Abstract
A clutch assembly for a motor vehicle drivetrain for coupling coupling elements for conjoint rotation includes a clutch unit, a brake unit and at least one permanent magnet between the clutch unit and the brake unit. The clutch unit is shiftable into a coupling state in which the coupling elements are coupled to one another by shifting the clutch unit from a first position in which the coupling elements are decoupled into a second position in which the coupling elements are coupled. First and second electrically energizable coils are electrically energizable to move the permanent magnet from the first position into the second position or vice versa. A holding plate is located adjacent to the at least one permanent magnet to suppress magnetic flux from the at least one permanent magnet to the brake unit. A motor vehicle drivetrain containing at least one clutch assembly is also provided.
