Device for braking bicycles The invention relates to a Device for braking bicycles with retracting against the wheel while charging Energy storage feasible brake shoes, which by at least one brake handle to are actuated.

Uebliche Fahrradbremsvorrichtungen weisen einen an der Lenkstange des Fahrrades angebrachten Betätigungshandhebel auf sowie im Bereich der Räder angebrachte Bremsbacken sowie diese Teile miteinander verbindende Bowdenzüge.Usual bicycle brake devices have one on the handlebar of the bicycle mounted operating hand lever on and in the area of the wheels Brake shoes and Bowden cables connecting these parts.

Bei Kraftfahrzeugen sind hydraulische Bremsanlagen bekannt, von denen bisher stets angenommen wurde, daß sie für Fahrräder im Hinblick auf die Kosten und den komplizierten Aufbau ungeeignet sind.In motor vehicles, hydraulic brake systems are known, of which Heretofore it has always been assumed that they are suitable for bicycles in terms of cost and the complicated structure are unsuitable.

Der Erfinder hat sich mit vorliegendem Problem befaßt und die Aufgabe übernommen, eine neuartige Bremseinrichtung für Fahrräder der eingangs erwähnten Art zu schaffen, welche sich die Vorzüge der bekannten Automobilbremsanlagen zunutze macht.The inventor has dealt with the present problem and the task taken over, a novel braking device for bicycles of the aforementioned Art to create which takes advantage of the well-known automobile brake systems power.

Zur Lösung dieser Aufgabe führt der Gedanke, daß an den Bremsbacken hydraulisch bewegbare Druckglieder angreifen und diese an ein Flüssigkeitsdrucksystem angeschlossen sind, das andernends in einem vom Bremsgriff zu betätigenden Hydrauliksystem endet.To solve this problem, the idea that on the brake shoes leads attack hydraulically movable pressure members and these to a fluid pressure system are connected, the other end in a hydraulic system to be operated by the brake lever ends.

Bei einem Ausführungsbeispiel soll der Hydraulikzylinder bevorzugtermaßen mit einem durch den Bremsgriff bewegbaren Kolben versehen und dieser während des Bremsvorganges gegen das Leitungssystem führbar sein, an dessen Ende wenigstens ein weiterer von einem Hydraulikzylinder umgebener Kolben vorgesehen ist.In one embodiment, the hydraulic cylinder is intended to be preferred provided with a movable piston by the brake lever and this during the Braking process against the line system be feasible, at least at the end another piston surrounded by a hydraulic cylinder is provided.

Als besonders günstig hat es sich erwiesen, den Hydraulikzylinder und/oder die Radbremszylinder selbst volumenveränderlich auszubilden.The hydraulic cylinder has proven to be particularly favorable and / or to design the wheel brake cylinders themselves to be variable in volume.

Dank dieser Vorrichtung ist es nun möglich, exakt wirkende Bremsvorgänge ohne die von mechanischen Bremsen bekannten Störungen durchzuführen. Die erfindungsgemäße Bremsanlage ist kostengünstig herzustellen, leicht zu warten und auch nachträglich an jede Art von Fahrrad - mit oder ohne Hilfsmotor - anzubringen.Thanks to this device, it is now possible to perform braking processes that work exactly without performing the malfunctions known from mechanical brakes. The inventive Brake system is inexpensive to manufacture, easy to maintain and can also be retrofitted to be attached to any type of bicycle - with or without an auxiliary motor.

Erfindungsgemäß sollen die Hydraulikzylinder als Balgglieder ausgebildet sein, bevorzugt mit ineinandergreifenden und gegeneinander verschieblichen Werkstoffringen, welche miteinander eine flüssigkeitsdichte Wandung bilden. Diese Ausführungsform hat gegenüber der vorabgeschriebenen den zusätzlichen Vorteil, keine Flüssigkeitsverluste im Bereich der Einheitkolben-Zylinder zu haben. Es handelt sich also um ein völlig geschlossenes Drucksystem ohne Leckage.According to the invention, the hydraulic cylinders should be designed as bellows members preferably with interlocking and mutually displaceable material rings, which together form a liquid-tight wall. This embodiment has the additional advantage over the above-mentioned that there is no loss of fluid in the area of the standard piston-cylinder. So it is a completely closed pressure system without leakage.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in: Fig. l: die schematisierte Draufsicht auf eine Bremsanlage; Fig. 2: eine teilweise geschnittene Seitenansicht einer Bremsanlage an einer übersichtlichkeitshalber etwa horizontal gelegten Radgabel; Fig. 3: ein Detail aus Fig. 2, geschnitten etwa gemäß Linie III in Fig. 2.Further advantages, features and details of the invention result can be derived from the following description of preferred exemplary embodiments and based on the drawing; this shows in: FIG. 1: the schematic plan view of a brake system; FIG. 2: a partially sectioned side view of a brake system for the sake of clarity approximately horizontally placed wheel fork; Fig. 3: a detail from Fig. 2, cut approximately according to line III in FIG. 2.

Beidseits der Felge F eines nur mit einem Rad E angedeuteten Fahrrades sind zwei Bremsbacken 1 mit felgenwärtigen Bremsklötzen 2 aus Gummi oder dgl. angeordnet.On both sides of the rim F of a bicycle only indicated with one wheel E. are two brake shoes 1 with rim-facing brake pads 2 made of rubber or the like. Arranged.

Die Bremsbacken 1 werden von je zwei um Bolzen 3 gelegte Rückholfedern 4 in ihrer in Fig. 1 erkennbaren Ruhelage gehalten. Die Rückholfedern 4 sind in einem Halteklotz 5 gelagert, dessen seitlicher Tragarm 6 fest in einer seitlichen Lasche 7 des Lenkergestelles 8 sitzt. Gegen die Innenseite 9 der Bremsbacke 1 drückt zwischen den Bolzen 3 ein Bremskolben 10, der in Fig. 1 in einem Hydraulikzylinder 11 untergebracht ist.The brake shoes 1 are each supported by two return springs placed around bolts 3 4 held in their rest position recognizable in FIG. 1. The return springs 4 are in a holding block 5 mounted, the lateral support arm 6 fixed in a lateral Tab 7 of the handlebar frame 8 is seated. Presses against the inside 9 of the brake shoe 1 between the bolts 3 a brake piston 10, which in Fig. 1 in a hydraulic cylinder 11 is housed.

Die Hydraulikorgane 10 bzw. 11 sind über Flüssigkeitsleitungen 12 mit einem T-Verbinder 13 und über diesen sowie einen gemeinsamen Schlauch 14 mit dem am Lenkgriff 15 in einem Bremsengehäuse 16 angebrachten Hauptbremszylinders 17 verbunden.The hydraulic organs 10 and 11 are connected via fluid lines 12 with a T-connector 13 and over this and a common hose 14 with the master brake cylinder attached to the steering handle 15 in a brake housing 16 17 connected.
