CLUTCH STRUCTURE

·As picture below, the clutch is dry diaphragm with single leaf. It consists of clutch driven
disk (2), release disk (4), intermediate disk (6), pressure plate (7) and flywheel (1).
·There are diaphragm springs in the pressure plate (7), which are fixed in the crankshaft by
intermediate disk (6) and bolt (5). Driven disk (2) is pressed on the flywheel (1) by
pressure plate (7), and bolt (8) is used to fix pressure plate (7) and flywheel (1) together;
the clutch pusher (9) is used to push separator disk (4) and then the separator disk (4) to
push the small end of diaphragm springs on pressure plate (7).

OPERATING PRINCIPLE OF CLUTCH

·As picture below, Picture a presents the connection status of clutch. When clutch pedal is
not treaded, the driven disk (3) is pressed on flywheel (2) by diaphragm spring (1). Driven
disk (3) and flywheel (2) are revolving synchronously, and the torque is transmitted to the
transmission-axle (6) by Separator disk (5) through driven disk (3).
·Picture b presents the disconnection state of clutch. When the clutch is treaded, pusher (4)
pushes separator disk (5) which presses the small end of diaphragm spring (1) to move the
big end of diaphragm spring (1) away from driven disk (3), so the pressure is disengaged
between driven disk (3) and flywheel (2) and the clearance is generated to cut off the
motive power of engine and pass the transmission.
