KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Vorrichtung zum Anziehen von Wagenbremsen, welche durch Flüssigkeitsdruck in Thätigkeit gesetzt werden.The invention relates to a device for applying car brakes, which by Fluid pressure can be put into action.
In zwei Cylindern A und B bewegen sich in dem Cylinder A der Kolben C mit dem kleinen Kolben K und in dem Cylinder B der gröfsere Kolben D. Beide Cylinder sind durch Gummimembranen m, durch 0 und.mittelst eines Deckelstückes s so geschlossen, dafs über der Membran ein Hohlraum F bleibt. Die beiden Hohlräume bei A und B sind mittelst Röhrchen mit einander bei i verbunden und ist dieser gut abgedichtete Raum mit Glycerin oder dergl. gefüllt.In two casts A and B of the piston C move in the cylinder A with the small piston in the cylinder and K B of the piston gröfsere D. Both cylinders are m by rubber membranes through 0 of a cover piece und.mittelst s closed so, that on a cavity F remains in the membrane. The two cavities at A and B are connected to each other by small tubes at i , and this well-sealed space is filled with glycerine or the like.
Die Welle E ist nun bei den Ruhepunkten der Kolben C und K so oval geformt, dafs . letztere bei einer Vierteldrehung bei η mittelst Hebel oder Spindel beide Kolben zugleich hebt und bei weiterer Drehung jedoch nur den kleineren Kolben K und damit eine grofse Pressung auf die Membran tn im Cylinder B und somit durch Uebertragung auf den Bremsklotz ausübt.The shaft E is now oval shaped at the rest points of the pistons C and K that. the latter with a quarter turn at η by means of a lever or spindle lifts both pistons at the same time and, with further rotation, however, only exerts the smaller piston K and thus a great pressure on the membrane tn in the cylinder B and thus by transferring it to the brake pad.
Beim Zurückdrehen der Welle E drückt die Feder G die Kolben in ihre frühere Lage zurück. When the shaft E rotates back, the spring G pushes the pistons back into their previous position.
Eine dritte Membran m η bei A mit dem Kolben ο dient in Verbindung mit den Schrauben ρ bei A und r bei L zur richtigen Stellung dieses Bremsapparates.A third membrane m η at A with the piston ο is used in conjunction with the screws ρ at A and r at L for the correct position of this braking device.
Die Anordnung der Bremsen -an den Wagen ist sehr verschieden und in ihrer gewöhnlichen Ausführung als Hand- oder Fufsbremse nach den Fig. 1 und 2 anzunehmen. Fig. 1 und 2 stellen eine Handbremse dar, A1 die offene und A2 die geschlossene Fufsbremse. Der Bremshebel verbleibt in jeder Stellung, und da er nur höchstens eine halbe Drehung macht und sich dabei zweierlei Geschwindigkeiten um Druckä'ufserungen ergeben, so ist diese Bremswirkung eine augenblickliche und doch auch energische, genau dem Leergange und der Druckwirkung der beiden Bremsklötze angepafst.The arrangement of the brakes on the car is very different and can be assumed in its usual design as a hand or foot brake according to FIGS. Fig. 1 and 2 show a handbrake, A 1 the open and A 2 the closed foot brake. The brake lever remains in every position, and since it only makes half a turn at most and there are two different speeds for pressure increases, this braking effect is an instantaneous and yet energetic, precisely adapted to the empty space and the pressure effect of the two brake pads.
