Abstract

A viscous coupling may include: a housing part and an input body rotatable relative to the housing part that at least partially delimit an interior space; a shaft rotatable relative to the housing part and on which an output body arranged in the interior space may be formed for conjoint rotation with the shaft; a coupling region formed between the output and input bodies and configured to hold a viscous fluid to assure a coupling between the input body and the output body; a holding chamber for collecting coolant leaking from the coolant pump; a housing wall conformed integrally with the housing part and partially delimiting the holding chamber; and an actuator housing and an electric actuator therein by which a degree of the coupling between the input body and the output body may be adjustable. The actuator housing may at least partially cover the holding chamber.
