Embodiment Construction

[0025] figure 1 The shown torsion beam rear axle 1 comprises two trailing arms 2 extending mainly in the longitudinal direction of the vehicle, which are connected by means of a cross member 3 . The transverse beam 3 is designed in a known manner to be bending-resistant, but twistable. A wheel carrier for supporting the rear wheels 4 of the vehicle is situated on the rear end section of each trailing arm 2 . Furthermore, each trailing arm 2 is coupled at the front end to the vehicle structure 6 by means of an axle guide bearing 5 .

[0026] In the exemplary embodiment shown, the pivot axis A of the axle guide bearing 5 extends horizontally and transversely to the longitudinal or forward direction V of the vehicle. Starting from this orientation, however, a deviation of the order of magnitude of a maximum of 25° is possible both with respect to the horizontal direction and with respect to the adjustment angle to the longitudinal direction of the vehicle.

Abstract

An axle guide bearing for coupling a rear axle to a vehicle structure of a motor vehicle, said axle guide bearing comprising an outer sleeve (7) for coupling to said rear axle, and for An inner part (8) fixedly arranged on the vehicle structure, which is inserted into the outer sleeve (7) via a pin (14) and which has a stop disc (15), said stop disc (15) is axially spaced from the axial end section (12) of the outer sleeve (7), and is used to support the first rubber body (9) of axial force, so The first rubber body (9) is arranged between the axial end section (12) of the outer sleeve (7) and the stop disc (15), and the second rubber body (10), so The second rubber body (10) is arranged between the pin (14) and the outer sleeve (7). A first liquid-filled chamber (16) and a second liquid-filled chamber (17) are provided on the second rubber body (10), wherein the first liquid-filled chamber (16) is relatively opposite to the motor vehicle The advance direction (V) of the pin is arranged in front of the pin (14) and the second liquid-filled chamber (17) is arranged behind the pin (14). A first stop body (19) is arranged in said first liquid-filled chamber (16), said first stop body (19) restricting the Maximum support stroke (s1) of the axle guide bearing. Arranged in the second liquid-filled chamber (17) is a second stop body (20), which limits the Maximum support travel (s2) of the axle guide bearing. A vibration-damping axle guide bearing for a torsion beam axle is thus provided.

Description

technical field [0001] The invention relates to an axle guide bearing or axle guide bracket for coupling a rear axle to a vehicle structure of a motor vehicle. Here, the invention also relates to a torsion beam rear axle or composite guide rear axle with such an axle guide bearing. Background technique [0002] In passenger cars, torsion beam axles or composite guide axles are also understood here in another sense as semi-independent suspensions or coupled drive axles, which are widely used due to their simple construction and better functionality. rear bridge. [0003] Usually, the torsion beam axle comprises two trailing rods extending more or less in the longitudinal direction of the vehicle, which are pivotally coupled to the vehicle structure via a front end section, and also include a bending-resistant shaft connected to the trailing rods. , but twistable beams. Wheels are respectively mounted on the rear end sections of the trailing arms. [0004] The pivotable co...
