  • Actuating unit
    Patent number: 6767305
    Abstract: An actuating unit for use on an electromechanically actuated disc brake for automotive vehicles including a drive unit or an electric motor, an actuating element for actuating one of two friction linings displaceably arranged in a brake caliper, and a first and a second reducing gear. The first reducing gear is comprised as a ball screw, while a planetary gear is used as the second reducing gear. To increase the efficiency, the present invention discloses a coupling shaft used to transmit forces from the planet cage of the planetary gear to the threaded spindle of the ball screw. The ends of the coupling shaft form universal joints with the planet cage and the threaded spindle.

  • Actuating unit for an electromechanically actuated disc brake
    Patent number: 6752249
    Abstract: An actuating unit for an electromechanically actuated disc brake for automotive vehicles which is composed of a drive unit or an electric motor, an actuating element forming one of two friction linings into engagement with a brake disc, and a reducing gear. A freewheel mechanism that interacts with the electric motor has the function of a parking brake. In order to ensure a high level of reliability in operation of the parking brake and to render it resistant to external influences, in particular, oscillations or vibrations, the present invention suggest that the freewheel mechanism be configured in such a way that its clamping effect is produced by a form-locking torque transmission and that, in its actuated state, it prevents a rotational movement of a bearing in which the rotor of the electric motor is mounted.

  • Actuating unit with a threaded pinion, aplanetary gear and actuating element influenced thereby
    Publication number: 20030050147
    Abstract: The present invention discloses an actuating unit for use on an electromechanically actuated disc brake for automotive vehicles which is basically composed of a drive unit (1) or an electric motor (11), an actuating element (7) by means of which one (4) of two friction linings (4, 5) displaceably arranged in a brake caliper is moved into engagement with a brake disc (6), and a first and a second reducing gear (2, 3). The first reducing gear (2) is provided as a ball screw (16-18), while a planetary gear (30-34) is used as the second reducing gear (16-18).
