Abstract: A shifting rocker (2) for a transmission comprises two arms (4, 6), between which a mount for a sliding sleeve is provided. The shifting rocker (2) is mounted in a transmission housing at two bearing points (20, 22) such that it can pivot.

Abstract: In a shifting assembly for a multiple-gear variable speed motor vehicle transmission, a central selector or shifting shaft (2) is mounted in the transmission housing (12) such that it can be rotated and displaced axially. By rotating the selector or shifting shaft (2) a coupling to be actuated in a shift gate can be selected, and by subsequently axially displacing the shaft, the gears can be engaged. At least two roller arms (4), spaced somewhat from one another, are positioned on the selector or shifting shaft (2), bearing a rod (6) between them. The rod (6) is mechanically linked with a contoured element or lever (16) that is mounted in the transmission housing (12) such that it can swivel. The contoured edge (20) of the contoured element or lever (16) mirrors the selection patterns and is spring loaded against the rod (6) by a spring element (18).

Abstract: A shifting device for a transmission, in which at least one gearshift package is allocated to two non-successive gears and each of these gearshift packages is coupled with a gearshift lever. An H- or a multiple H-shifting diagram is allocated to the gearshift lever, in which the gears that can be selected within a gearshift path are allocated to different gearshift packages. The gearshift lever and the gearshift packages are connected to a conversion device with which a gearshift lever movement to take out a previous gear in a gearshift path causes this gear to be taken out in a first gearshift package. A gearshift lever movement for putting in the new gear in the same gearshift path, a second gearshift package puts in this new gear. The conversion device functions in such a way that the gearshift lever is coupled with an axially displaceable and radially pivotable shift finger shaft.
