As shown in Figure 4, this easy control device is fixing on the fixed plate that clutch outer member stretches out.
Working principle of the present invention is as follows:
As shown in Figure 1: when its during in free state, promote two air chambers to top dead center by the elastic force of spring 13, big elastomer diaphragm (9) is close to little platen (3), restriction post (5) is close to little air chamber cover (4).Push rod holder (14) has certain clearance (size is adjusted by the holder adjusting screw) with clutch release fork.
As shown in Figure 5: when clutch control valve is opened big or small air chamber pressurized air valve simultaneously when vehicle starting or gear shift, the exhaust valve closure of eliminating the noise simultaneously, the 2 air chambers generation thrust that expands rapidly, promote clutch and separate (this moment, little air chamber did not play a driving role) fully, the engine power transmission is cut off fully.After hanging up gear, control valve stops to the also rapid exhaust of atmospheric air chamber air feed (as then not exhaust of control valve of noise elimination exhaust, and open noise elimination outlet valve D), atmospheric air chamber thrust disappears, clutch spring power is pushed into as shown in Figure 6 position to atmospheric air chamber rapidly, this is the actuated position of clutch half joint (spring force of clutch can not promote the working thrust of little air chamber, so travel of clutch suspends in this position) just, the automobile balance starting.If the loaded vehicle or the starting difficulty of going up a slope, the stingy chamber of proper handling control valve small amount of exhaust gas, stingy chamber appropriateness is loosening, and clutch power further increases, and vehicle is started to walk smoothly.As shown in Figure 1, after vehicle driving is steady, the whole exhausts of little air chamber, push rod thrust disappears, big or small air chamber return, clutch engages fully.
The noise elimination exhaust is to produce noise when reducing the atmospheric air chamber exhaust to establish (because of exhaust sound can influence driver's operation), can also improve the atmospheric air chamber reaction velocity simultaneously, makes control more reliable.The stingy constant pressure air containment that contracts is few, and exhaust sound is less relatively, so do not establish the noise elimination exhaust of stingy chamber.
