Abstract
A seal assembly and method of making a seal assembly for a transmission that provides a plurality of pressurized fluid connections. The seal assembly is formed between two adjacent plates that have corresponding holes that include axially extending perimeter walls. An elastomeric sealing element is over molded onto a first plate to line the holes and cover the perimeter walls. The second plate is assembled to the first plate.
Claims17
An oil transfer seal assembly for a transmission having first and second transmission components defining a gap therebetween, comprising:
- a first plate having a first set of holes through which a fluid flows, the first set of holes each being formed by an axially extending perimeter wall;
- a second plate having a second set of holes corresponding to the first set of holes through which the fluid flows, the second set of holes each being formed by an axially extending perimeter wall;
- an elastomeric seal element bonded to the axially extending perimeter walls of the first set of holes;
- and
- wherein the first plate, second plate, and seal element cooperate to form a plurality of pressurized fluid connections through the first and second plates, and wherein the perimeter walls of the first and second sets of holes partially overlap and support the seal element as the seal assembly seals the gap between the first and second transmission components.
A method of making an oil transfer seal assembly comprising:
- providing a first plate and a second plate;
- forming a plurality of holes in the first and second plates in corresponding locations;
- forming an axially extending perimeter wall on each of the holes in the first and second plates;
- molding an elastomeric seal onto the perimeter wall of the holes in the first plate;
- assembling the second plate to the first plate with the axially extending walls of the second plate receiving the axially extending walls of the first plate with a portion of the elastomeric seal being disposed between the axially extending walls of the first plate and the axially extending walls of the second plate.
