摘要： The present invention relates to a continuously variable transmission constructed in such a way that it can speed-change the power inputted to an input shaft according to the load applied to an output shaft and transmit the power to the output shaft even though all the gears remain engaged, and in addition reverse operation can also be effectuated in a simple way. Reviewing the construction thereof, it is mainly composed of a speed change system, which receives power generated by an engine, changes speed and transmits it to the output shaft, a speed change controlling system which automatically adjusts the rotational ratio to correspond to the condition of the load on the output shaft, and a reverse rotation system. The present invention, comprises two (compund) gear sets in which each same element is removed from two planet gear sets; and a reverse rotation system, and the power inputted through an input element selected from the two gear sets is changed into the required speed and transmitted to the output shaft. Reviewing the operational characteristics, the present invention is constructed in such a way that the decelerated rotation smaller than the input rotation is transmitted to the impeller by utilizing an direct clutch. Therefore, it is a characteristic of the present invention that the rotational force transmitted to the impeller is alway larger than the input torque. In view of the effects, the present invention can obtain a large propulsion force, preferable performance, smooth and quiet operation, and can speed-change steplessly at the time of reverse operation.
