Beschreibung
Zusammenfassung:The invention relates to an actuator (1) for an automated or automatic transmission, having a cylinder housing (3), a piston unit (2), and a piston rod (13), wherein the piston unit (2) is coupled to the piston rod (13) and is arranged movably in the cylinder housing (3) along an axial longitudinal axis (4), wherein the piston unit (2) separates from each other two pressure chambers (8, 9) of variable volume in the cylinder housing (3), by means of which pressure chambers the piston unit (2) can be loaded with compressed air on both sides, wherein the two pressure chambers (8, 9) are connected to a valve unit (14) which is able to switch the pressurization or purging of each of the two pressure chambers (8, 9), and wherein an end stop damping device for damping at least one end stop of the piston unit (2) is arranged in the actuator (1). In order to improve the end stop damping device, a pneumatically and a mechanically operating damping stage are provided.
