Abstract:
1. A clutch arrangement for a motor vehicle transmission, for connecting a shaft to a rotational element which is mounted thereon, wherein the clutch arrangement comprises: a sliding sleeve which is connected in a rotationally fixed fashion to the shaft and is mounted in an axially displaceable fashion on the shaft between a closed position and an open position and has a first sliding toothing; a clutch element which is connected in a rotationally fixed fashion to the rotational element and has a second sliding toothing into which the first sliding toothing can be inserted axially in the closing direction in order to connect the rotational element to the shaft in the closed position; and an actuator arrangement for axially sliding the sliding sleeve; wherein the actuator arrangement has an electromagnet arrangement which can be actuated in order to slide the sliding sleeve axially, wherein the electromagnet arrangement has a permanent magnet arrangement and a magnet housing which are arranged in such a way that with a magnetizable armature section of the sliding sleeve in at least one of the closed and open position they can form a magnetic circuit by means of which the sliding sleeve is held axially, wherein the magnet housing and the permanent magnet arrangement are fixed to a housing of the motor vehicle transmission.
