Abstract

Disclosed is a torque converter (A), which comprises at least two thrust bearings (45) disposed on respective axially-opposite sides of a radially-inward portion (35) of a stator (30). The stator includes a non-rotatable member (43), a rotatable member (42) and a one-way clutch (40). The rotatable member (42) has a cylindrical portion having an inner peripheral surface interlocked with the one-way clutch (40), and an extension portion (37) which extends from an approximately axially-central region of the cylindrical portion in a radially-outward direction relative to the cylindrical portion (38), and has an axial thickness less than that of the cylindrical portion. The thrust bearings (45) are disposed to clamp the extension portion (37) from respective axially-opposite sides of the extension portion (37) at respective positions located radially outwardly relative to the cylindrical portion (38), so as to facilitate reduction in axial dimension of the torque converter.

Description

technical field [0001] The present invention relates to a hydraulic torque converter including a pump impeller, a turbine runner, and a blade, and transmitting torque from an input portion to an output portion by fluid circulating between these components. (torqueconverter), especially related to the hydraulic torque converter that tends to be compact in the axial direction. Background technique [0002] A conventionally known hydraulic torque converter includes a pump impeller in contact with an input portion, a turbine opposite to the pump impeller and in contact with an output portion, and an inner peripheral portion of the pump impeller and an inner peripheral portion of the turbine. The stator (stator) of the vane transmits the torque from the input to the output through the fluid circulating between the pump wheel, the turbine and the vanes (in the circulation area formed by them). [0003] For example, in a torque converter used in an automatic transmission of a vehi...
