  • Patent number: 10371235
    Abstract: A family of transmission gearing arrangements produces nine forward and one reverse speed ratio by selective engagement of various combinations of three clutches or brakes. Each transmission gearing arrangement includes a front shiftable gearing arrangement configured to establish a variety of speed ratios between an intermediate shaft and an input shaft. These speed ratios include a reverse speed ratio, a zero speed ratio, two underdrive ratios, and a direct ratio. Each transmission also includes a rear shiftable gearing arrangement configured to selectively establish particular speed relationships. Engagement of a clutch in the rear shiftable gearing arrangement establishes an underdrive ratio between the output shaft and the intermediate shaft. Engagement of another clutch in the rear shiftable gearing arrangement constrains the speed of the input shaft to be a weighted average between the speed of the intermediate shaft and the output shaft.

  • Patent number: 10344837
    Abstract: Disclosed is a vehicle transmission with multiple gear stages, the transmission being capable of improving fuel economy and the performance of a vehicle. The vehicle transmission includes four planetary gear sets and six friction members. A shifting operation is performed such that rotary elements of the planetary gear sets are selectively connected and disconnected by the friction members so that the speed and direction of rotation of each gear are changed. Through this shifting operation, a vehicle can drive with one of ten or more forward speed gear ratios and one or more reverse speed gear ratios.

  • 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.
