Centrifugally optimised clutch plate carrier
The centrifugally optimised clutch plate carrier is a variant of the clutch plate carrier in which the internal spline can be used right up to the open end while a reinforcing radial ring still remains at the open end of the carrier. Ernst Grob produces it by internal forming on the i9 machine or by intermittent forming on the T12. This enables a simpler and more stable component.
What is a centrifugally optimised clutch plate carrier?
It is a variant of the clutch plate carrier for automatic transmissions. The internal spline can be used right up to the open end of the component while a reinforcing radial ring still remains at the open end of the carrier, resulting in a simpler and more stable part.
- Stiffening ring at the open end to increase rigidity at high rotational speeds (centrifugally optimised).
- Spline up to the open end: This allows a simpler and more stable component to be produced.

Manufacturing at Ernst Grob
Production takes place by internal forming on the i9 machine or by intermittent forming on the T12, optionally with slotting as a follow-up step on the S8. Materials and basic principle correspond to the clutch plate carrier.
