Continuously variable transmission apparatus and air conditioning system having the same

摘要

A continuously variable transmission apparatus includes an input shaft, an output shaft, a continuously variable transmission mechanism, a differential gear mechanism and a bypass shaft. The continuously variable transmission mechanism is placed between the input shaft and the output shaft and 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 placed coaxially with the input shaft and the output shaft and 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.

1. 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; a bypass shaft that is placed coaxially with the input shaft and the output shaft; and a first rotation limiting mechanism, which is adapted to limit a rotational direction of the bypass 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 differential gear mechanism is formed as a single pinion planetary gear mechanism; the first rotation limiting mechanism limits rotation of the bypass shaft in a first rotational direction, which is the same as a direction of the rotation conducted from the continuously variable transmission mechanism to the differential gear mechanism; and the first rotation limiting mechanism enables rotation of the bypass shaft in a second rotational direction, which is opposite from first rotational direction.
