Abstract
A first and a second center washer are interposed between a pair of sun gears received within a housing. A first engagement portion comprising a pair of planetary gears, etc. is disposed on an internal side of the housing. Second engagement portions such as projections, etc. to be engaged with the first engagement portion through a space for play are formed on the two center washers, respectively. One surface of the first center washer is in contact with one surface of the second center washer. The other surface of the first center washer is in contact with an end face of one of the pair of sun gears, whereas the other surface of the second center washer is in contact with an end face of the other sun gear.
Claims5
A differential comprising:
- (a) a housing rotationally driven about a rotational axis, a first engagement portion being formed on an internal side of said housing;
- (b) a pair of sun gears rotatably received within said housing in a manner coaxial with said rotational axis;
- (c) at least one pair of planetary gears rotatably disposed within said housing, said planetary gears being in engagement not only with said pair of sun gears but also with each other;
- and
- (d) a first and a second center washer disposed between said pair of sun gears, one surface of said first center washer being in contact with one surface of said second center washer, the other surface of said first center washer being in contact with an end face of one of said pair of sun gears and the other surface of said second center washer being in contact with an end face of the other sun gear, said first and second center washers each having a basal portion and a second engagement portion formed at a peripheral edge of said basal portion, said second engagement portion being in engagement with said first engagement portion through a space for play;
- wherein said second engagement portions of said first and second center washers are axially aligned with each other, the first-mentioned mutually contacting surfaces of said first and second center washers being chamfered at circumferentially opposite side edges thereof.
A differential comprising:
- (a) a housing rotationally driven about a rotational axis, a first engagement portion being formed on an internal side of said housing;
- (b) a pair of sun gears rotatably received within said housing in a manner coaxial with said rotational axis;
- (c) at least one pair of planetary gears rotatably disposed within said housing, said planetary gears being in engagement not only with said pair of sun gears but also with each other;
- and
- (d) a first and a second center washer disposed between said pair of sun gears, one surface of said first center washer being in contact with one surface of said second center washer, the other surface of said first center washer being in contact with an end face of one of said pair of sun gears and the other surface of said second center washer being in contact with an end face of the other sun gear, said first and second center washers each having a basal portion and a second engagement portion formed at a peripheral edge of said basal portion, said second engagement portion being in engagement with said first engagement portion through a space for play;
- wherein a plurality of said first engagement portions are spacedly arranged in a circumferential direction of said housing, and said second engagement portion of said first center washer is circumferentially spaced away from said second engagement portion of said second center washer so that said second engagement portion of said first center washer and said second engagement portion of said second center washer are engaged with mutually different first engagement portions.
