Abstract:
A one mode, front wheel drive continuously variable transmission includes a transmission input member interconnected to an engine of the motor vehicle, a transmission output member, a continuously variable unit having a first pulley pair, a second pulley pair, and a chain wrapped around the first pulley pair and the second pulley pair. A planetary gear set includes a first member, a second member, and a third member. The first member is connected to the first pulley pair and the third member is connected to the transmission input member. A clutch is selectively engageable to connect the first member of the planetary gear set with the transmission input member. A band brake selectively engageable to connect the second member with a stationary member. The transmission output member is interconnected to a differential supported by sets of ball bearings.
