Description
Technical field
The invention belongs to vehicular clutch technical field, the tractor clutch being specifically related to a kind of band hydraulic booster is handled
Mechanism.
Background technology
At present, the clutch release system of a lot of tractors uses Dou Shi mechanical manipulation mechanism, along with tractor merit
Improving constantly of rate, requires the highest to the torque-transfer capability of clutch, the coefficient of torque reserve of clutch to be strengthened, generally
Use and strengthen clutch friction plate diameter and strengthen two kinds of methods of disk spring thrust, but owing to structure limits, clutch
The space that friction plate diameter can strengthen is very limited, the most often uses the method strengthening disk spring thrust to improve clutch
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 reduces the handling comfort of tractor.
Summary of the invention
For problem present in background technology, the tractor clutch that the invention provides a kind of band hydraulic booster is handled
Mechanism, can not only strengthen the coefficient of torque reserve of clutch, and have good handling comfort.Do not destroy the machine of former car
Tool clutch, when not having hydraulic pressure, mechanical clutch can also use as usual, and clutch is played double protection.
The present invention adopts the following technical scheme that
A kind of tractor clutch operating mechanism of band hydraulic booster, including the clutch pedal being arranged in driver's cabin and
Play the booster of power-assisted effect, it is characterised in that: the front end of described clutch pedal is clutch pedal rocking arm, described clutch
Connect in pedal rocker arm and have return spring and connect fork；
Described booster is arranged on the top of clutch pedal rocking arm, the piston rod on described booster by connect fork with
Clutch separation pull bar connects.
Further, described booster piston bar is connected with the one end being connected fork, described clutch separation pull bar and company
The other end connecing fork is connected.
Further, on described booster, connection has oil inlet pipe and determines throttle orifice；Turning of described oil inlet pipe connection tractor
Delivery outlet stablized by monostable flow divider on constant flow pump output pipe, described determine throttle orifice and by oil hose and turns to constant flow pump
Fuel tank connects.
Due to the booster that is provided above at clutch pedal, power-assisted oil cylinder is turned to constant flow pump outlet tube by tractor
Road provides pressure, and the piston rod of booster is connected on clutch separation pull bar, when driver steps on clutch by connecting fork
During pedal, first provide power to the choke valve in power-assisted oil cylinder piston, make booster upper and lower cavity produce pressure differential, promote piston
Bar pulls clutch separation pull bar, makes clutch separation.
Relative to prior art, it is an advantage of the current invention that:
1. the present invention can not only strengthen the coefficient of torque reserve of clutch, and has good handling comfort.
2. the present invention does not destroy the mechanical clutch of former car, and 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, considerably increases the handling comfort of tractor.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described:
The tractor clutch operating mechanism of a kind of band hydraulic booster as shown in Figure 1, including being arranged in driver's cabin
Clutch pedal 1 and the booster 4 playing power-assisted effect, it is characterised in that: the front end of described clutch pedal 1 is clutch pedal
Rocking arm 10, described clutch pedal rocking arm 10 connects and has return spring 2 and connect fork 3；Described booster 4 is arranged on clutch
The top of pedal rocker arm 10, the piston rod 7 on described booster 4 is connected with clutch separation pull bar 9 by connecting fork 3.Described
The piston rod 7 of booster 4 is connected with the one end being connected fork 3, described clutch separation pull bar 9 and the other end phase being connected fork 3
Even.Connect on described booster 4 and have oil inlet pipe 5 and determine throttle orifice 6；What described oil inlet pipe 5 connected tractor turns to constant flow pump defeated
Go out the monostable flow divider on pipeline and stablize delivery outlet, described determine throttle orifice 6 and connected with turning to constant flow pump fuel tank by oil hose.
At oil inlet pipe 5, it is provided with choke valve 8 simultaneously.Described clutch separation pull bar 9 connects clutch linkage, and (described clutch divides
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 turning to constant flow pump to export is worn
Cross booster 4 to return to turn in constant flow pump fuel tank.When driver tramples clutch pedal 1, choke valve is first made to close, generation
Pressure differential produces thrust to the piston of power-assisted oil cylinder 4, by control, the pedal force of clutch pedal 1 can be controlled choke valve and close
The size closed and the Extraction rate determining throttle orifice 6, and then control cavity pressure；Piston rod 7 is promoted to move, and then by being connected to
The fork that connects on piston rod 7 drives clutch separation pull bar 9 to realize the separation of clutch.
When driver stops action, 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 clutch pedal 1 applies pressure again, power-assisted oil cylinder 4 just repeats above-mentioned action, plays power-assisted and makees
With.When driver's engagement the clutch 1, clutch pedal 1 return under the effect of return spring 2, choke valve 8 opens,
Under the effect determining throttle orifice 6, whole cavity produces certain pressure, forces piston rod to discharge and reset, and now clutch starts knot
Close, and by controlling lifting speed and can controlling the openings of sizes of choke valve 8 of clutch pedal 1, and then control clutch knot
The speed closed.
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 the spirit or essential attributes of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter
From the point of view of which point, all should regard embodiment 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 by fall in the implication of equivalency and scope of claim
Change is included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
May be appreciated other embodiments.
