Abstract:
A two mode continuously variable transmission (CVT) for a motor vehicle includes an optional speed change device connected to a pulley and a belt assembly or other continuously variable unit. The pulley and belt assembly is also connected to a gear box having a planetary gear assembly. The gear box has two brakes and a clutch. The gear set arrangement is connected to a final drive unit. Selective engagement of the clutch and brakes provides two modes of operation to the CVT.
