An actuator arrangement for a motor vehicle drivetrain, in particular for a dual-clutch arrangement. A first fluid cylinder is connected via a first fluid connection to a fluid supply device. A second fluid cylinder is connected via a second fluid connection to the fluid supply device. A pressure measuring arrangement has a single pressure sensor which is connected by means of a connecting arrangement to the first fluid connection and to the second fluid connection.

Actuator arrangement for a motor vehicle drivetrain, with control method for the same

An actuator arrangement for a motor vehicle drive train which has at least one friction clutch for transmitting drive torque, in particular in the form of a starting clutch, as well as a gearbox having at least two gears, which can be engaged and disengaged by means of a shift clutch arrangement. The actuator arrangement comprises a hydraulic circuit that has a pump driven by means of an electric motor; a clutch hydraulic cylinder by means of which the friction clutch can be actuated; and a shift actuator device for actuating the shift clutch arrangement. The shift actuator device has a shift drum which is or can be coupled to the electric motor via a shift drum coupling device in a manner such that the shift drum can be set in rotation by means of the electric motor in order to actuate the shift clutch arrangement.

Actuator arrangement for a motor vehicle train

Fluid cylinder for activating an element of a drivetrain of a motor vehicle. The fluid cylinder has a cylinder housing and a piston. The piston is sealed off from the cylinder housing by means of a piston seal. At least one fluid chamber is formed between the cylinder housing and the piston, which fluid chamber can be connected via at least a first fluid connection to a fluid supply device. The piston in a piston stop position rests against a stop surface of the cylinder housing. The first fluid connection is formed in the region of the stop surface of the cylinder housing. The piston is connected to a sealing device which seals off the first fluid connection in the piston stop position.

Drivetrain-clutch arrangement and fluid cylinder therefor

Actuator arrangement for a drive train. The actuator arrangement has an actuator pump driven by electric motor, and a clutch actuator, which is designed for actuation of a friction clutch of the drive train and which is connected to a discharge port of the actuator pump. The actuator arrangement has a parking lock actuator, which is designed for actuation of a parking lock arrangement of the drive train. The parking lock actuator has an open position, in which the parking lock arrangement is released, and a closed position, in which the parking lock arrangement is closed. The parking lock actuator is likewise connected to the discharge port of the actuator pump. The parking lock arrangement can be retained in at least one of the open position and the closed position by means of a retaining device.
