A hydrodynamic clutch arrangement, particularly a torque converter or fluid coupling, includes a housing arrangement, a turbine wheel provided in the housing arrangement, and a lockup clutch arrangement by which a torque transmitting connection can be produced selectively between the turbine wheel and the housing arrangement. The lockup clutch arrangement includes at least two friction members which are rotatable with one of the housing arrangement and turbine wheel, and at least one counter-friction member which is interposed between the two friction members and is rotatable with the other of the housing arrangement and turbine wheel. A first friction facing on at least one of the friction members at its first side faces the at least one counter-friction member. This at least one of the friction members can be brought into frictional interaction, via a second friction facing, with another counter-friction member on its second side located opposite to the first side. The first friction facing has a larger friction surface area than the second friction facing.

1. A hydrodynamic clutch arrangement comprising a housing arrangement, a turbine wheel in said housing arrangement, and a lock-up clutch arrangement for selectively producing a torque transmitting connection between the turbine wheel and the housing arrangement, said lock-up clutch arrangement compr
1. A hydrodynamic clutch arrangement comprising a housing arrangement, a turbine wheel in said housing arrangement, and a lock-up clutch arrangement for selectively producing a torque transmitting connection between the turbine wheel and the housing arrangement, said lock-up clutch arrangement comprising two friction members which are rotationally fixed with respect to one of said housing arrangement and said turbine wheel, each said friction member having a first side and an opposed second side, said first sides being mutually facing, each of said friction members having a first friction facing on said first side, a first counter-friction member which is interposed between said friction members and is rotationally fixed with respect to the other of said housing arrangement and said turbine wheel, said first counter-friction member having opposing sides which can frictionally engage respective said friction facings on respective said first sides of said friction members, a second counter-friction member adjacent to the second side of one of said friction members, and a second friction facing between said second counter-friction member and said second side of said one of said friction members, wherein said first friction facing on said one of said friction members has a substantially larger surface area than the second friction facing. 2. A hydrodynamic clutch arrangement as in claim 1 wherein said second friction facing is provided on the second side of said friction members. 3. A hydrodynamic clutch arrangement as in claim 1 wherein said second counter-friction member comprises said housing arrangement. 4. A hydrodynamic clutch arrangement as in claim 1 wherein said first and second friction facings have substantially annular shapes, said first friction facing having a larger radial dimension than said second friction facing. 5. A hydrodynamic clutch arrangement as in claim 1 further comprising a third counter-friction member adjacent to the second side of the other of said friction members, and a third friction facing between the third counter-friction member and the second side of the other of said friction members, wherein said first friction facing on the other of said friction members has a substantially larger surface area than the third friction facing. 6. A hydrodynamic clutch arrangement as in claim 5 wherein said third friction facing is provided on the second side of said other of said friction members. 7. A hydrodynamic clutch arrangement as in claim 5 wherein said first and third friction facings have substantially annular shapes, said first friction facing having a larger radial dimension than said second friction facing. 8. A hydrodynamic clutch arrangement as in claim 5 further comprising a pressing element for bringing said friction members and said counter-friction members into mutual engagement, said third counter-friction element comprising said pressing element. 9. A hydrodynamic clutch arrangement as in claim 8 wherein said housing arrangement, said pressing element, and said first counter-friction member are coupled together for common rotation. 10. A hydrodynamic clutch arrangement as in claim 9 wherein said friction members are coupled to said turbine wheel for common rotation.
