摘要： A powertrain includes a continuously variable traction drive unit, a two-mode planetary gear set, and transfer gearing between the continuously variable unit (CVU) and the planetary gear unit. The planetary gear unit is essentially a four-node linkage mechanism having two members of each gear set interconnected. One member of one of the gear sets is connected to the CVU through a low range clutch and one of the interconnected members is connectable with the CVU through a high range clutch and another member is continuously connected with a prime mover, such as an engine. The planetary gear unit is controlled to provide a low mode that is controllable through the ratio of the CVU to establish a reverse range, a neutral condition, and a forward range. The planetary gear unit is also controllable to provide a high mode wherein the output the CVU and a mechanical path are combined at one gear set to provide a split drive, wherein a portion of the power is transmitted by the CVU and a portion of the power is transmitted by the more efficient mechanical path.

摘要： A planetary gearing arrangement has a compound planetary gear set and a simple planetary gear set. The planetary gear sets are continuously interconnected at the sun gear members and are interconnectable through the selective engagement of two proportioning clutches which change the interaction of the gear sets. A single member, a ring gear, is continuously connected to an output shaft. The arrangement also includes two input clutches and two brakes which in combination with the proportioning clutches permit the establishment of five forward ratios and one reverse ratio. Two of the forward ratios are underdrives and two of the ratios are overdrives. All of the forward ratio interchanges, the neutral to forward ratio change and the neutral to reverse ratio change are of the single transition type.
