A flyweight comprises a body. The body of the flyweight comprises a pivot, a cam surface, and a first coupler. The first coupler is configured to selectively couple at least one first weight to the body distal from the cam surface. A flyweight comprises a body having at least 20% of its mass positioned to contribute negative torque about a pivot related to an acceleration of a CVT clutch from an idling condition. A method of tuning a flyweight comprises attaching at least one first weight to a first coupler of a body of the flyweight distal from a cam surface of the body. A CVT clutch comprises at least one flyweight with a first coupler configured to selectively couple at least one first weight to a body of the flyweight distal from a cam surface.

A continuously variable transmission (CVT) is disclosed which is operable in a first direction to transfer power from a power source to ground engaging members of a vehicle, and in a second direction where the ground engaging members brake and/or drive the engine. The CVT has a braking assembly having a thrust member positioned over a drive clutch shaft and adjacent an outer sheave of the drive clutch. A flanged sleeve is operatively coupled to the drive clutch shaft and generally positioned intermediate the inner and outer sheaves of the drive clutch, with a portion of the flanged sleeve being adjacent the thrust member. The flanged sleeve is fixed relative to the drive clutch shaft when operating in the first direction and is cooperable with the thrust member to move the flanged member axially relative to the drive clutch shaft and towards the inner sheave when operating in the second direction.

A utility vehicle comprises a traveling driving power source which generates rotational driving power for driving a drive wheel; a continuously variable transmission including an input shaft to which the rotational driving power transmitted from the traveling driving power source is input, an output shaft which outputs the rotational driving power toward the drive wheel, a drive pulley provided at the input shaft, a driven pulley provided at the output shaft, and a belt wrapped around the drive pulley and the driven pulley; a clutch which is disposed in a driving power transmission path at a location that is between the belt and the drive wheel and is capable of disconnecting the driving power transmission path; and a clutch actuator which operates the clutch.

A drive clutch including a primary post, a fixed sheave, a movable sheave, an activation assembly is provided. The fixed sheave is statically coupled to the primary post. The movable sheave is slidably mounted on the primary post. The activation assembly is in operational communication with the movable sheave to move the movable sheave on the primary post away from and towards the fixed sheave based on a centrifugal force experienced by the drive clutch. The activation assembly includes a spider, at least one trunnion slidably mounted on a spider arm and a main activation biasing member. The at least one trunnion has opposable extending trunnion arms. A roller is rotationally mounted on each trunnion arm. Each roller is positioned to engage a ramp profile associated with a sheave post extending from the movable sheave. The main activation biasing member is positioned to assert a biasing force on the spider.

Disclosed is a washing machine including a transmission. The transmission includes: a variable driving side pulley unit arranged on a side of the output shaft; a variable driven side pulley unit arranged on a side of the input shaft; a driving belt capable of transferring the power between the variable driving side pulley unit and the variable driven side pulley unit; a rotating speed sensing part arranged in the driving side pulley unit and configured to change a pulley diameter with the increase of rotating speed; and a torque cam mechanism arranged between pulley hubs and that form a movable pulley and a fixed pulley of the driven side pulley unit and configured to control speed variation time when the pulley diameter varies in a reversing direction with the increase of the rotating speed via cam grooves and pins.

The present invention relates to a continuously variable transmission (1000, 8000) for a bicycle comprising: input means (1100, 2100, 3100), output means (1300, 2300, 3300, 4300, 300, 6300), and transmission means (1200) connecting the input means to the output means, wherein the output means comprise output controlling means (1340, 2340, 3340, 4340, 5340, 6340) controlling a gear ratio of the output means, wherein the continuously variable transmission is a V-belt type continuously variable trans mission.

A drive clutch including a primary post, a fixed sheave, a movable sheave, an activation assembly is provided. The fixed sheave is statically coupled to the primary post. The movable sheave is slidably mounted on the primary post.

Each roller is positioned to engage a ramp profile associated with a sheave post extending from the movable sheave. The main activation biasing member is positioned to assert a biasing force on the spider.

A slide roller is provided. A lower connecting surface of the roller is never in contact with a roller passage surface. By taking advantage of a normal distance between a corner sliding surface and a center point of the roller greater than a vertical distance between an upper sliding surface of the roller and the center point, a pulley disc assembly can be started lightly, the acceleration in the middle stage of the slide stroke is increased, and speed transmission in the rear stage of the slide stroke is increased.
