New machining strategies for a hollow camshaft
The camshaft is used to open the intake and exhaust valves according to the design timing. The shaft rotates around its own axis – this rotary movement is repeatedly converted into a short longitudinal movement by the cams mounted on it.
Use of cold forming for optimum results
This Felss camshaft was developed together with a customer and was the first time that active cylinder management was implemented in a large-scale production four-cylinder engine. When less power is required, the vehicle’s active cylinder management system therefore automatically switches to a mode in which only two cylinders operate. This automatically increases efficiency and reduces fuel consumption. On average, the car saves 15% on gasoline.
Special features of the realized solution
- Greater degrees of forming without the use of heat-based processes
- Fuel savings in the application thanks to the option of individual cylinder deactivation
- More precise toothing and material hardening through work hardening
- Suitable for series production through the use of proven processes
