Abstract
A hydrodynamic coupling device including: a housing; a sealing plate rotationally connected to the housing; a pump disposed within the housing; a turbine disposed within the housing and in fluid communication with the pump; and a dry chamber at least partially enclosed by the housing and the sealing plate. A hydrodynamic coupling device including: a housing; an electric motor rotationally connected to the housing; and a fluid coupling including a pump rotationally connected to the housing and a turbine rotationally connected to an output hub. The fluid coupling does not include a stator. A hydrodynamic coupling device including a space formed between a stator shaft and a pump hub and a sleeve disposed in the space. The sleeve divides the space into first and second channels.
