ABSTRACT:
The invention relates to a viscous coupling 1 in the case of which one of the two coupling parts, i.e. either the coupling hub 9 or the coupling housing 2, is produced of plastics. To permit non-rotating accommodation of the associated coupling plates 11 or 12, metallic round bars 18 are embedded in the plastic coupling part 2 or 9 so as to be circumferentially distributed. The inner circumference or the outer circumference of the associated coupling plates 11, 12 is provided with an adapted profile. This measure ensures that in spite of the high loads occurring in the course of the transmission of torque it is possible to use plastic parts.
