BremsklotzBrake pad

Die Erfindung macht sich zur Aufgabe, einen Bremsklotz zu schaffen, der von. Beginn seiner Inbetriebnahme an auf seiner ganzen Reibfläche zur Anlage kommt und auch bei unrund abgelaufenen. Rädern stets mit seiner ganzen Bremsfläche wirksam, ist.The invention has as its object to provide a brake pad that of. Beginning its commissioning comes to rest on its entire friction surface and also with unround expired. Wheels is always effective with its entire braking surface.

Diese Forderungen werden von den bisher bekanntgewordenen Bremsklötzen nicht erfüllt. Man hat zwar seihon versucht, die angegebene Aufgabe dadurch, zu lösen, daß man Bremsklötze geschaffen hat, die in radialer Richtung, also· senkrecht zur Radtangente, mit Schlitzen verseilen sind. Solche Bremsklötze passen sich zwar Radradien an, die größer sind als der Krümmungsradius des Klotzes, indem sie sich zufolge der Schlitze federnd aufbiegen. Sie vermögen sich indessen nicht vollständig anzulegen, wenn sie einem· Rad zugeordnet werden, dessen Krümmungsradius ao kleiner ist als der des Klotzes. Weiterhin ist es mit den bisher bekanntgewordenen Bremsklötzen nicht möglich, eine Anlage über die ganze Reibfläche am Klotz sicherzustellen, wenn unrunde Räder gebremst werden sollen;, da dann in dem Augenblick, wo die Stelle des •unrunden Rades, die die größte Entfernung von der Radachse aufweist, vor den Klotz gelangt, der Klotz allein an dieser Stelle anliegt, während zwischen den anderen Teilen der Bremsfläche des Klotzes und dem Rad Spiel bleibt.These demands are from the hitherto brake pads that have become known are not met. It is true that one has tried to solve the given problem by Has created brake pads, which in the radial direction, that is · perpendicular to the wheel tangent, with Are stranding slots. Such brake pads adapt to the larger wheel radii are resilient than the radius of curvature of the block by being resilient as a result of the slots bend up. However, they are not able to apply themselves completely when they are attached to a wheel be assigned whose radius of curvature ao is smaller than that of the block. Furthermore is it is not possible with the brake pads that have become known so far, a system on the ensure the entire friction surface on the block if non-round wheels are to be braked ;, then at the moment when the place of the • the out-of-round wheel, which is the greatest distance from the wheel axle, in front of the block arrives, the block rests alone at this point, while between the other parts the braking surface of the block and the wheel play remains.

Diese Mängel der bekannten Bremsklötze werden gemäß der Erfindung dadurch beseitigt, daß die Bremsklotzsohle in der Weise mit Schlitzen versehen wird, daß sie in Richtung des Andruckes in sich federt. Hierbei versieht man die Klotzsohle am besten mit von jeder ihrer Flachseiten her hineingearbeiteten, gegen die Andruckrichtung geneigt verlaufenden Schlitzen, die so- angeordnet sind, daß die von der einen Seite her eingearbeiteten Schlitze die von der anderen Seite her eingearbeiteten Schlitze kreuzweise schneiden. Solche Klotzsohlen zeichnen sich durch die Eigenschaft aus, daß sie in der Andruckrichtung gewissermaßen schmiegsam sind, so 'daß sie sich unter allen Umständen selbst bei unrund gelaufenen Rädern jederzeit mit ihrer ganzen Bremsaberfläche an den Umfang des zu bremsenden Rades anlegen.These shortcomings of the known brake pads are eliminated according to the invention by that the brake shoe is slotted in such a way that it faces of the pressure resides in itself. It is best to provide the block sole with worked into it from each of its flat sides, slits that are inclined against the direction of pressure and are arranged in such a way that that the slots worked in from one side are those from the other side Cut the incorporated slots crosswise. Such block soles are characterized by the Property from the fact that they are to some extent pliable in the direction of pressure, so 'that under all circumstances, even if the wheels are not running properly Place the entire braking surface on the circumference of the wheel to be braked.

Wie die neue. Bremsklotzsohle beispielsweise ausgeführt zu denken ist, geht anis den Abb. ι und 2 hervor, in denen der Bremsklotzhalter mit i, die Bremsklotzsohle mit 2 und das abzubremsende Rad mit 3 bezeichnet ist. Der Verlauf der Schlitze, die der' Sohle ihre Fähigkeit, sich an den Radumfang anzuschmiegen, geben, ist aus den Abbildungen ohne weitere Erläuterungien erkennbar.Like the new one. Brake block sole is to be thought of running, for example, goes anis the Fig. Ι and 2, in which the brake pad holder with i, the brake pad sole with 2 and the wheel to be braked is denoted by 3. The course of the slots that the ' The sole showing its ability to hug the circumference of the wheel is evident from the illustrations recognizable without further explanations.
