BELT-TYPE CONTINUOUSLY VARIABLE TRANSMISSION

WIPO Patent Application WO/2018/168575

A1

A belt-type continuously variable transmission equipped with: a transmission member (89) arranged so as to be incapable of displacement in the axial direction relative to a fixed sheave (71), and having a cam surface (89a) that approaches the fixed sheave as the distance from the rotational axis (Xis) of a crankshaft (32) increases; a centrifugal weight (76) that is sandwiched between the transmission member and a movable sheave (72) and that moves along the cam surface in the centrifugal direction in response to increased centrifugal force, thereby driving the movable sheave in the axial direction; an amplification member (93) mechanically coupled to the movable sheave and having multiple restricting bodies (92) that move along a prescribed trajectory with an amount of displacement that amplifies the amount of axial displacement of the movable sheave; and a lock member (94) that is linearly displaced between a first position in which the lock member contacts any one of the restricting bodies of the amplification member and restricts the movement of the restricting body, and a second position in which the lock member moves away from the restricting body and allows movement of the restricting body. Thus, it is possible to provide a belt-type continuously variable transmission with which the transmission gear ratio can be fixed with an inexpensive structure.
