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.
