20080271554 | Device for the rotationally fixed connection of a shaft to at least one component mounted to rotate on the shaft - A device for connecting, in a rotationally fixed manner, a shaft to at least one component which is rotationally supported on the shaft, such as a gear wheel of a gear in a transmission. The device includes an actuating element that is rotationally fixed, but axially slides on the shaft, such that when the element is actuated by an actor, the element actively, frictionally communicates with the component to at least approximately equalize a rotational speed difference, between the component and the shaft. The actuating element can be actuated by the actor with a force to frictionally connect the component to the shaft in a rotationally fixed manner. The device further includes a holding device, which retains the actuating element in a shift condition essentially equivalent to the rotationally fixed condition of the component without further actuation of the actor. | 11-06-2008 |

20090301248 | DEVICE FOR ACTUATING A GEARWHEEL, WHICH IS DESIGNED AS A LOOSE WHEEL, OF A TRANSMISSION DEVICE - A device for actuating a gearwheel of a transmission device. The gearwheel rotates on a shaft and can be shifted by way an engagement mechanism that includes at least one actuator that is arranged at least partially inside the shaft. The actuator can be actuated by a pressure medium to fix the gearwheel to the shaft. The actuation force required for engaging or disengaging the gearwheel can come from within the shaft. The actuator is a piston-cylinder unit which is either rotationally fixed to the shaft or rotationally fixed relative the shaft. When the actuator is rotationally fixed relative to the shaft, the active connection between the actuator and the gearwheel, which is to be shifted, includes a drive decoupling unit between the actuator and the shaft. | 12-10-2009 |

20100051405 | DEVICE OF A ROTATIONALLY FIXEDLY CONNECTING A SHAFT TO A COMPONENT WHICH IS ROTATABLY MOUNTED ON THE SHAFT - A device for rotationally fixing a shaft to a component that is rotatably arranged on the shaft. The actuating element positively engages the components to rotationally fix the components to the shaft. The difference in rotational speeds, between the component and the shaft, can be at least approximately compensated for by the actuating element. The actuating element, for rotationally fixing the component to the shaft by the actuator, is operatively connected to at least one support body, which is rotationally fixed with respect to the shaft in such a manner that the actuating element can act upon the component with an actuating force that depends on the torque to be transmitted from the shaft to the component and which is independent of the actuation of the actuator in the state in which the actuating element can be rotated relative to the shaft. | 03-04-2010 |
