125000320 - INTRODUCTION - CLUTCH
The clutch is the dry, single plate hydraulically operated type.DESCRIPTION
Introduction
The system consists of:
- a clutch pump (master cylinder) (1) fixed to the pedals which compresses the oil
- a connecting pipe (8) between the pump and the clutch operating cylinder
- an impulse damper (6) in the pipe
- a clutch operating cylinder (2) fixed to the gearbox
- linkage (7) operating the thrust bearing (3)
- a thrust bearing (3)
- a clutch drip tray (5) with diaphragm springs
- a clutch plate (4)
The hydraulic operation makes it possible to:
- reduce the transmission of vibrations to the passenger compartment due to the damping effect of the fluid
- improve the gradualness of the engagement due to a constant adjustment of the clutch pedal setting
- decrease the operating load on the clutch pedal.
Operation
Pump (1) operated by the pedal , transmits the pressure to the operating cylinder piston (2).The latter acts on the operating linkage (7) which ''pulls'' the thrust bearing (3) overcoming the action of the pressure plate springs.As a result, the clutch disc (4) is uncoupled from the flywheel.When the pedal is released, the action of the pressure plate springs returns the clutch disc in contact with the flywheel.
