Description

Selbstverstärkend wirkende,. hydraulisch oder mechanisch betätigte Teilbelagscheibenbremse, insbesondere für Fahrzeuge Die Erfindung bezieht sich auf eine selbstverstärkend wirkende, hydraulisch oder mechanisch betätigte Teilbelagscheibenbremse, insbesondere für Fahrzeuge, mit einem die Bremsscheibe umgreifenden U-förmigen Bremssattel, der auf dem Bremsträger um einen mit Abstand von der Bremsscheibe angeordneten Bolzen schwenk-bar gelagert ist, dessen Achse auf der Bremsscheibe steht, wobei die zu beiden Seiten der Bremsscheibe an den Schenkeln des Bremssattels befestigten Bremsbacken, in Umfangsrichtung der Bremsscheibe gesehen, nebeneinander liegen, und stellt eine weitere Ausgestaltung des Gegenstands des Patents 1203 061 dar. #it Es ist eine Betätigungsvorrichtung für Fahrzeugbremsen mit einem feststehenden zylindrischen Gehäuse und mit zwei hydraulisch betätigbaren, gegenläufig arbeitenden Kolben bekannt, bei der die Kolben am Bremsträger schwenkbar gelagerte zweiarmige Bremshebel bewegen, wobei jeweils am freien Hebelarm ein Reibkörper befestigt ist. Die Reibkörper weisen keilförmigen Trapezquerschnitt auf und werden bei der Bremsbetätigung in eine entsprechende, in den äußeren Umfang der Bremsscheibe eingearbeitete Ringnut hineingepreßt.Self-reinforcing. hydraulically or mechanically operated partially lined disc brake, in particular for vehicles The invention relates to a self-energizing, hydraulically or mechanically actuated partially lined disc brake, in particular for vehicles, with a U-shaped brake caliper encompassing the brake disc, which is arranged on the brake carrier at a distance from the brake disc Bolt is pivotably mounted, the axis of which is on the brake disc, with the brake shoes attached to the legs of the brake caliper on both sides of the brake disc, viewed in the circumferential direction of the brake disc, lying next to one another, and represents a further embodiment of the subject matter of patent 1203 061 . #it There is an actuating device for vehicle brakes with a fixed cylindrical housing and two hydraulically actuated, counter-rotating pistons known, in which the pistons move pivotably mounted two-armed brake levers on the brake carrier, each on f A friction body is attached to the free lever arm. The friction bodies have a wedge-shaped trapezoidal cross-section and are pressed into a corresponding annular groove machined into the outer circumference of the brake disc when the brake is actuated.

Bekannt sind auch Teilbelagscheibenbremsen mit einer zweiten, unabhängig arbeitenden Bremsvorrichtung, wobei die mechanisch betätigte Vorrichtung ,entweder auf die der Bremsseheibe abgekehrte Stirnfläche des Betätigungskolbens einwirkt und sich auf dem Radzylindergehäuse abstützt oder aber als zusätzliche Vorrichtung in dem die Bremsscheibe umgreifenden Bremssattel neben der hydraulischen Betätigungsvorrichtung angeordnet ist.Partly lined disc brakes with a second, independent one are also known working braking device, the mechanically operated device, either acts on the end face of the actuating piston facing away from the brake disk and is supported on the wheel cylinder housing or as an additional device in the brake caliper encompassing the brake disc next to the hydraulic actuation device is arranged.

Diese bekannten Bremsen sind jedoch als Radbremsen ausgebildet und erfordern einen relativ großen radialen und axialen Platzbedarf und sind relativ aufwendig.However, these known brakes are designed as wheel brakes and require a relatively large radial and axial space and are relative laborious.

Aufgabe der vorliegenden Erfindung ist es, an einer selbstverstärkend wirkenden Teilbelagscheibenbremse nach dem Patent 1203 061 eine zweite unabhängige Bremsbetätigungsvorrichtung anzuordnen, die bei geringstem Platzbedarf außerordentlich einfach im Aufbau ist.The object of the present invention is to arrange a second independent brake actuation device on a self-energizing partially lined disc brake according to patent 1203 061 , which is extremely simple in construction with the smallest space requirement.

Erfindungsgemäß wird dies erreicht durch eine am Bremsträger angeordnete zweite unabhängige Bremsbetätigungsvorrichtung, die in an sich bekannter Weise aus einem zweiarmigen Hebel besteht, an dessen einem Ende die Betätigungskraft angreift und an dessen anderem Ende eine im Querschnitt V-förmige, mit den Reibflächen einer entsprechenden, in den äußeren Umfang der Bremsseheibe eingearbeiteten Ringnut in Reibungsschluß tretende Bremsbacke befestigt ist.According to the invention this is achieved by a arranged on the brake carrier second independent brake actuation device, which is made in a manner known per se consists of a two-armed lever, at one end of which the actuating force acts and at the other end a cross-sectionally V-shaped, with the friction surfaces a corresponding annular groove machined into the outer circumference of the brake disc Frictional stepping brake shoe is attached.

Die Erfindung wird an Hand des in den Zeichnungen dargestellten Ausführungsbeispiels erläutert. Es zeigt F i g. 1 einen Längsschnitt durch die Bremsanlage und F i g. 2 einen Schnitt durch die Bremse nach der Linie A -A in F i g. 1. The invention is explained using the exemplary embodiment shown in the drawings. It shows F i g. 1 shows a longitudinal section through the brake system and FIG. 2 shows a section through the brake along the line A -A in FIG. 1.

Im Achsgehäuse 1 ist eine Bremsscheibe 2 angeordnet, die mit der Welle 4, auf der sie in axialer Richtung schwimmend angeordnet ist, über eine Keilverbindung 5 drehfest verbunden ist. In dem mit dem Achsgehäuse 1 verschraubten Deckel 6 ist auf einem Bolzen 8 ein U-förmiger Bremssattel 9 schwenkbar gelagert, mit dem die Bremsbacken 10 über gekrümmte Flächen 11 formschlüssig verbunden sind. Die vom Fahrer aufgebrachte Fußkraft wird über den Hebel 7 und das Gestänge 12 auf den Bremssattel 9 übertragen. Die Bremsscheibe 2 ist mit einer V-förmigen Nut 3 versehen, in die die Bremsbacke 16 ragt. Die vom Fahrer aufgebrachte Handkraft wird über das Gestänge 15 und den über einen Bolzen 14 im Deckel 6 gelagerten Hebel 13 auf die Bremsbacke 16 übertragen. Der Pfeil E in F i g. 2 gibt die Drehrichtung der Bremsscheibe bei Vorwärtsfahrt an.A brake disc 2 is arranged in the axle housing 1 and is connected to the shaft 4, on which it is floating in the axial direction, in a rotationally fixed manner via a spline connection 5. In the cover 6 screwed to the axle housing 1, a U-shaped brake caliper 9 is pivotably mounted on a bolt 8 , with which the brake shoes 10 are positively connected via curved surfaces 11. The foot force applied by the driver is transmitted to the brake caliper 9 via the lever 7 and the linkage 12. The brake disc 2 is provided with a V-shaped groove 3 into which the brake shoe 16 protrudes. The manual force applied by the driver is transmitted to the brake shoe 16 via the linkage 15 and the lever 13 mounted in the cover 6 via a bolt 14. The arrow E in FIG. 2 indicates the direction of rotation of the brake disc when driving forward.

Die abzubremsende Bremsscheibe 2 will die bei der Betätigung des Hebels 7 angepreßten Bremsbacken 10 in Pfeilrichtung E über den Reibungsschluß mitnehmen. Dadurch werden infolge der exzentrischen Lagerung des Bremssattels 9 Drehmomente auf den Bremssattel 9 wirksam, welche eine Selbstverstärkung der Bremskraft bewirken. Das Maß der Selbstverstärkung ist am größten, wenn die Bremsbacken neu sind. Bei abgenutzten Bremsbacken ist das Maß der Selbstverstärkimg gering-fügig kleiner.The brake disc 2 to be braked wants to take along the brake shoes 10, which are pressed on when the lever 7 is actuated, in the direction of the arrow E via the frictional connection. As a result of the eccentric mounting of the brake caliper 9, torques are effective on the brake caliper 9 , which cause a self-amplification of the braking force. The degree of self-reinforcement is greatest when the brake shoes are new. If the brake shoes are worn, the amount of self- energizing is slightly smaller.
