Continuously variable transmission apparatus and air conditioning system having the same

A continuously variable transmission apparatus comprising:

• an input shaft that is adapted to be rotated by a drive force received from a drive source;
• an output shaft that is placed coaxially with the input shaft and outputs a drive force in response to rotation of the input shaft;
• a continuously variable transmission mechanism that is placed between the input shaft and the output shaft;
• a differential gear mechanism that is placed between the continuously variable transmission mechanism and the output shaft;
• and
• a bypass shaft that is placed coaxially with the input shaft and the output shaft, wherein:
• the continuously variable transmission mechanism is adapted to conduct rotation of the input shaft to the differential gear mechanism after changing a speed of the rotation;
• the bypass shaft is adapted to conduct the rotation of the input shaft to the differential gear mechanism while bypassing the continuously variable transmission mechanism;
• the differential gear mechanism is adapted to conduct the rotation from the continuously variable transmission mechanism and the bypass shaft to the output shaft;
• the continuously variable transmission mechanism includes:
• an input-side swing arm that is adapted to be swung about a swing axis thereof by the force transmitted from the input shaft;
• a support member, by which the input-side swing arm is swingably supported;
• a rotation-to-swing converting mechanism that converts a single directional rotational motion of the input shaft into a swing motion of the input-side swing arm;
• an output-side swing arm that is adapted to be swung about a swing axis thereof when the output-side swing arm is urged by a corresponding part of the input-side swing arm;
• a swing-to-rotation converting mechanism that converts a swing motion of the output-side swing arm into a single directional rotational motion;
• and
• an adjusting mechanism that adjusts an amount of swing of the output-side swing arm by changing a location of a point of action of the input-side swing arm relative to the output-side swing arm in a radial direction of the swing axis of the input-side swing arm;
• and
• the swing-to-rotation converting mechanism conducts the single directional rotational motion to the differential gear mechanism.
