Electromagnetically actuable clutch arrangement

A clutch arrangement, for a drive train of a motor vehicle, for coupling a first clutch section to a second clutch section, comprising:

• at least one pin-shaped shift element which is mounted so as to be movable in a direction of a longitudinal axis thereof between an engaged position, in which the two clutch sections are coupled for conjoint rotation by means of the shift element, and a disengaged position, in which the two clutch sections are decoupled from one another;
• at least one spring which acts at least indirectly on the shift element and preloads the shift element in a direction of the engaged or disengaged position;
• and
• an electromagnet in an energized state which moves the shift element counter to a preloading effect of the spring;
• and
• a movable shifting device which carries a plurality of the shift elements and is arranged on the first clutch section, wherein the spring acts indirectly via the shifting device or directly on the shift elements in order to preload the shift elements in the direction of the engaged or disengaged position thereof;
• wherein the shifting element further comprises an impulse element axially movable relative to the shifting device and relative to the electromagnet, wherein the impulse element is preloaded in a direction away from the electromagnet by means of at least one further spring which is supported on the shifting device, and wherein a preloading effect of the at least one further spring is less than the preloading effect of the spring which acts on the shift elements.

• wherein each of the shift elements has a flange, wherein the flange includes a collar surrounding a distal end of the shift element, wherein the flange is received by a stepped bore formed in the shifting device and from which the shift element extends through the shifting device in the direction of the other end of the shift element, and wherein the flange of the shift element is received with play by the stepped bore.
