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.
