Abstract
A compact overdrive for a four wheel drive vehicle has the overdrive gear on the main shaft (12) of the gearbox without additional space required in the transmission. The two speed drive has the main drive gear (16) of the transmission either coupled directly to the shaft or via a gearing. An axial slider (54) couples the gear (16) directly to a fixed gear (20) on the shaft, for direct drive, or drives via second fixed gear (26) and a small reduction chain using a layshaft (52) and a freely rotating overdrive gear (32) coupled back to the main gear by the slider. Synchromesh is included and the range of the four wheel drive is extended, with the overdrive operating for both two wheel drive and four wheel.
