Abstract: A magnetic clutch for actuating a disconnect clutch includes an axis of rotation, an axially fixed stator, an axially movable armature, a torque-axial force converter unit with an armature side and a bearing side, and a rotary brake. The axially movable armature is axially retainable on the stator by a magnetic force from a power supply. The torque-axial force converter unit acts in an antagonistic manner to the magnetic force to hold the armature at an axial distance from the stator. The rotary brake is for effecting a rotational speed difference between the armature side and the bearing side. Other aspects of the disclosure include a disconnect clutch for an internal combustion engine in a hybrid drive train, a hybrid drive train, and a method for controlled closing of the disconnect clutch.
