  • Patent number: 8627735
    Abstract: A transmission shift device is provided that includes, but is not limited to a shifting shaft, which is mounted so it is axially immovable and rotatable in a transmission shift housing and is mechanically connected to a shift lever. Furthermore, the transmission shift device includes, but is not limited to a selector lever, which is mounted so it is axially displaceable on the shifting shaft and is mechanically connected to a selector lever. The selector lever is held in a spring-elastic manner in a middle axial selection position on the shifting shaft by at least one spring element.

  • Patent number: 8402858
    Abstract: A gearshift device for a change-speed gearbox of a motor vehicle, includes, but is not limited to a gearshift lever guided movably between positions corresponding to different gears, on which a locking member is displaceable between a locking position in a first degree of freedom in which it blocks any movement of the gearshift lever from a forward gear position into a reverse gear position, and a release position in a first degree of freedom in which it allows movement from the forward gear position into the reverse gear position. The locking member on the gearshift lever is movable in a second degree of freedom between a normal position in which movement between release position and locking position is possible and an alignment position in which it fixes the gearshift lever free from play.

  • Patent number: 6719659
    Abstract: A transmission for a motor vehicle, such as a motor vehicle EVT, is configures so that the number of teeth of the first planet gear of the epicycloidal gear train, operatively connected to the output toroidal disks by the first sun gear, and of an output element of the epicycloidal gear train form a ratio not equal to one. The transmission ratio of the toroid variator can be varied in such a way, and the number of teeth of the first planet gear of the epicycloidal gear train and of an output element of the epicycloidal gear train are configured in such a way that an output shaft speed approximating zero can be selected according to the variator.
