Problems solved by technology

For example, large angles of rotation of the articulation axes involved in ball joints with respect to the housing can be problematic, especially where radially acting forces are involved, since there is a risk of warping the inner walls of the housing or bearing cage. The elastic layer of the rubber torn, causing wear at this point and long-term deterioration of joint performance

Embodiment Construction

[0034] figure 1 The cross-section of a vehicle 10 (for example a truck or off-road vehicle) shown in , comprises two swing arms 2 , 3 which form an acute angle in a triangular suspension arm arrangement and extend in a V-shape relative to one another in plan view. At the apex of the triangle formed in this way, the swing arm is engaged with the axle 11 (here the rear axle) by means of the articulation 1 . The axle is enlarged in a central region with respect to the transverse direction from the vehicle to accommodate the differential. Thus, the articulation device 1 can be fitted at the upper end of said area 9 of the rear axle 11 enlarged to accommodate the differential, thereby constituting a transverse guide and a longitudinal guide for the axle 11 . The two pivoting arms 2 , 3 for support here can be connected in their upper regions 2 a , 3 a to, for example, longitudinal frame parts for load bearing. A similar articulation device 1 can also be used here.

Abstract

A joint assembly (1) with a joint ball (4) through which an axle body (12; 112; 212; 312) extends. The joint ball (4) is mounted in and able to rotate relative to a housing (5) that at least partially surrounds the joint ball (4) and / or one or more support rings (6) with a rubber-elastic intermediate layer (7). The joint assembly (1) is designed so that the axle body (12; 112; 212; 312) can rotate within the joint ball (4).

Description

technical field [0001] The invention relates to a motor vehicle according to the preamble of claim 1 having at least one articulation and / or bearing arrangement in which a spherical living The joint is mounted rotatably relative to the housing surrounding the joint ball via a rubber-elastic spacer; the invention also relates to a joint according to the preamble of claim 22 . Background technique [0002] As is known, articulations are constructed in such a way that the ball joint movably supported in the housing cannot slide relative to the joint housing which accommodates it, for example made of plastic, and between the ball joint and the shell There is a gasket with rubber elasticity between the bodies. This spacer provides good comfort both in terms of shock absorption and in terms of preventing noise generation. For example, large angles of rotation of the articulation axes involved in ball joints with respect to the housing can be problematic, especially where radiall...
