  • Method for supplying bearing components of a hydrodynamic clutch with lubricant and corresponding hydrodynamic clutch
    Patent number: 7343739
    Abstract: A method for the supplying bearing elements in a hydrodynamic coupling: The coupling includes a primary wheel and a secondary wheel, which together form a working area capable of being filled with operating fluid. An operating fluid system having a direct circulation connecting at least one outlet from the working area to an inlet into the working area. A filling line connectable at least indirectly to the operating fluid source. An emptying line connecting the outlet at least indirectly to the operating fluid source. The filling line and the emptying line are connected via the direct circulation to the inlet and the outlet, together with a lubricant supply system, which is capable of connection to the filling line, and which is supplied with lubricant during all operating modes. At least during the filling mode, the supply of lubricant is via the filing line that is capable of connection to the operating fluid source.
