Title: ACTUATING UNIT FOR DRUM BRAKES
Abstract:
An actuating unit, in particular for use in a drum brake, having a sleeve, a pressure element and a force unit, wherein the sleeve has a bore with an internal thread, wherein the pressure element has a shaft with an external thread which can be brought into engagement with the internal thread of the sleeve, wherein the sleeve has an outer engagement region which can be brought into engagement with a force transmission element of the force unit, wherein the sleeve is arranged rotatably about a first axis relative to the pressure element, wherein rotation of the pressure element relative to the sleeve about the first axis brings about a shifting of the pressure element relative to the sleeve along the first axis, wherein, in an actuation mode of the force unit, the force transmission element transmits a torque, which acts about a second axis, to the sleeve in such a manner that the sleeve is caused to rotate relative to the pressure element, wherein the first axis is transverse to the second axis.
