摘要： 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.
