Patent ID: 7398866

Claim:
A self-boosting friction brake, having a friction brake lining, having a contact-pressure element with which the friction brake lining, for generating a braking force, can be pressed against a rotatable brake body, the contact-pressure element being movable in a direction of rotation of the rotatable brake body and being braced on a buttress at a support angle to a normal of the rotatable brake body, and when the friction brake is actuated the rotatable brake body exerts a frictional force on the friction brake lining that urges the contact-pressure element in the direction of an increasingly strong contact pressure, and having an actuating device with which the contact-pressure element is movable in and counter to the direction of rotation of the rotatable brake body, characterized in that the support angle (α) is selected such that a brake parameter C* of the friction brake ( 10 ) is located substantially at a pole point.
