Abstract
A differential mechanism has a differential casing for receiving drive power from an engine and a pair of output members for distributing the received drive power to road wheel ends. A pair of drive power control mechanisms each respectively comprise a combination of a speed change mechanism and a friction clutch for a serial connection between the differential casing and either output member or between the output members and an actuator for actuating the friction clutch to be let in. A controller controls a pair of the actuators to have a pair of the friction clutches periodically let in and let out in an alternating manner with a relatively short period.
Claims8
A differential apparatus comprising:
- a differential mechanism having:
- a differential casing for receiving drive power from an engine of a vehicle;
- and
- a pair of output members for distributing the received drive power to a pair of left and right axles of the vehicle;
- a pair of drive power control mechanisms each respectively comprising:
- a combination of a speed change mechanism and a friction clutch for a serial connection between the differential casing and either output member;
- and
- an actuator for actuating the friction clutch to be engaged;
- and
- a controller for controlling a pair of the actuators to have a pair of the friction clutches periodically engaged and disengaged in an alternating manner with a relatively short period.
