Description

The invention relates to a bearing for the articulation of a chassis stabilizer on a motor vehicle with a rubber bearing body having at least two rubber bearing body parts for encompassing the stabilizer and a U- or Ω-shaped clamp made of a plastic material or a plastic composite material such as fiber-reinforced plastic for receiving the bearing body. with a rubber bearing body supporting the support wall, to which support tabs and with a support wall and the support tab against each supporting rib structure, wherein the clamp has a, through the support wall radially limited insertion receptacle for receiving a vehicle-side rubber storage body part, which includes the insertion receptacle corresponding Einschubflansche.

Such a generic type bearing is for example in the DE 10 2012 208 156 A1 described. By using a plastic retaining clip that provides an outboard rib structure as a reinforcing member for transmitting operating forces from the stabilizer to the body of the motor vehicle, weight reduction can be provided as compared to the otherwise-used metal bands, without the function of the bearing, particularly with respect to on the stiffness requirements, affecting.

As is known, suspension stabilizers on motor vehicles are used at least partially to cancel the differences in the force acting on the inside and outside of the curve when cornering. For this purpose, a stabilizer may serve in the form of a torsion bar, the two ends of which are connected to the wheel suspension of a wheel of the associated axle. To hold the stabilizer or the stabilizer bar on the body of the vehicle is the specified camp.

Depending on the embodiment, the rubber bearing body mounted in the clamp, which is also referred to as a retaining clip in the field, may be designed as a pure rubber body, such as an elastomer body. However, it can also be provided that the rubber bearing body comprises both rubber layers and layers of a hard material such as a plastic or metal for setting a predetermined identifier of the bearing. Such hard material layers, which are usually vulcanized in, are also referred to in the field as depositors.

The rubber bearing body conventionally comprises at least two rubber bearing body parts, which may be designed in particular as half shells. In this case, a vehicle facing away from the rubber bearing body part can be vulcanized into the clamp or the headband, so when mounting the bearing on the stabilizer, the vehicle-side rubber bearing body part is to be inserted alone in the insertion receptacle of the clamp, such that the Einschubflansche a vehicle-side rubber storage body part at least partially in extend the clamp into it. In particular, to facilitate the mounting of the stabilizer on the motor vehicle or the final assembly on the vehicle may be provided in the prior art, to attach the bearing parts in the manner of pre-assembly to the stabilizer or on the stabilizer bar. This describes the DE 698 04 170 T2 a metallic reinforcement, which is plastically deformed during assembly of the bearing on the stabilizer bar. The DE 10 2004 056 884 B4 on the other hand describes a bearing in which the vehicle-side rubber bearing body part in the region of its insertion flanges fastening elements which engage in associated, axially centrally located recesses on the clamp for holding the vehicle-side rubber bearing body part on the clamp.

The invention has for its object to further develop a generic type bearing so that also allows pre-assembly on the stabilizer, without significantly affecting the rigidity of the plastic clamp and thus the stability of the bearing.

The bearing according to the invention is characterized in that the support wall towards the bearing center axis at least two axially spaced and radially or approximately perpendicular from the inner circumferential surface of the support wall inwardly and circumferentially extending webs, which correspond with axial form-fitting portions of the insertion flanges of the vehicle-side rubber bearing body part to provide an axial positive connection between the clamp and the vehicle-side rubber bearing body part. The clamp of the bearing according to the invention further comprises two paired, approximately opposing fasteners and the insertion flanges of the vehicle side rubber bearing body part two paired, approximately opposing counter-elements, each in a releasable engagement with an associated fastener of the clamp can be brought to hold the on the vehicle side rubber bearing body part on the clamp.

With the specified design of the bearing according to the invention, despite the use of a plastic clamp for receiving the rubber bearing body and despite providing a kind of captive between clamp and fahrzeugseitigem Rubber bearing body part so that a light bearing are provided, which is designed for the transmission of high operating forces and in particular simplifies the pre-assembly of the bearing parts on the stabilizer.

It should be noted that the terms "radial" and "axial" used herein refer in particular to the center axis of the bearing or are to be understood as such. The term "radial" is to be understood broadly and means generally a direction perpendicular to the inner circumferential surface of the support wall and perpendicular to the center axis of the bearing, i. the bearing axis is.

Further advantageous and inventive features are given in the general description, the description of the figures, the drawings and the dependent claims.

Conveniently, it can be provided that the fastening elements of the clamp for releasably engaging with associated counter-elements on the vehicle-side rubber storage body part each one extending from a support tab of the clamp, extending parallel to the support wall and perpendicular to the axis, radially outwardly and elastically deflectable latch hooks. Appropriately, it can be provided that these elastically deflectable latching hooks are respectively arranged in the region of the end faces of the clamp, i. at the axial ends.

It can be provided that the latching hook is incorporated substantially directly into the support wall, in particular by a clearing radially outward to the inner circumferential surface of the support wall. The latching hooks may each comprise a latching nose, which extends radially inwardly over the inner circumferential surface of the support wall, such that in a deflection of the latching hook whose locking lug is covered by the support wall and insofar forms no undercut in the axial or radial direction with the vehicle-side bearing body part ,

The arrangement of the fastening elements in the region of the end face of the clamp has the advantage that the stiffness of the plastic clamp is not affected or only to a very small extent by this structural design. In addition, the elastically deflectable latching hooks, which may protrude beyond the inner surface of the support wall in the force-free state, at the same time serve to define the insertion receptacle for the vehicle-side rubber bearing body part.

To engage with the respective fastening element, the counter-elements of the vehicle-side rubber bearing body part may be formed as radially outwardly facing locking projections, said locking projections may extend from the respective insertion flange of the vehicle side rubber bearing body part. Advantageously, it may be provided that the latching projections, which may extend radially outwards complementary to the lugs of the latching hooks, be designed to be rigid in comparison to the latching hooks of the clamp, so that the latching projections each have a guide surface during insertion of the vehicle-side rubber storage body part into the insertion receptacle of the clamp provide for deflecting the associated latching hook.

A particularly advantageous embodiment of a bearing according to the invention is when the fasteners are arranged on the clamp, in particular the latching hooks in the same axial position as the at least two arranged on the support wall and axially spaced, and are arranged radially inwardly and circumferentially extending webs, so that the Latch hooks are aligned axially with the webs described and the plug-in receptacle is determined by said webs and the latching hooks together.

In order to provide sufficient installation space for a fastening means in the region of the support bottles despite the provision of the reinforcing rib structure, for example a head of a bolt which extends through a through hole in the respective support tab, the design of a particular rib structure has proven to be very advantageous. The rib structure may have a plurality of longitudinal ribs, each extending from one support tab to the other support tab and extending from the support wall and / or the support tabs and extending from these and free ends. In this case, each of the two axially adjacent, outer longitudinal ribs over its longitudinal extent predominantly spaced and extend parallel to each other and converge in the bearing flanges so that in the area of the support tab to the passage guide around a rib-free area is designed and still sufficient support of the support wall to the Support flanges is provided.

In a further development of the outgoing from the support wall or one or the support tabs rib structure may be provided that this has a central and parallel to the bearing axis extending transverse rib, which extends from the support wall and free ends and connects all longitudinal webs together. It can also be provided in the rib structure, an axially central and shortened in its longitudinal extent longitudinal rib, which ends before reaching the support tabs. This design measure again increases the installation space in the region of the support tabs, in particular for fastening means for fastening the clamp of the bearing according to the invention on the vehicle.
