Abstract

Suspension linkage assembly (1) comprising a suspension link (2) which has at least one bearing receptacle (2a) for a link bearing (5), a cover (3) formed separately from the suspension link (2) and, when installed, at least part of the underside of the suspension link (2) covers, and a separately to the suspension arm (2) formed bump stop (4) whose spatial shape of the outer contour of the arm bearing (5) is adapted and at least partially applied in the installed state of the arm bearing (5) and wherein the cover (3 ) and the stop buffer (4) in the non-installed state formed separately from each other and in the installed state, the cover (3) in turn is firmly connected to the chassis link (2), the stop buffer (4) in turn is firmly connected to the link bearing (5) and the cover (3) and the stop buffer (4) are interconnected.

Description

The present invention relates to a suspension link assembly according to the preamble of claim 1.

Such suspension control arrangements are used in vehicle construction and are characterized by covers on the suspension arm, also called wishbone or simply handlebar, in order to achieve, inter alia, a better flow around the underbody in the suspension and to ensure protection against stone chips. The suspension connects the wheel with the body and carries it under certain degrees of freedom. Suspension links can be produced from formed (steel) sheets or from (formed) extruded sections, for example an extruded aluminum section. The suspension link has terminal bearing mounts, in which a preferably constructed as a rubber-metal bearing arm bearing can be used. The bearing mounts can be formed depending on the embodiment of two concentric holes in two parallel side bars of the suspension arm or from a guide sleeve into which the formed as a rubber-metal sleeve bearing arm bearing is pressed, and depending on the design of the suspension arm is welded to this or is held in one or more holes in the side bars of the suspension arm or is integrally formed by a forming process of the material of the suspension arm. Depending on the selected handlebar geometry, the wheel-side handlebar mount in the installed state can represent the lowest point. When driving over obstacles there is a risk that the bearing seat hits the ground and thus the bearing seat and / or the arm bearing is damaged.

The generic DE 10 2014 003 305 A1 shows a cover for a suspension arm, which has at least one bearing support for a link bearing, wherein the cover formed separately to the control arm covers at least a portion of the underside of the suspension arm in the installed state, wherein on the cover serving as a buffer extension is arranged, extending from the Cover extends in the direction of the arm bearing and wherein the spatial shape of the extension of the outer contour of the arm bearing is adjusted and the extension is partially applied to the arm bearing.

Object of the present invention is to provide an alternative embodiment of a generic suspension control arm assembly.

This object is solved by the features of patent claim 1.

A suspension control arm assembly comprises a suspension arm, which has at least one bearing support for a link bearing, a separately formed for the control arm cover that covers at least a portion of the underside of the suspension arm when installed, and a separately formed to the suspension arm stop bumper whose spatial shape of the outer contour of the arm bearing is adapted and at least partially rests in the installed state of the link bearing and wherein the cover and the bump stop in the non-installed state separately formed and in the installed state, the cover in turn is firmly connected to the suspension arm, the bump stop is in turn firmly connected to the arm bearing and the cover and the stop buffer are interconnected.

By stop buffer and cover are initially formed separately from each other, these can be easily and quickly attached to complicated shaped suspension arms. If both elements are firmly connected to the control arm, then they are finally connected to each other. This results in a closed surface on the underside of the suspension arm and an improved stone chip protection.

In a preferred embodiment, the stop buffer and the cover are positively connected to each other. The positive connection is made in particular by a plug connection, so that the cover and the stop buffer can be particularly easily and quickly connected to each other.

In a preferred embodiment, the stop buffer is positively connected to the link bearing. The stop buffer encloses the handlebar bearing partially.

Further details and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings.

Show:

1 a suspension handlebar;

2 a suspension link assembly;

3 a section through the suspension control arm assembly;

4 a stop buffer.

According to the 1 is a suspension handlebar 2 Made of (aluminum) extruded section by forming and trimming. At one end is a camp recording 2a in the form of two coaxial openings in the side webs of the suspension arm 2 educated. The camp recording 2a holds a handlebar bearing 5 which is typically formed as a rubber-metal sleeve bearing.

The 2 and 3 each show a suspension control arm assembly 1 with a suspension handlebar 2 according to 1 , On the suspension handlebar 2 is an aerodynamically effective cover 3 arranged so that they in the illustrated installed state, the underside of the suspension control arm 2 covers in large part. The cover 3 as such, is stuck with the suspension handlebar 2 connected. An impact buffer 4 surrounds the handlebar bearing 5 partially positive fit, the bump stop 4 in its spatial shape the handlebar bearing 5 is adapted (see 4 ) that this on the handlebar bearing 5 is applied. The cover 3 and the stop buffer 4 are positively connected by a plug connection.
