Precision parts for drive shafts

Ball hubs for drive shafts -ready-to-install-

metallumform manufactures ready-to-install ball hubs for cardan shaft components and base bodies of torques (homokinetic joints).

Cardan shafts are used for the purpose of transmission of torques for misaligend rotation axis. These products are used for automobiles and commercial vehicles.

Manufacturing flow:

  1. Raw part production by means of hot forming
  2. Heat treatment by means of controlled cooling process direct from forge quench treatment
  3. Mechanical processing (e.g. milling)
  4. carbonizing
  5. statistical process control

Special features:

These components groups stand out and feature a continious component optimization in connection with our long-term partnership with customers. A specific focus on the fields of productions, enable us to perform an optimal and flexible manufacturing strategy. Shipping system of just in time delivery, KANBAN method.


Ball hubs -turned parts-

External ring drive shaft

metallumform manufactures external rings for cardan shaft components (homokinetic joints).

Manufacturing flow:

  1. Raw part production by means of hot forming
  2. heat treatment by means of controlled cooling process direct from forge quench treatment
  3. mechanical processing

Tripods

metallumform manufactures finished tripods, which are installed as interior components of automobile CV joints in drivetrains.

Manufacturing flow:

  1. Precision sawing of a cylindrical section
  2. coating for forging
  3. semi-hot forging in a closed die forging process (lateral extrusion)
  4. mechanical processing

Special features:

Forging by means of lateral extrusion of tripods leads to a highly favorable fiber orientation of the component structure. Thus a positive impact is set on the features of wear and mechanical firmness. Furthermore, only a few further lathe machining fabrication steps are necessary in order to achieve the final state.
