Abstract

The motor vehicle braking system has thrusters brought to bear against brake blocks on the wheels, and connected to each other by pipes. The thrusters are closed bellows (4), connected to a hydraulic system (3) ending in a pressure unit (2) actuated by a brake pedal (1) or lever. Both bellows and unit can be of variable volume, the unit being a bellows also, and all forming a closed pressure chamber. The bellows can each comprise a set of rings sliding in each other and together forming an impermeable wall. Inside each bellows there can be a sheet of material close to the wall, and forming a sealed internal cladding.

Description

Vorrichtung zum Bremsen von Fahrzeugen Device for braking vehicles

Die Erfindung betrifft eine Vortichtung zum Bremsen von Fahrzeugen init gegen Reiborgane der Fahrzeug-Räder, insbesondere gegen Bremsbacken oder Bremsscheiben, fahrbare sowie durch ein Leitungssystem verbundene Druckglieder Bekannte Bremsen dieser Art sind mit Kolben in Bremszylindern ausgestattet. Die Kolben werden durch die hydraulische Flüssigkeit während des Bremsvorganges innerhalb des Bremszylinders verschoben und wirken so auf die Bremsbacken oder Bremsschoiben. Als nachteilig hat sich gerade bei dieser Bauart erwiesen, daß Bremszylinder einerseits und Bremskolben andererseits nie so dicht aneinander gleiten können, daß nicht Bremeflüssigkeit austreten würde. Gerade bei Kraftfahrzeugen aber genügt bereits ein geringer Bremsflüssigekitsverlust, die Sicherheit des Fahrzeuges erheblich herabzusetzen Um derartige Nachteile zu beseitigen, sollen erfindungsgemäß Bremsvorrichtungen der eingangs erwähnten Art geschlossene Druckglieder in Form von Balgen aufweisen, welche an ein Flüssigkeitsdruksystem angeschlossen sind, das andernends in einem von einem Bremspedal zu betätigenden Hauptbalg endet.The invention relates to a device for braking vehicles init against friction elements of the vehicle wheels, in particular against brake shoes or brake disks, mobile pressure members connected by a system of pipes. Known brakes of this type are equipped with pistons in brake cylinders. The pistons are through the hydraulic fluid within the brake cylinder during the braking process shifted and thus act on the brake shoes or brake discs. As disadvantageous it has been shown with this type of construction that the brake cylinder on the one hand and the brake piston on the other hand, can never slide so close to each other that not brake fluid would emerge. In the case of motor vehicles, however, even a small loss of brake fluid kit is sufficient. considerably reduce the safety of the vehicle To such To eliminate disadvantages, according to the invention, braking devices of the initially mentioned mentioned type have closed pressure members in the form of bellows, which at a fluid pressure system are connected, the other end in one of one Brake pedal to be operated main bellows ends.

Hauptbalg und/oder Radbalge sind volumenveränderlich ausgebildet, so daß es nun möglich ist, exakt wirkende Bremsvorgänge durchzuführen, bei welchen Bremsflüssigkeit aus dem geschlossenen System gar nicht austreten kann.Main bellows and / or wheel bellows are designed to be variable in volume, so that it is now possible to carry out exactly acting braking processes in which Brake fluid cannot escape from the closed system at all.

Im Rahmen der Erfindung liegen Balge aus ineinandergreifenden und gegeneinander verschieblichen Werkstoffringen od. dgl., welche niteinander eine flüssigkeitsdichte Wandung bilden.In the context of the invention, bellows are made of interlocking and against each other displaceable material rings od. Like. Which nit each other a Form liquid-tight wall.

Nach weiteren Merkmalen der Erfidnung können innerhalb dieses Balg zusätzlich zumindest eine Hüllfolie od. dgl. und/oder Kraftspeicher untergebracht sein; der Druckwiderstand der Kraftspeicher vermag den jeweiligen Verhältnissen angepaßt zu werden.According to further features of the invention, this bellows In addition, at least one wrapping film or the like and / or energy storage is housed be; the pressure resistance of the energy accumulator is capable of the respective conditions to be adjusted.

Als besonders günstig hat sich erwiesen, daß der Hauptbalg mit einem durch das Bremspedal bewegbaren Bolzen versehen und dieser wöhrend des Bremsvorganges gegen ein Widerlager od.It has proven to be particularly favorable that the main bellows with a provided by the brake pedal movable bolt and this during the braking process against an abutment od.
