Abstract
Dreirad mit 2 Fronträdern gekennzeichnet dadurch, daß gemäßeine Vorderradeinheit ( 6 ) über ihre auf den Aufstandspunkt des Hinterrades ausgerichtete Drehlagerung ( 3 ) mit dem Lenkerrohr ( 4 ) sowie über einen Stützträger ( 7 )und ein Kugelgelenk ( 8 ) mit dem Fahrradrahmen ( 9 ) verbunden ist.Tricycle with 2 front wheels characterized in that according to a front wheel unit (6) via its aligned to the Aufstandsspunkt the rear wheel pivot bearing (3) with the handlebar tube (4) and a support bracket (7) and a ball joint (8) with the bicycle frame (9) connected is.
Description
Neben den verbreiteten einspurigen,zweirädrigen Fahrrädern und Motorrädern sind zweispurige Dreiräder bekannt ,deren Einsatz in kleineren Marktsegmenten erfolgt, wie Lastenräder , sog. Trikes und Räder für Nutzer, denen eine Kontrolle einspuriger Fahrzeuge nicht möglich oder zu unsicher ist.In addition to the widespread single-track, two-wheeled bicycles and motorcycles two-lane tricycles are known to be used in smaller market segments, such as cargo bikes, so-called trikes and wheels for users who control single-track vehicles is not possible or too uncertain.
Durch die Alterung der Gesellschaft wird auch die Gruppe der Radfahrer mit Beeinträchtigung des Gleichgewichtssinns größer. Viele ältere Radfahrer haben vor allem beim Auf- und Absteigen sowie bei langsamer Fahrt Probleme mit der Kontrolle, wogegen bei normaler Fahrt keine oder wenig Unsicherheit besteht.Due to the aging of the society, the group of cyclists with impaired sense of balance becomes larger. Many older cyclists have problems with the control, especially when getting on and off as well as driving slowly, whereas there is little or no uncertainty during normal driving.
Ein Verzicht dieser Gruppe auf das Radfahren bedeutet oft Bewegungsmangel und Verlust an Lebensfreude.A renunciation of this group on cycling often means lack of exercise and loss of vitality.
Der Umstieg auf ein erheblich schwereres und sperriges Dreirad ist neben der psychischen Hürde auch dadurch erschwert, dass die Fahrdynamik eines Dreirades eine völlig andere ist ,als die gewohnte eines herkömmlichen,einspurigen Fahrrades und daß das Fahren neu erlernt werden muss.The change to a considerably heavier and bulky tricycle is complicated by the fact that the driving dynamics of a tricycle is a completely different than the usual of a conventional, single-track bike and that driving must be re-learned in addition to the psychological hurdle.
Ziel der Erfindung ist ein Fahrzeug, welches dem Fahrverhalten eines herkömmlichen Zweirades entspricht und das eine sichere Nutzung in allen Fahrsituationen auch für Fahrer mit den o. g. Beeinträchtigungen ermöglicht. Dabei sollen Abmessungen und Gewicht eines Zweirades möglichst wenig vergrößert werden.The aim of the invention is a vehicle that corresponds to the driving behavior of a conventional two-wheeler and the safe use in all driving situations for drivers with the o. G. Impairments. The dimensions and weight of a bicycle should be increased as little as possible.
Erfindungsgemäß wird dies durch ein Dreirad realisiert, welches beim Auf- und Absteigen , Anfahren und Bremsen bis zum Stand die Kippsicherheit eines Dreirades besitzt und bei Streckenfahrt über die vertraute Fahrdynamik eines normalen einspurigen Fahrzeuges verfügt.According to the invention, this is realized by a tricycle, which has the tilting safety of a tricycle when getting on and off, starting and braking up to the stand and has the familiar driving dynamics of a normal single-lane vehicle when driving on the road.
In einer bevorzugten Ausführung für ein dreirädriges Fahrrad gern
Im vorderen Bereich sind 2 Vorderräder (
Der Radträger (
Im Dreiradmodus ist gemäß
Erreicht wird dies dadurch, dass der Drehpunkt des Kugelgelenks (
Die Umschaltung zwischen beiden Betriebsarten erfolgt über eine Bedieneinheit am Lenker, z. B. über einen mit einem Handbremsgriff vergleichbaren Handhebel.The switchover between the two operating modes via an operating unit on the handlebar, z. B. via a comparable with a handbrake handle lever.
Dazu ist zwischen Stützträger (
Die Gleitführung (
Typischerweise erfolgt das Schieben des Fahrrades im Zweiradmodus, das Aufsteigen und Anfahren im Dreiradmodus und die Streckenfahrt im Zweiradmodus . Beim Bremsen wird kurz vor dem Stillstand auf Dreiradmodus umgeschaltet und danach abgestiegen oder wieder angefahren. Durch die Wählbarkeit der Blockierposition kann auch auf schrägem Untergrund der Dreiradbetrieb bei vertikaler Rahmenstellung eingeschaltet werden.Typically, pushing the bicycle in two-wheeler mode, getting on and off in tricycle mode, and riding in two-wheeler mode. When braking is switched shortly before the standstill on tricycle mode and then descended or started again. Due to the selectability of the blocking position, tricycle operation can also be activated on a sloping ground when the frame position is vertical.
Alternativ kann eine automatische Umschaltung über eine Fahrgeschwindigkeitssignal ( Tachometer oder Dynamospannung ) vorgesehen werden.Alternatively, an automatic change over a vehicle speed signal (speedometer or dynamo voltage) can be provided.
Alternativ kann eine abgestufte Bremsung des Gleitschlittens (
Alternativ kann der Gleitschlitten (
Alle genannten Verfahren sind auch bei Pedelecs und Motorrädern anwendbar.All these procedures are also applicable to pedelecs and motorcycles.
