Problems solved by technology

However, the locking ring has the disadvantage that, due to its rectangular cross-section, a tilting moment acts on it when axially loaded, which can cause the locking ring to disengage from the groove formed in the inner peripheral surface of the housing
Such a tilting moment leads at least to a constant axial displacement of the locking ring, so that fatigue fractures can occur in the support ring in contact with the locking ring
A further disadvantage of the locking ring is that its circumference covers an angle of only about 270°, which can also cause a risk of detachment

Embodiment Construction

[0035] Figure 11 A lateral cross-sectional view of a conventional elastomer hinge 1 is shown. The elastomeric hinge 1 has a housing 12 with a through opening 14 which extends axially along a longitudinal axis 16 of the elastomeric hinge 10 . A hinge pin 18 extends through the through-opening 14 or is accommodated therein. An elastomer body 20 is fastened to the outer circumference of the hinge pin 18 , with its outer circumference resting against the inner circumference of the housing 12 in the central region of the elastomer hinge 1 . The elastomer body 20 can be fixed on the hinge journal 18 or on the inner peripheral surface of the housing 12 by vulcanization, adhesive bonding or the like. By means of the elastomer body 20 , a rotational movement and / or a universal movement of the hinge pin 18 relative to the housing 12 about the longitudinal axis 16 (ie in the path of a tilting movement about the longitudinal axis 16 ) is possible.

Abstract

The invention relates to an elastomeric joint (10), having a housing (12) with a through opening (14) which extends axially along the longitudinal axis (16) of the elastomeric joint, a pivot (18) which extends through the through opening (14) of the housing (12), an elastomer body (20) which is fastened to the pivot (18) and is arranged radially between the pivot (18) and the housing (12), and with at least one supporting ring (22) which is fastened to the elastomer body (20) on one end side of the through opening (14), wherein a wire ring (32) locks the supporting ring (22) with respect to the housing (12), with the result that the pivot (18) is held in the housing (12) in an axially secured manner.

Description

technical field [0001] The invention relates to an elastomer hinge according to the preamble of claim 1 , in particular an elastomer hinge for a chassis part of a motor vehicle. Background technique [0002] Elastomer hinges are maintenance-free and insensitive to external environmental influences and are used in particular in vehicle construction for precise axle guidance and for increasing driving comfort. In such an elastomer hinge, the elastic elastomer body is prestressed in the axial direction, whereby an adjustable radial spring characteristic results. [0003] DE 37 15 360 C2 discloses an elastomer hinge of the same type, in which a sleeve-shaped elastomer body is pretensioned between two support rings. A material recess is provided in the central region on the inner circumference of the cylindrical housing, so that a space is formed into which the elastomer body can be deflected. As a result, the pretension of the elastomer body is reduced in this region, resultin...
