Title:
FRICTION CLUTCH AND ACTUATOR THEREOF
Document Type and Number:
WIPO Patent Application WO/2004/104443
Kind Code:
A2
Abstract:
The invention relates to a friction clutch consisting of primary and secondary disks (2,3) and a pressure plate (4) and having an actuator with two coaxial rings (11, 12) that can be rotated independent of one another, said rings compressing the disks (2, 3) during a relative rotation. In order to provide an actuator which operates accurately and with zero loss, an electric motor (18) having at least one drive wheel (20) is provided for the relative rotation of both rings (11,12), said drive wheel being drivingly connected to the two rings (11, 12) by traction means (21). Two chains (22, 23) of the traction means (21) lead from the drive wheel (20) to the rotatable rings (11,12), wherein the ends of the chains (22,23) are fixed to their corresponding ring (11,12) and the two rings (11,12) have different diameters.
