Planetary Assembly
Benefit: Cost Saving, Increased Component Complexity
Main Forming Process: Conventional Processing
End Use Sector: Automotive
Material: Ferrous


This part is assembled in the transmissions of the Volkswagen Touareg and the Porsche Cayenne, where it supports the planetary gears used in the transfer case of 4WD vehicles. In any of the 6 holes, a shaft is fitted, where planetary gears are turning. The part only works when the short speeds are connected. In any other case, the part is turning free without any work. So the part is acting as a speed reduction of the transmission shaft.


PM offers the possibility to join parts during sintering. In this case, a sinter-brazing technique is used to join the front and the rear during sintering, so a joining step is saved. Given the complex shape of the part its compactness and dimensional accuracy, PM technology offers the customer many economic savings.
