Family of multi-speed power transmission mechanisms having three planetary gearsets and five torque-transmitting mechanisms

摘要

A family of power transmissions which are utilized in a powertrain include three planetary gearsets and five torque-transmitting mechanisms. The torque-transmitting mechanisms are engaged in combinations of three to provide a reverse drive ratio and six forward speed ratios. The torque-transmitting mechanisms will include at least four rotating type torque-transmitting mechanisms and, in some instances, one stationary type torque-transmitting mechanism. The planetary gearsets are of either the single pinion type or of the double pinion type of planetary gearsets.
