Abstract: An automatic transmission consisting of a housing to support multiple torque converters in series with each other. The housing is used to align the converters, direct the output of the first converter to the second and so on. The housing also provides paths for the fluid to enter and leave the converter and to operate the lock-up feature of each converter. The output of each torque converter turbine is fed to the next torque converter so that the next converter can further act on the ratio as needed until the final output is fed to a gear set to provide a reverse gear or locking mechanism.

Abstract: A power transmission unit with at least one driving shaft that can be coupled to a driven machine includes a modular hydrodynamic coupling unit. The coupling unit includes at least two blade wheels, which together form at least one toroidal working chamber. The two blade wheels each can be connected non-rotatingly to a hub-like element, which can be connected non-rotatingly with one of the driving shaft or driven shaft. An intermediate hub is disposed between at least one blade wheel and a corresponding hub-like element. The intermediate hub is coupled non-rotatingly to the blade wheel and extends in the axial direction from the blade wheel at least to directly above an axial end wall of the housing of the coupling unit. The intermediate hub is removably securable to the coupling housing. The hub-like element forms at least one axial stop for the intermediate hub when it is mounted in the housing.

Abstract: A three element, three phase hydrodynamic torque converter having improved structural and hydrodynamic characteristics, and automatic transmissions that use a plurality of such hydrodynamic torque converters as replacements for multiple disc wet clutches or the like to effect transmission ratio changes. The hydrodynamic torque converters use a centrifugal impeller and a centrifugal turbine on the forward axial side of the torque converter, and a centripetal stator mounted to the converter shell on the rearward axial side. Three phase operation results when using the specified geometries: [1] torque multiplication, where the speed ratio i=n.sub.t /n.sub.p is greater than one; [2] coupling phase, where the speed ratio approaches one; [3] extension phase, where the speed ratio equals one and then exceeds one. For operation with speed ratio i=n.sub.t /n.sub.p in the range 0.6 .ltoreq.i .ltoreq.1.3, operational efficiency .eta. is found to be between 82 and 88 percent.

Abstract: A multiple stage energized fluiel flywheel is contained within a housing. An axially extending shaft is rotatably mounted within the housing. Fluid is introduced into the unit through an initial axial flow section and further pressure increases are experienced in a radial blower section and an annular squirrel cage section peripherally arranged about the radial blower. Pressurized fluid discharged from the squirrel cages is directed to either a peripheral exhaust ring which discharges pressurized fluid to the reservoir interior or to an adjacent hydraulic motor. The hydraulic motor includes a rotor which is secured to the stator section of the initial axial pumping section. The axial shaft, radial blower, squirrel cage and exhaust section rotate as a unit in one direction of operation. The hydraulic motor and axial pumping section stator rotate as a unit in the opposite direction of rotation. The flywheel may operate using air, hydraulic fluid or other motive fluids.

Abstract: This invention describes an improved type of hydromatic brake in which the stators and rotors are prepared as individual items and the assembly is designed so that one, two, three or more sets of individual stators and rotors can be assembled inside a housing.

When more than one stator is used an additional tubular flanged spacing element is provided, and two stators are clamped, one on each end of the annular tubular spacing element and the end walls are clamped to the stators. A second important feature of this invention lies in the design of the stator which carries an overhanging lip or peripheral rim into which the rotor fits. There is a selected radial clearance between the outer circumference of the rotor and the inner radius of the lip.
