Abstract
Description
Die Erfindung betrifft eine Riemenscheibe mit Dreh schwingungsdämpfer für einen Riementrieb, insbesondere an einer Brennkraftmaschine, gem. dem Oberbegriff des Patentanspruches 1.The invention relates to a pulley with rotation Vibration damper for a belt drive, in particular on an internal combustion engine, acc. the generic term of Claim 1.
Eine derartige Riemenscheibe mit Drehschwingungsdämpfer zeigt beispielsweise die PCT-Anmeldung WO91/021 76. Dabei ist die Riemenscheibe einstückig aus Metallblech geformt und trägt am Innenumfang ihrer Riemenspur über eine elastomere Zwischenschicht die Sekundärmasse. Zur axialen Sicherung der Sekundärmasse ist die Riemenspur mit einem radial nach innen ragenden Kragen versehen.Such a pulley with torsional vibration damper shows for example PCT application WO91 / 021 76. The pulley is made in one piece from sheet metal shaped and transferred to the inside circumference of their belt track an elastomeric intermediate layer the secondary mass. For Axial securing of the secondary mass is the belt track provided with a collar projecting radially inwards.
Aufgabe der Erfindung ist es, eine herstellungstechnisch einfache und kostengünstige Riemenscheibe vorzuschlagen, bei der die Sekundärmasse sicher und problemlos montier bar an der Riemenscheibe gehalten ist.The object of the invention is a manufacturing technology propose simple and inexpensive pulley, where the secondary mass can be mounted safely and easily is held on the pulley bar.
Diese Aufgabe wird erfindungsgemäß mit den kennzeichnen den Merkmalen des Patentanspruches 1 gelöst. Vorteilhaf te Weiterbildungen der Erfindung sind den weiteren Pa tentansprüchen entnehmbar. According to the invention, this object is characterized by the solved the features of claim 1. Advantageous te further developments of the invention are the further Pa claims can be removed.
Erfindungsgemäß ist an den Anschlußflansch z. B. im Zieh verfahren ein axial verlaufendes Nabenteil angeformt, welches funktionsmäßig in das radial verlaufende Schei benteil übergeht und die Sekundärmasse trägt. Diese Ausbildung hat den Vorteil einer einstückigen Herstell barkeit der Riemenscheibe, ohne jedoch die Sekundärmasse an der Riemenspur anbinden zu müssen, was festigkeitsmä ßig und bei der Montage der Sekundärmasse problematisch sein kann.According to the z. B. in the pull an axially extending hub part is formed, which functionally in the radially extending Schei part passes over and carries the secondary mass. This Training has the advantage of being made in one piece Availability of the pulley, but without the secondary mass to have to tie to the belt track, what strength ßig and problematic when installing the secondary mass can be.
Bevorzugt können der Anschlußflansch und das Scheiben teil bzw. deren Radialebenen nahe beieinander liegen und das Nabenteil doppelwandig ausgebildet sein. Dies hat den Vorteil einer hohen Festigkeit im Nabenbereich zur Aufnahme der Sekundärmasse und bedingt zudem eine bau lich sehr günstige, kompakte Anordnung der Riemenspur zum Anschlußflansch. Besonders vorteilhaft kann das doppelwandige Nabenteil durch Übereinanderstülpen axial verlaufender Nabenabschnitte hergestellt sein, insbeson dere in einstückiger Bauweise.Preferably, the connecting flange and the washers part or their radial planes are close to each other and the hub part may be double-walled. this has the advantage of high strength in the hub area Inclusion of the secondary mass and also requires construction Lich very cheap, compact arrangement of the belt track to the connection flange. This can be particularly advantageous double-walled hub part by slipping axially extending hub sections be made, in particular one in one piece.
Ferner kann das Nabenteil mit einer ringförmigen Ein schnürung versehen sein, die zur Erhöhung der Festigkeit des Nabenteiles dient und zugleich eine formschlüssige, axiale Sicherung der Sekundärmasse mit herstellt. Durch diese Ausgestaltung kann ferner die Sekundärmasse nur durch Einspritzen oder einer gummielastischen bzw. ela stomeren Dämpfungsschicht gehalten sein.Furthermore, the hub part with an annular one lacing provided to increase strength serves the hub part and at the same time a form-fitting, with axial securing of the secondary mass. By this configuration can also only the secondary mass by injection or a rubber elastic or ela stomeric damping layer can be kept.
Ein Ausführungsbeispiel der Erfindung ist im folgenden mit weiteren Einzelheiten näher erläutert.An embodiment of the invention is as follows explained in more detail with further details.
Die anliegende Zeichnung zeigt einen Querschnitt durch eine erfindungsgemäße Riemenscheibe aus Metallblech in einstückiger Bauweise mit einer aufmontierten Sekundär masse.The attached drawing shows a cross section through a metal pulley according to the invention in one-piece construction with an attached secondary Dimensions.
Die dargestellte Riemenscheibe 10 für einen Poly-V-Rie mentrieb an einer Brennkraftmaschine setzt sich im we sentlichen zusammen aus einem radial verlaufenden Flanschteil 12, einem daran anschließenden, axial ver laufenden Nabenteil 14, einem wiederum radial verlaufen den Scheibenteil 16 und einer daran anschließenden Rie menspur 18.The belt pulley 10 shown for a poly-V belt drive on an internal combustion engine is composed essentially of a radially extending flange part 12 , an adjoining axially running hub part 14 , a radially running disk part 16 and a subsequent Rie mens track 18 .
Das Nabenteil 14 ist doppelwandig ausgebildet, in dem ein erster nabenförmiger Abschnitt 20 an den Anschluß flansch 12 angeformt und ein zweiter nabenförmiger Ab schnitt 22 durch Umstülpen darübergelegt (z. B. gerollt) ist und in das Scheibenteil 16 übergeht.The hub part 14 is double-walled, in which a first hub-shaped section 20 is integrally formed on the connection flange 12 and a second hub-shaped section 22 is laid over (for example rolled) by turning it over and merges into the disk part 16 .
Dabei liegen das Scheibenteil 16 und der Anschlußflansch 20 hinsichtlich deren Rotationsmittelebenen 24, 26 nahe beieinander, während die Riemenspur 18 mit dem Nabenteil 14 im wesentlichen eine einheitliche Rotationsmittelebe ne 28 bildet. The disc part 16 and the connecting flange 20 are close to each other with respect to their rotational center planes 24, 26 , while the belt track 18 with the hub part 14 essentially forms a uniform rotational center plane 28 .
Das Nabenteil 14 weist insgesamt eine ringförmige Ein schnürung 30 auf, über der eine ringförmige Sekundärmas se 32, z. B. ein Stahlring, angeordnet ist. Zur elasti schen Halterung der Sekundärmasse 32 ist ein durch Spritzgießen oder Einpressen eingebrachter Elastomer- oder Gummiring 34 vorgesehen. Durch die Einschnürung 30 in Verbindung mit der Auswölbung 31 am Innenumfang der Sekundärmasse 32 ist eine axiale Sicherung geschaffen, die einen zuverlässigen Haftsitz der Sekundärmasse 32 auf dem Nabenteil 14 gewährleistet.The hub part 14 has a total of an annular lacing 30 , over which an annular secondary se 32 , z. B. a steel ring is arranged. For elastic retention of the secondary mass 32 , an elastomer or rubber ring 34 introduced by injection molding or pressing in is provided. The constriction 30 in connection with the bulge 31 on the inner circumference of the secondary mass 32 creates an axial securing which ensures a reliable tight fit of the secondary mass 32 on the hub part 14 .
Wie aus der Zeichnung ohne weiteres ersichtlich ist, ist die Riemenscheibe 12, 14, 16, 18 einstückig aus einem Me tallblech im einschlägigen Zieh-, Falz- und Stauchver fahren hergestellt. Nach deren Herstellung wird die Se kundärmasse 32 aufgebracht, zentrisch fixiert und dann die Dämpfungsmasse 34 durch Spritzgießen oder Einpressen angeordnet. Die doppelwandige Ausbildung des Nabenteiles 14 stellt dabei sicher, daß während der Montage des Se kundärringes 32 keine unzulässige Verformung der Riemen scheibe auftritt.As can be seen from the drawing without further notice, the pulley 12 , 14 , 16 , 18 is made in one piece from a tall sheet metal in the relevant drawing, folding and compression process. After their manufacture, the secondary mass 32 is applied, fixed centrally, and then the damping mass 34 is arranged by injection molding or pressing. The double-walled design of the hub part 14 ensures that no unacceptable deformation of the belt pulley occurs during the assembly of the secondary ring 32 .
