Method for Producing a Chassis Link
First Claim
1. A method for producing a chassis link, comprising the steps of:
- shaping a single-shell main body from a sheet metal blank, thereby forming bearing regions on the main body for attaching bearing elements by which the main body is connected to a bodywork part or a crossmember and to a movable part of a wheel suspension of a motor vehicle, the bearing regions comprising a wheel-side bearing region and two bodywork-side or crossmember-side bearing regions, the main body comprising two arms which merge into one another and define a main-body plane and a concave edge region of the main body, the concave edge region extending from the wheel-side bearing region up to a first of the two bodywork-side or crossmember-side bearing regions and being angled relative to the main-body plane, the second bodywork-side or crossmember-side bearing region is formed as a projection and provided with a bush, and the projection and the arm, which comprises the first bodywork-side or crossmember-side bearing region, define an indentation, along which the main body is angled relative to the main-body plane; and
deforming the sheet metal blank by deep drawing, wherein the deep drawing includes pre-drawing during which the indentation is produced and in which the indentation is trimmed and the bush is attached to the projection once the indentation has been trimmed,wherein the sheet metal blank is pre-drawn such that the indentation is given a radius that matches the bush to be attached such that there is no further need for a further forming operation in the indentation once the indentation has been trimmed.

Abstract
A method for producing a chassis link includes shaping a single-shell main body from a sheet metal blank and deforming the sheet metal blank by deep drawing, which includes pre-drawing during which an indentation is produced on the main body and in which the indentation is trimmed and a bush is attached to a projection on the main body once the indentation has been trimmed. The sheet metal blank is pre-drawn such that the indentation is given a radius that matches the bush to be attached such that there is no further need for a further forming operation on the indentation once the indentation has been trimmed.
