ABSTRACT:
An independently suspended steering wheel has a hub lock for connecting and disconnecting the steering wheel to a variable length drive axle which includes a universal joint at each end. One hub lock part is connected to a wheel stub shaft journalled in the wheel hub. The other part of the hub lock is connected to a skirt portion of one universal joint which slides in a counterbore of the wheel hub. A spring plunger in the other universal joint normally biases the drive axle to an extended position where the hub lock is disengaged. The hub lock is engaged by a fluid motor incorporated in the wheel hub or an external selector which retracts the drive axle. A pneumatically controlled hydraulic pressure system operates the fluid motor.
