Abstract: An oscillation decoupling system does not transmit oscillations, for example, from a drive train of a vehicle to an actuator system for a clutch. A clutch system with the oscillation decoupling system has an adjusting element. The actuator system includes an active element which is designed to carry out an active movement in a predetermined working direction and an element of the oscillation decoupling system which connects the active element to the actuator device and to the adjusting element. The element of the oscillation decoupling system includes, in a predetermined direction of work, a play region in which the active element or the adjusting element moves without the respective other moving element.

Abstract: A self-adjusting clutch actuator includes a transmission element displaceable in a displacement direction; and a compensation mechanism having a piston displaceable in the displacement direction of the transmission element. The compensation mechanism allows a first relative displacement (X) of the transmission element relative to the piston in the displacement direction when there is no actuating force in the clutch actuator, and blocks the first relative displacement (X) when an actuating force is introduced into the clutch actuator by bringing a frictional element (4) into contact with a counter-element. The frictional element (4) is designed for a second relative displacement (Y) relative to the counter-element when the first relative displacement (X) is not blocked by the compensation mechanism (22).

Abstract: An electromechanical transmission and/or clutch actuator includes an electric motor for generating a driving rotational movement of a motor shaft, and elements for transmitting the driving rotational movement via a flexible drive from the electric motor to a spindle drive configured to convert the rotational movement to an axial actuation movement. The elements for transmitting the driving rotational movement may include a driving element such as a driving pulley or gear connected coaxially to the motor shaft, a driven element wheel such as a driven pulley or gear connected to the spindle drive, and a flexible element such as a drive belt which transfers the driving rotational movement from the motor shaft to the spindle drive.

Abstract: A device for speed-dependent braking torque control for electrical machines excited by permanent magnets includes a switching device deliberately short-circuits the electrical machine. The switching device is controlled as a function of an induced voltage generated by the electrical machine. If the induced voltage falls below a defined value, the switching device reverses the short-circuited state of the electrical machine to cause the braking torque to reduce to zero and the speed to increase again. The speed can thus be controlled within a range by alternately opening and closing the switching device.

Abstract: An anti-rotation safeguard of an axially moving element is provided with an anti-rotation safeguard, the anti-rotation safeguard being suited for use in a ball screw drive in an automated manual transmission. The ball screw has nut which rotates on balls on a spindle, at least one securing element protruding radially from the spindle, and at least one guide element with a longitudinal a groove which guides the securing element. During translation of the spindle, rotation of the spindle is prevented by the securing element in the guide element groove. The guide element is accommodated in a cutout of the ball screw drive enclosure and can rotate about its longitudinal axis so that force transfer from the securing element to the groove is over a large surface area to reduce wear of the groove and of the securing element.

Abstract: A gear-shifting mechanism for a transmission has a gear-shifting actuating unit with a gear-shifting actuator that can be moved along a gear-shifting actuating axis, and a selection unit that can be connected to the gear-shifting actuator. The selection unit has a selection element which is designed to adopt different positions in a direction that is non-parallel to the gear-shifting actuating axis, in order to be able to connect to different selector forks in the different positions, for moving transmission components for shifting gears, and a switching actuator having a switching actuator axis that defines a switching movement of the switching actuator for moving the selection element into the different positions. The switching actuator axis and the gear-shifting actuating axis are oriented such that they are parallel to each other.

Abstract: An actuating mechanism includes a transmission element configured to be displaced parallel to a transmission direction, an actuating element configured to perform an actuating movement to cause the displacement of the transmission element in the transmission direction, a conversion mechanism arranged between the transmission element and the actuating element which converts the actuating movement of the actuating element into the displacement of the transmission element, and a bracing element configured to introduce a pretension, preferably an elastic pretension, at least into the conversion mechanism. The invention also relates to a clutch actuator and a transmission actuator having an actuating mechanism in accordance with the present invention.

Abstract: A shift mechanism for a gearbox has a shift actuation unit designed to produce an axial shifting motion, at least two selector forks for shifting gear components to shift gears, and at least one shift rod designed to transmit the axial shifting motion from the shift actuation unit to at least one of the at least two selector forks. The coupling mechanisms and the shift rods are positioned to be axially aligned with one another.
