Claim Text:
1. A variable track width vehicle axle comprising an outer axle casing which supports two drive shafts which are driven at their inner ends by a planetary drive gear and a carry wheel attachment flange at their outer ends, each drive shaft including first and second parts which are in screw-threaded engagement with each other so that rotation of one part relative to the other changes the effective length of each shaft and thus the track width of the axle, a first member of the planetary gear driving the first part of each drive shaft, and a clutch collar which in a first position connects said two parts of each shaft to prevent relative rotation and in a second position disconnects said two parts of each shaft to allow relative rotation therebetween and connects the second part of each drive shaft to a second member of the planetary gear so that when the drive gear is driven the first and second parts are rotated relative to each other to change the effective length of each drive shaft.
