  • Publication number: 20220145971
    Abstract: A propulsion system for an electric vehicle including an internal combustion engine and an electric machine disposed in a transmission housing that is attached to the engine. An engine vibration damper is disposed between the engine and the electric machine. A torque converter connects the engine to the turbine shaft and is disposed in the housing radially inboard of the windings of the electric machine. A turbine shaft connected to the electric machine is configured to transfer torque from the engine and the electric machine through the turbine shaft to a planetary gear set connected to the turbine shaft. A disconnect clutch is operatively connected between the engine and the electric machine and is disposed in the housing radially inboard the windings of the electric machine and is connected to the turbine shaft.

  • Patent number: 8882468
    Abstract: A blade family for torque converters with a first blade having a first shape and flow guiding surface and a second blade having a second shape and flow guiding surface. The first surface is different from the second surface and the first shape is the same as a portion of the second shape, or the second shape is the same as a portion of the second shape. In an example embodiment of the invention, at least one of the first or second blades includes holes or slots. In an example embodiment of the invention, the first blade includes more material than the second blade. The first and second blades may have respective mounting tabs, with the second blade having fewer mounting tabs than the first blade. Other example aspects of the present invention broadly comprise a torque converter with a plurality of first and/or second blades from the blade family.

  • Patent number: 7887240
    Abstract: A thrust washer for a torque converter, including a front surface and at least one first channel. The at least one channel is at least partially enclosed by the front surface and is in fluid communication with an inner circumference and an outer circumference for the thrust washer. The front surface is arranged to engage a cover for the torque converter. In some aspects, the at least one channel is fully enclosed by the front surface. The thrust washer also includes a back surface, oppositely disposed from the front surface. The at least one channel is at least partially enclosed by the back surface. In some aspects, the thrust washer includes a front piece and a back piece matingly engaged and configured to form the at least one channel. The front and back pieces are fixedly secured or removably secured.

  • Publication number: 20090155078
    Abstract: The invention relates to a more efficient and cost effective method of bonding pump blades and a pump hub to an impeller of a torque converter by the steps of initially assembling the pump blades and the pump hub adjacent and in close proximity to the impeller and bonding the pump hub and the pump blades to the impeller simultaneously while also eliminating the potential for surface defects through multiple heating steps. The invention includes the more efficient methods of manufacturing, but also the brazed/welded assemblies and torque converters comprising the assemblies.
