Title:
LOCKING DIFFERENTIAL
Document Type and Number:
WIPO Patent Application WO/2011/092535
Kind Code:
A3
Abstract:
A locking differential mechanism (12) for supplying torque from a driveshaft to a pair of aligned output shafts (26, 28) including a pair of side gears (34, 36), a central driver (52), and a pair of clutch members (62, 64) operatively coupled for rotation with the corresponding one of the pair of side gears (34, 36). A cam assembly (78) includes a pair of cam members (80, 82). Each of the pair of cam members (80, 82) includes a plurality of camming teeth (88, 90) extending toward the corresponding teeth on the opposed cam member. Each of the cam members (80, 82) is movable from a first position where the cam teeth (88, 90) are disposed in meshing relationship with respect to each other when the pair of side gears (34, 36), are rotating at substantially the same speed and a second position spaced axially from the first position along the associated side gear (34, 36) so as to move an associated clutch member (62, 64) from its first position to its second position out of driven relationship with the central driver (52) in response to a difference in rotational speed of the associated pair of side gears (34, 36).
