Topology of Open Differentials
An open differential consists of six general parts:
■Two pinion gears
■Two side gears
■A ring gear
■A differential housing
A revolute joint attaches each gear part, except for the ring gear, to the differential housing. A fixed joint attaches the ring gear to the differential housing.
The differential has three couplers (gear functions). The couplers act between:
■Rear pinion gear - right side gear
■Right side gear - front pinion gear
■Front pinion gear - left side gear
The gear radius specifies the gear ratios.
