Pump runner module, for hydrodynamic coupling device has projection on each pump runner scoop with indentation into which reaches material of pump runner shell after deformation process

摘要

A pump runner module, especially for a hydrodynamic coupling device comprises a pump runner shell (20) on which in the peripheral direction about a central axis, a number of pump runner scoops (28) are provided following one another, each pump runner scoop having a number of projections (78) extending in a longitudinal direction of the scoop. On the pump runner shell, a recess (70) is provided for each of the projections into which this reaches. At least one of the projections of each pump runner scoop has an indentation (86) in one of its extension end regions into which reaches material of the pump runner shell surrounding this projection after execution of a deformation process.
