Abstract
The utility model discloses a travel driving unit of hydraulic pressure 4 wheel driven harvester belongs to agricultural machine technical field, including connecting the variable pump of the engine of harvester, constant displacement motor and variable displacement motor are connected respectively to the variable pump, the gearbox is connected in the constant displacement motor transmission, gearbox transmission connects the front axle of harvester, be equipped with the clutch on the rear axle of harvester, the variable displacement motor passes through the clutch transmission is connected the rear axle of harvester. The utility model provides a travel driving unit of hydraulic pressure 4 wheel driven harvester solved when the harvester when changeing factory's operating mode, the high -speed rotatory influence to the variable displacement motor reliability of variable displacement motor has been avoided simultaneously to the high -speed rotatory power loss that causes of variable displacement motor, has promoted hydraulic system's reliability.
Description
Technical field
This utility model belongs to agricultural machinery technological field, particularly relates to the travel driving unit of a kind of hydraulic pressure 4 wheel driven harvester.
Background technology
For hydraulic pressure 4 wheel driven harvesting machinery domestic at present, general front-wheel drive adopts fixed displacement motor and case bridge, and rear wheel drive adopts variable displacement motor and case bridge. For this scheme, when harvesting machinery is operated in and turns factory's operating mode, need the variable displacement motor discharge capacity of rear wheel drive is adjusted to 0, trailing wheel is made to become freewheel state, variable displacement motor followed by the traveling of vehicle and high speed rotating, the rotating speed of variable displacement motor is about 4000 6000r/min, and variable displacement motor high speed rotating produces bigger power loss in this case, simultaneously the reliability of variation motor.
Utility model content
Technical problem to be solved in the utility model is: provide the travel driving unit of a kind of hydraulic pressure 4 wheel driven harvester, to solve when harvester is when turning factory's operating mode, variable displacement motor followed by the traveling of vehicle and high speed rotating, cause power loss, simultaneously the technical problem of the reliability of variation motor.
For solving above-mentioned technical problem, the technical solution of the utility model is: the travel driving unit of hydraulic pressure 4 wheel driven harvester, variable pump including the electromotor connecting described harvester, described variable pump connects fixed displacement motor and variable displacement motor respectively, described fixed displacement motor is in transmission connection change speed gear box, described gearbox transmission connects the propons of described harvester, and the back axle of described harvester is provided with clutch, and described variable displacement motor connects the back axle of described harvester by described driven by clutches.
Improving as one, described variable pump is Closed Hydraulic variable pump.
After have employed technique scheme, the beneficial effects of the utility model are: owing to the travel driving unit of hydraulic pressure 4 wheel driven harvester is provided with clutch on the back axle of harvester, thus when harvester needs 4 wheel driven, being connected by the back axle of variable displacement motor and harvester by clutch, fixed displacement motor and variable displacement motor work simultaneously; When not needing 4 wheel driven, by clutch, the connection of variable displacement motor and the back axle of harvester is disconnected, variable displacement motor discharge capacity being adjusted to 0, variable displacement motor will quit work simultaneously, and rotating speed is 0, variable displacement motor does not follow the traveling of vehicle and high speed rotating, variable displacement motor will not produce power loss so that energy saving of system, avoids the impact on variable displacement motor reliability of the variable displacement motor high speed rotating simultaneously, now only having fixed displacement motor work, at this moment the duty of vehicle is front-wheel drive.
The travel driving unit of the hydraulic pressure 4 wheel driven harvester that this utility model provides solves when harvester is when turning factory's operating mode, the power loss that variable displacement motor high speed rotating causes, avoid the impact on variable displacement motor reliability of the variable displacement motor high speed rotating simultaneously, improve the reliability of hydraulic system.

In figure: 1, electromotor, 2, variable pump, 3, fixed displacement motor, 4, variable displacement motor, 5, change speed gear box, 6, propons, 7, back axle, 8, clutch.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As shown in Figure 1, a kind of travel driving unit of hydraulic pressure 4 wheel driven harvester, variable pump 2 including the electromotor 1 connecting harvester, preferably, variable pump 2 is Closed Hydraulic variable pump, and variable pump 2 connects fixed displacement motor 3 and variable displacement motor 4 respectively, fixed displacement motor 3 is in transmission connection change speed gear box 5, change speed gear box 5 is in transmission connection the propons 6 of harvester, and the back axle 7 of harvester is provided with clutch 8, and variable displacement motor 4 is in transmission connection by clutch 8 back axle 7 of harvester.
Its operation principle is as follows:
When harvester needs 4 wheel driven, being connected by the back axle 7 of variable displacement motor 4 and harvester by clutch 8, fixed displacement motor 3 and variable displacement motor 4 work simultaneously; When not needing 4 wheel driven, by clutch 8, the connection of the back axle 7 of variable displacement motor 4 and harvester is disconnected, variable displacement motor 4 discharge capacity being adjusted to 0, variable displacement motor 4 will quit work simultaneously, and rotating speed is 0, variable displacement motor 4 does not follow the traveling of vehicle and high speed rotating, variable displacement motor 4 will not produce power loss so that energy saving of system, avoids the impact on variable displacement motor 4 reliability of variable displacement motor 4 high speed rotating simultaneously, now only having fixed displacement motor 3 to work, at this moment the duty of vehicle is front-wheel drive.
The travel driving unit of the hydraulic pressure 4 wheel driven harvester that this utility model provides solves when harvester is when turning factory's operating mode, the power loss that variable displacement motor high speed rotating causes, avoid the impact on variable displacement motor reliability of the variable displacement motor high speed rotating simultaneously, improve the reliability of hydraulic system.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
