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. In the direct circulation functional mode of the operating fluid, the supply of the lubricant supply system between the outlet and the inlet is effected solely from the direct circulation.
