Abstract
Description
Stand der TechnikState of technology
Die Erfindung geht aus von einer Drehfeder nach dem Oberbegriff des Anspruchs 1.The invention is based on one Torsion spring according to the preamble of claim 1.
Eine solche Drehfeder findet verschiedenartige Anwendung, so z.B. als Rückstellfeder in Drosselvorrichtungen für Brennkraftmaschinen in Kraftfahrzeugen. Drosselvorrichtungen werden z.B. im Ansaugrohr der Brennkraftmaschine angeordnet, um die Luftmenge zur Aufbereitung eines Kraftstoff-Luft-Gemisches zu steuern. Darüber hinaus finden sie auch Einsatz bei Brennkraftmaschinen mit Abgasrückführung und dienen hier zur Abgasdosierung bei der Gemischaufbereitung.Such a torsion spring is of various types Application, e.g. as a return spring in throttling devices for Internal combustion engines in motor vehicles. Throttle devices are e.g. arranged in the intake pipe of the internal combustion engine to the amount of air to control the preparation of a fuel-air mixture. Furthermore they are also used in internal combustion engines with exhaust gas recirculation and serve here for exhaust gas metering in mixture preparation.
Bei einer bekannten Drosselvorrichtung
(
Die erfindungsgemäße Drehfeder mit den Merkmalen des Anspruchs 1 hat den Vorteil, daß sie auf einem glatten, durchgehend zylindrischen Führungsdorn gut geführt werden kann, den Führungsdorn praktisch nur mit den eingezogenen Windungsenden berührt und dadurch Reibung und Hysterese der Drehfeder minimiert sind. Dadurch, daß die erste und letzte Federwindung fest auf dem Führungsdorn aufliegen kann die Drehfeder seitlich nicht ausbrechen und arbeitet auch im gespannten Zustand annähernd zylindrisch. Somit ist kein Platzbedarf um die Feder herum erforderlich, so daß die erfindungsgemäße Drehfeder weniger Einbauraum benötigt.The torsion spring according to the invention with the features of claim 1 has the advantage that it is on a smooth, continuous cylindrical guide mandrel well run can be the guide pin touched practically only with the retracted winding ends and friction and hysteresis of the torsion spring are minimized. Thereby, that the the first and last spring turn can rest firmly on the guide mandrel Torsion spring does not break out to the side and also works in tensioned Approximate condition cylindrical. So no space is required around the spring, So that the Torsion spring according to the invention less installation space required.
Die erfindungsgemäße Drehfeder kann sowohl rechts- als auch linksgewickelt ausgeführt werden.The torsion spring according to the invention can be as well as left-handed become.
Die erfindungsgemäße Drehfeder wird bevorzugt in einer Drosselvorrichtung im Luftansaug- oder Abgasrückführweg einer Brennkraftmaschine eingesetzt. Diese Drosselvorrichtung weist in bekannter Weise eine eine von einem Drosselgehäuse umschlossene Drosselöffnung steuernde Drosselklappe, die auf einer Schwenkwelle drehfest sitzt, und ein mit der Schwenkwelle fest verbundenes antreibbares Drehglied auf. Die erfindungsgemäße Drehfeder ist mit Radialspiel auf einen zur Schwenkwelle konzentrischen, zylindrischen Führungsdorn aufgenommen, wobei das eine Federende am Drehglied und das andere Federende am Drosselgehäuse festgelegt ist. Die Reduktion des Windungsradiusses in einem Windungsabschnitt an den Federenden ist so vorgenommen, daß der minimale Windungsradius dem Außenradius des Führungsdorns entspricht. Vorzugsweise ist der Führungsdorn axial geteilt, und die Feder ist mit ihrem eingezogenen Windungsabschnitt an dem einen Federende auf dem einen Teildorn und mit ihrem eingezogenen Windungsabschnitt an dem anderen Federende auf dem anderen Teildorn geführt. Der eine Teildorn ist mit dem Drehglied vorzugsweise einstückig verbunden und der andere Teildorn an dem Drosselgehäuse angeformt. Bei dieser Drosselvorrichtung lassen sich die Vorteile der erfindungsgemäßen Drehfeder, nämlich gute Führung auf einem zylindrischen Führungsdorn mit durchgängig konstantem Außendurchmesser, Einsparung von radialem Bauraum durch ausschließlich zylindrisches Arbeiten der Drehfeder und geringe Reibung, Verschleiß und Federhysterese durch die Festlegung nur der ersten und letzten Windung auf dem Führungsdorn, voll ausschöpfen.The torsion spring according to the invention is preferred in a throttle device in the air intake or exhaust gas recirculation path Internal combustion engine used. This throttle device has in known manner controlling a throttle opening enclosed by a throttle housing Throttle valve, which sits on a swivel shaft, and a with the swivel shaft firmly connected drivable rotary member. The torsion spring according to the invention is with radial play on a cylindrical concentric to the swivel shaft Guide mandrel added, one end of the spring on the rotating member and the other end of the spring on Throttle body set is. The reduction of the turn radius in a turn section is made at the spring ends so that the minimum turn radius outer radius of the guide pin equivalent. Preferably, the guide mandrel is axially divided, and the Spring is at one with its retracted winding section Spring end on one partial mandrel and with its retracted winding section guided at the other end of the spring on the other partial mandrel. The a partial mandrel is preferably connected in one piece to the rotary member and the other partial mandrel is formed on the throttle housing. With this throttle device the advantages of the torsion spring according to the invention, namely good guidance a cylindrical guide pin with consistent constant outside diameter, Saving of radial installation space through exclusively cylindrical work the torsion spring and low friction, wear and spring hysteresis the definition of only the first and last turn on the guide mandrel, make full use of.
