    摘要： A primary clutch assembly for a continuously variable transmission is provided. The primary clutch assembly includes a fixed sheave and a movable sheave centered on a post for joint rotation therewith. A rotational unit disposed on the post generates centrifugal forces during rotation of the post that are translated axially to urge the movable sheave along the post towards the fixed sheave. The primary clutch utilizes an actuator assembly that is configured to establish a locked condition that prevents axial movement of the movable sheave as the rotational unit builds-up centrifugal force and an unlocked condition to allow sudden axial movement of the movable sheave towards the fixed sheave. The actuator assembly includes a bearing unit that extends through a hole in the post to contact the movable sheave in the locked condition and is housed within the hole and spaced from the movable sheave in the unlocked condition.

    摘要： [Problems to be Solved] To provide a power transmission chain which not only can prevent the occurrence of an edge contact phenomenon in which the edge portion of a pin end face is contacted with a pulley, but also can enhance the power transmission efficiency.[Means for Solution] According the power transmission chain, in the end face 17 of a first pin 3 for connecting links to each other, there is provided a contact area 21. The contact area 21 is contacted with the pulley to transmit power. When viewed from the width direction of the chain, the contact area 21 has an egg-like shape which is relatively long in a longitudinal direction J and relatively short in a transverse direction K. The contact area 21 intersects with a first plane H1 to form a first intersection line L1. The contact area 21 intersects with a second plane H2 to form a second intersection line L2. The first intersection line L1 has a plurality of radiuses of curvature R1, R2.

    摘要： A continuously variable transmission has dual driving connections extending between a first shaft and a second shaft. The driving connections generally include a drive pulley, a driven pulley and a belt. The pulleys each comprise a fixed portion and an axially moveable portion. Movement between the two portions changes an effective diameter of the pulley. The moveable portions of the drive pulley are positioned next to one another on the first shaft and the moveable portions are interposed between the fixed portions of the drive pulleys. The fixed portions of the driven pulleys, on the other hand, are interposed between the moveable portions. The driven pulleys are free to rotate relative to the second shaft. A differential is positioned between the fixed portions of the driven pulleys, connects the two fixed portions and transfers the torque from the driven pulleys to the second shaft.
