Electromechanical actuating drive

摘要

An electromechanical actuating drive is described which has an electrical actuating motor to which an electrical control variable is supplied on the input side and which is connected via a play-free, low-mass step-down transmission to a mechanical actuating arm. The actuating drive furthermore has a mechanical actuating element which engages on the step-down transmission in such a manner that its displacement is transmitted directly to the actuating arm, so that the actuating arm can be driven independently of, and uninfluenced by the operation and actuation of the actuating element.
