Description
Der als dreirädriges Fahrzeug mit Fußantrieb ausgebildete Tretwagen bezweckt, die schon beim Fahrrad gegebenen Sport-, Touren- und Erholungsmöglichkeiten zu verbessern. Der in Abb. i in Seitenansicht, in Abb.2 in Draufsicht schematisch dargestellte Tretwagen läuft auf drei Rädern, vorn zwei lenkbare Räder und hinten ein Triebrad.The pedal car designed as a three-wheeled vehicle with foot drive aims to provide the sport, touring and recreational opportunities that are already available on bicycles to improve. The one in Fig. I in side view, in Fig. 2 in top view schematically The pedal car shown runs on three wheels, two steerable wheels at the front and two at the rear a driving wheel.
Steuerung: Beide Vorderräder sind gefaßt in Gabeln, deren innerer Schenkel als Achsschenkel drehbar befestigt ist, und durch Lenkhebel verbunden mit der Spurstange, welche mit einem Steuerrad über doppelte Drahtseile betätigt wird.Control: Both front wheels are held in forks, the inner one Leg is rotatably attached as a stub axle, and connected by steering levers the tie rod, which is operated with a steering wheel via double wire ropes.
Antrieb: Dreimal gelagerte Tretwelle für die beiden Fahrer mit vier Pedalen an Tretkurbeln, die jeweils um 9o Grad zueinander versetzt sind, so daß beim Treten kein Totpunkt entsteht; die beiden Fahrer sitzen nebeneinander, und die Tretwelle liegt in derselben Ebene oder höher als die Sitzflächen. Ein aufgesetztes Kettenrad überträgt die Kraft auf das Hinterrad, welches dieselbe über eine mehrfache Kettenumschaltung aufnimmt.Drive: pedal shaft with three bearings for the two riders with four Pedals on cranks, which are offset from each other by 9o degrees, so that there is no dead center when pedaling; the two drivers sit next to each other, and the pedal shaft is on the same level or higher than the seat surfaces. A fake one Sprocket transmits the power to the rear wheel, which the same over a multiple Chain switching picks up.
Bremsen: Es sind zwei voneinander unabhängige Bremsen vorhanden, deren eine auf das Hinterrad, die andere über einen Bremsausgleich auf beide Vorderräder wirkt.Brakes: There are two independent brakes one on the rear wheel, the other via brake compensation on both front wheels works.
Sitze: Zwischen zwei Rahmenrohre sind wie bei einem Liegestuhl zwei Gurte eingespannt, welche ein halb liegendes, die Bewegung nicht behinderndes Sitzen erlauben. Die Sitze liegen nebeneinander.Seats: Between two frame tubes, like a deck chair, there are two Belts clamped in, which means a semi-recumbent sitting that does not impede movement allow. The seats are next to each other.
Die Vorteile des Tretwagens gegenüber dem Fahrrad bestehen darin, daß i. der Tretwagen als Fahrzeug mit bequemen Sitzen ein weniger ermüdendes Fahren gestattet, bei gleichzeitig geringerer Bodenreibung drei Räder statt vier aufweist, da zum Vergleich für zwei Personen zwei Fahrräder angesetzt werden müssen, und geringeres Gewicht besitzt, nämlich 27 kg gegenüber 34 kg von zwei Fahrrädern; 2. daß durch die Versetzung der Tretkurbeln jeweils um 9o Grad gegeneinander in der Tretbewegung kein Totpunkt auftreten kann, was besonders beim Bergfahren vorteilhaft in Erscheinung tritt.The advantages of the pedal car over the bicycle are: that i. the pedal car as a vehicle with comfortable seats means less tiring driving allowed to have three wheels instead of four with lower ground friction at the same time, since two bicycles have to be used for comparison for two people, and less Owns weight, namely 27 kg versus 34 kg for two bicycles; 2. that through the offset of the cranks each by 9o degrees against each other in the pedaling movement no dead center can occur, which is particularly advantageous when driving uphill occurs.
Andere Kleinigkeiten, wie günstigere Luftwiderstandsverhältnisse, Gepäckraum, Schutz gegen Regen, bieten weitere Vorteile.Other little things, such as more favorable air resistance ratios, Luggage space and protection against rain offer further advantages.
