    摘要: An input-compound split electromechanical drive configuration includes a two-mode planetary gearset arrangement coupled to an internal combustion engine and first and second electric machines. The drive configuration includes a transverse output for driving a hybrid front wheel drive vehicle, and the electric machines are disposed on opposite axial ends of the planetary gearset arrangement. A first mode provides reverse, neutral and low forward ranges, and a second mode provides a high efficiency forward range. Shifting between the first and second modes occurs synchronously, and at a zero speed of the second machine, contributing to an exceptionally smooth shift, and the machines are independently operated in motoring or generating modes to control drivetrain power flows while satisfying the vehicle power requirements.

    摘要: A hydraulic closed loop control for positioning a transmission shift rail and synchronizer fork has recesses on the rail and ports in a valve body in which the rail is disposed. Fluid flow between the ports as permitted by the rail recesses controls the position of valves which in turn control the position of the rail. The valves control the position of the rail by routing pressurized fluid to one of two opposing sides of a piston fixed to the rail in response to the flow of fluid from the valve body ports. The pressurized fluid moves the rail to a desired position with the flow of pressurized fluid being interrupted when that position is reached.

    摘要: A power transmission has a housing comprised of an end support, a casing, an end cover, a converter housing, an input shaft, an output shaft and a pair of identically dimensional countershafts. A bushing and oil feed sleeve are positioned on each end of each countershaft for cooperating with the end support connecting the housing for alignment therebetween and with the casing for alignment therebetween. Each countershaft has a pair of ratio gears rotatably disposed thereon and meshing with respective output gears rotatable with the output shaft and a friction clutch is provided for each ratio gear. Four of the friction clutches which are disposed on the countershafts are identical in construction. A fifth clutch assembly, in line with the input shaft, can be shortened, if desired, by the elimination of one friction plate and one reaction plate. Each clutch has an apply piston which cooperates with respective lube passages formed in the shaft to control lubricant and cooling flow to each respective clutch during engagement. A reverse gear pair has one gear member connectible to one countershaft by a synchronizer clutch and one of the friction clutches and the other gear member drivingly connected with a ratio gear on the other countershaft. A park pawl secured to one of the reverse gear members is provided to obtain a park gear having a torque ratio greater than one with the output shaft thereby providing improved disengagement loading in the park system.

    摘要: Eight-speed transmissions are provided that include four planetary gear sets having seven torque-transmitting mechanisms and various fixed interconnections to provide eight forward speed ratios and at least one reverse speed ratio. The powertrain includes an engine and torque converter that is continuously connected to at least one of the planetary gear members and an output member that is continuously connected with another of the planetary gear members. The seven torque-transmitting mechanisms are operated in combinations of two. Reduced component speeds and improved ratios are achieved.

    摘要: A hybrid electromechanical transmission includes first, second and third planetary gear sets, an input member, an output member, and first and second motor generators. At least one of the gear members in the first planetary gear set is connected to the first motor/generator. At least one of the gear members in the third planetary gear set is connected to the second motor/generator. First and second interconnecting members continuously connect members of the first planetary gear set with members of the second planetary gear set. Five torque-transmitting mechanisms selectively interconnect members of the planetary gear sets with a stationary member or with other members of the planetary gear sets. One of the five torque-transmitting mechanisms is operative to selectively disconnect the second planetary gear set from the third planetary gear set so that the second motor/generator may drive the output member while disconnected from the first motor/generator and the input member.

    摘要: A powertrain incorporates two electrical units, two planetary gearsets in a radially-stacked package to provide a shortened length of the transmission. The output members of the electrical units are interconnected by a gear mechanism, which is drivingly connected with a conventional differential mechanism, which is aligned within the radial package of the electrical units. The electrical units combine with power from an engine to provide a two-mode compound-split electrically-variable transmission.
