Description
Technical field
The invention belongs to vehicular clutch technical field, and in particular to a kind of tractor clutch with hydraulic booster manipulates
Mechanism.
Background technology
At present, what the clutch release system of many tractors used is all mechanical manipulation mechanism, with tractor work(
The continuous improvement of rate, also higher is required to the torque-transfer capability of clutch, to increase the coefficient of torque reserve of clutch, generally
Using increasing clutch friction plate diameter and two methods of disk spring thrust are increased, but because structure limits, clutch
The space that friction plate diameter can increase is very limited, therefore often improves clutch using the method for increasing disk spring thrust
Device coefficient of torque reserve, it is heavy that the increase of disk spring thrust result in clutch pedal steering force, adds driver's
Labor intensity, greatly reduce the handling comfort of tractor.
The content of the invention
For problem present in background technology, the invention provides a kind of tractor clutch manipulation with hydraulic booster
Mechanism, the coefficient of torque reserve of clutch can not only be increased, and there is good handling comfort.The machine of former car is not destroyed
Tool clutch, in no hydraulic pressure, mechanical clutch can also be used as usual, and double protection is played to clutch.
The present invention adopts the following technical scheme that：
A kind of tractor clutch operating mechanism with hydraulic booster, including the clutch pedal being arranged in driver's cabin and
Play the booster of power-assisted, it is characterised in that：The front end of the clutch pedal is clutch pedal rocking arm, the clutch
Return spring is connected with pedal rocker arm and connection is pitched；
The booster is arranged on the top of clutch pedal rocking arm, the piston rod on the booster by connect fork with
Clutch separation pull bar connects.
Further, the booster piston bar is connected with being connected one end of fork, the clutch separation pull bar and company
The other end for connecing fork is connected.
Further, oil inlet pipe is connected with the booster and determines throttle orifice；The oil inlet pipe connection tractor turns
It is described to determine throttle orifice by oil hose with turning to constant flow pump to the stable delivery outlet of monostable flow divider on constant flow pump output pipe
Fuel tank connects.
Due to being provided with booster in the top of clutch pedal, power-assisted oil cylinder by tractor steering constant current pump main
Road provides pressure, and the piston rod of booster is connected on clutch separation pull bar by connecting fork, when driver steps on clutch
During pedal, power is provided to the choke valve in power-assisted oil cylinder piston first, booster upper and lower cavity is produced pressure differential, promotes piston
Bar pulls clutch separation pull bar, makes clutch separation.
Relative to prior art, the advantage of the invention is that：
1. the present invention can not only increase the coefficient of torque reserve of clutch, and have good handling comfort.
2. the present invention does not destroy the mechanical clutch of former car, when not having hydraulic pressure, mechanical clutch can also use as usual, to from
Clutch plays double protection.
3. the present invention effectively reduces the labor intensity of driver, the handling comfort of tractor is considerably increased.
Brief description of the drawings
Fig. 1 is the structural representation of apparatus of the present invention.
In figure：1. clutch pedal；2. return spring；3. connection fork；4 boosters；5. oil inlet pipe；6. determine throttle orifice；7.
Booster piston bar；8. choke valve；9. clutch separation pull bar；10. clutch pedal rocking arm
Embodiment
The present invention is further described below in conjunction with the accompanying drawings：
A kind of tractor clutch operating mechanism with hydraulic booster as shown in Figure 1, including be arranged in driver's cabin
Clutch pedal 1 and the booster 4 for playing power-assisted, it is characterised in that：The front end of the clutch pedal 1 is clutch pedal
Rocking arm 10, return spring 2 and connection fork 3 are connected with the clutch pedal rocking arm 10；The booster 4 is arranged on clutch
The top of pedal rocker arm 10, the piston rod 7 on the booster 4 are connected by connecting fork 3 with clutch separation pull bar 9.It is described
The piston rod 7 of booster 4 is connected with being connected one end of fork 3, the clutch separation pull bar 9 and the other end phase for being connected fork 3
Even.Oil inlet pipe 5 is connected with the booster 4 and determines throttle orifice 6；The steering constant flow pump that the oil inlet pipe 5 connects tractor is defeated
Go out the stable delivery outlet of monostable flow divider on pipeline, it is described determine throttle orifice 6 and connected by oil hose with steering constant flow pump fuel tank.
Choke valve 8 is provided with oil inlet pipe 5 simultaneously.The clutch separation pull bar 9 connects the clutch linkage (clutch point
Structure of disembarking is known in the art technology, and here is omitted for its structure).
The operation principle of apparatus of the present invention：
When clutch pedal 1 is not operated, choke valve 8 is in open mode, and the hydraulic oil for turning to constant flow pump output is worn
Booster 4 is crossed to return in steering constant flow pump fuel tank.When driver tramples clutch pedal 1, first close choke valve, it is caused
Pressure differential produces thrust to the piston of power-assisted oil cylinder 4, by controlling the i.e. controllable choke valve of pedal force to clutch pedal 1 to close
The size closed and the Extraction rate for determining throttle orifice 6, and then control cavity pressure；Piston rod 7 is promoted to move, and then by being connected to
Connection fork drive clutch separation pull bar 9 on piston rod 7 realizes the separation of clutch.
When driver's stopping acts, choke valve is in semi-closed state, to keep the pressure in power-assisted oil cylinder 4, makes machine
Structure is in poised state, if applying pressure to clutch pedal 1 again, power-assisted oil cylinder 4 just repeats above-mentioned action, plays power-assisted work
With.When driver's engagement the clutch 1, the return of clutch pedal 1 in the presence of return spring 2, choke valve 8 is opened,
Whole cavity produces certain pressure in the presence of throttle orifice 6 is determined, and forces piston rod to discharge and reset, now clutch starts to tie
Close, and by controlling the openings of sizes lifted speed and can control choke valve 8 of clutch pedal 1, and then control clutch knot
The speed of conjunction.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the involved claim of limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
