Problems solved by technology

Here, for reasons of rigidity and strength, the diameter of the ring formed by the (mostly three) fastening screws has to be selected relatively large, which can be disadvantageous due to the spatial construction requirements

Embodiment Construction

[0016] first refer to attached figure 1 , 2a , only the support seat 10 for the piston rod of the common shock absorber in the wheel suspension of the double-track vehicle is shown in said accompanying drawing, but the above-mentioned piston rod is not shown, and the piston rod is shown along the The longitudinal axis L runs in the direction and is, as usual, the axis of symmetry or axis of rotation of an approximately rotationally symmetrical bearing 10 via which the piston rod is supported or mounted or fastened to the body structure 2 of the vehicle. For this purpose, the body structure 2 , shown only very incompletely, is generally designed, for example, as a so-called strut cap and has a circular through-opening 3 , in which is arranged a valve, identified as a whole by the reference numeral 10 . The bearing seat for the shock absorber.

[0017] The components of the bearing 10 are in particular the bearing flange 11, the basically usual bearing cover 12* and here also th...

Abstract

The invention relates to a support bearing (10) of a vibration damper (1) in the wheel suspension of a vehicle with a support bearing flange (11) supported and force-fittingly attached on a body structure (2) of the vehicle, said support bearing flange engaging around an annular elastomer element (13a) in which the damper piston rod (1a) is suspended. With an annular collar (11b) which forms a hollow cylinder and the cylinder axis of which is at least approximately coincident with the longitudinal axis (L) of the vibration damper (1), the support bearing flange (11) penetrates a through-opening (3) in the body structure (2) so far that a nut (120) or a support bearing cover designed as a union nut is screwed on a thread (G) provided on the outer wall of said collar (11b). With a clamping aid element (16) interposed, said nut or support bearing cover draws the support bearing flange (11) towards the body structure (2) in a manner supported on the body structure (2), such that a peripheral ring section (2a) of the body structure (2), said peripheral ring section surrounding the through-opening (3), is clamped between the support bearing flange (11) and the clamping aid element (16) and ultimately the nut (120) or the support bearing cover. As an alternative to the clamping aid element (16) or in addition to same, the collar (11b) has a shape that increases its elasticity in the direction of the longitudinal axis (L) of the thread (G).

Description

technical field [0001] The invention relates to a bearing bracket for a shock absorber or a shock absorber spring unit in a wheel suspension of a vehicle according to the preamble of claim 1 , having a bearing mounted on and non-positively fastened to the body of the vehicle A structural bearing flange which encloses an adjoining ring-shaped elastomer element in which the element of the shock absorber, and in particular its piston rod, is suspended. For the prior art, in addition to DE 102014218800A, DE 102008010541A1 and DE 102012002806A1 see in particular DE19719301A1. Background technique [0002] Basically, as is widely known and also shown in said document, the shock absorber bearing is non-positively connected to the vehicle body by means of mostly several (for example three) threaded parts, which ring around the damper. The vibrator clamps the so-called bearing flange against the contact surface of the vehicle body structure distributed along the longitudinal axis. ...
