Die Zeichnung zeigt ein Anwendungsbeispiel der Erfindung bei einer Bremse mit Schwenkbügel. Die Erfindung betrifft jedoch ebenso Bremsen mit feststehendem Bügel und andere Scheibenbremsen. Das Radi mit Bereifung2 und ein die Bremsscheibe4 tragender Flansch 3 sind bei 5 mit einer Nabe 6 verschraubt, die auf einer feststehenden Achse 7 umläuft. Auf der Achse 7 ist mit Schrauben 8 eine Platte 9 befestigt, welche die Bremseinrichtung oder -einrichtungen trägt. Die Platte 9 ist mit Achsen 11 versehen, auf denen die Bremsbelagträger 12 gleiten, die durch Doppelfedern 13 auseinandergedrückt werden. Ferner trägt die Platte 9 einen Zapfen 15, um den ein Bremsenbügel 16 schwenkt. zoThe drawing shows an application example of the invention in a brake with a swivel bracket. the However, the invention also relates to fixed bracket brakes and other disc brakes. That Radiator with tires2 and a brake disc4 bearing flange 3 are screwed at 5 to a hub 6 which rotates on a fixed axis 7. On the axis 7 a plate 9 is attached with screws 8, which the braking device or -Bears facilities. The plate 9 is provided with axles 11 on which the brake lining carriers 12 slide, which are pushed apart by double springs 13. Furthermore, the plate 9 carries a pin 15 to a brake bracket 16 pivots. zo
Die Bremsbetätigungseinrichtung weist eine Mutter 20 mit Kugeln 21 und einer Kugelgangspindel 22 auf. Die Mutter 20 ist im Bremsenbügel 16 durch einen Schraubflansch 23 und einen Stift 24 festgelegt. Die Kugelgangspindel 22 enthält einen Stellteil as 25, der durch einen Keil 26 in der Kugelgangspindel 22 verschiebbar, aber nicht drehbar ist.The brake actuation device has a nut 20 with balls 21 and a ball screw 22 on. The nut 20 is fixed in the brake bracket 16 by a screw flange 23 and a pin 24. The ball screw 22 contains an adjusting part as 25, which is secured by a wedge 26 in the ball screw 22 is slidable, but not rotatable.
Der Stellteil 25 betätigt über eine Druckplatte 27 einen der Bremsbelagträger 12, wobei der Gegendruck durch den Bremsenbügel 16 auf den gegenüberliegenden Bremsbelagträger 12 übertragen wird. Der Stellteil 25 ist auf einen Schraubteil 28 aufgeschraubt, der mit einer auf der Kugelgangspindel 22 aufliegenden Schulter 29 versehen ist.The actuating part 25 actuates one of the brake lining carriers 12 via a pressure plate 27, with the counterpressure is transmitted through the brake bracket 16 to the opposite brake lining carrier 12. The actuating part 25 is screwed onto a screw part 28 which is connected to a screw on the ball screw 22 resting shoulder 29 is provided.
Eine einen Reibstein 40 aufweisende Reibeinrichtung ist in den Schraubteil 28 eingelassen und wird z. B. durch eine Blattfeder 41 oder entsprechende andere Mittel gegen den Stellteil 25 gedrückt. Mit Bakelitschichtstoff oder harzgebundenem oder kunststoffgebundenem Gewebe als Werkstoff für den Reibstein 40 wurden befriedigende Ergebnisse erzielt. Der Schraubteil 28 ist mit einer Feder 42 versehen, deren eines Ende 43 zwischen zwei Anschlägen 44 und 45 schwenkbar ist, welche Anschläge von einer durch Schrauben 47 am Bremsenbügel 16 befestigten Lasche 46 getragen werden. Die Kugelgangspindel 22 wird durch einen mit ihr durch einen Schraubflansch 51 und einen Keil 52 verblockten Hebel 50 betätigt, der mit einer Pfanne 53 versehen ist, in deren öffnung 54 das in einer Perle 56 endende Kabel 55 des Seilzugs 57 verschiebbar ist. Die Zwinge 58 der Hülle des Seilzugs 57 ist auf einem Fortsatz 59 des Bremsenbügels 16 befestigt. Eine als Druckfeder ausgebildete Rückstellfeder 60 ist zwischen dem Fortsatz 59 des Bremsenbügels 16 und der Pfanne 53 des Hebels 50 vorgesehen. Der Hebel 50 weist einen Nocken 66 auf, gegen den der Kolben 61 eines Antriebszylinders 62 drückt, welch letzterer von einer bei 47 am Bügel 16 befestigten Lasche 63 getragen wird.A friction device having a friction stone 40 is let into the screw part 28 and is z. B. is pressed against the actuating part 25 by a leaf spring 41 or other corresponding means. With bakelite laminate or resin-bonded or plastic-bonded fabric as the material for the friction stone 40, satisfactory results have been achieved. The screw part 28 is provided with a spring 42, one end 43 of which is between two stops 44 and 45 is pivotable, which stops are attached to the brake bracket 16 by screws 47 Tab 46 can be worn. The ball screw 22 is by one with her by one Screw flange 51 and a wedge 52 locked lever 50 actuated, which is provided with a pan 53 is, in the opening 54 of which the cable 55 of the cable 57, which ends in a bead 56, can be displaced. the Clamp 58 of the casing of the cable 57 is attached to an extension 59 of the brake bracket 16. One as Compression spring formed return spring 60 is between the extension 59 of the brake bracket 16 and the pan 53 of the lever 50 is provided. The lever 50 has a cam 66 against which the piston 61 of a drive cylinder 62 presses the latter from a tab 63 attached at 47 to bracket 16 will be carried.
Durch seine Befestigungsweise mit den Schrauben 47 ist der Antriebszylinder 62 schnell ausbaubar, wodurch einerseits die Wartung erleichtert und es andererseits ermöglicht wird, daß entsprechend den jeweiligen Erfordernissen bei ein und derselben Bremse ohne Änderung wesentlicher Teile Antriebszylinder verschiedener Größen verwendbar sind.Due to the way it is fastened with the screws 47, the drive cylinder 62 can be removed quickly, as a result of which on the one hand the maintenance and on the other hand it is made possible that according to the respective Requirements for one and the same brake without changing essential parts of the drive cylinder different sizes can be used.
