Abstract
Abstract A WHEEL HUB CLUTCHING MECHANISM HAS A DIAL WHICH, WHEN TURNED TO A "FREE" POSITION, MOVES AN ACTUATOR NUT TO PLACE SPRINGS UNDER TENSION TO MOVE A CLUTCH OUT OF MESH WITH A SHAFT DRIVEN PINION. WHEN THE DIAL IS MOVED TO A "LOCK" POSITION, IT MOVES THE ACTUATOR NUT TO PLACE THE SPRINGS UNDER COMPRESSION TO MOVE THE CLUTCH INTO MESH WITH THE PINION. THE DIAL HAS A THREADED PORTION WHICH DRIVES THE NUT ALONG A SPLINING ROD WHICH INSURES CORRECT INDEXING OF THE NUT RELATIVE TO THE DIAL.
