LOCKUP CLUTCH FOR HYDRODYNAMIC COMPONENTS

摘要

The invention relates to a lockup clutch ( 1 ) for hydrodynamic components ( 2 ), comprising at least one primary wheel ( 4 ) and one secondary wheel ( 5 ), which define a working chamber ( 6 ), and having two inputs ( 26, 27 )-a first input ( 26 ) linked to the secondary wheel ( 5 ) and a second input ( 27 ) linked to the primary wheel ( 4 ). Said inputs ( 26, 27 ) can be optionally linked to an output ( 28 ) of the lockup clutch ( 1 ) via a switchable clutch, thereby producing a first or a second power branch ( 32, 33 ). The coupling between the input ( 27 ) of the lockup clutch ( 1 ) that is coupled to the primary wheel ( 4 ) and the output ( 28 ) of the lockup clutch ( 1 ) in order to create the second power branch ( 33 ) is free of any rotationally fixed mechanical connection between the primary wheel ( 4 ) and the secondary wheel ( 5 ). The coupling between the inputs ( 26, 27 ) of the lockup clutch ( 1 ) and the output ( 28 ) of the lockup clutch ( 1 ) in the individual power branches ( 31, 33 ) is provided with rpm/torque converting devices.
