Abstract

The electrically operated partially lined disc brake for motor vehicles has a magnetic coil (8) fixed as a stator in a cylindrical calliper extension whilst the magnetic armature (9) exerts a translated tension force via a plate spring (6) and the axially movable shoe (5). ADVANTAGE - Thermal load on electrical operating points is kept to min.

Description

Elektrisch betätigte Fahrzeugbremsen bieten den wesentlichen Vorteil, daß deren Antiblockiersteuerung ohne ein Fluid- Modulation mit Nachfüllpumpeinrichtung, also hysteresefrei erfolgen kann.Electrically operated vehicle brakes offer the essentials Advantage that their anti-lock control without a fluid Modulation with refill pump device, i.e. hysteresis-free can be done.

Bisher sind elektrisch betätigte Scheibenbremsen bekannt, bei denen ein Lamellenpaket mit elektrischer Durchflutung oder durch konzentrisch zum Lamellenpaket angeordneten Magneten geschlossen wird. Diese Lösungen erfordern das mehr­ fache Gewicht einer heutigen Kraftwagenbremse und weisen eine begrenzte thermische Belastbarkeit auf, zumal sie ausgespro­ chene Wärmespeicherbremsen darstellen.So far, electrically operated disc brakes are known in which a plate pack with electrical flow or arranged concentrically to the plate pack Magnet is closed. These solutions require more times the weight of a motor vehicle brake today and have one limited thermal resilience, especially since they try out represent heat storage brakes.

Die direkte elektromagnetische Betätigung einer Teilbelag­ scheibenbremse für Kraftfahrzeuge ist nicht möglich, weil ein Magnet dafür zu schwer ausfallen würde und nicht unterge­ bracht werden könnte. Auch aus thermischen Gründen kann ein Magnetanker nicht direkt mit der Betätigungsbacke einer Teil­ scheibenbremse verbunden werden.The direct electromagnetic actuation of a partial covering disc brake for motor vehicles is not possible because a magnet would turn out to be too heavy for this and not undershot could be brought. For thermal reasons, too Magnetic armature not directly with the actuating jaw of a part disc brake can be connected.

Die Erfindung hat sich zur Aufgabe gesetzt, eine elektrische Betätigung für eine Kraftwagen-Teilscheibenbremse zu schaffen, bei der die genannten Nachteile ausgeschaltet sind und die Vorteile einer hysteresefreien ABS genutzt werden können, ohne daß die thermische Belastung der elektrischen Betätigungsteile unzulässig hoch wird.The invention has set itself the task of an electrical To create actuation for a motor vehicle disc brake, in which the disadvantages mentioned are eliminated and the Advantages of a hysteresis-free ABS can be used without that the thermal load on the electrical actuators becomes unacceptably high.

Die Aufgabe der Erfindung wird durch die kennzeichnenden Merk­ male des Anspruchs gelöst.The object of the invention is by the characterizing note Male of the claim solved.

In der Abbildung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Der in der Abbildung mit 1 gekennzeich­ neten hohlen Bremsscheibe liegt auf der Seite des Sattels 2 der Reibbelag 3 gegenüber. Der Gegenreibbelag 4 sitzt auf dem im Sattel axial bewglich angordneten Backen 5, der sein Brems­ moment über Fortsätze 6 in den Sattel 2 leitet. Der Backen 5 weist einen Hohlzylinder 5 1 auf mit einem Runddrahtring, an dem die Übersetzungs-Tellerfeder 6 anliegt. Im zylindrischen Sat­ telfortsatz 2 1 stützt sich die Tellerfeder auf einem Spreng­ ring 7 ab. In diesem Sattelfortsatz ist die Magnetspule 8 als Stator der elektrischen Betätigung angebracht und durch den Zylindermantel gekühlt und gegen Überhitzung geschützt. Unter Strom gesetzt zieht sie den axial beweglichen zylindrischen Anker 9 an, der über seinen zentrischen Fortsatz 9 1 mit Draht­ ring 9 2 die Tellerfeder 6 spannt und mit übersetzter Kraft den Backen 5 mit Reibbelag 4 gegen die umlaufende Bremsscheibe 1 drückt und dabei gleichzeitig den Reibbelag 3 mit dem Sattel anzieht und auch den Reibbelag 4 an die Bremsscheibe anlegt und die Bremsung einleitet.In the figure, an embodiment of the invention is shown schematically. The marked in the figure with 1 Neten hollow brake disc is on the side of the saddle 2 of the friction lining 3 opposite. The counter friction lining 4 sits on the axially movably arranged jaws 5 , which directs its braking moment via extensions 6 into the saddle 2 . The jaw 5 has a hollow cylinder 5 1 with a round wire ring on which the translation plate spring 6 rests. In the cylindrical satellite extension 2 1 , the plate spring is supported on an explosive ring 7 . In this saddle extension, the magnet coil 8 is attached as a stator for electrical actuation and is cooled by the cylinder jacket and protected against overheating. When energized, it pulls the axially movable cylindrical armature 9 , which clamps the plate spring 6 via its central extension 9 1 with a wire ring 9 2 and presses the jaws 5 with the friction lining 4 against the circumferential brake disc 1 while at the same time pressing the friction lining 3 attracts with the saddle and also applies the friction lining 4 to the brake disc and initiates braking.
