Abstract
Apparatus for synchronously shifting the reverse gear of a speed-changing transmission, such as an automobile transmission, includes an axially displaceable reverse shift gear which is rotatably mounted on a stationary shaft and cooperates (meshes) with a first gear on a first transmission shaft and a second, wider gear on a second transmission shaft. The reverse shift gear has a synchronizing device, provided with synchronizing cones and locking components, which becomes operative to brake the reverse shift gear with respect to a stationary element when the shift gear is axially displaced.
