Zusammenfassung:	A primary clutch of a continuously variable transmission with a launch mechanism is provided. The primary clutch includes a central post, a fixed sheave assembly, a movable sheave assembly and a locking mechanism. The central post is configured to receive rotational torque from a motor. The fixed sheave assembly is statically mounted on the central post. The movable sheave assembly is mounted on the central post. The movable sheave assembly includes a movable sheave system that is configured to move axially on the central post towards the fixed sheave assembly as RPM of the primary clutch increase. The locking mechanism is configured and arranged to selectively prevent movement of the movable sheave system independent of the RPM of the primary clutch. L'invention concerne un embrayage primaire d'une transmission à variation continue avec un mécanisme de démarrage. L'embrayage primaire comprend un montant central, un ensemble poulie fixe, un ensemble poulie mobile et un mécanisme de verrouillage. Le montant central est conçu pour recevoir un couple de rotation provenant d'un moteur. L'ensemble poulie fixe est monté de manière statique sur le montant central. L'ensemble poulie mobile est monté sur le montant central. L'ensemble poulie mobile comprend un système de poulie mobile qui est configuré pour se déplacer axialement sur le montant central vers l'ensemble poulie fixe en tant que régime de l'augmentation d'embrayage primaire. Le mécanisme de verrouillage est configuré et agencé pour empêcher sélectivement le mouvement du système de poulie mobile indépendamment du régime de l'embrayage primaire.
