Abstract
An actuating device for machine elements that are subject to wear play, especially for brakes of railborne vehicles. The actuating device has a piston-cylinder unit operated by a pressure medium. The piston-cylinder unit has a piston rod engagable with an adjusting device configured as an adjusting nut/spindle assembly, for wear play compensation. The adjusting nut/spindle assembly has a sleeve-type adjusting nut with external toothing engagable with an automatically actuatable actuating drive. An electronic control unit generates an actuating signal for wear play compensation in dependence on the position of a brake piston connected to the piston rod. The brake piston position is measured by a sensor. The actuating signal is transmitted to the actuating drive.
