The invention relates to a mechanical non-return mechanism for an aircraft application, wherein the aircraft application can be part of a flight control. The non-return mechanism comprises at least one drag brake, at least one main brake, and at least one ball ramp mechanism.

A driving device for moving a tailgate of a vehicle, comprising a permanent magnet brake, which comprises a stationary portion, a first braking element, which is rotatable relative to the stationary portion about a rotational axis, and a second braking element, which is arranged in a rotationally fixed manner on the stationary portion, is axially offset from the first braking element along the rotational axis and cooperates with the first braking element in order to generate a braking force. The first braking element and/or the second braking element have a permanent magnet or are formed by a permanent magnet, a magnetic attraction force acts between the first braking element and the second braking element axially along the rotational axis. Axially between the first braking element and the second braking element is arranged a friction element, which is in frictional contact with the first braking element and the second braking element.

A multi-disk brake assembly includes a stator disk that is non-rotatable, a rotatable rotor disk arranged adjacently and coaxially with the stator disk, and an axial retention device. The rotor disk and the stator disk are axially moveable between an engaged position during braking operation and a disengaged position during a released mode of operation. The axial retention device is axially moveable and supports at least one of the disks. The axial retention device includes a set of axially translatable pins or bolts that are pushed by the disks during the braking operation and maintain a predetermined space between the disks during the released mode of operation. The predetermined space and position of the disks is maintained when the brake assembly is subject to forces due to vehicle acceleration or cornering.
