Abstract
Official abstract text for this publication.
The invention relates to an auxiliary drive device (1) comprising an electric motor (10, 11); and a mechanical clutch, wherein the electric motor (10, 11) and the mechanical clutch have the same axis of rotation (R), the mechanical clutch is designed as a fluid-friction clutch (20), and the electric motor (10, 11) and the fluid-friction clutch (20) are mechanically connected to one another.
First claim
Opening claim text (preview).
The invention claimed is: 1. An auxiliary drive device comprising an electric motor having a rotor, which is rotatable about an axis, and a stator that is received within the rotor; and a viscous clutch having a housing, a clutch disk and a reservoir, the housing being coupled to the rotor for common rotation about the axis, the clutch disk being received in the housing and being rotatable about the axis relative to the housing, the housing and the clutch disk forming a working chamber, the reservoir being coupled in fluid communication to the working chamber. 2. The auxiliary drive of claim 1 , wherein the fluid-friction clutch includes a bidirectionally functioning drainage pump that fluidly couples a radially outward end of the working chamber to the reservoir. 3. The auxiliary drive of claim 2 , wherein the drainage pump includes two drainage pumping elements that are incorporated into the housing opposite one another, the drainage pumping elements being coupled to the housing and being in fluidic connection with assigned drainage pump channels, the drainage pump channels extending toward the reservoir.
