces, and is easy to cause ovdersteering, occurs whipping phenomenon.
Utility model content
The problem that the utility model solves be to provide a kind of can the trac. of reasonable distribution Power output, the problem of Power output poor performance during to solve the not enough and tractor-ploughing operation of existing tractor drawbar pull.
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, one output shaft of described power distribution case is connected with the rear transmission gear box being located at described rear driving axle rear by the first transmission shaft, and described rear transmission gear box is connected with driving the second driving shaft of agricultural machinery and implement by its agricultural machinery and implement output shaft; Described power distribution case is connected with change speed gear box by another output shaft, and described change speed gear box is connected with the described rear driving axle being provided with trailing wheel with the described front driving axle being provided with front-wheel with rear propeller shaft respectively by front propeller shaft.
In above-mentioned trac. technical scheme, technical scheme can also be more specifically: described first transmission shaft between described power distribution case and described rear transmission gear box input shaft, described second driving shaft between described agricultural machinery and implement output shaft and described agricultural machinery and implement input shaft, described front propeller shaft between described front driving axle input shaft and described dynamic power shift gear box front output shaft and described rear propeller shaft between described dynamic power shift gear box rear output shaft and described rear driving axle input shaft, be equipped with universal-joint.
Owing to have employed 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 mechanical 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 is two owing to being provided with power distribution 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, machine work power unit is by engine power, rear transmission gear box is passed to by the first transmission shaft through power distribution case, power is directly passed to agricultural machinery and implement by agricultural machinery and implement output shaft by second driving shaft by rear transmission gear box, improves the reliability that engine power exports; 3, the power of driving engine is passed through the second output shaft by transmission of power to dynamic power shift gear box by power distribution 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.
