Abstract
A driving force distribution device includes a first output rotational member and a second output rotational member, an input rotational member, a first multiple disc clutch, a second multiple disc clutch, a pressure receiving member, a first pressing mechanism and a second pressing mechanism. The pressure receiving member includes an annular base portion and a plurality of projecting pieces, the projecting pieces include a plurality of first projecting pieces and a plurality of second projecting pieces. The first projecting pieces each have a first pressure receiving surface, the second projecting pieces each have a second pressure receiving surface.
Claims7
A driving force distribution device comprising:
- a first output rotational member and a second output rotational member placed to rotate relative to each other on the same axis;
- an input rotational member placed to rotate relative to the first output rotational member and the second output rotational member on the same axis;
- a first multiple disc clutch placed between the input rotational member and the first output rotational member and including a plurality of clutch plates;
- a second multiple disc clutch placed between the input rotational member and the second output rotational member and including a plurality of clutch plates;
- a pressure receiving member placed between the first multiple disc clutch and the second multiple disc clutch;
- a first pressing mechanism configured to press the first multiple disc clutch toward the pressure receiving member;
- and
- a second pressing mechanism configured to press the second multiple disc clutch toward the pressure receiving member, wherein:
- the pressure receiving member includes an annular base portion fixed to the input rotational member, and a plurality of projecting pieces projecting radially from the base portion;
- the projecting pieces include a plurality of first projecting pieces and a plurality of second projecting pieces;
- the first projecting pieces each have a first pressure receiving surface configured to receive a pressing force of the first pressing mechanism via the first multiple disc clutch;
- the second projecting pieces each have a second pressure receiving surface configured to receive a pressing force of the second pressing mechanism via the second multiple disc clutch;
- a first back face as a back face of the first pressure receiving surface is at least partially placed closer to the first multiple disc clutch side than the second pressure receiving surface;
- and
- a second back face as a back face of the second pressure receiving surface is at least partially placed closer to the second multiple disc clutch side than the first pressure receiving surface.
