4.1.1 CLUTCH
4.1.1.1 HYDRAULIC CLUTCH ACTUATION LAYOUT (1.3 QUADRAJET)
Constructional specifications:
The clutch is single dry plate type, with a thrust
bearing in permanent contact with the pressure
spring.
The driven plate is driven by pressure exercised
by a diaphragm spring. The clutch release takes
place via the hydraulic system operated by the
pedal. Friction materials free from non-
environmentally friendly components have been
adopted; special care has been taken in the
development of new materials and the clutch
assembly with a view to guaranteeing excellent
performance in terms of modulation and driving
comfort with a consequent reduction in weight
compared with traditional hydraulic operation.
The clutch master cylinder has undergone
considerable improvements compared with the
components used normally; it comprises:
- Plastic casing which makes a further contribution
to a reduction in the weight;
- Steel cylinder;
- Plastic material piston.
The material for the piston and the rubber seals
have been specially developed for operating with
long strokes; in addition, the seal produced by the
rubber steel contact is excellent compared with
traditional type clutch pumps where the seal is on
cast iron.
