Abstract

The present invention relates to a pivot bearing, in particular on a swivel joint between a front wheel and a rear wheel of an articulated bus, which includes a cylindrical articulated bus (4) composed of a inner pipe (7), a outer pipe (8), a composition rubber layer (10) between them and a contain cover (3), the inner pipe mounted on the a bearing pin (2) with anti-torsion function, the outer pipe provided with a longitudinal seam (9).The pre-tightening articulated bus (4) inserts in the contain cover (3).According to the invention, an elastomer metal bushings (5, 6) are arranged at both end of the pre-tightening articulated bus (4) and are spaced slightly from it.The elastomer metal bushings includes a inner pipe (13) which has a interrupted elastomer layer case (16, 17) clinging and crossing the free-space (14, 15) at individual radial direction relative place, and inserting into the contain cover (3) with pre-tightening inside of the elastomer layer case (16, 17) under assembling condition, wherein the inner pipe (13) is mounted on the a bearing pin (2) with anti-torsion function, and the elastomer layer shells lies in a common longitudinal plane.

Description

technical field

[0001] The invention relates to a joint bearing according to the preamble of claim 1, in particular at a swivel joint between a front body and a rear body of an articulated passenger vehicle. Background technique

[0002] A known joint bearing of the same type (DE-PS 2337872) has a cylindrical joint sleeve consisting of an inner tube, an outer tube and at least one adhesively mounted joint between them. The synthetic rubber layer is formed, and the inner tube is fitted as a first bearing part in a rotationally fixed manner on a bearing pin. The outer tube has a longitudinal slot, which projects into the elastomer layer by its slot depth. In addition, the joint bearing comprises a receiving sleeve on the second bearing part, the joint sleeve, with its larger diameter in the unloaded state, is radially prestressed by reducing the diameter. Insertion into the receiving sleeve results in a longitudinal seam closure of a corresponding seam width in the unloaded ...
