Problems solved by technology

But the disadvantage of this two-piece chassis control arm structure is that it can only be produced at great cost, because the two halves must be machined separately and then joined.

Embodiment Construction

[0030] according to figure 1 , figure 2 and image 3A first embodiment of a chassis control arm 1 for a vehicle has a control arm body 2 with two spaced apart opposite side walls 3 which are integrally connected to each other on the longitudinal sides and On their opposite free longitudinal sides 4 , they are connected to one another by means of joining structures 5 . The joining connection 5 is represented in the exemplary embodiment by a partial welded connection 5 a. The control arm body 2 is produced from sheet metal by forming it about its axis of symmetry S using bending technology. On the axial ends of the control arm body 2 , coaxial bearing holes 6 are machined into the side walls 3 , which are respectively used to receive rubber-metal bearings 7 . The torsional rigidity of the control arm body 2 is greater than the gimbal stiffness of each individual rubber-metal bearing 7 due to the jointed connection 5 , and is lower without the jointed joint 5 .

Abstract

A chassis suspension arm (1) for a vehicle, having an elongate suspension arm body (2) consisting of a single-piece metal plate which is deformed by bending in such a manner that said suspension arm body forms two side walls (3) which are opposite each other at a distance, wherein the side walls (3) are connected to each other at least in sections on the free longitudinal sides (4) thereof by a joining connection (5), and the axial ends of said suspension arm body each have at least two bearing openings (6) arranged coaxially with respect to each other, and at least one rubber / metal bearing (7) which is insertable into the coaxial bearing openings (6), wherein the cardanic rigidity of at least one of the rubber / metal bearings (7) is lower than the torsional rigidity of the suspension arm body (2).

Description

technical field [0001] The invention relates to a chassis control arm for a vehicle having an elongated control arm body made of a single piece of sheet metal and at least one rubber-metal support, the control arm body being bent in such a way Technical molding, so that the control arm body forms two mutually spaced opposite side walls, wherein the side walls are at least partially connected to each other on their free longitudinal sides by connecting structures / connections of joint technology, and the control arm The axial ends of the body respectively have at least two bearing holes arranged coaxially with each other, and the rubber-metal bearings can be installed in the coaxial bearing holes. The invention also relates to a method for manufacturing such a chassis control arm method. Background technique [0002] Such chassis control arms are used in the wheel suspensions of vehicles, where they control the wheels relative to the vehicle structure with limited degrees of ...
