Title:
CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP2015178878
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a one-way clutch and a continuously variable transmission, which are capable of reducing an initial speed at which rollers project at a time of disengagement and preventing NVH degradation due to collision of the rollers against a stopper portion at a high speed.SOLUTION: A one-way clutch includes: an outer member 22; an inner member 23; a plurality of rollers 25 disposed between the outer member 22 and the inner member 23; a pair of bearings 34 proximate to axially both end surfaces of each roller and pivotally supporting the outer member 22 and the inner member 23 so that the members are relatively rotatable; a plurality of elastic members 24 abutting on the respective rollers; and a plurality of holding members 33 holding the elastic members 24. Each roller rolls in a circumferential direction within a space S surrounded by the outer member 22, the inner member 23, each holding member 33, and the paired bearings 34, the space S being filled with lubricant. Each holding member 33 includes a first valve 51 communicating with an adjacent space only in a first direction w1 in which the roller rolls for engagement, and a second valve 52 communicating with an adjacent space only in a second direction w2, and the flow volume of the first valve 51 is larger than that of the second valve 52.
