Der Gegenstand der Erfindung unterscheidet sich von der dem Patent 148313 zugrunde liegenden Reibungsbremse mit Bremskraftregler dadurch, daß für die beiden Kegel derThe subject matter of the invention differs from that of patent 148313 lying friction brake with brake force regulator in that for the two cones of the

. 5 Reibungskupplungen nur eine einzige, die gemeinschaftliche Seilwindetrommel tragende Muffe vorgesehen ist, gegen die die Kegel der Anstell- und der Reglerkupplung wirken. Fig. ι zeigt die Kupplung in einem Längsschnitt nach Linie A-B der Fig. 2,. 5 friction clutches only a single sleeve bearing the common cable winch drum is provided, against which the cones of the pitch and governor clutch act. Fig. Ι shows the coupling in a longitudinal section along line AB of Fig. 2,

Fig. 2 die Gesamtanordnung der Bremse.
Auf die Radachse ist die Kupplungsmuffe η lose aufgesetzt, deren innere Wandung zwei kegelförmige Reibungsflächen besitzt. Die Nabe dieser Muffe ist mit zwei Nuten ο und ρ versehen, von denen die eine ρ die Windetrommel bildet, auf welche das auf das Bremsgestänge wirkende Seil q aufgerollt wird, während die andere 0 eine zur Verschiebung der Rolle dienende Gabel/aufnimmt. Fig. 2 shows the overall arrangement of the brake.
The coupling sleeve η is loosely placed on the wheel axle, the inner wall of which has two conical friction surfaces. The hub of this sleeve is provided with two grooves ο and ρ , one of which ρ forms the winch drum on which the rope q acting on the brake linkage is rolled up, while the other 0 accommodates a fork / used to move the roller.

Die Kupplungsmuffe 3 der Fliehkraftkupplung bietet der einen Reibungsfläche der Rolle η eine kegelförmige Reibungsfläche 4 dar, welche mit der Muffe 3 mit Hilfe von zwei; Scheiben 15 aus gewelltem Stahlblech verbunden ist, die auf Ansätze 14 auf der Muffe 3 geschraubt sind. .Diese Gesamteinrichtung, welche in der Richtung ihres Durchmessers starr, parallel zur Radachse aber biegsam ist, gestattet der Muffe n, um den gewünschten Betrag vorzurücken, um mit dem Kegel 5 in Berührung zu treten. Die Federn 16, welche die mit den gewellten Blechen 15 und dem Boden der Kupplungsmuffe 3 verbundenen Bolzen umgeben, gestatten, das Zurückgehen des Kegels 4 zu mäßigen.The coupling sleeve 3 of the centrifugal clutch offers the one friction surface of the roller η a conical friction surface 4, which with the sleeve 3 with the help of two; Disks 15 made of corrugated sheet steel are connected, which are screwed onto lugs 14 on the sleeve 3. This overall device, which is rigid in the direction of its diameter but flexible parallel to the wheel axis, allows the sleeve n to advance the desired amount in order to come into contact with the cone 5. The springs 16 surrounding the pins connected to the corrugated sheets 15 and the bottom of the coupling sleeve 3 make it possible to moderate the retraction of the cone 4.

Die Kupplungsmuffe 3 umgibt die Zwischenrolle 7, an welcher mit Hilfe von BoI-zen'6 der Kegel 5 befestigt ist, der mit der zweiten Reibungsfläche der Muffe η zusammenwirkt. Die biegsame Hülle 8 schützt die Kupplung gegen Staub.The coupling sleeve 3 surrounds the intermediate roller 7, to which the cone 5 is fastened with the aid of BoI-zen'6, which cone interacts with the second friction surface of the sleeve η . The flexible sheath 8 protects the coupling against dust.

Der den Fliehkraftregler bildende Teil wird durch Massen 9 gebildet, welche zwischen Rippen der Muffe 3 untergebracht sind und welche unter der Wirkung der Fliehkraft auseinander gehen und gegen die innere Fläche der Rolle 7 das Stahlband 11 legen, das zur Sicherung des Mitnehmens der Zwischenrolle dient.The part forming the governor is formed by masses 9, which between Ribs of the sleeve 3 are housed and which apart under the action of centrifugal force go and put against the inner surface of the roller 7, the steel band 11, which for Securing the taking of the intermediate role is used.

Endlich legt sich die Rolle 7 mit Hilfe von Reibungsrollen 18 gegen den Bund 19, welcher auf der Nabe der Muffe 3 befestigt ist.Finally, the roller 7 lies against the collar 19 with the help of friction rollers 18, which is attached to the hub of the sleeve 3.

Zum Anstellen der Bremse kann beispielsweise die in Fig. 2 dargestellte Einrichtung angewendet werden.The device shown in FIG. 2, for example, can be used to apply the brake be applied.

chamber is vented, the rod c of the piston b advances outward and acts through the intermediary of the rod lock e on the engagement fork f, which is rotatable about the pin g, which is attached to the vehicle frame. The spring i makes it possible to moderate the effect of the brake piston on the clutch fork and consequently to make the ratio of the braked weight to the total weight of the vehicle variable. To adjust according to the load, the nut k is rotated until the pointer m is opposite the corresponding graduation of a degree. The release of the clutch is also secured by the spring i. The brake operates in the manner described in patent 148313. The . The pressure reduction in the front piston chamber causes the piston rod c to move outwards, and the fork f places the sleeve η against the coupling surfaces 4 and 5. For normal braking, only the cone 4 is engaged. The roll η is then taken along and winds the cord q, which acts on the brake linkage, onto the winch ρ until the tension of this cord is sufficient to cancel the entrainment force communicated to the cone 4. At this moment the role η will come to a standstill. If the pressure reduction is increased, the sleeve η is shifted even more to the right and the cone 5 is also engaged. The sleeve «is taken along again and an additional pull is exerted on the cord q, which increases the braking force without, however, causing the wheels to jam. Would a! If you want to set yourself, then, since the speed of the rotation of the wheel axle is reduced, - the entrainment of the roller 7, which is brought about by the masses 9 of the controller, would be weaker and as a result the cone 5 partially released again. If the speed of the wheel axle falls below a given limit, the braking is reduced to the value that is given by touching the cone 4, regardless of the pressure reduction caused by the driver. Patent-A ν Proverbs:

1. An embodiment of the friction brake with a braking force regulator dependent on the driving speed according to patent 148313, characterized in that the outer coupling bodies of the two friction clutches are combined into a single sleeve (s) carrying the common cable winch drum (ρ) , against which the cones (4 and 5) of the adjusting clutch and the governor clutch are effective.

2. An embodiment according to claim i, characterized in that the cone (4) of the adjusting coupling is connected to the sleeve (3) by flexible plates, which are flexible in the axial direction of the coupling and adjustable by means of spring bolts (16), in order to close the sleeve (n ) to be able to move further after engaging the cone (4) to engage the cone (5).
