Description

  

      Einrichtung        zur    gummielastischen     Lagerung    des Triebaggregates im freitragenden Aufbau  von     Kraftfahrzeugen       Die gummielastische Lagerung des Trieb  aggregates, das ist des Motors mit dem Ge  triebe, bezweckt die Verhinderung der     über-          tragu.ng    der     Vibrationen    vom Motor in den.       Llufbatl    des Fahrzeuges.

   Ist jedoch das Trieb  aggregat mit den     Triebrädern    so verbunden,  dass in dasselbe auch die Reaktionen der auf  die Triebräder einwirkenden Kräfte geleitet  werden, wie dies beim Triebaggregat mit       Schwinghalbachsen    der Fall ist, so sollte die  Motorlagerung die Bedingung erfüllen, dass  dieselbe ein freie Motorbewegung ungefähr  um eine durch den     Schwerpunkt    des     Trieb-          -regates    hindurchgehende Achse zulässt und  <B>z</B> agrD<B>-</B>  dabei     sämtliche    Reaktionen von den auf die  Triebräder des Fahrzeuges einwirkenden Kräf  ten aufnimmt.  



  Die gummielastische Lagerung soll in     die-          qem    Falle keine grösseren     Verformungen,     weder in der Querachse noch in der Längsrich  tung des Triebaggregates, gestatten, da diesel  ben eine schlechte Führung der Triebräder.  schlechten Halt und übermässigen Verschleiss  der Gummireifen zur Folge hätten; anderseits  soll die Lagerung in Anbetracht der guten Ab  dämpfung der Motorvibrationen wesentliche  Verformungen um die Schwingungsachse er  möglichen.  



  Die bisher bekannten Lagerungseinrichtun  gen, welche diesen Bedingungen Rechnung    tragen sollen, sind so ausgeführt, dass Gummi  klötze im gegabelten Rahmen oder im Mittel  träger des Fussbodens abgestützt sind. Ein sol  cher Gabelträger ist entweder kostspielig und  schwer oder weist stets eine gewisse Elasti  zität in der Querrichtung auf, welche die  Räderführung ungünstig beeinflusst.  



  Gemäss der vorliegenden Erfindung ist das  Triebaggregat in zwei gummielastischen Rin  gen gelagert, von denen der eine direkt     in     einer Querwand des Aufbaues abgestützt ist:  Diese Einrichtung bietet ausser der Möglich  keit einer richtigen Lagerung nach den vor  stehend angeführten Grundsätzen noch den       -wesentlichen    Vorteil, dass sie die Zusammen  drängung auf einen minimalen Raum erlaubt.  



  Ein Ausführungsbeispiel der Erfindung  ist in der beiliegenden Zeichnung schematisch  veranschaulicht, wobei     Fig.    1 eine Vorder  ansicht der. Lagerungseinrichtung und     Fig.    2  einen Längsschnitt in der Achsebene des Trieb  aggregates zeigt.  



  Das Triebaggregat besteht aus dem Motor  1 und dem     Hinterachsgetriebe    2, welches die  Kupplung, das Wechselgetriebe sowie das       Kegelräder-Differential    umfasst. Der Antrieb  der     Schssrznghalbachsen    3 erfolgt in der üb  lichen Weise vermittels Gelenke und die  Schub- und Bremskräfte werden gleichfalls  in an sieh bekannter Weise aufgenommen, z. B.      durch Stützen. Das ganze     Triebaggmegat    ist  mittels einer Blechverkleidung in zwei     gumuii-          elastischen    Ringen gelagert, wobei einer dieser  Ringe im Bereich des Schwerpunktes T des  Aggregates angebracht ist, z. B. am Kupp  lungsgehäuse 22, welches derselbe am ganzen  Umfang umschliesst.  



  Das Vorderende des Triebaggregates ist in  einem gummielastischen Ring gelagert, wel  cher zum. Beispiel aus zwei Hälften 5 und 6  besteht, deren Teilebene durch die horizontale  Achse hindurchgeht. Die obere Hälfte 5 wird  vermittels eines Blechgehäuses unmittelbar in  der Karosserie gehalten, während die untere  Hälfte 6 mittels eines Joches 7 an die obere  Hälfte angeschraubt ist.

   Dieser Ring ist dazu  bestimmt, hauptsächlich die Reaktionen der  Schubkräfte     S1    und der Bremskräfte     S2    sowie  auch die Komponente vom Aggregatgewicht G       aufzunehmen.    Die auf die Achse bei der Fahrt  in Kehren wirkenden Querkräfte S3, die Reak  tionen von den auf die Räder 21 des Kraft  fahrzeuges wirkenden lotrechten Kräften     S-1     und vom Aggregatgewicht G werden vom  grossen gummielastischen Ring aufgenommen,  der am ganzen Umfang das Kupplungsgehäuse  22 umschliesst, und zwar im Bereich des  Aggregatschwerpunktes T.

   Dieser Ring ist  ebenso wie der bereits früher erwähnte klei  nere Ring     aus    zwei Hälften 8 und 9 zusam  mengesetzt, von denen die obere Hälfte 8 un  mittelbar im Aufbau gehalten wird und die  untere Hälfte 9 mit Hilfe eines Joches 10 an  die obere Hälfte angeschraubt ist. Beide Ringe  sind derart angeordnet, dass die Verbindungs  linie     a    der Mittelpunkt b und c, um welche  sieh die Ringe     verformen,    durch den Schwer  punkt T des Triebaggregates hindurchgeht.

    Damit wird die Bedingung einer richtigen       Motorlagerung    erfüllt, so dass derselbe frei um    seine     Trägheitsachse    schwingen kann, wobei  derselbe mit den Kräften     S5    und     S6    beide  Ringe nur auf Schub beansprucht, in welcher  Richtung die Ringe sehr weich sind. Der vor  dere Ring wird von der Wand 11 der frei  tragenden Karosserie getragen, während der  hintere Ring von der Wand 12 der Karosserie  getragen wird.

   Diese letztere Wand ist. mittels  der     durchgepressten        Versteifungsrippen   <B>13,</B>  14, 15 verstärkt, welche von den Befestigungs  schrauben 16 des Joches 10 zu den von den  Blechen 17, 18 und Unterzügen 20 ausge  bildeten festen Knoten derart verlaufen, dass  alle auf den Ring einwirkenden Kräfte in  diese festen Punkte abgeleitet werden.  



  Obzwar sich die beschriebene Lagerungs  einrichtung auf ein Triebaggregat im Heckteil  eines Kraftfahrzeuges bezieht, lässt sie sieh  selbstverständlich auch auf ein Triebaggregat  an Kraftfahrzeugen mit. Frontantrieb sinn  gemäss anwenden.



      Device for the rubber-elastic mounting of the drive unit in the self-supporting structure of motor vehicles The rubber-elastic mounting of the drive unit, that is the engine with the transmission, aims to prevent the transmission of vibrations from the engine to the. Llufbatl of the vehicle.

   However, if the drive unit is connected to the drive wheels in such a way that the reactions of the forces acting on the drive wheels are also directed into it, as is the case with the drive unit with oscillating semi-axles, the motor mounting should meet the condition that it approximately allows free motor movement around an axis passing through the center of gravity of the drive unit and <B> z </B> agrD <B> - </B> thereby absorbing all reactions from the forces acting on the drive wheels of the vehicle.



  In this case, the rubber-elastic mounting should not permit any major deformations, either in the transverse axis or in the longitudinal direction of the drive unit, since the same causes poor guidance of the drive wheels. would result in poor grip and excessive wear on the rubber tires; on the other hand, bearing in mind the good damping of the engine vibrations from significant deformations about the axis of oscillation he possible.



  The previously known Lagerungseinrichtun conditions, which are to take account of these conditions, are designed so that rubber blocks are supported in the forked frame or in the middle carrier of the floor. Such a fork carriage is either expensive and heavy or always has a certain elasticity in the transverse direction, which adversely affects the wheel guidance.



  According to the present invention, the drive unit is mounted in two rubber-elastic rings, one of which is supported directly in a transverse wall of the structure: In addition to the possibility of correct storage according to the above principles, this device also offers the essential advantage that it allows the crowding into a minimal space.



  An embodiment of the invention is illustrated schematically in the accompanying drawings, wherein Fig. 1 is a front view of the. Storage device and Fig. 2 shows a longitudinal section in the axial plane of the drive unit.



  The drive unit consists of the engine 1 and the rear axle drive 2, which includes the clutch, the change gear and the bevel gear differential. The drive of the Schssrznghalbachsen 3 takes place in the usual union manner by means of joints and the thrust and braking forces are also recorded in a manner known per se, for. B. by supports. The whole Triebaggmegat is supported by a sheet metal cladding in two gumuii- elastic rings, one of these rings is attached in the area of the center of gravity T of the unit, for. B. on the hitch housing 22, which encloses the same around the entire circumference.



  The front end of the drive unit is mounted in a rubber elastic ring, wel cher for. Example consists of two halves 5 and 6, the partial plane of which passes through the horizontal axis. The upper half 5 is held directly in the body by means of a sheet metal housing, while the lower half 6 is screwed to the upper half by means of a yoke 7.

   This ring is intended mainly to absorb the reactions of the thrust forces S1 and the braking forces S2 as well as the component of the unit weight G. The transverse forces S3 acting on the axle when driving in bends, the reactions from the vertical forces S-1 acting on the wheels 21 of the motor vehicle and from the unit weight G are absorbed by the large rubber-elastic ring that encloses the clutch housing 22 around the entire circumference , in the area of the aggregate center of gravity T.

   This ring is just like the earlier mentioned klein nere ring of two halves 8 and 9 put together, of which the upper half 8 is held indirectly in the structure and the lower half 9 is screwed with the help of a yoke 10 to the upper half. Both rings are arranged in such a way that the connecting line a, the center point b and c, around which the rings deform, passes through the center of gravity T of the drive unit.

    This fulfills the condition of a correct motor mounting, so that it can swing freely around its axis of inertia, with the forces S5 and S6 only loading both rings in thrust, in which direction the rings are very soft. The front ring is carried by the wall 11 of the cantilever body, while the rear ring is carried by the wall 12 of the body.

   This latter wall is. reinforced by means of the pressed-through stiffening ribs <B> 13, </B> 14, 15, which extend from the fastening screws 16 of the yoke 10 to the fixed nodes formed by the sheets 17, 18 and beams 20 in such a way that all of them run on the ring forces acting on these fixed points can be derived.



  Although the storage device described relates to a drive unit in the rear part of a motor vehicle, it naturally also includes a drive unit on motor vehicles. Use front-wheel drive accordingly.
