Title:
BELT-TYPE STEPLESS TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2018/051741
Kind Code:
A1
Abstract:
This belt-type stepless transmission is configured so that, in order to axially shift the movable sheave of the belt-type stepless transmission, a first shift mechanism which has an actuator and a second shift mechanism which has a centrifugal mechanism are used in combination. The ramp plate (41) of the centrifugal mechanism (40) integrally has: a plate boss (41b) surrounding the boss section (22b) of the movable sheave (22); and a plate body section (41a) protruding radially outward from the plate boss (41b) and holding a centrifugal weight (43) between the plate body section (41a) and the cam member (42) of the centrifugal mechanism (40). A peripheral surface of the boss section (22b) of the movable sheave (22) and a peripheral surface of the plate boss (41b), the peripheral surfaces facing each other, are directly joined (70). As a result of this configuration, the boss section of the movable sheave and the ramp plate of the centrifugal mechanism can be directly connected without nut to prevent the axial enlargement of the movable sheave and the radial enlargement of the centrifugal mechanism, and the stepless transmission can be made axially and radially compact.
