  • Patent number: 8910761
    Abstract: A device and a method for the adaptive degradation of collision energy. A deformation element is provided which carries out a first motion in one direction for degrading the collision energy and undergoes tapering. In addition, an actuator system is provided which adjusts the tapering for the adaptive degradation as a function of a control signal. The actuator system is configured for a second motion in the axis of the direction of the first motion and for adjusting the tapering of the deformation element. As a result of the second motion, the actuator system is able to hold at least one die plate having a respective opening through which the deformation element is driven for adjusting the tapering. A number of die plates held by the actuator system is a function of the control signal. The die plates held in each case cause tapering of the deformation element.

  • Patent number: 8827053
    Abstract: 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. As a result a load is distributed to the roller elements in a more uniform fashion and the pressing force of the friction brake pad against a brake disc when the partial lining disc brake is actuated is distributed more uniformly and counteracts irregular pad wear.
