Description
Fahrradfederung Es sind Fahrradfederungen verschiedenster Aus führungen bekannt, die sich jedoch in der Praxis im allgemeinen nicht durchsetzen konnten. Der Grund hierfür liegt darin, dass das Fahrrad durch Muskel kraft bewegt wird und beim Treten die Federung immer mitbewegt werden muss<B>;</B> sie arbeitet also während des Fahrens. Durch die Federung wird also das Fahren für den Fahrer anstrengender. Dies zeigt sich am meisten auf glatter Fahrbahn und ganz beson ders beim Befahren von Steigungen. In diesem Fall wird durch die Gewichtsverlagerung des menschli chen Körpers beim Abwärtstreten die Federung je- desmal betätigt und dies erfordert einen erheblichen zusätzlichen Kraftaufwand für den Fahrer.
Da die Leistungsreserve des menschlichen Körpers nur ge ring ist, so tritt dieser Nachteil beim Befahren star ker Steigungen besonders hemmend in Erscheinung. Dagegen besitzt jede Fahrradfederung beim Abwärts fahren Vorteile. Sie dämpft die auftretenden Stösse und die Muskelkraft wird nicht beansprucht. Beim Fahren auf schlechter Fahrbahn wird der Lauf des ungefederten Fahrrades stark abgebremst, da die Vorderradgabel unter einem Winkel von ca. <B>600</B> zur Fahrbahn steht. Die eine Stosskomponente wirkt der Fahrtrichtung entgegengesetzt; das ganze Gewicht des Fahrzeuges muss angehoben werden, wenn das Vorderrad z. B. in eine Vertiefung der Fahrbahn fällt.
Auf einer schlechten Fahrbahn tritt sich des halb ein gefedertes Rad leichter, da die Fahrbahn- stösse durch die Federung aufgenommen werden. Der Kraftverbrauch beim Treten ist dabei erheblich geringer als bei einem ungefederten Fahrzeug.
Erfindungsgemäss sollen die Nachteile der bishe rigen Fahrradfederungen dadurch beseitigt sein, dass die Federung aussehaltbar ist. Das Vorder- oder Hin terrad kann also auch vollkommen ungefedert laufen. Das Ausschalten der Federung kann erfolgen<B>-</B> <B>1)</B> Bei Teleskopfederungen z. B. durch Zusammen ziehung der geschlitzten Führungen, in denen die Gabelholme gleiten<B>;</B> 2) Bei Schwinghebelfederungen durch Festsetzen der Federbeine ähnlich wie bei der Teleskopfederung oder durch Blockieren des Drehpunktes der Schwinghebel; <B>3)</B> Bei Geradfederungen durch Zusammenziehen der geschlitzten Federführungen.
Die Ausschaltung der Federung kann so einge richtet sein, dass sie entweder im Stillstand des Fahr zeuges durch Hand oder Fuss erfolgen kann oder während der Fahrt durch Bowdenzug oder derglei chen. Beim Vorderrad kann es sich als zweckmässig erweisen, die Federung automatisch beim Bremsen ausschaltbar zu machen. Dabei kann bei der Vorder radbremse das Widerlager für den Bowdenzug an der Federung so angebracht sein, dass beim Anziehen der Bremse sich automatisch die geschlitzte Führung der Federung festsetzt.
Durch die Erfindung soll erreicht werden, dass der Radfahrer auf Strecken, bei denen seine Muskel kraft nicht benötigt wird, ein gefedertes Fahrrad hat, z. B. auf Gefällstrecken, während auf Strecken, die viel Muskelkraft von ihm erfordern, z. B. beim Berg fahren, die Federung ausgeschaltet ist, so dass das Fahrrad wie ein ungefedertes Fahrzeug zu treten ist. Die oben geschilderten Nachteile fallen deshalb bei dieser Federung weg.
Bicycle suspension There are bicycle suspensions of various types from known, but in general could not prevail in practice. The reason for this is that the bicycle is moved by muscle power and the suspension must always be moved when pedaling <B>; </B> it works while riding. The suspension makes driving more strenuous for the driver. This is most evident on slippery roads and especially when driving on inclines. In this case, the weight shift of the human body when stepping down actuates the suspension each time and this requires a considerable additional effort on the part of the driver.
Since the power reserve of the human body is only low, this disadvantage is particularly inhibiting when driving steep gradients. In contrast, every bicycle suspension has advantages when going downhill. It dampens the impacts that occur and the muscle strength is not used. When driving on a poor road surface, the unsprung bicycle is strongly braked because the front fork is at an angle of approx. <B> 600 </B> to the road. One impact component acts opposite to the direction of travel; the entire weight of the vehicle must be lifted when the front wheel z. B. falls into a depression in the roadway.
On a bad road surface, a sprung wheel treads more easily, since the road bumps are absorbed by the suspension. The power consumption when pedaling is significantly lower than with an unsprung vehicle.
According to the invention, the disadvantages of bishe ring bicycle suspensions are to be eliminated in that the suspension can be removed. The front or rear wheel can also run completely unsprung. The suspension can be switched off <B> - </B> <B> 1) </B> With telescopic suspension, e.g. B. by drawing together the slotted guides in which the fork legs slide <B>; </B> 2) In the case of rocker arm suspensions by fixing the struts similar to telescopic suspension or by blocking the pivot point of the rocker arm; <B> 3) </B> For straight springs by pulling together the slotted spring guides.
The suspension can be switched off in such a way that it can be done either by hand or foot when the vehicle is stationary or by a Bowden cable or the like while driving. In the case of the front wheel, it can be useful to automatically switch off the suspension when braking. With the front wheel brake, the abutment for the Bowden cable can be attached to the suspension so that when the brake is applied, the slotted guide of the suspension is automatically set.
The aim of the invention is to ensure that the cyclist has a sprung bike on routes where his muscle force is not required, e.g. B. on slopes, while on routes that require a lot of muscle strength from him, z. B. when driving uphill, the suspension is switched off so that the bike can be stepped like an unsprung vehicle. The disadvantages outlined above are therefore eliminated with this suspension.
