Abstract
A regenerative transmission that utilizes three prime mover input modes. The transmission has at least one planetary gear set, and each planetary gear set has an inner gear member, an outer gear member and a plurality of planet gear members meshingly engaging the inner and outer gear members. The planet gear members are operatively mounted on a carrier in each planetary gear set. The outer gear member in each planetary gear set is grounded, and the inner gear member in each planetary gear set is connected to a respective motor/generator. An output shaft is provided and means are provided selectively to connect the carrier in each planetary gear set to the output shaft. A plurality of torque transfer devices selectively connect the prime mover input modes to the output shaft.
