Clutch Piston Assembly |
| 摘要 |
The clutch piston assembly includes a one piece piston body which extends about an axis and has at least one radially inwardly facing surface and at least one radially outwardly facing surface. At least one seal is engaged with the piston body and extends either radially outwardly from the radially outwardly facing surface or radially inwardly from the radially inwardly facing surface. The seal is made of polyetheretherketone (PEEK) or polyaryletherketone (PAEK) for establishing a low friction and fluid tight seal between the piston body and a wall in the automatic transmission. |
