Abstract
A hydraulic clutch for preventing a drag of a clutch at the time of disengaging the clutch by decreasing an oil supply quantity between a plurality of clutch plates and a plurality of clutch discs thus decreasing a change hitting sound at the time of shifting. A hydraulic clutch is configured such that the superposition between an oil supply hole formed in a clutch pressure plate and an oil supply hole formed in a clutch center becomes maximum when the clutch is engaged.

A hydraulic clutch in which a plurality of clutch discs and a plurality of clutch plates are provided between a clutch outer and a clutch center, and the engagement and disengagement of the clutch are performed by pushing the plurality of clutch discs and the plurality of clutch plates by a clutch pressure plate, comprising:
- an oil supply hole formed in a portion of the clutch pressure plate and a portion of a guide portion of the clutch center which overlap with each other respectively, and
- the superposition between the oil supply hole formed in the clutch pressure plate and the oil supply hole formed in the clutch center becomes maximum when the clutch is engaged.
A hydraulic clutch comprising:
- a plurality of clutch discs;
- a plurality of clutch plates;
- a clutch outer and a clutch center, said plurality of clutch discs and said plurality of clutch plates being operatively mounted between said clutch outer and said clutch center, said clutch center including a guide portion, said clutch pressure plate and said guide portion overlapping relative to each other;
- a clutch pressure plate, said plurality of clutch discs and said plurality of clutch plates being brought into engagement and disengagement by pushing the plurality of clutch discs and the plurality of clutch plates by said clutch pressure plate;
- and
- an oil supply hole formed in a portion of the clutch pressure plate and a portion of said guide portion of the clutch center which overlap with each other respectively;
- wherein when said hydraulic clutch is engaged, the superposition between the oil supply hole formed in the clutch pressure plate and the oil supply hole formed in the guide portion of the clutch center becomes a maximum.
