Description

Die Erfindung betrifft einen Riemenspanner für einen Nebenaggregate-Riementrieb einer Brennkraftmaschine, vorwiegend im P0 System, aufweisend:

  • - eine ringförmige Basis, die die Drehachse eines Generators umschließend auf dem Generator zu befestigen ist,
  • - einen ringförmigen Spannarm, der auf der Basis mittels eines Gleitlagers radial und axial gelagert ist,
  • - eine am Spannarm angebrachte Spannrolle, die den Riemen mit Vorspannkraft beaufschlagt,
  • - und eine Feder, die die Vorspannkraft erzeugt.
The invention relates to a belt tensioner for an auxiliary unit belt drive of an internal combustion engine, primarily in the P0 system, having:
  • - a ring-shaped base to be fixed on the generator surrounding the axis of rotation of a generator,
  • - an annular tensioning arm radially and axially mounted on the base by means of a sliding bearing,
  • - a tensioning pulley attached to the tensioning arm, which applies pretensioning force to the belt,
  • - and a spring that generates the preload force.

Gattungsgemäße Riemenspanner sind mit einem einzigen Spannarm aus DE 10 2014 203 952 A1 und mit zwei Spannarmen aus DE 10 2015 210 002 A1 und DE 10 2016 217 933 A1 bekannt. Das jeweils eingebaute Gleitlager, das den Spannarm auf der Basis lagert, ist konstruktiv als mehrteiliger Belag ausgeführt.Generic belt tensioners are made with a single tensioning arm DE 10 2014 203 952 A1 and with two clamping arms DE 10 2015 210 002 A1 and DE 10 2016 217 933 A1 known. The plain bearing that is installed in each case, which mounts the clamping arm on the base, is designed as a multi-part covering.

Die EP 3 161 346 B1 schlägt vor, das Gleitlager mittels Federkraft vorzuspannen, um eine betriebliche Verkippung des Spannarms im Gleitlager zu verhindern. Dämpfung zu erhöhen ohne gleichzeitig der Verkippung entgegenwirkende Momente zu erzeugen ist durch eine zusätzliche Feder nicht möglich.the EP 3 161 346 B1 suggests preloading the plain bearing by means of spring force in order to prevent operational tilting of the tension arm in the plain bearing. An additional spring cannot be used to increase damping without at the same time generating moments that counteract the tilting.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Riemenspanner hinsichtlich des Gleitlagers konstruktiv zu verbessern.The object of the present invention is to structurally improve a generic belt tensioner with regard to the sliding bearing.

Die Lösung dieser Aufgabe ergibt sich durch Ausformen der beiden Lagerhälften in Keil- und Nutgeometrie. Bei ankommender Lagerlast (resultierende Radialkraft) wird der Keil in die Nut gepresst. Die Keilgeometrie bewirkt:

  • 1) erhöhtes Reibungsniveau durch größere Reibflächen (erhöhter Traganteil)
  • 2) gleichmäßigeres Reibniveau von Beginn an durch Selbstzentrierung der Flächen zueinander
  • 3) selbstverstärkende Dämpfung bei Erhöhung der Lagerlast
  • 4) weniger Verkippung über Lebenszeit durch Eliminierung der Axialluft im Lastbereich
This task is solved by forming the two halves of the bearing with a wedge and groove geometry. When the bearing load arrives (resulting radial force), the wedge is pressed into the groove. The wedge geometry causes:
  • 1) increased level of friction due to larger friction surfaces (increased contact area)
  • 2) more even friction level right from the start through self-centering of the surfaces to each other
  • 3) self-reinforcing damping when bearing load increases
  • 4) less tilting over lifetime by eliminating the axial clearance in the load area

Weitere Merkmale und vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung und aus den Zeichnungen, in denen ein Ausführungsbeispiel eines erfindungsgemäßen Riemenspanners eines Nebenaggregate-Riementriebs einer Brennkraftmaschine mit einer riemengetriebenen Start-Stopp-Einrichtung (P0 System) dargestellt ist. Der Riemenspanner ist mit zwei Spannarmen als sogenannter Pendelspanner ausgeführt und auf einem Startergenerator angeordnet. Es zeigen:

  • 1 den Riemenspanner im Längsschnitt;
  • 2 die Einzelheit Z aus 1;
  • 3 die Einzelheit Z in perspektivischer Explosion.
Further features and advantageous embodiments of the invention result from the following description and from the drawings, in which an exemplary embodiment of a belt tensioner according to the invention of an auxiliary unit belt drive of an internal combustion engine with a belt-driven start-stop device (P0 system) is shown. The belt tensioner is designed with two tensioning arms as a so-called pendulum tensioner and is arranged on a starter generator. Show it:
  • 1 the belt tensioner in longitudinal section;
  • 2 the detail Z out 1 ;
  • 3 the detail Z in a perspective explosion.

Der in 1 dargestellte Riemenspanner 1 wird auf die riemenseitige Front des Startergenerators montiert, der nicht nur als (angetriebener) Generator zur Stromerzeugung, sondern auch als (antreibender) Motor zum Riemenstart oder Boosten der Brennkraftmaschine betrieben wird. Der Riemenspanner 1 umfasst eine auf dem Startergenerator zu befestigende Basis 2, die ringförmig geschlossen ist und die Generatordrehachse 12 umschließt. Auf der Basis 2 ist ein erster, ebenfalls ringförmig geschlossener Spannarm 3 um die Generatordrehachse drehbar gelagert. Ein zweiter Spannarm 4 ist auf dem ersten Spannarm 3 um eine Spannarmachse 5 drehbar gelagert und mittels einer Feder 6 gegen den ersten Spannarm 3 angefedert. Beide Spannarme 3, 4 sind mit Spannrollen versehen, von denen in der Figur nur die am ersten Spannarm 3 angeschraubte Spannrolle 7 sichtbar ist. Die als Drehfeder ausgebildete Feder 6 spannt mittels der Spannrollen das sich betriebsabhängig mit dem Zugtrum vertauschende Leertrum des Riemens vor.the inside 1 Belt tensioner 1 shown is mounted on the belt-side front of the starter generator, which is operated not only as a (driven) generator to generate electricity, but also as a (driving) motor for belt starting or boosting the internal combustion engine. The belt tensioner 1 comprises a base 2 to be fastened on the starter generator, which is closed in the form of a ring and encloses the generator axis of rotation 12 . On the base 2, a first, also ring-shaped closed clamping arm 3 is rotatably mounted about the generator axis of rotation. A second clamping arm 4 is rotatably mounted on the first clamping arm 3 about a clamping arm axis 5 and spring-loaded against the first clamping arm 3 by means of a spring 6 . Both clamping arms 3, 4 are provided with clamping rollers, of which only the clamping roller 7 screwed to the first clamping arm 3 is visible in the figure. The spring 6 designed as a torsion spring pretensions the slack side of the belt, which is interchanged with the tight side depending on the operation, by means of the tension rollers.

Die Lagerung des ersten Spannarms 3 auf der Basis 2 erfolgt mittels eines Gleitlagers 8, das in den 2 und 3 in Detailansicht dargestellt ist. Das Gleitlager 8 hat eine Keilgeometrie und umfasst zwei Lagerhälften, von denen eine als Keil auf der Basis 2 und die andere als Nut ausgebildet ist. Die zur Keilform komplementäre Nut ist durch zwei Gleitlagerringe 9 und 10 aus Polyamid gebildet, die axial spielbehaftet zwischen dem ersten Spannarm 3 und einer darin eingepressten Verschlusshülse 11 aufgenommen sind und den Keil einfassen.The storage of the first clamping arm 3 on the base 2 is done by means of a sliding bearing 8 in the 2 and 3 shown in detail. The slide bearing 8 has a wedge geometry and comprises two bearing halves, one of which is designed as a wedge on the base 2 and the other as a groove. The groove complementary to the wedge shape is formed by two plain bearing rings 9 and 10 made of polyamide, which are received with axial play between the first clamping arm 3 and a closure sleeve 11 pressed into it and enclose the wedge.
