Abstract:
A rotary vibration reduction device for a motor vehicle for transmitting drive power from a drive machine to a drivetrain is provided. The vibration reduction device includes a primary and secondary connectors between the drive machine and drivetrain, and a coupling device between the primary connector and the secondary connector. The coupling device has a vibration reduction actuator with a piston chamber and has a piston element movable to generate a vibration reduction force in response to changes in working pressure in the piston chamber controlled by a pressure-generating device.

Claim (Index 15):
A method for starting a motor vehicle,\n the motor vehicle including a drive machine in the form of an internal combustion engine, a drivetrain configured to receive torque from the drive machine for transmission of drive power to at least one wheel of the motor vehicle, a primary connector between the drive machine and the drive train configured to receive the torque from the drive machine, a secondary connector between the drive machine and the drive train configured to output the torque from the first connector to the drivetrain, a coupling device between the primary connector and the secondary connector configured to transfer the torque from the drive machine from the primary connector to the secondary connector, the coupling device including a vibration reduction actuator with a coupling piston chamber, a further coupling piston chamber, and a coupling piston displaceably fluid-tightly separating the coupling piston chamber from the further coupling piston chamber, wherein the coupling piston chamber and the coupling piston are coupled to the primary and the secondary connectors such that a rotational movement of the primary connector relative to the secondary connector causes the coupling piston to be displaced counter to the vibration reduction force, the motor vehicle further comprising a pressure generating device fluidly coupled to the coupling piston chamber such that a working pressure in the coupling piston chamber is variable in response to pressure generated by the pressure-generating device, a further pressure generating device fluidly coupled to the further coupling piston chamber such that a working pressure in the further coupling piston chamber is variable in response to pressure generated by the further pressure-generating device, a pressure-balancing device fluidly coupled to the pressure-generating device such that a working pressure in the coupling piston chamber is variable in response to pressure generated by the pressure-generating device, a further pressure-balancing device fluidly coupled to the further pressure-generating device such that a working pressure in the further coupling piston chamber is variable in response to pressure generated by the further pressure-generating device, a first sensor configured to detect a rotational movement of the primary connector and a second sensor configured to detect a rotational movement of the second connector, wherein the coupling piston is configured to generate a vibration reduction force when loaded with a working pressure in the coupling piston chamber, the method comprising the act of: increasing the working pressure in at least one of the coupling piston chamber and the further coupling piston chamber to above a predefined threshold value such that the primary connector and the secondary connector are rotationally fixed relative to one another during an engine start.
