Title: Vehicle fluid torque transmitting unit - includes disconnectable auxiliary pump having negatively angled blades
IPC: F16H61/58
Filed: 1974-04-18
Abstract: The vehicle hydrodynamic torque transmitting unit has an auxiliary pump, that has blades with a negative bend, interposed between the bladed primary pump and turbine. The blades of the primary pump have a positive bend. When both the primary and auxiliary pumps are active, the large negative angularity of the auxiliary pump blades modifies the flow into the turbine to reduce the capacity of the unit to obtain a desired high stall torque ratio. For economical operation, a clutch can be disengaged to de-activate the auxiliary pump so that the positive blading of the primary pump directs fluid into the turbine at an optimum angle for increased capacity and high coupling efficiencies at higher speed ratios.
