Abstract:
PROBLEM TO BE SOLVED: To provide a gear unit of a simpler design, which can be manufactured cost-effectively. SOLUTION: The invention is a gear unit and a motor driven gear unit for a lifting system of a vehicle cable window, cooperates with a drive (14, 50 ; 59, 60), winds up a cable (53) of the cable window lifting system (100) and is provided with gear mechanisms (15, 10) which is combined with a cable drum (17) rotatably mounted for feeding. In the invention, a diameter of the cable drum (17) for the gear unit or the motor driven gear unit is within a range of about 22 mm to about 30 mm, more preferably within a range of about 24 mm to about 28 mm while a gear ratio of the gear mechanisms (15, 10) is within a range of about 1:38 to about 1:55, more preferably within a range of about 1:42 to about 1:51.

Abstract:
A drive unit for adjusting window panes, sunroofs, and seats in a vehicle has a reversible electric motor behind which is inserted a worm gear with a worm shaft. To prevent an undesired or unauthorized adjustment of a motor vehicle part, a brake device is provided. The brake device has a mechanical, one-way brake element with which the worm shaft may be coupled by an axial displacement. In order to reduce the effect of the brake device on the worm shaft when the window pane is adjusted by the electric motor, the brake element is the rotatable part of a rotation limiting device and, in the axial direction, it is supported on a stop.
Abstract:
Die Erfindung betrifft ein Schiebeteil mit wenigstens einer in dessen Verschieberichtung orientierter Führung und mit zumindest einer Feder, gegen deren Kraft das Schiebeteil über wenigstens einen Teil seines Schiebeweges verschiebbar ist, so dass zumindest ein Teil der entgegengesetzten Verschiebung durch Federkraft unterstützt oder durchführbar ist, dadurch gekennzeichnet, dass die zumindest eine Feder Teil wenigstens eines Federzugs mit einer sie enthaltenden, drehbar gelagerten Seiltrommel mit einem davon gegen die Kraft der Feder abwickelbaren Zugelement oder Seil ist, wobei ein Gehäuse des wenigstens einen Federzugs an dem Schiebeteil und das Ende des Zugelements oder des Seils in Schieberichtung dazu beabstandet im Bereich der Führung oder das Gehäuse des Federzugs im Bereich der Führung und das Ende des Zugelements oder des Seils an dem Schiebeteil direkt oder indirekt befestigt sind.
Abstract:
The invention relates to a drive device for a displaceable component, comprising a first fastening element, which can be connected to a stationary first component, and second component, which can be displaced axially relative thereto on the end opposite the first fastening element and which has a second fastening element, which can be fastened to the displaceable component at its end opposite the first fastening element. The device also comprises a spindle drive, which has a threaded spindle (3) and a spindle nut arranged on the threaded spindle (3) and which can displaceably drive the first component and the second component axially relative to one another. The spindle drive can be reversibly rotatably driven around an axis of rotation (6) by a drive shaft that can be rotatably driven by a rotary drive arranged non-rotatably in a housing, the axis of rotation extending coaxially towards the threaded spindle (3), the device further comprising a braking device which can prevent the first and second components from moving axially relative to each other by applying axial force to the first and/or second component.
Abstract:
An alternator isolating decoupler comprising an alternator shaft (100), a one-way clutch (70) engaged with the alternator shaft, a first wrap spring (40) releasably engaged with the one-way clutch, a second wrap spring (50) releasably engaged with the one-way clutch, the second wrap spring arranged in parallel with the first wrap spring, the first wrap spring and the second wrap spring in nested relation, the first wrap spring and the second wrap spring each having an end (41,51) releasably engagable with an end cap (90), the end cap fixedly connected to an outer housing (10), the first wrap spring and the second wrap spring each engaged in series with a torsion spring (20), the torsion spring engaged with the outer housing, and the outer housing engaged with an alternator rotor (110).
Abstract:
Die Erfindung betrifft eine Antriebsvorrichtung (1.1-1.4) aus einer Antriebseinheit (2,8) und einer Abtriebseineinheit (6,9), die beide mittels einer doppelseitig wirkenden Rutschkupplung (1,2) verbindbar sind, wobei die in beiden Drehrichtungen wirkenden Freigabemomente wählbar sind, insbesondere für den Antrieb einer Wickelwelle eines Rollladens, einer Markise, einer Jalousie oder dergleichen, vorzugsweise bei Dachfenstern. Um Falscheinwirkungen auf die Wickelwelle zu vermeiden, die beispielsweise bei schrägen Dachfenstern beim Öffnen und Schließen des Dachfensters entstehen, ist die Rutschkupplung (1,2) für jede Drehrichtung mit mindestens einer als Schleppfeder arbeitenden Schraubenfeder (3-5) ausgebildet, deren Freigabemoment derart bemessen ist, dass ein Falscheinwirkungen verhinderndes Auslösemoment erzeugt wird.
Abstract:
A brake-equipped retracting device (3) returns a liquid crystal display device (1) from a deployed position (1B) to a stored position (1A) using an elastic returning force of a spiral spring (18) that is wound up when the liquid crystal display device (1) is opened by the rotational force of a motor. A braking force for preventing the liquid crystal display device (1) from returning with too much force is applied to an input shaft (17a) of a reducer by having a rope (21) whose tensile force increases and decreases in relation to the opening and closing of the liquid crystal display device (1) be wound around a slip clutch (15) that is connected to the input shaft (17a). In emergency situations such as when the rope (21) breaks, a centrifugal grip (53) of a rotation-restraining mechanism (50) strikes an engagement notch surface (56b) on a fixed side, and the rotation of the input shaft (17a) is forcibly halted. A retracting device for a liquid crystal display device comprising a braking device that has a simple structure, is reliable, is highly safe, and is low in cost can be realized.
