Document Type and Number:
WIPO Patent Application WO/2017/146112
Kind Code:
A1
Abstract:
This electronically controlled V-belt continuously variable transmission is provided with: a first shift mechanism (75a), in which a centrifugal weight (93) is interposed between a weight supporting plate (92) and a cam member (87), wherein the first shift mechanism (75a) drives a centrifugal weight (93) by a centrifugal force accompanying the rotation of a drive shaft (32), and moves a movable sheave (74) in the axial direction; and an engagement member (102) that is disposed between the cam member (87) and the weight supporting plate (92) and, in connection with a movable sheave boss (74a), supports the weight supporting plate (92) on the movable sheave boss (74a). The engagement member (102) is provided with a press-fitting part (104), into which an oil seal member (105) is press-fitted around the drive shaft (32). As a result, the size of the electronically controlled V-belt continuously variable transmission can be reduced as much as possible.
