Abstract:
The invention relates to a motor-driven device for actuating a movable panel (1) of a motor vehicle, including: a drive unit (3); a transmission element (5) which is to be set into motion by the motor unit (3); a braking module (7) for the transmission element (5), characterized in that the braking module (7) is connected to the transmission element (5) by a clutch module (9) positioned between the transmission element (5) and the drive unit (3), and comprising a wound spring (35) in friction contact with a brake shaft (23) connected to the braking module (7), as well as two coupling elements (25, 27) that are mutually engaged with a functional clearance therebetween, the relative change in position of said two coupling elements (25, 27) enabling the ends (37, 38) of said wound spring (35) to be controlled so as to switch the ends between an engaged position and a disengaged position of the braking module (7), wherein the two coupling elements (25, 27) are a drive element and a driven element, respectively.
Abstract:
A piece of furniture including a body and at least one flap that can be upwardly displaced by means of at least one actuating arm which is joined to the flap in an articulated manner and can preferably be pivoted about a horizontal axis. At least one actuating arm is subjected to the action of a spring device, and at least one electric drive acts on at least one actuating arm. A coupling device acts between the electric drive and the actuating arm, said coupling device having a free wheel for freely displacing the actuating arm into an open position and/or a closed position, in at least one rotary direction over a defined angular region.
Abstract:
The invention relates to a bidirectional drive for rotating in the one or the other direction of drive a drive wheel which is linked with an adjusting device. The bidirectional drive includes a drive lever which can be rotated about a drive axis, starting from an initial position, in the one or the other direction. The lever is linked with a coupling element for expanding a spring element that is at least partially supported by the cylindrical drive surface of the drive wheel and that entrains the drive wheel in the peripheral direction when the drive lever is moved away from the initial position, while the spring element is no longer supported by the cylindrical drive surface of the drive wheel and the drive wheel is not entrained when the drive lever is returned to the initial position. The coupling element includes expansion cams that can be tilted about an axis spaced apart from the drive axis. The expansion cams expand the actuation lever which is linked with the spring element in such a manner that the spring element which is supported by the cylindrical drive surface of the drive wheel is expanded.
Abstract:
Provided is a buried type hinge apparatus having an automatic return function in which a closing force of a door is provided with only a torsion spring. The hinge apparatus includes: a single body which is buried in a door; a shaft whose one end is projected through the upper cap and is rotatably supported; a piston which is slidably installed in the single body; a rotational/rectilinear motion conversion unit which converts a rotational motion of the shaft into an axial rectilinear motion of the piston according to opening and closing of the door; a damping unit that controls a descent and ascent speed of the piston, and provides a damping function selectively when the piston rises up; and a return unit that provides a restoring force for the rotational/rectilinear motion conversion unit so that the door is returned to an initial position of the door at the time of closing the door.
Abstract:
PROBLEM TO BE SOLVED: To provide a spring clutch of an improved durability which lessens an impact in torque transmission and inhibits loss due to breakage resulting from fatigue of a clutch spring. SOLUTION: In the spring clutch, the clutch spring 8 made of a wire rod of a square section is fit between a pulley 1 and a pulley hub 3. The clutch spring 8 is formed of a large-diameter helical torsion spring 8a, an arcuately reversed connection part 8b which is inwardly bent 180° at the end of the winding, a small-diameter helical torsion spring 8c which is in connection with the arcuately reversed connection part 8b. The large-diameter helical torsion spring and the small-diameter helical torsion spring are wound in the direction reverse to each other. The outside perimeter of the large-diameter helical torsion spring is elastically brought into contact with a clutch face 6 of the inside perimeter of the pulley. In the pulley hub, a clutch face 7 is formed opposite the small-diameter helical torsion spring. The unidirectional rotation of the pulley causes the large-diameter helical torsion spring to be brought into contact with the clutch face 6 to have the diameter enlarged, and rotated together with the pulley. In this case, the rotation is transmitted to the small-diameter helical torsion spring to gradually clamp the small-diameter helical torsion spring, as a result the pulley rotation is transmitted to the pulley hub.

Abstract:
A decoupler assembly for transferring rotary movement between an engine driven shaft and a serpentine belt. The decoupler includes a hub configured to be assembled to the shaft. The hub has a helical first slot formed therein. A pulley is rotatably coupled to the hub. A carrier is mounted on the hub and includes a helical second slot formed therein, as well as an anti-ramp up boss formed thereon. A thrust plate is fixed to the hub and has a slot formed therein. A torsion spring is compressed between a hub end retained in the helical first slot and a carrier end retained in the helical second slot for transferring torque between the hub and carrier. The anti-ramp up boss travels within the slot formed in the thrust plate for limiting rotation between the carrier and thrust plate and preventing rotation of the torsion spring relative to the hub and carrier.

Die Erfindung bezieht sich auf eine Antriebseinrichtung für ein bewegbares Bauteil, mit einem mit einem feststehenden ersten Bauelement verbindbaren ersten Befestigungselement und mit einem an dem dem ersten Befestigungselement entgegengesetzten Ende axial relativ dazu bewegbaren zweiten Bauelement, das an seinem dem ersten Befestigungselement entgegengesetzten Ende ein mit dem bewegbaren Bauteil befestigbares zweites Befestigungselement aufweist. Mit einem eine Gewindespindel (3) und eine auf der Gewindespindel (3) angeordneten Spindelmutter aufweisenden Spindeltrieb, durch den das erste Bauelement und das zweite Bauelement axial relativ zueinander bewegbar antreibbar sind. Dabei ist der Spindeltrieb von einer von einem drehfest in einem Gehäuse angeordneten Drehantrieb drehbar antreibbaren Antriebswelle reversierbar um eine Drehachse (6) drehbar antreibbar, die sich koaxial zur Gewindespindel (3) erstreckt und mit einer Bremseinrichtung, durch die ein axial relatives Zueinanderbewegen des ersten und zweiten Bauelements durch eine axiale Kraftbeaufschlagung des ersten und/oder zweiten Bauelements blockierbar ist.
