Abstract

The invention relates to the production of a multi-part hub part for a clutch disc, wherein all parts are joined together by a weld. Different designs are possible, depending on the various welding processes. The apertures for damper springs can be produced very exactly in the hub disc owing to the production in individual parts. It is also possible to arrange lubricant reservoirs in a simple manner in the region of the points of separation of the individual components.
