Abstract: A clutch actuation device includes two plates that can selectively extend and compress relative to one another to selectively engage or disengage a clutch. Each plate includes a plurality of grooves, each groove having a deep end portion, a shallow end portion, and a ramped or inclined surface between the end portions. Each groove on the first plate corresponds with a respective groove on the second plate to define a plurality of pockets. Within each pocket is an elongated member having a pair of curved ends and an elongated shaft therebetween. The curved ends sit in the deep end portions of the grooves. To extend the plates relative to one another, the first plate is rotated relative to the second plate. This causes the curved ends of the elongated members to pivot within the deep end portions, and the elongated shaft extends away from the ramped surface, separating the plates.

Abstract: The invention relates to a friction brake which can be used for a shaft and a bearing part that can be rotated in relation to each other about a rotational axis (3). The friction brake comprises two brake elements: the first brake element has a first friction surface (24) and has to be mechanically connected to the bearing part, and the second brake element has a second friction surface (25) and has to be mechanically connected to the shaft. The connectible and disconnectable dynamic effect of an actuation mechanism forces the two brake elements against each other during a braking action or stop in such a manner that the two friction surfaces (24, 25) rest one on the other and contact each other in the area of a contact surface (29, 30). The contact surface (29, 30) covers only a part of every friction surface (24, 25) at any point in time during a braking action or stop.
