Abstract
The instant invention pertains to a hub clutch assembly mounted between an axle and a hub of a four-wheel drive vehicle for changeover between two-wheel drive and four-wheel drive using fluid pressure. An inner ring is moved, by supplying or sucking air to or from one of the chambers airtightly sealed by a diaphragm, into or out of engagement with an outer ring for changeover between two-wheel drive and four-wheel drive modes. The diaphragm has a hardness of 50-70 Hw to prevent a reduction in the thrust of fluid pressure for changeover. The diaphragm also has a convex configuration extending towards the outer ring.
Claims20
A hub clutch assembly, comprising:
- a driving member;
- a driven member operably associated with said driving member;
- and
- a diaphragm, having a hardness of 50-70 Hw, operably associated with said driving member and said driven member, wherein said diaphragm is movable under fluid pressure between a first position in which said driving member is disengaged from said driven member and a second position in which said driving member is engaged with said driven member.
A hub clutch assembly, comprising:
- a driving member;
- a driven member;
- and
- a diaphragm operably associated with said driving member and said driven member, wherein said diaphragm is movable under fluid pressure between a first position in which said driving member is disengaged from said driven member and a second position in which said driving member is engaged with said driven member, and wherein when in said first position said diaphragm defines a convexity directed along the direction of movement of said diaphragm from said first position to said second position.
