TORQUE CONVERTER

摘要

In a torque convertor including a pump impeller, a turbine runner and a stator, an outer regulation surface facing inwards in a radial direction is provided at a turbine shell on an inward side in the radial direction from a turbine blade, an inner regulation surface that approaches and faces the outer regulation surface from inside in the radial direction is provided at a stator hub, and at least one of the outer regulation surface and the inner regulation surface is formed into a ring shape. Accordingly, movement of the stator along the radial direction at a time of transportation is inhibited and it is made unnecessary to form flange portions at core rings of the pump impeller and the turbine runner.

1. A torque converter comprising:
a pump impeller in which a plurality of pump blades are provided on an inner surface of a pump shell having an inner peripheral portion fixedly provided at a pump hub; a turbine runner in which a plurality of turbine blades are provided on an inner surface of a turbine shell having an inner peripheral portion fixedly provided at a turbine hub that is disposed at a space in an axial direction from the pump hub; and a stator in which a plurality of stator blades are provided at an outer periphery of a stator hub and thrust bearings are respectively interposed between the pump hub and the stator hub and between the turbine hub and the stator hub, wherein an outer regulation surface facing inwards in a radial direction is provided at the turbine shell on an inward side in the radial direction from the turbine blade, an inner regulation surface that approaches and faces the outer regulation surface from inside in the radial direction is provided at the stator hub, and at least one of the outer regulation surface and the inner regulation surface is formed into a ring shape.
