Abstract
A differential gear assembly has a friction clutch for restricting differential action. The clutch is actuated by an actuator which moves in a linear direction. The actuator is driven remotely in one embodiment by means of a rotating element, and in another embodiment by means of a spring biased pivotal element.
Claims5
A locking differential gear assembly comprising;
- clutch means for restricting the differential action of said assembly;
- movable means movable in a linear direction to actuate said clutch means;
- rotatable pressing means for moving said movable means in said linear direction;
- drive means for rotating the pressing means;
- and converting means for converting the rotation of said pressing means into linear movement, said converting means including an element fixed in relation to said pressing means, with interengaged threaded portions on said pressing means and said element.
2 more elements
A locking differential gear assembly comprising:
- a housing including a detachable cover;
- clutch means contained within said housing for restricting the differential action of said gear assembly;
- first actuating means movable in a linear direction to actuate said clutch means;
- second actuating means pivotably carried on said cover and engageable with said first actuating means to move said first actuating means in said linear direction;
- spring means for biasing said second actuating means into engagement with said first actuating means;
- and means for adjusting the biasing force of said spring means from the exterior of said housing to obtain a predetermined differential restriction value.
