Abstract:
Im Allgemeinen wird die Erfindung in der Planetenbauweise vorgeschlagen, wobei es aus zwei Stufenplanetengetrieben besteht. Ein Stufenplanetengetriebe wird als Basisgetriebe bezeichnet und besteht aus einem dreistufigen Planetengetriebe, der andere Stufenplanetengetriebe wird als Erweiterungsgetriebe bezeichnet und besteht aus einem zweistufigen Planetengetriebe. Die Kombination vom Basisgetriebe mit dem Erweiterungsgetriebe ermöglicht das Erreichen von 142 Vorwärtsgängen und 69 Rückwärtsgängen. Die besondere Charakteristik der Erfindung sind die Zähnezahlen und das Verhältnis der Zähnezahlen von Zahnrädern, sodass durch genau fünf Planetenradsätzen insgesamt 142 Vorwärtsgänge und 69 Rückwärtsgänge mit einem breiten Bereich der Gesamtübersetzung realisiert werden können. Im Basisgetriebe sind drei Sonnenräder vorhanden. Die Zähnezahlen dieser drei Sonnenräder sind unterschiedlich, sodass diese Sonnenräder mit„kleiner" Sonnenrad, "mittelgroßer" Sonnenrad und "großer" Sonnenrad bezeichnet werden. Die Differenz der Zähnezahlen zwischen dem kleinem Sonnenrad und dem mittelgroßem Sonnenrad ist gleich wie die Differenz der Zähnezahlen zwischen dem großem Sonnenrad und dem mittelgroßem Sonnenrad. Dementsprechend ist die Zähnezahl des mittelgroßen Sonnenrads das arithmetische Mittel zwischen den Zähnezahlen vom kleinen Sonnenrad und dem großem Sonnenrad. Die Zähnezahlen der Planetenradsätze des mittelgroßen Sonnenrads sind identisch wie die Zähnezahlen des mittelgroßen Sonnenrads. Die Zähnezahlen der Planetenradsätze des kleinen Sonnenrads sind identisch wie die Zähnezahlen des großen Sonnenrads. Die Zähnezahlen der Planetenradsätze des großen Sonnenrads sind identisch wie die Zähnezahlen des kleinen Sonnenrads. Das Erweiterungsgetriebe besteht aus zweistufigen Planetenradsätzen. Eines dieser zwei Planetenradsätzen hat die gleichen Verhältnisse der Zähnezahlen wie der Planetenradsatz des kleinen Sonnenrads vom Basisgetriebe. Die eingesetzte Schaltkupplungen können lastschaltende kraftschlüssige und/oder formschlüssige Schaltkupplungen. Das Getriebe besitzt mehrere Schaltkupplungen, sodass formschlüssige Schaltkupplungen in Bezug auf den Wirkungsgrad vorteilhafter sind und es sind auch mehrere Kombination von Schaltkupplungen möglich. Das Getriebe ist im dritten bis achte Ausführungsbeispiele mit formschlüssige Zahnschaltkupplungen vorgesehen, wobei die fünften Ausführungsbeispiel bis achte Ausführungsbeispiel mit Sägezahnschaltkupplungen vorgesehen sind. Der Gangwechsel erfolgt bei allen Ausführungsbeispielen unter Last und, ausgenommen Ausführungsbeispiel 1, ohne Kraftflussunterbrechung. Im ersten Ausführungsbeispiel kommt es zu einer kurzzeitigen Kraftflussunterbrechung.Das sechste Ausführungsbeispiel ist für eine Fahrrad-Hinterradnabe vorgesehen und besitzt 44 Gangstufen, die unter Last oder im Stand schaltbar ist. Im siebten Ausführungsbeispiel ist das Getriebe im Kurbelrad des Fahrrads eingebaut und besitzt 44 Gangstufen, die unter Last und im Stand schaltbar sind. Das achte Ausführungsbeispiel ist für ein Trethebel-Fahrrad ohne Antriebskette mit Trethebeln, mit 42 Gangstufen vorgesehen die unter Last und im Stand schaltbar sind. Die Ausführungsbeispiel fünf bis acht sind sequentielle Getriebe. Das Getriebe im Ausführungsbeispiel eins bis drei für motorisierte Fahrzeuge ist nicht sequentiell, d.h. vom Startgang aus kann der Zielgang beliebig gewählt werden, wobei bei den Ausführungsbeispielen zwei, drei ein maximaler Gangsprung von 19 Stufen möglich ist. Das Trethebel-Fahrrad besitzt zwei Trethebel, die unabhängig voneinander angetrieben werden können, sodass auch körperlich benachteiligte Personen das Trethebelrad fahren können, da der Fuß eine geradlinige Bewegung durchführt und keine kreisende Bewegungen wie bei herkömmlichen Fahrrädern.
Abstract:
Disclosed is a hands and feet operated folding bicycle which is easily convertible into a hand bike suitable to be used by persons who have serious handicap in the lower body. The steering of the bicycle is accomplished as a rider moves the center of his/her body toward a desired traveling course. Also, considering the folding of the hands and feet operated folding bicycle, if a saddle backrest is laid down forward, a pair of axles, which are installed foldably at opposite sides of a rear wheel frame housing, are pulled forward by axle drive rods coupled to axle drive rod end hooks of a saddle backrest frame, whereby a pair of rear wheels, which are coupled to knuckle arms at opposite ends of both the axles, are pulled and gathered forward to thereby complete the folding of the bicycle. In this case, since the knuckle arms are connected to a pair of tie rods, and in turn, the tie rods are connected to opposite sides of a steering bar by means of a pair of tie rod ends, the tie rods can serve to steer the bicycle on the basis of the tilt of the rider's body during traveling. Also, in the course of folding the bicycle, the tie rods can serve to allow the knuckle arms to be kept parallel to each other while facilitating the forward displacement of the knuckle arms. Thereby, the pair of rear wheels, which are rotatably coupled to outer sides of both the knuckle arms, respectively, can be displaced forward while being kept parallel to each other. Also, since a second fork for supporting a front wheel is connected to a rear wheel frame by means of foldable hinges, if the second fork is released by use of a second fork fixing handle having an eccentric cam, a front wheel mechanism can be folded downward. The second fork is also hingedly coupled, at a front end thereof, to a front end of a first fork that constitutes the front wheel mechanism along with the second fork. In turn, a first fork fixing bush, which is hingedly coupled to a control bush supporting bar coupling bracket, is inserted into the first fork in such a manner that it is movable to be secured at a desired position. With this configuration, if a first fork control bush fixing handle is released, the first fork can be folded.

Abstract:
The invention relates generally to a planetary construction that consists of two multi-stage planetary gear mechanisms. One multi-stage planetary gear mechanism is referred to as a basic gear mechanism and consists of a three-stage planetary gear mechanism, and the other multi-stage planetary gear mechanism is referred to as a supplementary gear mechanism and consists of a two-stage planetary gear mechanism. The combination of the basic gear mechanism and supplementary gear mechanism allows 142 forward gears and 69 reverse gears to be obtained. The invention is characterised in particular by the tooth counts and the tooth count ratio of the toothed gears, such that a total of 142 forward gears and 69 reverse gears can be implemented, with a broad overall transmission-ratio range, using exactly five planetary gear sets. The basic gear mechanism comprises three sun gears. Said three sun gears have different tooth counts and these sun gears are therefore named the "small" sun gear, "medium" sun gear and "large" sun gear. The difference in tooth counts between the small and the medium sun gears is the same as the difference in tooth counts between the large and the medium sun gears. Accordingly, the medium sun gear tooth count is the arithmetic median between the tooth counts of the small and the large sun gears. The tooth counts of the planetary gear sets of the medium sun gear are identical to the tooth counts of the medium sun gear. The tooth counts of the planetary gear sets of the small sun gear are identical to the tooth counts of the large sun gear. The tooth counts of the planetary gear sets of the large sun gear are identical to the tooth counts of the small sun gear. The supplementary gear mechanism consists of two-stage planetary gear sets. One of these two planetary gear sets has the same tooth count ratios as the planetary gear set of the small sun gear in said basic gear mechanism. The shift clutches that are used can be force-fitting and/or form-fitting power-shiftable shift clutches. The gear mechanism consists of a plurality of shift clutches and as a result, form-fitting shift clutches are more advantageous in terms of efficiency, with a plurality of combinations of shift clutches also being made possible. The gear mechanism in the third to eighth embodiments is provided with form-fitting toothed shift clutches, while the fifth to eighth embodiments are provided with saw-toothed shift clutches. The gear is changed on-load in all embodiments and, with the exception of embodiment one, without interruption to the power flow. In the first embodiment, there is a short-term interruption to the power flow. The sixth embodiment is provided for a bicycle rear wheel hub and comprises 44 gear stages that can be shifted on-load or when stationary. In the seventh embodiment, the gear mechanism is integrated into the crank wheel of the bicycle and has 44 gear stages that can be shifted on-load and when stationary. The eighth embodiment is for a drive chain-free pedal lever bicycle having pedal levers, provided with 42 gear stages that can be shifted on-load and when stationary. Embodiments five to eight are sequential gear mechanisms. The gear mechanism in embodiments one to three for motorised vehicles is non-sequential, i.e. any target gear can be selected starting from the starting gear, with a maximum possible gear step of 19 stages in embodiments two and three. The pedal-lever bicycle comprises two pedal levers that can be driven independently of one another such that people with physical disabilities can also ride it since the foot moves linearly as opposed to in the circular motions of conventional bicycles.
