Coreless torque converter for motor vehicles - has curved pump wheel and/or turbine wheel blades with curved side faces and set at angle in rotary direction.

摘要

The curved blades of the pump wheel (2) and/or turbine wheel (5) produce a predetermined inlet angle and a predetermined outlet angle. The blades are inclined by an angle of 15 to 60 deg. The side faces of the wheels are curved from the radially outer end to the radially inner end so that they are convex opposite the rotary direction of the pump wheel. The fluid loss is reduced and the loss of pressure as a result of a collection of low energy fluid is also reduced. USE/ADVANTAGE - High efficiency torque converter with high transfer ratio.
