Estimating the term…
A gear actuator for engaging and disengaging gears in an automatic manual transmission has a single working piston or two working pistons provided with a first working piston surface and a second working piston surface. An auxiliary piston is provided also. A pressure control valve controls a pressure supplied to the second working piston surface. A shut-off valve is provided. The first working piston surface and the pressure valve are supplied with a system pressure of a hydraulic system. The first working piston surface and the pressure control valve can be decoupled from the system pressure of the hydraulic system by the shut-off valve.
Gear actuator for engaging and disengaging gears in an automatic manual transmission, comprising a first working piston surface (2), a second working piston surface (4), an auxiliary piston (6), and a pressure control valve (7) which controls the pressure for the second working piston surface (4), wherein the first working piston surface (2) and the pressure valve (7) are supplied with a system pressure (Psy), and wherein the first working piston surface (2) and the pressure control valve (7) can be decoupled from the system pressure (Psy) by a shut-off valve (8).
