Abstract
A viscous coupling comprising two parts which are supported inside one another, which are rotatable around a common longitudinal axis and which form an annular chamber which is filled with a highly viscous medium and in which there are arranged inner plates which are non-rotatably connected to the inner one of the parts and form a set of inner plates, as well as outer plates which are non-rotatably connected to the outer one of the parts and form a set of outer plates, said inner plates and outer plates being arranged so as to alternate in the longitudinal direction for the purpose of generating a coupling effect between the two parts when the latter rotate relative to one another, wherein a partial set of one of the sets of inner plates and outer plates is directly carried by a sleeve which is connected to the part of the coupling which carries said set of inner plates or outer plates in such a way that it can be uncoupled.
