An arrangement for actuating a shift element of a gearbox includes a rotatably mounted and preloaded shift pawl () and a shift ring () with an outer toothing () and assigned to a gearbox element. A first end () of the shift pawl () is assigned to the outer toothing () of the shift ring () so as to lock or release the shift ring () in order to shift a gear stage, and a second end () of the shift pawl () is assigned to a shift gate () of a shift drum () that actuates the shift pawl (). The shift pawl () is operatively connected to at least one double torsion spring () in order to apply a preload force.

Assembly for actuating a shifting element of a transmission

An arrangement for actuating a shift element for a bottom bracket gearbox () includes a shift ring () rotatably mounted in a housing () and assigned to a gearbox component. A shift pawl () for locking or releasing the shift ring () is assigned to the shift ring () for shifting a gear stage. A support region mechanically reinforces the housing () and is provided at least along a contact region () between an inner wall () of the housing () and an outer circumference of the shift ring (). The contact region () is defined by reaction forces () acting when the shift ring () is locked.
