Description of drawings
Fig. 1 is the automatic control system for automobile clutch schematic diagram.
Fig. 2 is the structural representation of Clutch Control cylinder among Fig. 1.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the utility model is described in further detail:
In conjunction with Fig. 1, automatic control system for automobile clutch shown in Figure 2, formed by Clutch Control cylinder 1, push rod 2, piston rod 3, cylinder piston 4, oil cylinder piston 5, return spring 6, pneumatic on-off valve 7, hydraulic proportion valve/high-speed electromagnetic valve 8, source of the gas 9, ECU (Electrical Control Unit) 10, dirt-proof boot 11, plug 12 etc.
Clutch Control cylinder 1 is made of the pneumatic cylinder 1a that is positioned at the left side and the oil hydraulic cylinder 1b that is positioned at the right side.Piston rod 3 is positioned at Clutch Control cylinder 1.Be set with cylinder piston 4 and oil cylinder piston 5 on the piston rod 3, cylinder piston 4 is positioned at pneumatic cylinder 1a, two cavitys about pneumatic cylinder 1a is divided into; Oil cylinder piston 5 is positioned at oil hydraulic cylinder 1b, two cavitys about oil hydraulic cylinder 1b is divided into.In the right cavity of pneumatic cylinder 1a return spring 6 is housed, the right-hand member of push rod 2 is against the left end of piston rod 2, and the left end of push rod 2 links to each other with the clutch control arm.
Have pneumatic on-off valve interface 7a on the right cavity wall of pneumatic cylinder 1a, be used for installing pneumatic on-off valve 7.Have hydraulic proportion valve/high speed electromagnetic interface 8a on the sidewall of oil hydraulic cylinder 1b, be used for installing hydraulic proportion valve/high-speed electromagnetic valve 8.Also have two oil ducts on the sidewall of oil hydraulic cylinder 1b, hydraulic proportion valve/high-speed electromagnetic valve 8 links to each other respectively with two cavitys of oil hydraulic cylinder 1b by different oil ducts, and pneumatic on-off valve 7 and hydraulic proportion valve/high-speed electromagnetic valve 8 are by ECU (Electrical Control Unit) 10 controls.
Preferably, push rod 2 stretches in the Clutch Control cylinder 1 and the left end of piston rod 2 offsets, and Clutch Control cylinder 1 is provided with dirt-proof boot 11 in push rod 2 positions.Return spring 6 is preferably selected conical Compress Spring.
Working principle is as follows:
(1) clutch original state: pneumatic on-off valve 7 is closed, by ECU (Electrical Control Unit) 10 control hydraulic proportion valve/high-speed electromagnetic valves 8 guarantee oil hydraulic cylinder 1b about two cavitys be communicated with;
(2) clutch separation: pneumatic on-off valve 7 is opened air inlet, piston rod 3 promotes push rod 2 to left movement, when treating that clutch just thoroughly separates, close simultaneously hydraulic proportion valve/high-speed electromagnetic valve 8 and pneumatic on-off valve 7, pneumatic on-off valve 7 exhausts this moment, the left chamber of pneumatic cylinder 1a produces resistance and stops clutch to continue to separate, and makes clutch keep current location;
(3) clutch combination: pneumatic on-off valve 7 exhausts, 8 beginnings of hydraulic proportion valve/high-speed electromagnetic valve are still closed, oil cylinder piston 5 motion that begins to turn right, the right chamber of compressing oil hydraulic cylinder 1b, the oil pressure in the right chamber of oil hydraulic cylinder 1b is greater than left chamber oil pressure, change oil hydraulic cylinder 1b right chamber oil pressure by ECU (Electrical Control Unit) 10 control hydraulic proportion valve/high-speed electromagnetic valves 8 this moment, reaches the speed combination of clutch.
The hydroelasticity modulus is 2.1X10MPa; the air Young's modulus is 1.4X10MPa; the compressibility of air is compared liquid compressibility and is almost ignored; so just can guarantee piston rod 3 stop motions as long as hydraulic proportion valve/high-speed electromagnetic valve 8 begins action, reach the accurately purpose of control of clutch position.
