Abstract
A hydrokinetic torque converter which includes pump wheels and/or turbine wheels in particular of a Fottinger coupling, wherein all the required blades are stamped in the form of blade blanks, out of a round stamping blank in a single operating process, in such a manner that each blade blank remains connected, by means of a connecting web, to a ring-shaped area of the stamping blank which remains intact during the stamping. The blade blanks are then subjected to a shaping process, in which they are reshaped into the final three-dimensional shape of the blade, whereby the connection with the ring-shaped area remains intact, and, in a shaping process, the ring-shaped area is adapted to the contour of the housing that delimits the pump wheel or turbine wheel. A blade carrier is thereby produced which makes it possible to install all the blades, in their three-dimensional position with respect to the pump or turbine wheel, in a single process.
