Title:
POWER TRANSMISSION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2015098924
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve engaging response of a one-way clutch by allowing auto-rotation of a roller during engagement, and restraining auto-rotation of the roller during disengagement.SOLUTION: A protrusion 38b for applying a small friction force when the roller 25 is auto-rotated in a first direction c that is an engaging direction, and applying a small friction force when the roller 25 is auto-rotated in a second direction c' that is a disengaging direction is provided at a pressing part 38a of an axial spring 38 contacting a first end face 25a of the roller 25. Therefore, while a one-way clutch 21 is engaged, the auto-rotation of the roller 25 in the first direction c can be assisted to realize quick engagement. While the one-way clutch 21 is disengaged, the auto-rotation of the roller 25 in the second direction c' is restrained to prevent excessive compression of an engaging spring 38. Therefore, the roller 25 can be quickly returned to a datum point, so as to further improve engaging response of the one-way clutch 25.
