Abstract: A power strut for raising and lowering a liftgate of an automotive vehicle includes an outer housing tube carrying a first attachment element for attaching the power strut to a vehicle. A spindle bearing an outer thread is rotatable relative to the outer housing tube via an electric motor. The spindle is axially stationary relative to the outer housing tube. A spindle nut having an inner thread meshing with the outer thread of the spindle is displaceable along the longitudinal axis. A nut tube is rigidly connected to the spindle nut and surrounds the spindle. A second attachment element is located opposite the first attachment element. The first attachment element has a first snap structure that is complementary to a second snap structure formed on the outer housing tube. The first and second snap structures non-rotatably secure the first attachment element to the outer housing tube.

Abstract: A power strut assembly for raising and lowering a panel of an automotive vehicle includes a strut housing defining two parallel axes, i.e. a motor rotary axis and a spindle rotary axis. A drive motor disposed in the strut housing has an output shaft rotatable by the drive motor about the motor rotary axis. A drive spindle with a threaded section at least partially disposed in the strut housing is rotatable about the spindle rotary axis to move a spindle nut on the threaded section of the drive spindle. A motor-spindle transmission for transmitting a rotation of the output shaft to the drive spindle includes a motor wheel secured to the output shaft and a spindle wheel rigidly coupled to the drive spindle. The motor wheel and the spindle wheel extend in a common plane of rotation.

Abstract: 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.

Abstract: 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.
