A friction brake assembly includes a brake housing; an input coupling element; an output coupling element; and a torsion spring. The input coupling element has an axial protrusion forming a partial cylinder wall with an angular gap over a defined angular range. The output coupling element has a projection protruding into the at least one angular gap, wherein the projection has an angular width smaller than the angular gap; wherein the torsion spring is a coil spring with coil ends forming two radially inward pins protruding into the angular gap in the input coupling element between the partial cylinder wall and the projection so that the projection is between the two inward pins. The torsion spring has a diameter that expands to form a friction lock with a surrounding cylindrical wall when the projection of the output coupling element engages and moves either one of the inward pins.

Friction brake and power strut therewith

A spindle drive assembly includes a threaded spindle rotatable about a spindle axis; a threaded spindle nut disposed on the threaded spindle and configured to travel along the spindle axis via a rotation of the spindle; a ball stud attached to the spindle nut, the ball stud extending radially away from the spindle nut; an attachment plate configured to be attached to a part to be moved; and a ball socket connected to the attachment plate and having a cavity dimensioned for receiving the ball stud. The cavity of the ball socket has a first diameter in a direction perpendicular to the spindle axis and a second diameter parallel to the spindle axis, wherein the first diameter is greater than the second diameter.
