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.

Abstract: An operating system for a vehicle transmission has a shifting lever which, for the shifting between gear ratios, can be swivelled in one shifting channel respectively about a shifting axle essentially in the longitudinal direction of the vehicle and, for selecting between different shifting channels, can be swivelled in at least one selecting channel about a selecting axle essentially in the transverse direction of the vehicle. A motion transmission connects the shifting lever with at least one transmission control shaft of a vehicle transmission.

Abstract: An operating device for a motor vehicle transmission is described which has a shift lever which, for shifting between transmission ratios, is movably mounted on the motor vehicle. In particular, the shift lever can be shifted in a respective shifting channel about a shifting axis essentially in the longitudinal direction of the vehicle and, for selecting between different shifting channels, can be swivelled in at least one selection channel about a selection axis essentially in the transverse direction of the vehicle. A motion gearing connects the shift lever with at least one transmission control shaft of a motor vehicle transmission, in which case a motor vehicle transmission case is linked to the motion gearing. The shift lever is mounted on a vehicle-body-fixed vehicle part and, in a projection onto a shifting plane, the motion gearing consists of at least one parallelogram linkage.
