Transmission applications
ElringKlinger solves the complex sealing tasks in the transmission area with high-performance, tailored systems – in hydraulic transmission controls with oil pressures of up to 80 bar or directly in the shift pistons of automatic transmissions at high circumferential speed and millions of switching operations over the service life.
Composite pistons
Automatic transmissions with a high number of gears are increasingly requiring the use of composite pistons. The special feature of ElringKlinger composite pistons is their extremely smooth surface. This ensures that the transmission controller works particularly smoothly. The switching operations take place extremely precisely and offer optimal driving comfort.
Transmission control plates
In hydraulic control units of automatic and dual-clutch transmission systems, different designs from ElringKlinger are used depending on the requirement profile: Metaloseal™, Metaloprint™ and metal-soft material transmission control plates. They seal the individual oil ducts of the controls against each other at pressures of up to 80 bar. Integrated function elements, such as ball seats for check valves, stamped flow screens or residual dirt screens help to direct the oil flows safely and precisely.
