The transmission has a plurality of members that can be utilized in powertrains to provide nine forward speed ratios and one reverse speed ratio. The transmission includes four planetary gear sets, six torque-transmitting devices and four fixed interconnections. The powertrain includes an engine and torque converter that is continuously connected to one of the planetary gear members and an output member that is continuously connected with another one of the planetary gear members. The six torque-transmitting devices provide interconnections between various gear members, and the transmission housing, and are operated in combinations of three to establish nine forward speed ratios and one reverse speed ratio.

A condition of impaired speed and torque control of a parallel electrically variable transmission due to factors beyond nominal modeling and estimation errors is diagnosed under low speed operation. The transmission includes at least one electric machine and a motor torque controller for regulating the transmission input speed and output torque. The motor torque controller includes an open-loop control path based on predetermined torques and accelerations and a closed loop control path based on input speed error. The presence of a larger than expected closed-loop correction magnitude, combined with low output speed and one or more other conditions is used to diagnose a condition of potential torque error, in which case the transmission control is altered to prevent unwanted operation.

The invention relates to a pumping device for introduction of a fluid into a base layer, in particular into a base layer containing gas, for the production of gas-permeable structures in the base layer. The pumping device is arranged on a transportation vehicle having a separate drive unit, including a pump motor and a pump, whereby a speed/torque converter is arranged between pump and pump motor. A hydrodynamic device, in particular a hydrodynamic converter, is used in place of a transmission for speed/torque conversion.

The torque tool comprises a torque converter including three planet carriers which encase three planetary gears. Each of the three planetary gears includes a sun gear and three planet pinions. Each of the three planet carriers has an input disc-shaped plate, directed towards an input shaft of the torque tool and an output disc-shaped plate directed towards an output shaft of the torque tool. The input and output shafts constitute the main shafts of the torque tool. Two of the three planet carriers, which are next to the input shaft, have their output disc-shaped plates extending into sun gears with which they form unitary structures. A stepped pin is centrally disposed in a needle bearing of a first sun gear adjacent the input shaft and extends through sliding bearings located in the following sun gears. A first large diameter of the stepped pin is commensurate with an interior diameter of the needle bearing and a second small diameter of the stepped pin is commensurate with interior equal diameters of the sliding bearings inserted in the following sun gears. The planet pinions of one of the three planet gears, which is adjacent to the output gear, arc each provided with a multiplicity of roll needles closely spaced together, the multiplicity of roll needles being inserted between each of the at least three planet gears and an axle for supporting.
