Abstract
Official abstract text for this publication.
A rotor hub includes a sheet metal cylinder including spline teeth including angularly spaced crests and valleys, a tube surrounding the cylinder, secured to the crests and supporting a rotor thereon, a hub secured to the cylinder and supported for rotation, a torque converter, and a flex plate secured to the hub and the torque converter.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotor hub, comprising: a sheet metal cylinder including spline teeth including angularly spaced crests and valleys; a tube surrounding the cylinder, secured to the crests and supporting a rotor thereon; a hub secured to the cylinder and supported for rotation; a torque converter; a flex plate secured to the hub and the torque converter. 2. The rotor hub of claim 1 , wherein the tube and splines define first channels, the cylinder being formed with holes, each hole extending through one of the valleys and communicating with one of the first channels, the tube being formed with drain holes, each drain hole communicating with one of the first channels. 3. The rotor hub of claim 2 , wherein the rotor includes second channels, each second channel communicating through one of the drain holes with one of the first channels. 4. The rotor hub of claim 3 , wherein the first channels and the second channels are directed along an axis of rotation. 5. The rotor hub of claim 3 , further comprising end plates, each end plate being located at an opposite end of the rotor and formed with radial passages, each passage communicating with one of the second channels. 6. The rotor hub of claim 5 , wherein the passages are directed radially with respect to an axis of rotation. 7. The rotor hub of claim 1 , wherein the tube is one of a seamless tube and the tube having a continuous welded seam. 8. The rotor hub of claim 1 , further comprising: a clutch piston located in the cylinder; clutch plates engaged with the spline teeth and able to be actuated by the piston. 9. A rotor hub, comprising: a sheet metal cylinder including spline teeth including angularly spaced crests and valleys; a tube surrounding the cylinder, secured to the crests and supporting a rotor thereon; a hub secured to the cylinder and supported for rotation. 10. The rotor hub of claim 9 , wherein the tube and splines define first channels, the cylinder being formed with holes, each hole extending through one of the valleys and communicating with one of the first channels, the tube being formed with drain holes, each drain hole communicating with one of the first channels. 11. The rotor hub of claim 10 , wherein the rotor includes second channels, each second channel communicating through one of the drain holes with one of the first channels. 12. The rotor hub of claim 11 , wherein the first channels and the second channels are directed along an axis of rotation. 13. The rotor hub of claim 11 , further comprising end plates, each end plate being located at an opposite end of the rotor and formed with radial passages, each passage communicating with one of the second channels. 14. The rotor hub of claim 12 , wherein the passages are directed radially with respect to an axis of rotation. 15. The rotor hub of claim 9 , wherein the tube is one of a seamless tube and the tube having a continuous welded seam. 16. The rotor hub of claim 9 , further comprising: a clutch piston located in the cylinder; clutch plates engaged with the spline teeth and able to be actuated by the piston.
