A steering triangle (1) is provided for the axle suspension of motor vehicles for the articulated connection of a vehicle axle with a vehicle chassis with two control arms (2, 3). The control arms are connected to each other in a joint housing (6) formed by the control arms (2, 3) together for a rubber-metal bearing (11) for fixing the steering triangle (1) on the vehicle axle. The rubber-metal bearing (11) has a pivot axis (12) provided with a spherical surface and an elastomer body (14), which extends around the pivot axis (12) at least in the area of the spherical surface and which is accommodated in a recess (16) located within the joint housing (6), in which steering triangle two pressing rings (17, 18) are arranged within the recess (16) of the joint housing (6) on the axial outer sides of the elastomer body (14). The pressing rings can be moved toward each other by a tensioning device via the intermediary of stop faces (22) of the joint housing (6). The stop faces are in contact with the outer sides of the pressing rings (17, 18), which outer sides face away from each other. The rubber-metal bearing can be pretensioned both in the axial direction and in the radial direction, so that stronger forces can be absorbed due to the higher rigidity achieved as a result.
