Problems solved by technology

Also, the flow of axial force between the turbine and the impeller of the torque converter is not shut off, which causes the impeller to push the flexplate that connects the torque converter to the engine crankshaft
Also, the design shown by Jatco requires complex assembly to slide the snap ring over the stator shaft and into its slot when installed in the gearbox

Abstract

A torque converter, including: a cover arranged to receive torque; an impeller including an impeller shell non-rotatably connected to the cover; a turbine in fluid communication with the impeller and including a turbine shell; a stator at least partially located between the impeller and the turbine; and including a body portion with at least one stator blade and a first frusto-conical surface; a stator cone clutch including the first frusto-conical surface and a flange including a second frusto-conical surface; and a first thrust bearing axially disposed between the stator cone clutch and the impeller shell. In a stator locked mode: the body portion and the flange are non-rotatably connected; and the stator cone clutch is arranged to urge the first thrust bearing against the impeller shell in a first axial direction.

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C. §119(e), this application claims priority to U.S. Provisional Patent Application No. 62 / 076,986, filed November 7, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to a torque converter, and more particularly to a torque converter having a stator including a cone clutch and bearings for transferring thrust from the stator to an impeller housing. Background technique [0004] Patent application WO 2014 / 098353 (Jatco) discloses a typical cone clutch for a stator in a torque converter. In a typical torque converter using a stator with a cone clutch, during the stator lock mode, the cone clutch is closed to non-rotatably connect the stator to the stator shaft and the axial force generated by the fluid flowing over the stator vanes The thrust acts through the stator and the stator shaft. Since the stator shaft is fixed t...
