Abstract
A clutch comprises a flywheel which rotates with a first shaft, a friction disk which rotates with a second shaft, a clutch cover which rotates with the flywheel and a pressure plate which rotates with the cover. The flywheel is movable axially relative to the cover. An axially acting spring device bears on the cover and urges the pressure plate towards the flywheel to clamp the friction disk against the flywheel. The cover comprises a bearing surface, first and second parts rotatable relative to each other and a circumferentially acting spring device which resists any such relative rotation. The first part rotates with the first shaft and comprises a flange constituting a support flange for the clutch. The second part, against which the friction disk bears axially, comprises a plate constituting the reaction plate proper. Within this plate is a torque limiter comprising friction facings and an axially acting spring device for clamping up these friction facings. The torque limiter is operative between the plate and the bearing surface on the cover. The axially acting spring device associated with the friction disk is the same as the axially acting spring device associated with the friction facings of the torque limiter.
