Torque converter with internally reversible turbine shaft.

摘要

Gearing is normally used to obtain reverse operation from an output turbine. An improvement is provided herein in a torque converter (10) which comprise a stator (12), an impeller (14) and an output turbine (16). The improvement comprises a plurality of self-cambering blades (42) carried by the output turbine (16) with the angle at which fluid impelled by the impeller (14) attacks the self-cambering blades (42) being adjusted to select the direction of rotation of the output turbine (16). In this manner, the output shaft (36), which is driven by the output turbine (16), can be rotated in either a clockwise or a counterclockwise direction thereby driving a vehicle or other machinery in either a forward or reverse direction without the necessity for gearing.
