ABSTRACT:
A bridging clutch for a hydrodynamic torque converter which is designed with at least one friction area on a first converter component, which area can be shifted into working connection with at least one opposing friction area provided on a second converter component by means of an engaging movement or which can be separated from this second component by a disengaging movement in the direction opposite to the engaging movement. At least one of the two converter components acts as a friction lining carrier, which carries a friction lining in the friction area or in the opposing friction area, at least one opening being provided in the friction lining to allow the passage of transport medium, the inflow area of the opening being on the same radial side of the friction lining as its outflow area. On at least one of the converter components serving as a friction lining carrier, at least one friction lining is provided with an opening, which, on the radial side with the inflow area and the outflow area, is open continuously over its entire extent in the circumferential direction of the friction lining.
