CLUTCH HUB

Japanese Patent JP2017161048

A

PROBLEM TO BE SOLVED: To solve a problem that there has been a possibility that a seizure accident occurs due to the lubrication shortage of a clutch plate which is placed in a longitudinal center part of a clutch hub of a wet multiplate clutch.SOLUTION: In a clutch hub 15 which comprises a cylinder part 20 to which a plurality of pieces of annular clutch plates 16 are spline-fit, and a plurality of penetration holes 20i, 20c and 20o for making an internal peripheral face and an external peripheral face of the cylinder part 20 communicate with each other, a part of a lubricant supplied to the internal peripheral face of the cylinder part 20 from one end side of the cylinder part 20 in a longitudinal direction is guided to the external peripheral face side of the cylinder part 20 through the penetration holes 20i, 20c and 20o, and a remaining lubricant flows out of the other end of the cylinder part 20. The clutch hub further comprises a plurality of weir parts 32 which are arranged while being shifted to a center of the cylinder part 20 in the longitudinal direction rather than the penetration hole 20o which is most approximate to the other end side of the cylinder part 20 in the longitudinal direction, and protruded to the inside of a radial direction from the internal peripheral face of the cylinder part 20. A clearance 32g for guiding the lubricant to the other end side of the cylinder part 20 in the longitudinal direction is defined between the weir parts 32 which adjoin each other in a peripheral direction.SELECTED DRAWING: Figure 2
