Abstract

The present invention provides a multi-speed transmission unit comprising a first gear (5) drivable to rotate at a first speed, a second gear (9) drivable to rotate at a second speed and a shaft (2). The first (5) and second (9) gears are mounted on the shaft (2) and are rotatable relative thereto. Engagement means (3, 4, 7) is provided operable to lock each gear (5, 9) separately to the shaft (2). The engagement means comprises a locking member (3) which is moveable radially into and out of the shaft (1) and actuating means (1, 7, 4) operable to move the locking member (3) radially outwardly from the shaft (2) to engage one of the first (5) and second gears (9) and radially inwardly into the shaft (2) to disengage an engaged gear (5; 9).
