Document Type and Number:
Japanese Patent JPS60113850
Kind Code:
A
Abstract:
A continuously variable transmission with wide ratio coverage has a variable ratio belt drive in series with a fixed ratio drive which is selectively connectible between the input and output shafts. A pair of selectively engageable clutches cooperate with the belt drive to provide two continuously variable speed ratio ranges. A transition clutch maintains power flow between the input and output shafts during shifting from one range to the other. The belt drive is controlled between the maximum and minimum drive ratios in each speed range. The belt ratio is held constant while the transition clutch is engaged.
