Abstract

The two rear wheels are mounted at the ends of trailing arms pivoted in transverse bearings on the chassis. The trailing arms are joined by a cross bar such as a stabiliser. In order to accommodate tolerances in the cross bar, and to allow some relative lateral movement of the trailing arms, one end of the cross bar is mounted inside a long sleeve fitted to that trailing arm. The sleeve bearing contains locating bearings for the cross bar to allow some axial movement as well as radial springing, this being achieved by resilient bushings clamped between rigid side plates.

KraftwagenhinterachseMotor vehicle rear axle

Die Erfindung bezieht sich auf eine Kraftwagenhinterachse, bei der die Achszapfen der beiden Hader an je einem starren*, an der Karosserie schwenkbar gelagerten Kurbelarm befestigt sind, die nach P 21 03 399.8-21 durch eine biegesteife Querstrebe miteinander verbunden sind, wobei die Querstrebe zwischen den Lagerschaien der Kurbelarme und den Achszapfen angeordnet ist* Eine solche Hinterachse weist mit geringem baulichen Aufwand viele gute Eigenschaften auf. Es läßt sich aber nicht jede Wirkung der Querstrebe als Stabilisatormit_ einer ausreichenden Biegesteifigkeit vereinen.The invention relates to a motor vehicle rear axle, in which the axle journals of the two strikes are each attached to a rigid *, attached to the body pivoted crank arm which are connected to each other by a rigid cross strut according to P 21 03 399.8-21, the cross strut being arranged between the bearing rails of the crank arms and the axle journals Effort has many good properties. It can be but not every effect of the cross brace as a stabilizer with combine a sufficient bending stiffness.

Für einen solchen lall schafft die Erfindung dadurch Abhilfe, daß die Querstrebe in mindestens einem Kurbelarm drehbar gelagert ist. So hat diese Achse die Vorteile der Längslenker-- und der Schräglenkerachse und die Neigung des Wagenkastens bei der Kurvenfahrt, die Verteilung der Achslast auf die Räder und davon abhängig das Eigenlenkverhalten der Hinterachse nicht von den Abmessungen der Querstrebe beeinflußt..The invention provides a remedy for such a lall, that the cross strut is rotatably mounted in at least one crank arm is. So this axle has the advantages of the trailing arm - and the trailing arm axle and the inclination of the car body cornering, the distribution of the axle load on the wheels and the self-steering behavior of the rear axle depends on this not affected by the dimensions of the cross brace.

Weiter ergibt sich ein Vorteil beim Zusammenbau, weil die beiden gegeneinander verdrehbaren und in Richtung , ihrer gemeinsamen Mittelachse verschiebbaren Längslenker auch in Richtung der Querstrebe auftretende Toleranzen zwischen den beiden Lagern am Wagenkasten ausgleichen. There is also an advantage in assembly because the two mutually rotatable and displaceable trailing arm in the direction of their common central axis also compensate for tolerances occurring in the direction of the cross brace between the two bearings on the car body.

In dem einen Kurbelarm kann ein Führungsrohr angeordnet sein, das das Lager für die Querstrebe trägt.A guide tube can be arranged in one crank arm be that carries the bearing for the cross brace.

Die Zeichnung zeigt ein Ausführun^beispiel der Erfindung,The drawing shows an embodiment of the invention,

Die Lager 2 und 3 sind mit Bolzen 31 an konsolen des Wagenkastens befestigt. Vom Lager 2 wird der Kurbelarm 9 getragen, in dein ein Führungsrohr 28 angeordnet ist, v. el dies die Lager 29 und 30 für die Querstrebe 12 trägt. Die Querstrebe 12 ist im Kurbelarm 10 befestigt, der seinerseits über ein Lager und einen Bolzen 31 an dem Wagenkasten befestigt ist.The bearings 2 and 3 are with bolts 31 on consoles of the car body attached. The crank arm 9 is carried by the bearing 2, in which a guide tube 28 is arranged, v. el this the camp 29 and 30 for the cross strut 12 carries. The cross brace 12 is fastened in the crank arm 10, which in turn is fastened to the car body via a bearing and a bolt 31.

Beim Durchfedern machen die Rader 7 und 8 die gleichen Bewegungen wie bei der Achse, bei der die Querstrebe 12.als
Verdrehachse ausgebildet ist. Beim ungleichseitigen Durchfedern der Kader 7, 8 dreht sich die Querstrebe 12 im Rohr 28, sodaß die Wirkung der Querstrebe 12 als Stabilisator
