Abstract

The transmission contains a drive shaft, revolvable in a bearing to connect a toothed drive wheel to an internally or externally toothed take off wheel. The take off wheel is revolvably held on one side of a hollow crank. The crank in turn is held revolvable with its other side in a second bearing. To allow power transmission, a flexible shaft is contained in the crank, and centrally connected to the take-off wheel and the take off shaft. Both bearings are located along an optical axis. The crank is braked to obtain the highest gear ration.

Description

Betrifft : " Stufenlos selbsttätiges Setriebe für Kraftfahrzeuge " - Patentanmeldung, Josef W ο b s t , 6460 Selnhaus en , Untermarkt 10. Subject: "Stepless automatic transmission for motor vehicles" - patent application, Josef W ο bst, 6460 Selnhaus en, Untermarkt 10.

Der derzeitige technische Stand von Getrieben für Kraftfahrzeuge, ist durch die vielen 2iraftfahrer als fast schon allgemein bekannt zu bezeichnen. Das einfache von Hand mit Zwischengas zu schaltende, wurde vom synchronisierten abgelöst, es kamen die Getriebeautomaten, flüssigkeitsgetriebe usw.The current technical status of transmissions for motor vehicles is almost as good as it is due to the many 2iraftfahrer commonly known to designate. The simple manual double-declutching has been replaced by the synchronized one, there came the automatic gearboxes, fluid gears, etc.

Das im nachfolgenden beschriebene und in der Zeichnung dargestellte, stellt nach tfissen des Anmelders eine völlig neue hoglichkeit eines stufenlos selbsttätigen Getriebes dar, welches sich durch besonders einfachen Aufbau ausweist.The following described and shown in the drawing, represents a completely new one, according to the applicant's knowledge possibility of a continuously variable automatic transmission, which is characterized by a particularly simple structure.

Die einzelnen Bezugszeichen der Zeichnung bedeuten :The individual reference symbols in the drawing mean:

(1) Lager, (2) Antriebswelle, (3) Antriebszahnrad, (4) Abtriebszahnrad, (5) Hohlkurbel, (5a) Hohlkurbelseite, (5b) Hohlkurbelseite, (6) biegsame Welle, (7) Lager, (8) Abtriebswelle.(1) bearing, (2) drive shaft, (3) drive gear, (4) output gear, (5) hollow crank, (5a) hollow crank side, (5b) hollow crank side, (6) flexible shaft, (7) bearing, (8) output shaft.

Lager (1) und Lager (7) sind in optischer Achse angeordnet. Die in Lager (1) drehbar angeordnete Antriebswelle (2) ist fest verbunden mit Antriebszahnrad (3), dieses befindet sich im Eingriff mit Abtriebszahnrad (4) welches an die Hohlkurbel (5) bei Mohlkurbelseite (5a) drehbar gelagert ist. Die Hohlkurbel (5) ist mit Hohlkurbelseite (5b) drehbar gelagert in Lager (7) desgleichen die Abtriebswelle (8). Die biegsame tfelle (6) ist mit Mitte Abtriebszahnrad (4) und mit Mitte Abtriebswelle (8) fest verbunden.Bearing (1) and bearing (7) are arranged in the optical axis. The drive shaft (2) rotatably arranged in the bearing (1) is firmly connected to the drive gear (3), this is in engagement with the output gear (4) which is attached to the hollow crank (5) is rotatably mounted on the Mohl crank side (5a). The hollow crank (5) is rotatably mounted on the hollow crank side (5b) in the same way the output shaft (8) is in bearing (7). The flexible skin (6) is centered on the output gear (4) and firmly connected to the middle of the output shaft (8).

Wirkungsweise :Mode of action:

Bei einer beispielsweise]* gewählten Größe von Antriebszahnrad (3) zu Abtriebszahnrad (4) von 1 : 3, kann die zu überwindende Last höchstens das dreifache der Antriebskraft betragen.If, for example,] * is selected, the size of the drive gear is selected (3) to output gear (4) of 1: 3, the load to be overcome can be a maximum of three times the driving force be.

tfenn nun Antriebszahnrad (3) mit einer gegebenen Antriebskraft in das Abtriebszahnrad (4) in Pfeilrichtung eingreift, und an der Abtriebswelle (8) eine dreifache Last liegt, finden folgende Drehbewegungen statt :Now disengage the drive gear (3) with a given drive force engages in the output gear (4) in the direction of the arrow, and there is a threefold load on the output shaft (8), the following rotary movements take place:

- 2 5 0 9825/0492- 2 5 0 9825/0492

Die Zahnflanken des außenverzahnten Antriebszahnrades (3) werden gezwungen, sich an den Zahnflanken des innenverzahnten AbtriebsZahnrades (4) abzuwälzen, die so entstehende Drehbewegung, setzt sich über die biegsame Welle (6) auf die Abtriebswelle (8) fort.The tooth flanks of the externally toothed drive gear (3) are forced to contact the tooth flanks of the internally toothed To roll off the output gear (4), the resulting rotary movement, continues via the flexible shaft (6) to the output shaft (8).

Gleichzeitig aber bewirkt das Abtriebszahnrad (4) welches an Hohlkurbel (5) drehbar gelagert ist, durch Druck auf diese Lagerung in Drehrichtung, desgleichen der Verwindungsdruck der in Hohlkurbel (5) sich bildenden Schleife der biegsamen Welle (6), einen beständigen Druck auf die Hohlkurbel (5) in Drehrichtung, um die optische Achse zwischen Lager (1) und Lager (7) gedacht. Die Hohlkurbel (5) kann aber bei der herrschenden Last, dieser Bewegung nicht folgen, weil die vorhandene Antriebskraft zur vorhandenen Last 1 : 3 einem Zwanglauf folgen muß, der sich von Antriebswelle (2) auf Antriebszahnrad (3) und über Abtriebszahnrad (4) auf die biegsame Welle (6) an die Abtriebswelle (8) überträgt, wobei die Hohlkurbel (5) stillsteht.At the same time, however, the output gear (4) causes it is rotatably mounted on the hollow crank (5), by pressure on this mounting in the direction of rotation, likewise the torsional pressure the loop of the flexible shaft (6) forming in the hollow crank (5), a constant pressure on the hollow crank (5) in the direction of rotation, around the optical axis between bearing (1) and bearing (7). The hollow crank (5) can with the prevailing load, do not follow this movement because the existing driving force corresponds to the existing load 1: 3 must follow a forced running, which extends from the drive shaft (2) to the drive gear (3) and via the output gear (4) to the transfers the flexible shaft (6) to the output shaft (8), the hollow crank (5) standing still.

Bei kleiner werdender Last an der Abtriebswelle (8), folgt bewirkt durch den oben angeführten Druck von Abtriebszahnrad (4) und Verwindungsdruck der biegsamen Welle (6), die Hohlkurbel (5) jedem kleinsten Nachlassen der Last an der Abtriebswelle (8) durch kleineren oder größeren Umlauf um die optische Achse zwischen Lager (1) und Lager (7)» bis zum Gleichlauf von Antriebswelle (2) und Abtriebswelle (8), wenn die zu überwindende last gleich der vorhandenen Antriebskraft ist.As the load on the output shaft (8) decreases, this is caused by the above-mentioned pressure from the output gear (4) and torsional pressure of the flexible shaft (6), the hollow crank (5) every slightest slack in the load on the Output shaft (8) by smaller or larger rotation around the optical axis between bearing (1) and bearing (7) »up to Synchronization of drive shaft (2) and output shaft (8) if the load to be overcome is equal to the existing drive force is.

Bei gleichbleibenden Drehzahlen einer Antriebskraft, können so, unterschiedliche Lasten mit unterschiedlichen Drehzahlen, stufenlos selbsttätig bewegt werden, welche Eigenschaft besonders für den Antrieb von Kraftfahrzeugen gewünscht ist0 Statt des dargestellten innenverzahnten Abtriebszahnrades (4) kann sinngemäß ein außenverzahntes angeordnet werden0 Technisch möglich ist natürlich auch eine Hintereinander-Anordnung solcher Getriebe.With constant speeds of a driving force, different loads can be moved automatically and steplessly at different speeds, which property is particularly desired for the drive of motor vehicles 0 Instead of the internally toothed output gear (4) shown, an externally toothed one can be arranged accordingly 0 This is technically possible, of course also a series arrangement of such gears.
