Abstract: A mechanism with a transmission device for supplying at least one auxiliary power take-off aggregate of a vehicle with drive energy. A transmission ratio of the transmission device is varied continuously varied at least over a certain range and the transmission device can be brought into functional connection, on the input side, with a drive input of a drive machine of a drive-train of the vehicle and, on the output side, with the auxiliary power take-off aggregate. The transmission device is in the form of a mechanical transmission device. A transmission unit is provided in the power path between the drive machine and the auxiliary power take-off aggregate, whose transmission ratio is adapted to the mechanical transmission device in such manner that, in a main operating range, the mechanical transmission device can be operated essentially within the range of its maximum efficiency.

Abstract: An actuator for the drive train of a motor vehicle for the automation of a manual gearbox. The invention is characterized in that the actuator is produced from an electrostrictive material.

Abstract: The invention concerns an automated transmission, for example a multi-stage motor-vehicle shift transmission, with at least one controllable actuating drive provided as a gear actuator (26) to engage and disengage a gear of the transmission or as a clutch actuator (7) to engage and disengage an associated automated engine clutch, and an automated friction clutch, for example an automated engine clutch arranged in the drivetrain of a motor vehicle between a drive engine and a transmission, with a controllable actuating drive provided as the clutch actuator (7) for engaging and disengaging the friction clutch. To improve the controllability and achieve a longer service life while reducing production costs, it is proposed to use as the actuating drive (7, 26) a pneumatic muscle (8, 8.1, 8.

Abstract: A shift device for a transmission with a cam drive, which has a shifting roll, which is guided to be rotatable about an axle, as well as selector fingers, which engage themselves in grooves and are controllingly conducted therein. On the outer circumference of the shifting roll are rocker elements (8) with wedge-shaped tips at both ends. The rocker elements are rotatably supported on an axle (6) in such a manner that the tips can engage themselves in corresponding grooves in the shifting roll. To this purpose a compression spring (9) is provided. Upon rapid turning of the shifting roll, the effect of the engendered centrifugal force is such that the tips are no longer engaged in the grooves.

Abstract: A device for the suspension and for roll stabilization of motor vehicles achieves the required roll stiffness as well as the required lift stiffness without any additional springs by coordinating the ratio of the piston areas to the piston ring areas of the spring cylinders with simultaneous active engagement by an actuator integrated between the cross-wired lines.
