ABSTRACT:
The invention relates to a viscous coupling such as it used in the driveline of a motor vehicle, wherein, due to a relative rotational movement between the inner plates 80 and the outer plates 90, the viscous medium is made to flow towards the axis of rotation X--X of the viscous coupling. To achieve this objective, the plates 80, 90 are provided with closed apertures 81, 91, whose delimiting faces 82, 83, 92, 93 are inclined relative to an imaginary radius R, so that, in the case of a rotational movement, the delimiting faces press the viscous medium inwardly, independently of the direction of rotation. This counter-acts a separation of viscous medium and air often caused by centrifugal forces at high speeds. As a result, the plates 80, 90 are moistened uniformly, which, in turn, reduces the amount of wear and increases the service life of the viscous coupling.
