Description

ProblemstellungProblem

Zweispurige Fahrräder besitzen meist Starrachsen mit Achsschenkel- oder Achsschemellenkung. Normalerweise ergibt sich durch Antrieb eines einzelnen Vorder oder Hinterrades eine dritte Spur. Radfederungen sind an solchen Fahrzeugen nicht üblich. Gelegentlich werden Sättel, selten auch das mittelspurige Einzelrad gefedert. Die außermittigen Räder können wie bei einem Kfz über Doppelquerlenker und Achsschenkel geführt werden. Die normale Abstützung der Feder/Dämpfer am Rahmen verhindert jedoch die bei Fahrrädern nötige Seitenneigung und ergibt Querkräfte auf die Räder, die die Kurvengeschwindigkeit reduzieren oder die Speichenräder zerstören.Two-track bicycles usually have rigid axles with steering knuckles or axle brackets. A third track is usually created by driving a single front or rear wheel. Wheel suspension is not common on such vehicles. Occasionally, saddles are sprung, and rarely the single wheel in the middle track is sprung. The off-center wheels can be guided via double wishbones and steering knuckles, as in a car. However, the normal support of the spring/damper on the frame prevents the lateral inclination required on bicycles and results in lateral forces on the wheels, which reduce the cornering speed or destroy the spoked wheels.

Erfindunginvention

Kombination der Doppelquerlenker mit einem hängenden Feder/Dämpferelement )s. Skizze 1-3):Combination of double wishbones with a hanging spring/damper element (see sketch 1-3):

An einem Rahmen mit den Längsrohren (A, B, C, D) befinden sich Lagerungen für die Querlenker (a, b, c, d) und das Pendel (P) als hängendes Feder/Dämpferelement. Es ist mit den oberen Querlenkern außen über die Zugstangen (Z) verbunden.On a frame with the longitudinal tubes (A, B, C, D) there are bearings for the wishbones (a, b, c, d) and the pendulum (P) as a hanging spring/damper element. It is connected to the upper wishbones on the outside via the tie rods (Z).

Das Pendel wird durch einen Gummizug (G) mit geringen Kräften in der Mitte am Rahmenrohr (C) gehalten, damit der Rahmen im Stand nicht zur Seite kippt. (In Fahrt wird das Fahrzeug wie ein Einspurfahrrad dynamisch stabilisiert.)The pendulum is held in the middle of the frame tube (C) by a rubber band (G) with low forces so that the frame does not tip to the side when stationary. (When moving, the vehicle is dynamically stabilized like a single-track bicycle.)

Auswirkungimpact

Durch das Pendel werden die Vertikalkräfte auf die beiden Räder gegenseitig vollkommen ausgeglichen. Durch die Neigemöglichkeit können wie beim Einspurfahrzeug Querkräfte auf die Räder eliminiert werden (s. Skizze 3).The pendulum completely balances out the vertical forces on the two wheels. The tilting option means that transverse forces on the wheels can be eliminated, as with a single-track vehicle (see sketch 3).

Mit einem solchen Fahrzeug wird mehr Komfort und Sicherheit erreicht als bisher mit Dreirädern u.a. Mehrspurfahrräder möglich. Solche Fahrzeuge erlauben auch Personen mit eingeschränktem Gleichgewichtssinn das Radfahren. Anfahren ist wegen stabiler Ausgangslage einfach, auch als Liegerad ist Anfahren leichter. Durch die Neigemöglichkeit gewährleisten schon geringe Spurbreiten ausreichende Stabilität.With such a vehicle, more comfort and safety is achieved than was previously possible with tricycles and multi-track bicycles. Such vehicles also allow people with a limited sense of balance to cycle. Starting off is easy due to the stable starting position, and starting off is also easier as a recumbent bike. Thanks to the tilting option, even small track widths ensure sufficient stability.

Ausführungexecution

Die Konstruktion ist bereits ausgeführt an einem kompakten Liegeradtandem als gelenkte Vorderachse. Die Skizzen sind maßstäblich für eine Spurweite von 800 mm und Radgröße 26".The design has already been implemented on a compact recumbent tandem as a steered front axle. The sketches are to scale for a track width of 800 mm and wheel size 26".

Claims (1)

Fahrwerklanding gear für zweispurige Fahrzeuge mit einfachem Belastungsausgleichfor two-track vehicles with simple load compensation SchutzansprücheProtection claims Anspruch 1 dadurch gekennzeichnet, Claim 1 is characterized in that daß an einem zweispurigen Fahrzeug mit Doppelquerlenkern die Feder/Dämpferelemente wie gewöhnlich außen an einem Querlenker, innen jedoch nicht am Rahmen, sondern an einem Pendel abgestützt sind. Das Pendel ist hängend, zentral angeordnet.that on a two-track vehicle with double wishbones, the spring/damper elements are supported on the outside as usual on a wishbone, but on the inside not on the frame, but on a pendulum. The pendulum is suspended, centrally arranged. Anspruch 2 dadurch gekennzeichnet, Claim 2 characterized in that daß das hängende, zentrale Pendel selbst als Feder/Dämpferelement ausgebildet ist und mit den oberen Querienkem außen neben den Achsschenkelbolzen über zwei Zugstreben verbunden wird. Die Belastung als Druckkraft der Querlenker auf den kugelig gelagerten Achsschenkelbolzen ist konstruktiv einfach aufzufangen.that the hanging, central pendulum itself is designed as a spring/damper element and is connected to the upper wishbones on the outside next to the steering knuckle pins via two tension struts. The load as a compressive force of the wishbones on the spherically mounted steering kingpins is structurally easy to absorb. Anspruch 3 dadurch gekennzeichnet, Claim 3 is characterized in that daß Stöße nicht direkt von den Zugstreben auf den Rahmen, sondern zuerst über das dämpfende Pendel auf die andere Seite übertragen und erst nach dem Ausgleich als Rest über die Feder in den Rahmen eingeleitet werden.that shocks are not transferred directly from the tension struts to the frame, but first via the damping pendulum to the other side and only after compensation are they introduced into the frame as a remainder via the spring.
