ABSTRACT:
A nonshifting transmission, which may be used in combination with a torque converter, centrifugal clutch, or the like, and a torque converter especially adapted for use with the transmission. The transmission includes first and second input shafts, the second input shaft surrounding and concentric with the first input shaft, and an output shaft coaxial with the first input shaft. A planetary gear arrangement is connected solely to the first and second input shafts and the output shaft; no interconnection with any component stationary relative to the shafts being provided, resulting in a "differential" mechanism. A powered shaft is operatively connected to the first input shaft. First and second relatively movable shaft interconnecting members, such as a pump assembly and turbine assembly of a torque converter, are provided. The powered shaft may be integral with the first input shaft, and the torque converter may comprise turbine blades disposed radially outwardly of the pump impeller blades, and a reactor assembly disposed coaxially with the impeller and turbine blades and at the same radial position as the radial most extent of both. Utilizing the invention, turbine speed can substantially equal impeller speed.
