Description
Die Erfindung bezieht sich auf eine Teilbelagscheibenbremse mit einem die Bremsscheibe umgreifenden U-förmigen Schwimm- oder Schwenksattel, in dessen einem als Bremszylinder ausgebildeten Schenkel die von dem Bremskolben beaufschlagbare Bremsbacke geführt ist und die Führung dieser Bremsbacke sowie die Bremszylinderachse zum Erzielen einer sich selbstverstärkenden Bremswirkung in der normalen Drehrichtung der Bremsscheibe mit der Bremsscheibe einen spitzen Winkel bildet.The invention relates to a partially lined disc brake with a brake disc encompassing U-shaped floating or swiveling caliper, one of which is designed as a brake cylinder Leg which can be acted upon by the brake piston is guided and the guide of this Brake shoe and the brake cylinder axis to achieve a self-reinforcing braking effect forms an acute angle with the brake disc in the normal direction of rotation of the brake disc.
Es ist eine derartige Bremse vorgeschlagen worden, bei der jedoch der Bremssattel aus einem Stück ist. In diesem Fall ist das Gußstück für das Gehäuse schwer herzustellen und zu bearbeiten. Der Betäti-Such a brake has been proposed, but in which the brake caliper is made in one piece. In this case, the casting for the housing is difficult to manufacture and machine. The actuating

Bei Teilbelagscheibenbremsen ist es an sich bereits bekannt, den Bremssattel zweiteilig auszuführen.In the case of partially lined disc brakes, it is already known per se to design the brake caliper in two parts.
F i g. 2 zeigt die Bremse nach F i g. 1 in der Draufsicht. F i g. 2 shows the brake according to FIG. 1 in plan view.
Bei der in F i g. 1 und 2 gezeigten Bremse wird die direkt zu betätigende Bremsbacke 71 durch einen 5 Kolben 73 gegen die Bremsscheibe 72 gedrückt. Der Kolben arbeitet in einem hydraulischen Zylinder 74, dessen Achse unter einem geeigneten Winkel entgegen der normalen Drehrichtung der Bremsscheibe zur Bremsscheibe hin geneigt ist. Der Kolben wirkt ίο auf die Bremsbacke über ein schwenkbares Druckstück 75 und eine Stützplatte 76, dessen, in Drehrichtung der Scheibe gesehen, vorderes Ende sich parallel zur Zylinderachse erstreckt. Zwischen dem vorderen Ende der Stützplatte und einer dazu gungszylinder kann nicht in das Gehäuse mit ein- 15 parallelen Anlagefläche ist eine Rolle 77 angeordnet, bezogen werden, sondern muß als gesondertes Bau- welche die Reibung zwischen der Stützplatte 76 undIn the case of the in FIG. 1 and 2, the brake shoe 71, which is to be operated directly, is activated by a 5 piston 73 pressed against the brake disc 72. The piston works in a hydraulic cylinder 74, its axis at a suitable angle opposite to the normal direction of rotation of the brake disc is inclined towards the brake disc. The piston acts ίο on the brake shoe via a swiveling pressure piece 75 and a support plate 76, the front end of which, seen in the direction of rotation of the disk, is extends parallel to the cylinder axis. Between the front end of the support plate and one to it cylinder cannot be inserted into the housing with a 15 parallel contact surface, a roller 77 is arranged, be related, but must as a separate construction which reduces the friction between the support plate 76 and

The effort of the brake shoe 71 to follow the torsional stress for the connecting screws of the disc leads to the fact that the support results in the brake caliper parts. The screws can plate 76 to rest on the guide surface 78 therefore have a smaller diameter than is brought, which in turn brings a reaction force on the known split brake calipers, so that also by which the brake shoe 71 is pressed against the disk of the brake caliper as a whole will.

In contrast to the effect that is just as great as the one that has already been proposed, the production could be achieved with a brake operated on both sides, and the machining of the brake caliper is much easier, since the parts are much easier with regard to the guide, 60
as well as the cylinder bore and the parting line standing at right angles to it can be machined in one setting.
