With the development of auto industry, mechanical automatic gearbox (AMT) turns into current China's gearbox automatic technology
During the important directions of advance, the especially automatic improving for the manual transmission that the country is largely equipped on heavy load truck,
Play very important effect.Automatic speed changer for machine is the application on the basis of traditional fixed shaft transmission and clutch
Electronic technology and fluid drive are theoretical, and with electronic control unit (TCU) for core, the separation of clutch is controlled by execution system
With engaging, shifting operates and the regulation of engine throttle, to realize the automatic manipulation of starting, gearshift.
Mechanical automatic gearbox AMT system to the control for selecting gear shift and clutch by realizing moving certainly for vehicle
Shelves, but when AMT system breaks down, vehicle will be unable to separate clutch, lose maneuverability.Come for some special vehicles
Say, emergency function is vehicle necessary functions.Retrieve Patents both domestic and external, it is only a kind of by way of Pneumatic booster come real
The emergency flight control of existing vehicular clutch, the device need vehicle to provide pressurize source of the gas, have significant limitation in use.
The present invention uses the scheme of hydraulic hand-pump, former AMT system executing agency is not modified, and only need to increase by one
The hydraulic valve block of integrated hydraulic valve and manual pump is the emergency maneuver function that vehicular clutch can be achieved, and is from engineering actual angle
The design of AMT system emergency function provides an effective solution.
The content of the invention
Present invention solves the technical problem that it is to provide a kind of mechanical automatic gearbox AMT Manual clutchs emergency maneuver dress
Put.The present invention is a kind of AMT Manual clutchs emergency maneuvering device, realizes that vehicle exists by Manual clutch emergency maneuvering device
Clutch separation and combination during AMT system failure, can be widely used in the AMT system improvement and design of various vehicles.
The technical scheme is that:A kind of AMT Manual clutchs emergency maneuvering device, by manual pump, shuttle valve, with reference to electricity
Magnet valve, check valve, choke valve and controlling switch etc. form;Described controlling switch is used to control the confession with reference to magnetic valve, power-off
State, the disconnection with reference to magnetic valve, connectivity capabilities are realized respectively;The inlet port of manual pump is connected with system fuel tank, oil-out with
Check valve oil inlet connects, and the oil-out of check valve is divided into two-way:The import with combining magnetic valve is connected all the way, with reference to magnetic valve
Outlet connection choke valve after be connected with system fuel tank;The another way of the oil-out of check valve and shuttle valve oil inlet connect
Connect, the outlet of shuttle valve is connected with clutch actuating mechanism;Described choke valve has throttle orifice.
In emergent separation clutch, manual pump is manipulated, hydraulic oil promotes clutch actuating mechanism separation clutch, needed
When combining clutch, to combining with reference to solenoid valves, clutch, by adjusting the restriction size of choke valve, can adjust
Save clutch combination speed.
The effect of the present invention:This mechanical automatic gearbox AMT Manual clutch emergency maneuvering device principles are simple, are easy to
Control system is controlled, and the clutch point of mechanical automatic gearbox can be easily realized in AMT system failure or special operation condition
From with combination.The device overcomes demand of the pneumatic clutch emergency control to pressurize source of the gas, from engineering actual angle solution
The emergency maneuver function of AMT system of having determined clutch, the system that various mechanical automatic gearboxes (AMT) can be widely used in
In design.
Brief description of the drawings
Fig. 1 is AMT Manual clutch emergency maneuvering device fundamental diagrams;
1. the manual choke valve 4. of 2. check valve of pump 3. combines the controlling switch of 5. shuttle valve of magnetic valve 6.
Embodiment
A kind of AMT Manual clutchs emergency maneuvering device of the present invention, by manual pump 1, shuttle valve 5, with reference to magnetic valve 4, list
Formed to six parts such as valve 2, choke valve 3 and controlling switches 6.
Described manual pump 1 is used for the emergent fuel feeding of device;Described shuttle valve 5 be used for clutch actuating mechanism meet an urgent need fuel feeding with
The oil circuit switching of normal fuel injection;The emergent combination that described combination magnetic valve 4 is used to control clutch is with separating;Described is unidirectional
Valve 2 is used for the pressurize for controlling manual oil pump feed;Described choke valve 3 is used for the combination speed for controlling clutch;Described control
Switch 6 is used to control the confession with reference to magnetic valve 4, off-position, realizes combine the control function that magnetic valve 4 disconnects, connected respectively;
The inlet port of manual pump 1 is connected with system fuel tank, and oil-out is connected with the oil inlet of check valve 2, and the oil-out of check valve 2 is divided into two
Road:The import with combining magnetic valve 4 be connected all the way, with reference to magnetic valve 4 outlet connect choke valve 3 after be connected with system fuel tank;
Another way is connected with an oil inlet of shuttle valve 5, another oil inlet and the clutch control valve oil-out in original system of shuttle valve 5
It is connected, the outlet of shuttle valve 5 is connected with clutch actuating mechanism.
This AMT Manual clutch emergency maneuvering devices function is realized as follows:
A) during AMT system normal work
Clutch control oil enters the oil inlet of shuttle valve 5 one through former clutch control valve outlet, promotes the valve element of shuttle valve 5 to close another
One oil inlet (left end oil inlet in figure), control oil enter clutch actuating mechanism from outlet, realize that clutch normally separates.When
With reference to when, control oil from clutch actuating mechanism enters shuttle valve 5, then passes through former clutch control valve from 5 former oil inlet of shuttle valve
Off-load, realize that clutch normally combines.
B) when AMT system does not work, the realization of clutch separation
When AMT system does not work, clutch separation action request, MT Manual clutch emergency maneuvering device work(of the invention
Can realize it is powered with reference to magnetic valve 4, cutting system oil return, then manually the pump oil of pump 1, hydraulic oil are entered by check valve 2
Enter the oil inlet of shuttle valve 5 one (left end hydraulic fluid port in figure), promote the valve element of shuttle valve 5 to close another oil inlet (with clutch control in original system
What valve oil-out processed was connected), control oil enters clutch actuating mechanism from outlet, realizes the emergent separating action of clutch.
C) when AMT system does not work, the realization of clutch combination
When AMT system does not work, when clutch is in released state, AMT Manual clutchs emergency maneuver of the invention dress
Put function and realize powered off with reference to magnetic valve 4, open system oil return path, control oil is driven in clutch diaphragm spring
Under clutch actuating mechanism piston effect, enter shuttle valve 5 from clutch actuating mechanism, then by 5 former oil inlet of shuttle valve (with original
Clutch control valve oil-out is connected in system) into magnetic valve 4 is combined, finally enter the throttling by one-way throttle valve 3
Hole off-load, the combination of clutch is realized, by adjusting the throttle orifice size of choke valve 3, can control the speed of clutch combination, it is real
The steady combination of existing clutch, vehicle gentle start.
