A continually variable transmission includes an input shaft, an output shaft and a first drive mechanism having a first input on a first axis and a first output on a second axis. The first drive mechanism produces a fixed ratio of the speed of the first input to the speed of the first output. The first input drives the first output without a member on an intervening axis. A second drive mechanism is arranged in parallel with the first drive mechanism, having a second input and second output, for producing a stepless, continually variable range of ratios of the speed of the second input to the speed of the second output. A mode clutch alternately driveably connects and releases either the members of a first group consisting of the first input and second input or the members of a second group consisting of the first output and second output. A mechanism is provided for driving the output shaft in the same direction as the input shaft and for reversing the direction of rotation of the output shaft relative to the direction of rotation of the input shaft.

Compact dual mode continually variable transmission

A continually variable transmission includes a torque converter for producing a hydrokinetic connection between a power source and input shaft, a low gear drive mechanism, a belt drive mechanism arranged in parallel with the low gear mechanism between the input shaft and an intermediate shaft, a forward-reverse gearset, a forward clutch, a reverse brake for controlling operation of the gearset in the direction of its output, and a mode clutch for alternately selecting the torque path between the input shaft and intermediate shaft.

Dual mode continually variable transmission

A pulley shaft and stationary pulley assembly for a belt drive mechanism of a continuously variable transmission includes an inner surface of the pulley having metal-cutting serrations, a blocking shoulder, and a surface for engaging a pilot guide surface formed on the shaft. The shaft, formed of softer material than the hardened pulley, includes a shoulder adapted to have serrations formed in it during the assembly process, a hardened pilot guide, and a blocking shoulder adapted to contact the blocking shoulder of the pulley.
