  • Patent number: 10316941
    Abstract: Disclosed is a transmission for a vehicle that can improve fuel efficiency by implementing multiple steps of shifting and improve vehicle driving comfort by using operating points in a low RPM range of an engine. According to the transmission, since three single planetary gear sets and one compound planetary gear set are combined or five single planetary gear sets are compound and the rotary elements of the planetary gear sets and friction members are selectively connected and disconnected, their rotational speeds and directions are changed when shifting is performed. Therefore, a vehicle can be driven with the gear ratios of ten or more steps of forward shifting and one step of reverse shifting.
