Abstract
A regulating device (2) for a viscoclutch (4) which is provided with a primary disc (6) and a secondary disc (8), the primary disc having a first rotation speed (10) and the secondary disc a second rotation speed (12). The regulating device (2) receives signals which represent the rotation speeds and a desired degree of engagement (14), and calculates a prevailing degree of engagement (15) between the discs (10). The degree of engagement between the discs is controlled by regulating an amount of viscous oil between them by delivering a control signal (16) to an oil pump unit (18) which pumps oil (20) into the viscoclutch (4). The nature of the engagement, and controlling for maximum to minimum engagement is disclosed.
