Abstract
For free shifting in a multi-speed gear hub comprising a claw clutch, first and second springs are included for preloading a projecting claw part in mutually opposite directions. Preloading in the second direction is with less force than in the first direction, for abutment of the claw part on a driving member. Against the force of the first spring, the driving member is displaceable from abutment, into all gearshift positions following in the second direction. Gears preselected with stationary hub are engaged upon resumption of gear action.
