According to the invention, the friction brake is equipped with a linear drive, for example an electromagnet, for brake actuation. The self-energizing device converts a friction force exerted by a rotating brake body on a friction brake lining during braking actuated by the linear drive of an actuation device into a second contact pressure that presses the friction brake lining against the brake body in addition to the first contact pressure exerted by the actuation device. The self-energizing device provides a non-proportional characteristic magnetic force curve of the electromagnet of the linear drive. | 11-20-2008 |
| 20080296102 | Self-Amplifying Electromechanical Partial Lining Disc Brake - The present invention relates to a self-amplifying electromechanical partial lining disc brake, having a ramp mechanism as a self-amplification device. According to the invention, a rack for driving a friction brake pad is situated between roller elements of the ramp mechanism, particularly at a geometrical centroid of an imaginary surface defined by the roller elements.
