Abstract

Two-piece brake disc for disc-brake systems, particularly those in motor vehicles, characterised in that it consists of two parts joined together by welding, with a formed fastening disc and a likewise formed multi-knob disc which is provided with a multiplicity of uniformly distributed polygonal knobs, of which the inner knobs are arranged on an inner-knob circle and the outer knobs are arranged on an outer-knob circle, the discs being joined together by tangential seam welds in the region of the inner and outer knobs and/or by spot welds in the region of the inner and outer knobs, the brake disc also being characterised by the cooling-air ducts formed by the knob arrangement, these ducts being interrupted by the arrangement of the knobs so as to increase the cooling effect by means of air turbulence. <IMAGE>

Description

Die Erfindung bezieht sich auf eine zweiteilige Brems­ scheibe für Scheibenbremsanlagen von Kraftfahrzeugen, der im Oberbegriff des Patentanspruches 1 genannten Art.The invention relates to a two-part brake disc for motor vehicle disc brake systems, the type mentioned in the preamble of claim 1.

Es ist bekannt, für Scheibenbremsanlagen Bremsscheiben aus zwei Scheibenteilen zu fertigen (DE-OS 19 40 669, DE 32 41 549 A1, DE 34 32 926 A1) oder einteilige Brems­ scheiben zur Erhöhung der Kühlwirkung mit unterbrochenen Kühlkanälen zu versehen (G 87 08 264.0).It is known for disc brake systems brake discs to be produced from two disc parts (DE-OS 19 40 669, DE 32 41 549 A1, DE 34 32 926 A1) or one-piece brake discs to increase the cooling effect with interrupted Cooling channels to be provided (G 87 08 264.0).

Diese Ausführungen haben den Nachteil, daß sie entweder zu teuer und aufwendig in der Fertigung sind oder auf­ grund ihrer Ausführung zu ungleichmäßigen Erwärmungen und damit Verwerfungen neigen und/oder unerwünschte Bau­ teilschwindungen auftreten.These designs have the disadvantage that they are either are too expensive and complex to manufacture or on due to their execution to uneven heating and thus tend to warp and / or undesirable construction partial shrinkage occurs.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine aus zwei Scheibenhälften bestehende Bremsscheibe zu schaffen, bei der die hohen thermischen und mechanischen Anforderungen durch bewährte Fertigungs- und Fügeverfahren auf wirtschaftliche Art und Weise erfüllt werden.The invention is based on the object a brake disc consisting of two disc halves create where the high thermal and mechanical Requirements through proven manufacturing and joining processes be met in an economical manner.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die beiden Scheibenhälften mit durch Massivumformung ausge­ bildeten Nocken versehen sind, welche aufgrund ihrer Aus­ bildung als Kühlluftkanäle dienen und weiterhin zur Ver­ bindung der beiden Scheibenhälften benutzt werden.The object is achieved in that the two disc halves with massive forming formed cams are provided, which due to their Aus education serve as cooling air channels and continue to Ver binding of the two disc halves can be used.

Die mit der Erfindung erzielten Vorteile bestehen insbe­ sondere darin, daß die beiden Scheibenhälften durch be­ währte Umformverfahren (Schmieden, Kaltmasivumformung) und Verbindungsverfahren (Schmelzschweißen, Widerstands­ punktschweißung) sehr wirtschaftlich gefertigt und ver­ bunden werden können.The advantages achieved with the invention are in particular special in that the two disc halves by be proven forming processes (forging, cold massive forming) and joining processes (fusion welding, resistance spot welding) manufactured very economically and ver can be bound.

Insbesondere erfüllt die Bremsscheibe in gleicher Weise, sowohl die hohen mechanischen Anforderungen (Bremsmoment­ übertragung, Schwingungssteifigkeit, Verwerfungssicher­ heit) durch ihre massive oder teilmassive Ausführung und die sicheren Verbindungsverfahren als auch die thermischen Anforderungen (Temperaturbeständigkeit, Temperaturaus­ gleich, Kühlleistung) aufgrund der durch die Nockenanord­ nung sinnvoll gebildeten und zur Verstärkung der Kühlwir­ kung durch die Kühlkanalunterbrechung entstehenden Kreuz­ strömungen sowie temperaturausgleichverstärkende Verbin­ dungsflächen.In particular, the brake disc fulfills in the same way, both the high mechanical requirements (braking torque transmission, vibration rigidity, distortion-proof unit) due to their massive or partially massive design and the safe connection methods as well as the thermal ones Requirements (temperature resistance, temperature off equal, cooling capacity) due to the by the cam arrangement sensible education and to reinforce the cooling cross caused by the interruption in the cooling channel flows as well as a temperature compensation reinforcing connection  development areas.

Die Bilder 1-4 zeigen verschiedene Ausführungsvarian­ ten, wobei die Bremsscheibe nach Bild 1 beschrieben ist unter Anspruch 1, Bild 2 beschrieben nach Anspruch 2, Bild 3 nach Anspruch 3 und Bild 4 nach Anspruch 4. Figures 1-4 show different design variants, the brake disc according to Figure 1 being described under Claim 1, Figure 2 described according to Claim 2, Figure 3 according to Claim 3 and Figure 4 according to Claim 4.

Die Erfindung ist bezüglich der dargestellten Nocken­ profilform nicht auf das dargestellte Polygonprofil be­ schränkt, so können die drei Eckenradien des Nockens auch durch sinnvolle Kurvenzüge verbunden sein.The invention is related to the cams shown profile shape not on the polygon profile shown limits, the three corner radii of the cam also be connected by meaningful curves.
