Embodiment
Introduce concrete structure of the present utility model and working procedure in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model system architecture schematic representation.As Fig. 1, whole automatic clutch system comprises that mechanical connection is connected two-part with gas circuit.
When system does not work, the clutch-driven piston push rod is under the effect of preloading spring, withstand shift fork and release bearing is pushed up the diaphragm spring separation and refer to by shifting fork bar, because the active force of preloading spring is little, so release bearing just can not make the diaphragm spring distortion with separating the finger fluid-tight engagement.Friction plate under the impacting force effect of diaphragm spring with the engine flywheel fluid-tight engagement, therefore rotate with flywheel with friction plate generator coupled input shaft, motor and generator are in jointing state.
When system works, normally close valve A opens under the effect of drive circuit, pressurized gas enter the cylinder of clutch-driven piston through reduction valve, normally close valve A and normally open valve B from high pressure gas holder, piston is outwards motion under gas load, drives push rod and moves together, and push rod is passed to release bearing to power by shift fork, shifting fork bar again, because power is very big, the maximum spring force that has surpassed diaphragm spring, so release bearing can promote diaphragm spring and separate and to refer to makes the diaphragm spring distortion.Diaphragm spring is pulled away from flywheel with friction plate, makes and produces a fixed gap between the two, and the generator input shaft that flywheel just can not drive the back rotates, and motor and generator break away from, and motor just can starting under no load.
After engine start, under the situation that keeps normally close valve A to open, give normally open valve B energising, make it to close, then gas in pipeline is separated out before and after it.PWM wave control signal of supply and exhaust valve C this moment is controlled the frequency of its break-make and the time of at every turn opening, and just the gas slowly in the clutch-driven piston cylinder can be discharged.Push rod slowly retreats, and drives release bearing and slowly retreats, and diaphragm spring slowly recovers deformation, and friction plate also just slowly engages with flywheel.When gas drained in the cylinder, push rod, release bearing and friction plate were all got back to initial position, and motor and generator are in jointing state once more.With normally close valve A and normally open valve B outage, off position is got back to by system afterwards.
Fig. 2 arranges schematic representation for the utility model circuit system.As Fig. 2, normally close valve A, normally open valve B and outlet valve C are switch valves, need to drive with the 24V DC electrical source.The control signal of coming out from ECU is 12V, can't directly drive this three valves, again because outlet valve C break-make frequency can be very high, can not adopt traditional relay to drive, and the therefore unified low limit drive circuit that adopts is controlled this three solenoid valves.
Fig. 3 is the utility model control signal sequential chart, and the break-make situation of solenoid valve is shown in this sequential chart during system works.
