Patent ID: 10767745

Abstract:
A pulley for a CVT has a fixed sheave, a movable sheave, a spider, a biasing member biasing the movable sheave axially away from the fixed sheave, at least one centrifugal actuator and at least one roller assembly. The at least one centrifugal actuator has an arm pivotally connected to one of the movable sheave and the spider. The arm has a thrust portion pushing against a track portion of a roller of the at least one roller assembly upon rotation of the CVT, the roller being rotationally connected to another one of the movable sheave and the spider. The roller receives the thrust portion of the arm on the track portion thereof such that the thrust portion of the arm remains in contact with the track portion of the roller. The arm and the roller thereby transfer axial and rotational forces between the spider and the movable sheave.
