Shift mechanism avoiding neutral during engagement of reverse gear

摘要

The gear shift device has several shift fork bridges (e.g. 17) capable of relative axial motion on an axially movable shift rod (13), causing a shift pin to act on a shift shaft. A bolt (22) is fitted on the shift rod, about which pivots an angled lever (23). One arm (24) of the lever engages with the shift rod via a bolt-fork connection (25, 26). The other arm of the lever is supported via an arc slot and bolt connection (28, 29) on a fixed point (14) in the casing, so that a movement of the bridge to engage fifth gear carries the shift rod with it. A movement of the bridge to engage reverse gear holds the shift rod in a fixed position but turns a rocker (34) to engage reverse gear.
