Description
Technical field
The present invention relates to a kind of transmission system, more particularly to a kind of transmission system for crawler belt line harvester.
Background technology
Crawler belt is larger compared with the area that is contacted for wheel with ground, unit area stress is small so that vehicle is difficult to sink, because
This will not destroy plough sole, with good paddy field walking performance, therefore be widely used in farm machinery, such as harvester,
Cultivator etc..Hydraulicdriven crawler-type harvester, its driving control system includes hydraulic pump.Hydraulic pump leans on engine driving,
Fluid is sucked from hydraulic fluid tank, the motor that pressure oil is discharged and delivers to two Athey wheel walkings of control is formed, so as to realize harvesting
The travelling control of machine.Existing hydraulic drive crawler-type harvester, is turned by controlling two motors with identical rotating speed and direction
It is dynamic, it is possible to achieve the front and rear walking of harvester；Rotated by controlling two motors with different rotating speeds or different directions, can
Walked with the steering for realizing harvester.By the operation to hydraulic pump control plate, it can be controlled to export to the oil pressure of motor, from
And the rotating speed and steering of motor are controlled.The rotational angle of hydraulic pump control plate and direction can be controlled to motor：
The rotation direction of hydraulic pump control plate accordingly controls the rotation direction of motor, and the size of the rotational angle of hydraulic pump accordingly controls horse
The rotating speed reached.
The hydraulic drive crawler-type harvester of prior art has following two kinds of control modes：
The first is single pole walking, double-rod steering control modes：Using the hydraulic pressure of an action bars simultaneously to two motors of control
Pump control panel is operable to control the advance or retrogressing of harvester；In addition using two action bars respectively to two horses of control
The hydraulic pump control plate reached is operable to control the steering of harvester.

Driver's handover operation between three action bars is needed under the first control mode, for only having driving for two hands
Handling for the person of sailing is clearly very poor.
Constant speed it can only be turned in situ under second of control mode：Two Athey wheels are respectively with same speed, phase reversal
Move to realize steering, and steering terminates the travel speed that later Athey wheel can not be returned automatically to before turning to, turning speed mistake
It hurry up, than relatively hazardous, and driving experience.

To disk action bars drive and along the length direction of tooth bar towards another side shifting move when, second in slide control 7422 slides
Seat control piece 74221b is contacted with the second slide control 7411b, while keeping first slide control piece 74221a and first to slide
Dynamic control piece 7411a separation so that second slide 741a is moved with slide control 7422, while first slide 741a is kept
It is static.
In the present embodiment, transmission system as shown in figure 1, the now such as Fig. 2 of the state in transmission case institutes when harvester is static
Show.First slide 741a and second slide 741b are located at the two ends of speed change rotating shaft 731, the first chute 751a and the second chute respectively
751b is parallel to speed change rotating shaft 731.First transmission control rotating shaft 711a extended line passes through the first chute 751a center, second
Transmission control rotating shaft 711b extended line passes through the second chute 751b center.
Speed change push rod 5 is connected by the first control input mouthful with speed change rotating shaft transmission, drives speed change to turn by speed change push rod
Axle is rotated, as the connecting rod on the first connecting seat and the second connecting seat of speed change rotating shaft synchronous axial system promotes the first chute simultaneously
With the second chute so that the first chute and the second chute rotate identical angle in a reverse direction with its respective center.Make
Harvester starts the latter forward or walked backward, now transmission system as shown in Figure 3,4, shape body such as Fig. 5 in transmission case,
Shown in 6.
When needing to turn in harvester walking process, slide control is driven to move by steering wheel operation bar 6, and band
One of slide is moved close to another slide, meanwhile, the connecting seat being connected with mobile slide is also by with the movement of slide
Along its speed change rotating shaft synchronizing moving.Driver does not operate to speed change push rod 5 during turning, and connecting seat is along speed change
Rotating shaft is able to maintain that the angle of inclination of the first chute and the second chute is constant during moving.Therefore as shown in figure 8, walking
The first chute and the length direction of the second chute and the moving direction of slide in journey are not parallel, remain angle a.With
It is close between first chute 751a and the second chute 751b, with the first chute 751a close to the second chute 751b in the present embodiment
Exemplified by be described, the first transmission control rotating shaft 711a and the first chute 751（The center of first chute）The distance between will
Change.In the first chute 751a moving process, the first sliding block 721a in the first chute 751a will be along first
Chute moves the new position for being adapted to the first chute.And the first transmission is connected to by the first transmission control panel 712a and controlled
Axle 711a the first sliding block 721a motion track is limited in using the first transmission control shaft 711a as the radii fixus in the center of circle
On circumference, therefore cause the first sliding block 721a using the first transmission control panel 712a as axis rotation, so as to change the first pump control
The angle of making sheet（Such as Fig. 7）So that the rotating speed of motor one generates change.And in whole process due to the second chute position and
Angle does not all change, and the second pump control panel still remains original angle so that motor two keeps original rotation shape
State.So cause there is speed discrepancy between motor one and motor two, realize and turn.
In the present embodiment, set between the excircle of speed change rotating shaft 731, the first connecting seat 7321a and the second connecting seat 7321b
There is return spring 761.After turning terminates, the driving force applied by steering wheel operation bar disappears, in the work of return spring
Under, originally the first slide close to second slide will turn again to the end of speed change rotating shaft away from second slide.This mistake
Cheng Zhong, because the presence of the first connecting seat causes a angles remained between moving direction of the first chute.So that first
The angle that the angle of pump control panel is returned to before turning.Therefore so that harvester is after turning terminates according to the row before turning
Speed is sailed to continue to travel.
Above embodiment is only that this preferred embodiment is described, and not this spirit and scope are limited
It is fixed.On the premise of the design design is not departed from, various modifications and change that this area ordinary person makes to this technical scheme
Enter, this protection domain all should be dropped into, this claimed technology contents has all been recorded in detail in the claims.
