Abstract
In a method of producing a chassis control arm, at least one end of a blank is provided with at least two webs which are arranged in spaced-apart relation and define a clearance there between. Each of the webs is formed with a bearing opening, with the bearing opening of one web and the bearing opening of the other web aligned in coaxial relation to provide a bearing zone. A bearing sleeve is placed into the bearing openings, and the bearing sleeve is peripherally expanded at least in one region such as to project radially into the clearance. The at least one peripheral expansion can be formed to directly abut at least one of the webs in an axial direction.
Claims22
A method of producing a chassis control arm, comprising the steps of:
- providing an end of a blank with at least two webs in spaced-apart relation to define a clearance there between;
- forming each of the webs with a bearing opening, with the bearing opening of one web and the bearing opening of the other web aligned in coaxial relation to provide a bearing zone;
- placing a bearing sleeve into the bearing openings;
- and
- peripherally expanding at least one region of the bearing sleeve to form at least one peripheral expansion sized to project radially into the clearance.
A chassis control arm, comprising:
- a bearing zone having at least two webs in spaced-apart relation to define a clearance there between, each of the webs having a bearing opening, with the bearing opening of one web and the bearing opening of the other web aligned in coaxial relation;
- and
- a bearing sleeve received in the bearing openings and having at least one region which is peripherally expanded so as to project radially into the clearance.
A vehicle, comprising a chassis control arm including a bearing zone having at least two webs in spaced-apart relation to define a clearance there between, each of the webs having a bearing opening, with the bearing opening of one web and the bearing opening of the other web aligned in coaxial relation;
- and a bearing sleeve received in the bearing openings and having at least one region which is peripherally expanded so as to project radially into the clearance.
