Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further illustrated, but protection scope of the present invention is simultaneously
Not limited to this.
A kind of hydraulic-driven cterpillar drive operating mechanism of the present invention, the running gear is by power resources
Driven respectively in the manual duplex variable pump of the discharge capacity such as one of engine or using the independently installed manual variable pump of the discharge capacities such as two
Two hydraulic motors are moved, as the power source of left and right side drive sprocket.
As depicted in figs. 1 and 2, two hydraulic pressure horses are driven using the manual duplex variable pump of the discharge capacity such as one in the present embodiment
Reach, as the power source of left and right side drive sprocket.
The operating mechanism is included before Y shape loop bar 1, connector 2, control stick 4, connecting rod 5, the first preposition pull bar 6, second

8 other end is hinged with first flow regulating valve handle 9, one end the second butterfly driving member 14 of the second rearmounted pull bar 13 it is another
One end is hinged, and the other end and the second flow regulating valve handle 12 of the second rearmounted pull bar 13 are hinged.
As shown in figure 4, in the present embodiment two can also be driven using the independently installed manual variable pump of the discharge capacities such as two
Hydraulic motor, as the power source of left and right side drive sprocket.
As shown in figures 1 and 3, when holding Y shape loop bar 1, front and rear push-and-pull, in the presence of connecting rod 5, the first rearmounted pull bar
8 and the second rearmounted pull bar 13 equidistant movement in the same direction, drive first flow regulating valve handle 9, second flow regulating valve handle
12 forward and reverse synchronous adjustments so that output hydraulic pressure is oily forward or backwards for two variable pumps, makes left hydraulic motor and right side hydraulic pressure
Motor synchronous acceleration or deceleration, forward or reverse, realize linear accelerating or deceleration, the advance or retrogressing of running gear；
Reversed when holding Y shape loop bar 1, it is previous that the first rearmounted pull bar 13 of rearmounted pull bar 8 and second can produce one simultaneously
After move towards, first flow regulating valve handle 9, the positive and negative opposite revolution of second flow regulating valve handle 12 are driven respectively so that
The oily flow increase of one variable pump output hydraulic pressure, the oily flow of another variable pump output hydraulic pressure diminish, and then make left side hydraulic pressure horse
Speed difference is produced up to right hydraulic motor, running gear differential steering is realized.
For the present invention preferred embodiment, but the present invention is not limited to above-mentioned embodiment to the embodiment, not
In the case of the substantive content of the present invention, any conspicuously improved, replacement that those skilled in the art can make
Or modification belongs to protection scope of the present invention.
