What is Viscous Coupling?
It is a type of a clutch where fluid friction provides the coupling and decoupling action. Simply put, in a normal clutch, you have a clutch disk and a metal plate sandwhiched together. To couple them, spring pressure is applid to squeeze the clutch disk and the metal plate together. To decouple, you defeat the spring pressure (for example, you push the clutch pedal in) In a viscious coupler, you have thin clutch plates with holes in them. Arranged in a way so that every other one is connected to the oppasite shaft (input /output). These clutch plates are contained in a specially designed container that fits around them, holds pressure, IS FILLED WITH AN EXTREMMELLY VISCIOUS fluid (usually a silicon), and allows the input to turn independant of output. When one side turns FASTER then the other, the holes in the clutches start causing massive friction in the fluid, which causes the fluid to get hot. When it gets hot, it becomes more viscious AND increases in pressure. This essentially f
