A shift device for a change-speed gearbox, includes a shift rocker having sidewalls for axially displacing a shift sleeve positively connected to a gear wheel clutch or synchronizing unit. A shift finger is fixedly mounted on a shift shaft and positively engages a shift slot of the shift rocker to operate the shift rocker. The shift rocker is of single-piece configuration and made through a non-cutting process, with a blank being pre-punched from a steel sheet, before the blank is shaped into a finished product by at least one bending operation.

Shift rocker for a change-speed gearbox, and process of making a shift rocker

A shift device for a change-speed gearbox, includes a plurality of shift rockers, each shift rocker being supported in a pivot bearing and rotatable by actuating a shift finger, fixedly mounted on a shift shaft. The shift rockers are provided to axially displace respectively connected shift sleeves, whereby a locking unit is operatively connected via locking levers to the shift rockers to lock those shift rockers that are not activated. Each locking lever has one end of curved configuration which terminates in a cylindrical pin for engagement in a recess of the associated shift rocker, wherein the cylindrical pin is captivated within the recess of the shift rocker by impressing boundary regions of the recess.

Locking lever for a shift rocker

A shift rocker for use in a gear shift mechanism, includes a bracket of forked configuration, with the bracket having spaced-apart sidewalls in parallel relation for axially displacing a shift sleeve, and an arched cross member interconnecting the sidewalls. Connected to the cross member of the bracket for introduction of force is a rail which includes, directly or indirectly, a shift slot for engagement of a shift finger in fixed rotative engagement with a shift shaft, a latch contour for a separate stationary shift latching means, and a receiving member for engagement of a locking lever of a locking unit to inhibit a shifting movement of the shift rocker when the shift rocker is inactive.
