Document Type and Number:
Japanese Patent JP6643946
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic clutch device capable of being clutched-in with a strong operating force by a disk spring while avoiding a large-sized clutch drum.SOLUTION: A multiple-disk friction clutch part 42 is pressed into a clutched state with an overall elastic restoring force by an overlapping disk spring 32. The multiple-disk friction clutch part 42 is operated in a disengaged state by releasing the pressing operation of the disk spring 32 using a hydraulic piston 31 to which hydraulic pressure is supplied. The disk spring 32 and the hydraulic piston 31 are located on the opposite side of the position where the multiple-disk friction clutch part 42 is located with respect to a rim part 40c connecting between a drum part 40b of a clutch drum 40 and a boss part 40a. The hydraulic clutch device comprises an operation force transmission member 48 in which a rim part 40c is slidably inserted in an axial direction for transmitting the elastic restoring force of the disk spring 32 to the multiple-disk friction clutch part 42.SELECTED DRAWING: Figure 3
