Continuously variable transmission and control
This patent describes continuously variable drive mechanism and torque loading mechanism comprising; a variable diameter V-groove pulley having at least one movable sheave; a second V-groove pulley; a flexible torque transmitting torque between the V-groove pulleys; a first gear member mounted on the variable diameter V-groove pulley for rotation; first rotary support means for rotatably supporting the first gear member and the variable diameter V-groove pulley; a second gear member disposed in torque transmitting relation with the first gear member; stationary rotary support means for rotatably supporting the second gear member; link means connecting the first rotary support means and the stationary rotary support means for permitting the first rotary support means to pivot about the stationary rotary support means in response to the torque transmitted in the flexible torque transmitting means to establish the squeeze force in the flexible torque transmitting means and to control the center distance between the pulley. This forces transmitting means operatively connected with the link means to impose a force which establishes the minimum torque transmitting requirement for the flexible torque transmitting means prior to pivoting of the first rotary support about the stationary rotary support.
