Abstract
A differential gear assembly for an automobile includes an annular ring gear, a differential case, a pair of side gears substantially axially aligned and spaced apart from each other and adapted to be supported by the differential case and to engage an axle shaft of the automobile, and a pair of differential pinion gears substantially axially aligned and spaced apart from each other, and adapted to engage the side gears. A differential pin is secured to and extends diametrically across the ring gear and is adapted to support the differential pinion gears in engagement with the side gears and to allow rotational movement of the differential pinion gears about the differential pin.
Claims5
A differential gear assembly for an automobile comprising:
- an annular ring gear having an internal surface and an external surface;
- a differential case;
- a pair of side gears substantially axially aligned and spaced apart from each other, each of said side gears adapted to be supported by said differential case and to engage an axle shaft of the automobile;
- a pair of differential pinion gears substantially axially aligned and spaced apart from each other, each of said differential pinion gears being adapted to engage said side gears;
- and
- a differential pin attached to and extending diametrically across said ring gear, wherein said differential pin is rotatable about a longitudinal axis of said differential pin but is otherwise immobile relative to said ring gear, said differential pin including a first end, a second end, and slots formed within the side of said differential pin adjacent to said first end and said second end, said differential gear assembly further including a pair of clips which are adapted to engage said slots at said first and second ends of said differential pin to rotatably support said differential pinion gears in engagement with said side gears.
