Title:
CENTRAL RELEASE MECHANISM FOR ACTUATING A FRICTION CLUTCH
Document Type and Number:
WIPO Patent Application WO/2011/141012
Kind Code:
A3
Abstract:
The invention relates to a central release mechanism (15) for actuating a friction clutch, comprising a housing (10) for guiding an annular piston (9), which is accommodated in the housing and which is coupled to a throwout bearing (8), by means of the motion of which the friction clutch can be actuated, wherein the housing forms a pressure chamber (11) adjacent to the annular piston. Said pressure chamber is connected to a supply channel (12). Such a central release mechanism enables a more compact design, because the supply channel is radially inside the pressure chamber. The invention further relates to a friction clutch (1) having such a central release mechanism and to a motor vehicle having such a friction clutch.
