Drive clutch a CVT

A vehicle comprising:

• a motor to provide motor torque,
• a continuously variable transmission including drive clutch, driven clutch and a belt, the drive clutch in operational communication with the motor to receive the motor torque, the belt in operation communication with the drive clutch and the driven clutch to pass torque from the drive clutch to the driven clutch, the drive clutch including,
• a primary post configured to receive the motor torque from the motor,
• a fixed sheave statically coupled to the primary post;
• a movable sheave slidably mounted on the primary post, the movable sheave having a first side positioned to face the fixed sheave and a second side, at least one sheave post extending from the second side of the movable sheave;
• and
• an activation assembly in operational communication with 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 including,
• a spider with at least one spider arm, the spider generally locked to a rotation of the primary post,
• at least one trunnion slidably mounted on the at least one spider arm, the at least one trunnion having opposable extending trunnion arms,
• a roller rotationally mounted on each trunnion arm, each roller positioned to engage a ramp profile associated with a sheave post of the at least one sheave post of the movable sheave, and
• a main activation biasing member positioned to assert a biasing force on the spider;
• and
• a drive train in operational communicational with the driven clutch.
