Abstract
A sealing assembly for a torque converter includes a hub mounted on a drive shaft and having an axial extension portion, and a sealing member disposed between the axial extension portion of the hub and the drive shaft and arranged to seal a portion between the hub and the drive shaft. The hub further includes an inner radial extension portion extending from the axial extension portion toward the drive shaft, and the inner radial extension portion and the axial extension portion define an accommodation space for accommodating the sealing member. The above-mentioned sealing assembly can be included in a torque converter, and the torque converted can be included in a vehicle.
Claims15
A sealing assembly for a torque converter, the sealing assembly comprising:
- a hub mounted on a drive shaft and having an axial extension portion;
- and
- a sealing member disposed between the axial extension portion of the hub and the drive shaft and configured to seal a portion between the hub and the drive shaft,
- wherein the hub further comprises an inner radial extension portion extending from a first end of the axial extension portion toward the drive shaft,
- wherein the inner radial extension portion and the axial extension portion define an accommodation space for accommodating the sealing member,
- wherein the hub further comprises an outer radial extension portion extending from a second end of the axial extension portion in a direction away from the drive shaft, the second end of the axial extension portion being opposite to the first end in an axial direction.
