Abstract

Official abstract text for this publication.

A compact integrated torque converter assembly is disclosed herein. The integrated torque converter assembly includes a clutch assembly that is integrated with a core ring arrangement. Based on this arrangement, the clutch assembly is positioned inside of the torus and radially inward from a radially outward periphery of the pump and the turbine.

First claim

Opening claim text (preview).

What is claimed is: 1. An integrated torque converter assembly comprising: a pump and a turbine arranged adjacent to each other to define a torus; a core ring arrangement positioned within the torus; a clutch assembly supported by the core ring arrangement; a three-passage hydraulic fluid arrangement including: an inlet passage; an outlet passage; and a control passage, the control passage providing hydraulic fluid directly to an axial outer surface of the turbine; and a seal always contacting a radially outer surface of the turbine and a radially inner surface of the pump such that the seal separates the control passage from the clutch assembly and the torus. 2. The integrated torque converter assembly of claim 1 , wherein the clutch assembly includes a plurality of friction plates. 3. The integrated torque converter assembly of claim 2 , wherein the clutch assembly further includes a pair of clutch plates connected to a first axially extending flange of a first core ring half of the core ring arrangement, and a separator plate connected to a second axially extending flange of a second core ring half of the core ring arrangement, wherein the plurality of friction plates are arranged between the pair of the clutch plates and the separator plate. 4. The integrated torque converter assembly of claim 3 , wherein the pair of clutch plates are connected to the first axially extending flange via a first splined connection, and the separator plate is connected to the second axially extending flange via a second splined connection. 5. The integrated torque converter assembly of claim 1 , wherein the clutch assembly is positioned radially inward from a radially outward periphery of the pump and the turbine. 6. The integrated torque converter assembly of claim 1 , wherein the core ring arrangement is formed from stamped steel. 7. The integrated torque converter assembly of claim 1 , wherein the clutch assembly overlaps with a medial region of the torus in both an axial direction and a radial direction. 8. The integrated torque converter assembly of claim 1 , wherein the control passage includes a portion that is defined radially inward from the inlet passage and the outlet passage.
