ABSTRACT:
A fluid friction coupling includes a housing defining a work chamber and rotatably journalled on a drive shaft. The housing contains a viscous medium and a drive disc for transmitting torque to said housing via fluid friction in the viscous medium. The housing has an inner housing part having a first peripheral edge and an outer housing part having a second peripheral edge. The peripheral edges conjointly define a form-tight interlocked interface. A plurality of raised portions and a plurality of recesses between the raised portions are provided on one of the peripheral edges. The other peripheral edge is a flange having a periphery and the flange has a plurality of outermost edge regions along the periphery. The outermost edge regions on the one hand and the raised portions and the recesses on the other hand are joined together to conjointly define the form-tight interlocked interface.
