Spring-loaded brake actuator

Abstract

A spring-loaded brake actuator includes a push rod that can be coupled to a braking element of a brake, an energy accumulator which is designed to apply a braking force onto the push rod via a coupling mechanism, a drive, which is designed to hold the push rod in a brake release position against the force of the energy accumulator, and an auxiliary release device, with which the transmission of the braking force from the energy accumulator to the push rod can be blocked independently of the drive, in which the coupling mechanism has two coupling members which are in engagement with one another via a claw clutch, and in that the auxiliary release device has an actuating element which is designed to bring the claws of the claw clutch into a non-engaged position in a direction of movement transverse to the force transmission direction.
