Abstract
Description
Die Erfindung betrifft eine Bremsvorrichtung nach dem Oberbegriff des Anspruchs 1. Des Weiteren betrifft die Erfindung ein Verfahren zum Herstellen einer solchen Bremsvorrichtung.The The invention relates to a braking device according to the preamble of Claim 1. Furthermore, the invention relates to a method for Producing such a braking device.
Aus
der
Hiervon ausgehend liegt der hier vorliegenden Erfindung die Aufgabe zugrunde, eine neuartige Bremsvorrichtung zu schaffen.Of these, Based on the present invention, the object is based, to create a novel braking device.
Diese Aufgabe wird durch eine Bremsvorrichtung gemäß Anspruch 1 gelöst. Erfindungsgemäß weist die Bremstrommel über den Umfang derselben verteilt mehrere Ausnehmungen auf, wobei der Bremstopf mit der Bremstrommel derart vergossen ist, dass sich der Bremstopf unter Ausbildung von Stiften in die Ausnehmungen der Bremstrommel hinein erstreckt.These Task is achieved by a braking device according to claim 1 solved. According to the invention, the brake drum over the circumference of the same distributed on several recesses, the Bremstopf is shed with the brake drum such that the Brake pot with the formation of pins in the recesses of the brake drum inside extends.
Erfindungsgemäß wird vorgeschlagen, den Bremstopf und die Bremstrommel miteinander zu vergießen, wobei die Bremstrommel mehrere Ausnehmungen aufweist, die über den Umfang derselben verteilt sind, und wobei der Bremstopf unter Ausbildung von Stiften, die sich in die Ausnehmungen der Bremstrommel hinein erstrecken, mit der Bremstrommel vergossen ist. Hierdurch wird eine besonders innige Verbindung zwischen dem Bremstopf und der Bremstrommel bereitgestellt, wodurch eine besonders betriebssichere und robuste Bremsvorrichtung ausgebildet werden kann.According to the invention proposed to shed the brake pot and the brake drum together, wherein the brake drum has a plurality of recesses over the circumference of the same are distributed, and wherein the brake pot under Formation of pins that fit into the recesses of the brake drum extend into it, is shed with the brake drum. hereby is a particularly intimate connection between the brake pot and the Brake drum provided, creating a particularly reliable and robust braking device can be formed.
Durch die sich in die Ausnehmungen der Bremstrommel hinein erstreckenden Stifte des Bremstopfs wird eine gute radiale und axiale Fixierung sowie Drehmomentfixierung zwischen Bremstopf und Bremstrommel bereitgestellt.By extending into the recesses of the brake drum Pins of the brake pot will have a good radial and axial fixation and torque fixation between brake pot and brake drum provided.
Unterschiedliche Wärmeausdehnungskoeffizienten der Werkstoffe von Bremstopf und Bremstrommel wirken sich, im Unterschied zu aus dem Stand der Technik bekannten Bremsvorrichtungen, positiv aus, da die unterschiedlichen Wärmeausdehnungskoeffizienten die Fixierung und Verbindung zwischen dem Bremstopf und der Bremstrommel verbessern.different Thermal expansion coefficient of the materials of brake pot and brake drum affect, in contrast to from the state of the Technically known braking devices, positive, since the different Thermal expansion coefficient the fixation and connection between improve the brake pot and the brake drum.
Im Verbindungsbereich zwischen Bremstopf und Bremstrommel treten im Betrieb keine unerwünschten Radialkräfte auf. Vielmehr erfolgt eine Scherbelastung über den Verbindungsbereich.in the Connection area between brake pot and brake drum occur in Operation no unwanted radial forces. Rather, there is a shear stress on the connection area.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ausführungsbeispiele der Erfindung werden, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert. Dabei zeigt:preferred Further developments of the invention will become apparent from the dependent claims and the description below. Embodiments of the Invention are provided without being limited thereto explained in detail the drawing. Showing:
Die hier vorliegende Verbindung betrifft eine Bremsvorrichtung, die zumindest einen Bremstopf, eine Bremstrommel zur Bereitstellung einer Feststellbremsfunktion und eine Bremsscheibe zur Bereitstellung einer Betriebsbremsfunktion umfasst. Einerseits ist die Bremstrommel für die Feststellbremsfunktion und andererseits die Bremsscheibe für die Betriebsbremsfunktion mit dem Bremstopf verbunden. Die hier vorliegende Erfindung betrifft solche Details einer Bremsvorrichtung, über welche die Verbindung zwischen dem Bremstopf und der Bremstrommel für die Feststellbremsfunktion verbessert werden kann.The The present invention relates to a brake device which at least one brake pot, a brake drum for providing a parking brake function and a brake disk for provision a service brake function. On the one hand is the brake drum for the parking brake function and on the other hand, the brake disc for the service brake function connected to the brake pot. The present invention relates to such details of a braking device, via which the connection between the brake pot and the brake drum can be improved for the parking brake function.
