Description
Technical field
This utility model relates to a kind of crawler tractor parts, is specifically related to a kind of crawler tractor and turns to operating mechanism.
Background technology
Turning to of track-type exercise machine is generally all realize by cutting off the driving force of certain side crawler belt.What conventional tracks tractor was commonly used is that manpower pulls stick, reached by machine driving to cut off transmission case side driving-chain and realize: pull certain side stick → by pull bar transmission → pull transmission case top turn to swing arm to rotate → drive to turn to shift fork to swing → stir tooth sector to slide the state that is disengaged from → this side driving-chain disconnection transmission case within, crawler belt shuts down → opposite side crawler belt still in operating, machine turns to this side.As it was previously stated, original structure is to adopt manpower to pull manipulation, by the strength of machinery zip to turning to swing arm to be operated, operate effort, bradykinesia.
Utility model content
What the purpose of this utility model was in that to provide the crawler tractor of a kind of convenient and flexible operation turns to operating mechanism.
nullFor achieving the above object，This utility model provides following technical scheme: a kind of crawler tractor turns to operating mechanism，Including switching valve assembly、The left oil inlet pipe of steering cylinder、The right oil inlet pipe of steering cylinder、Steering cylinder oil return pipe、Steering cylinder assembly、Port swing arm、Turn to right swing arm，Described switching valve assembly is arranged in the frame that tractor driving is indoor，It passes through the left oil inlet pipe of steering cylinder、The right oil inlet pipe of steering cylinder and steering cylinder oil return pipe respectively with the left oil inleting port of the steering cylinder assembly being arranged on transmission case、Right oil-in is connected with oil return opening，With left oil inleting port on described steering cylinder assembly、The other end that right oil-in is corresponding arranges and is each provided with a push rod，Described port swing arm、Turn to right swing arm to be arranged on transmission case and be connected with the shift fork that turns in transmission case，Described turn to right swing arm bottom to be fixedly installed two to turn to projection，Said two turns to bump position corresponding with two push rods respectively.
As further technical scheme of the present utility model, also including steering arm, described steering arm is installed on switching valve assembly.
As further technical scheme of the present utility model, it is provided with return spring in described switching valve assembly and is connected with steering arm.
This utility model is owing to being utilize electromotor steering cylinder directly to drive for power to turn to swing arm to realize go to action, and steering arm is only merely the valve core movement handling switching valve, therefore very light；Control action is directly perceived, it is to avoid maloperation；Hydraulic-driven, is swift in response, sensitive；Conveniently realize pivot stud；All adopt return spring, manipulation does not all need reverse return to operate, unclamp and get final product return voluntarily, very easy.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 turns to hydraulic cylinder assembly and turns to swing arm part structure for amplifying schematic diagram in Fig. 1.
In figure: switching valve assembly 1, steering arm 2, the left oil inlet pipe of steering cylinder 3, the right oil inlet pipe 4 of steering cylinder, steering cylinder oil return pipe 5, steering cylinder assembly 6, port swing arm 7, turn to right swing arm 8.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1-2，This utility model provides a kind of technical scheme: a kind of crawler tractor turns to operating mechanism，Including switching valve assembly 1、The left oil inlet pipe 3 of steering cylinder、The right oil inlet pipe 4 of steering cylinder、Steering cylinder oil return pipe 5、Steering cylinder assembly 6、Port swing arm 7、Turn to right swing arm 8，Described switching valve assembly 1 is arranged in the frame that tractor driving is indoor，It passes through the left oil inlet pipe 3 of steering cylinder、The right oil inlet pipe 4 of steering cylinder and steering cylinder oil return pipe 5 respectively with the left oil inleting port of the steering cylinder assembly 6 being arranged on transmission case、Right oil-in is connected with oil return opening，With left oil inleting port on described steering cylinder assembly 6、The other end that right oil-in is corresponding arranges and is each provided with a push rod，Described port swing arm 7、Turn to right swing arm 8 to be arranged on transmission case and be connected with the shift fork that turns in transmission case，Described turn to right swing arm 8 bottom to be fixedly installed two to turn to projection，Said two turns to bump position corresponding with two push rods respectively.
Also including steering arm 2, described steering arm 2 is installed on switching valve assembly 1.
It is provided with return spring in described switching valve assembly 1 to be connected with steering arm 2.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, being appreciated that when without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, amendment, replacement and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
