    摘要: A powertrain has an engine, multi-range transmission and a final drive gearing. The transmission includes an input planetary gear set, the carrier of which is driven by the engine, for providing a power split between the sun gear and the ring gear. The sun gear and ring gear both are connected with respective transfer gear members. The gear members are connected to respective members of a continuously variable transmission unit (CVU) and to selectively engageable clutch mechanisms. The clutch mechanisms provide selective drive connections with an output transfer gear mechanism that is drivingly connected with the final drive gearing. The CVU is controlled to establish a variable drive ratio between the transfer gear members connected with the sun gear and the ring gear. Range changes in the powertrain occur at synchronous points of operation in the CVU in a manner to provide three forward ranges and a reverse range.

    摘要: A powertrain has an engine, a multi-range continuously variable transmission (CVT) and a final drive mechanism. The CVT has a continuously variable unit (CVU) and a planetary gear set. A plurality of friction devices that are selectively connectable to establish three forward ranges and one reverse range wherein the CVU is effective to provide infinitely variable ratios between the engine and the final drive mechanism. One friction device is engaged during a geared neutral condition, a first forward range and a reverse range. The neutral condition is established by setting the CVU at a predetermined ratio. The reverse range is operated by changing the CVU ratio toward a maximum underdrive ratio from the neutral condition and the first forward range is operated by changing the CVU ratio toward a maximum overdrive ratio. The second and third forward ranges are established by synchronously interchanging friction devices.

    摘要: A vehicular transmission embodying the concepts of the present invention permits facile construction by virtue of a modular construction. Such a transmission has an open ended central housing module (12). The annular stator (26,32) of one motor/generator (24,30) is supported interiorly of the annular central housing module (12), in such a manner as to circumscribe the longitudinal axis of the annular central housing module. A rotor is operatively positioned interiorly of the stator. The modular transmission incorporates a modular input closure subassembly (20) and/or a modular output closure modular subassembly (22). A closure subassembly has an end cap and a retaining shroud demountably attached to the end cap, and the closure subassembly is demountably secured to an open end of the central housing module. An input shaft member (66) is coaxially and rotatably supported by the input closure subassembly (20), if employed, and an output shaft member (158) is coaxially and rotatably supported by the output closure subassembly (22), if employed. One or more planetary gear subsets is coaxially supported in selected closure subassemblies to circumscribe the shaft member associated with the corresponding closure subassembly. A torque transfer device may be provided to selectively connect the planetary gear subsets and motor/generators to selected shaft members and selected shaft members to each other.
