ABSTRACT:
The invention relates to a clutch disc with vibration damper, in which a driven plate carrying the friction linings is arranged between two cover plates firmly connected with the hub. Friction rings are arranged between the driven plate and the cover plates. The axial force generation for the achievement of a friction force is effected through externally situated leaf springs which extend radially between individual helical springs. The leaf springs are riveted fast at their radially inner ends with the hub and with their outer ends they press through distance pieces upon a presser plate which is situated between the one cover plate and the one of the friction rings. The presser plate is arranged fast in rotation but axially displaceably in relation to the pertinent cover plate. Tabs bent off axially on the external circumference of the presser plate here engage in corresponding recesses of the cover plate. Especially with regard to heavy working in freight vehicle clutches thus the presser plate is loaded only with the transmission of the friction force, and in combination with the preferably three axially protruding tabs the production of the presser plate is simple, likewise uniform distribution of the torque to all three tabs is guaranteed. Thus at this point too, the wear is reduced to a minimum.
