Abstract
The invention discloses a harvester driving device. The harvester driving device comprises a variable pump connected with an engine of a harvester. The variable pump is connected with a constant displacement motor and a variable displacement motor. The constant displacement motor is in drive connection with a gearbox, the gearbox is in drive connection with a front axle of the harvester, a clutch is arranged on a rear axle of the harvester, and the variable displacement motor is in drive connection with the rear axle of the harvester through the clutch. By means of the walking driving device of the hydraulic four-wheel drive harvester, the problem that when the harvester is in a plant transfer working condition, a variable displacement motor rotates at high speed, and power losses are caused is solved, meanwhile, the influence of high-speed rotation of the variable displacement motor on the reliability of the variable displacement motor is avoided, and the reliability of a hydraulic system is improved.
Description
Technical field
The present invention relates to agricultural machinery technological field, and in particular to one kind harvesting machine actuating device.
Background technology
For current domestic hydraulic pressure 4 wheel driven harvesting machinery, general front-wheel drive is using fixed displacement motor and case bridge, rear wheel driving
It is dynamic to adopt variable displacement motor and case bridge.For this scheme, when harvesting machinery is operated in turns factory's operating mode, need rear wheel drive
Variable displacement motor discharge capacity is adjusted to 0, makes trailing wheel become freewheel state, and variable displacement motor followed by the traveling of vehicle and rotate at a high speed,
The rotating speed of variable displacement motor is about 4000-6000r/min, and in this case at a high speed rotation produces larger power damage to variable displacement motor
Lose, while the reliability of variation motor.
The content of the invention
(1) technical problem to be solved
In order to overcome prior art not enough, it is proposed that one kind harvesting machine actuating device, to solve when harvester is turning factory's work
During condition, variable displacement motor followed by the traveling of vehicle and rotate at a high speed, power loss be caused, while the reliability of variation motor
Technical problem.
(2) technical scheme
The present invention is achieved through the following technical solutions：The present invention proposes a kind of harvesting machine actuating device, including connection institute
The variable pump of the engine of harvester is stated, the variable pump connects respectively fixed displacement motor and variable displacement motor, and the fixed displacement motor is passed
Dynamic connection gearbox, the gearbox transmission connects the propons of the harvester, and the back axle of the harvester is provided with clutch,
The variable displacement motor connects the back axle of the harvester by the driven by clutches.
Used as a kind of improvement, the variable pump is Closed Hydraulic variable pump.
(3) beneficial effect
The present invention has the advantages that relative to prior art：
A kind of harvesting machine actuating device that the present invention is mentioned, because the travel driving unit of hydraulic pressure 4 wheel driven harvester is in harvesting
The back axle of machine is provided with clutch, thus when harvester needs 4 wheel driven, by clutch by after variable displacement motor and harvester
Bridging connects, and fixed displacement motor and variable displacement motor work simultaneously；When 4 wheel driven is not needed, by clutch by variable displacement motor and harvester
Back axle connection disconnect, while variable displacement motor discharge capacity is adjusted to into 0, variable displacement motor will quit work, and rotating speed is 0, variable displacement motor
Not the traveling of following vehicle and rotate at a high speed, variable displacement motor will not produce power loss so that energy saving of system, while avoiding change
Impact of the rotation to variable displacement motor reliability at a high speed of amount motor, now only fixed displacement motor works, at this moment the working condition of vehicle
For front-wheel drive.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
A kind of harvesting machine actuating device as shown in Figure 1, including the variable pump 2 of the engine 1 of connection harvester, preferably
, variable pump 2 is Closed Hydraulic variable pump, and variable pump 2 connects respectively fixed displacement motor 3 and variable displacement motor 4, and fixed displacement motor 3 is driven
Connection gearbox 5, gearbox 5 is connected the propons 6 of harvester, and the back axle 7 of harvester is provided with clutch 8, variable displacement motor 4
Be connected the back axle 7 of harvester by clutch 8.
Wherein, the variable pump 2 is Closed Hydraulic variable pump.
One kind that the present invention is mentioned gathers in machine actuating device, and its operation principle is：When harvester needs 4 wheel driven, pass through
Clutch 8 connects on the back axle 7 of variable displacement motor 4 and harvester, and fixed displacement motor 3 and variable displacement motor 4 work simultaneously；When not needing four
During drive, the connection of the back axle 7 of variable displacement motor 4 and harvester is disconnected by clutch 8, while the discharge capacity of variable displacement motor 4 is adjusted to
0, variable displacement motor 4 will quit work, and rotating speed is 0, variable displacement motor 4 not the traveling of following vehicle and rotate at a high speed, variable displacement motor 4 is not
Power loss can be produced so that energy saving of system, while avoiding shadow of the rotation to the reliability of variable displacement motor 4 at a high speed of variable displacement motor 4
Ring, now only fixed displacement motor 3 works, at this moment the working condition of vehicle is front-wheel drive.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the structure of the present invention
Think and scope is defined.On the premise of without departing from design concept of the present invention, technology of this area ordinary person to the present invention
Various modifications and improvement that scheme is made, all should drop into protection scope of the present invention, the technology contents that the present invention is claimed,
All record in detail in the claims.
