Locking differential for four wheel drive - has three-position servo for freewheel and normal and locked drive

摘要

The locking differential is mounted between the half shafts (3a, 3b) of the non driven axle when the transmission is in two wheel drive. The halfshafts have clutches (33-31, 32-34) which disconnect the drive in two wheel mode and an additional clutch (35) which locks the differential effect. A single servo (4) drives all the clutch operation. The servo operates two claws (42, 43) which move the clutch parts. A first position covers the open clutch mode. A second position engages the clutches for normal travel while a third position locks the differential. The three positions are sequential. USE/ADVANTAGE - Compact differential action, quiet running for two wheel drive.
