COMBINED TORQUE CONVERTER AND TRANSMISSION SYSTEM AND METHOD THEREFOR

摘要

The present invention relates to a combined torque converter system for a vehicle, the system including a planetary transmission in a rotating housing and a transmission in a stationary housing. The transmission comprises a drive shaft which is arranged as to be connected to a torque delivered by a motor. The transmission comprises a drive shaft connected to an output shaft of the planetary transmission. According to certain embodiments, the at least one transmission is a planetary transmission such as a Ravigneaux gearset, a Simpson gearset, a plurality of simple transmissions or a Lepelletier six speed arrangement. The transmission includes a plurality of transmission ratios, the planetary transmission being configured in such a way that it increases the plurality of transmission ratios by adding at least a first transmission ratio to the plurality of transmission ratios. According to certain embodiments, the planetary transmission is configured in such a manner that it doubles the number of transmission ratios.
