Abstract
Radantriebsdifferential, bestehend aus einer mit einem Welligkeitsprofil versehenen Mitnehmerscheibe, die federnd in das entsprechende Gegenprofil des nicht direkt angetriebenen Nebenantriebsrades des Fahrzeuges eingedrückt wird und dieses dann unterstützend mit antreiben kann, derart, dass beim Auftreten von Zwangskräften zwischen den Antriebsrädern bei Kurvenfahrten die Mitnehmerscheibe aus der Raststellung auswandern und dadurch eine unterschiedliche Räderdrehung ermöglichen kann, dadurch gekennzeichnet, dass die Mitnehmerscheibe einen feder-elastischen Einpannrand aufweist und die Gestalt des Welligkeitsprofil auf der Mitnehmerscheibe und des Rades durch – bildlich gesehen – eine Schneide erzeugt wird, die in radiale Richtung weisend sich zentrisch und völlig oder annähernd sinusförmig auf und ab über die Planfläche oder eine Konusfläche der zu gestaltenden Mitnehmerscheibe bzw. des Rades bewegt.Wheel drive differential, consisting of a drive plate provided with a ripple profile, which is pressed resiliently into the corresponding counter profile of the non-directly driven power take-off wheel of the vehicle and can then support it, in such a way that when constraining forces occur between the drive wheels when cornering, the drive plate comes out of the Emigrate to the rest position and thereby enable a different wheel rotation, characterized in that the drive plate has a spring-elastic clamping edge and the shape of the wavy profile on the drive plate and the wheel is generated - figuratively speaking - by a cutting edge that points centrically in the radial direction and moved completely or approximately sinusoidally up and down over the flat surface or a conical surface of the drive plate or the wheel to be designed.
Description
Speziell für Kindertret- und Kleinfahrzeuge ist es wünschenswert, wenn beim Befahren von wenig griffigen Fahrbahnböden, wie Rasen- und Sandwegen, neben dem Hauptantriebsrad ein Nebenantriebsrad ein zusätzliches, wenn auch geringeres Vortriebs-Moment als das Hauptantriebsrad, auf die Fahrbahn übertragen kann.It is especially for children's pedal and small vehicles it is desirable if when driving on non-slip road surfaces, such as lawn and sand paths, in addition to the main drive wheel, a secondary drive wheel an additional, although less propulsion torque than the main drive wheel, transferred to the road can.
Bei zwei auf einer Antriebswelle weit voneinander drehfest angebrachten Rädern, würden bei Kurvenfahrten durch die unterschiedliche Länge der zu durchfahrenden Strecken für das jeweilige Rad, erhebliche Zwangskräfte an den Räder auftreten, die das Fahr- und Lenkvermögen des Kleinfahrzeuges erheblich beeinträchtigen.With two on one drive shaft wheels that are fixed in a rotationally fixed manner from one another would pass through when cornering the different length of the routes to be traveled for the respective wheel, considerable constraining forces occur on the wheels, which the driving and steering ability of the small vehicle significantly affect.
Ein Differentialgetriebe, wie es üblicher Weise bei Kraftfahrzeugen Verwendung findet, ist jedoch für Kindertretfahrzeuge aus Kostengründen nicht einsetzbar.A differential gear, as is more common Way used in motor vehicles, however, is for children's pedal vehicles for cost reasons Not insertable.
Auch das dem Patentbegehren am ehesten entgegenstehende US Patent 1.477.310 – mit einem angetriebenen, sehr stabilen Getriebekasten mit 2 Paar wellenprofilartig ausgeführten und mit mehreren starken Spannfedern verpressten, massiven Kupplungsblöcken- ist aus Kostengründen und im Trockenlauf für ein Kinderfahrzeug nicht geeignet.Also the one most likely to oppose the patent application US Patent 1,477,310 - with a driven, very stable gear box with 2 pairs of wave profile executed and with several strong tension springs, massive coupling blocks for cost reasons and run dry for a child's vehicle is not suitable.
Der Erfindung liegt die Aufgabe zugrunde ein Differential zu schaffen, das aus Kostengründen einfach gestaltet ist.The invention is based on the object to create a differential that is simple for cost reasons.
Die Differentialwirkung bei Kurvenfahrten wird
dadurch erreicht, dass eine von der Radwelle angetriebene, mit einem
Wellenprofil versehene Scheibe (
Um ein genügend hohes Mitnahmemoment ohne
allzu große
Anpresskraft zu erzielen, sollte die Mitnehmerscheibe im Bereich
des Zentrums eine sehr hohe Flankensteigung des ausgerundeten Profiles
aufweisen (Bezugszeichen
Die elastische Vorspannung der Scheibe
gegenüber
dem Rad wird zur Reduzierung der Gestehungskosten an Stelle einer
Spannfeder auf der Antriebswelle durch einen federelastisch ausgeführten Einspannrand
