Fluid-friction coupling and its use

Abstract

Abstract A fluid-friction clutch consists of a housing (1) filled with fluid, a shaft (2) projecting therein and inner and outer plates (3, 4) which engage with one another and are connected in a rotationally fixed manner alternately to the shaft (2) and to the housing (1). Annular expansion springs (5) are inserted between the inner or outer plates (3, 4). The plate separation can be varied by means of a ring piston (7) which can be operated from the exterior. …<??>In order to achieve controllability of the fluid-friction clutch within wide limits, the ring piston (7) has, on its side facing the plates (3, 4), a plane surface (8), which extends approximately over the complete free housing cross-section, reaches up close to the plates (3, 4) and is at right angles to the axis. In addition the filling level of the housing (1) in the outermost piston position is at most 60% and a fluid with a viscosity of at least 30,000 cSt is selected. …<IMAGE>…
