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.

Method of producing a chassis control arm, and control arm for a vehicle

The invention relates to a subframe for the vehicle chassis of motor vehicles, which subframe has at least one cavity usable as a pressure accumulator and has a cross member () which is connected, at the two end faces () thereof, to a node element (). Bearing elements (to) and/or further frame elements are attached to the node elements (). The cross member () is formed as a continuous rib-reinforced component or extruded part () and forms for the pressure accumulator a pressure-resistant cavity which is closed off by the node elements () at the end faces.

Subframe with integrated pneumatic or hydraulic liquid vessel for the vehicle chassis of motor vehicles

The invention relates to a method for damping vibrations on chassis bearings of motor vehicles, and a device for implementing the process. A process and a device are to be presented with which outstanding vibration damping and vibration isolation and noise insulation can be achieved over a wide frequency range with consideration of the driving states and roadway conditions which occur in motor vehicles. For this purpose it is proposed that the driving state of the motor vehicle and/or the roadway conditions are detected by way of sensors and that the at least one chassis bearing is modified to different characteristics to change its stiffness and/or damping depending on the detected parameters. The device is formed with sensors for detecting the driving state of the motor vehicle and for roadway conditions, with an electronic control device for processing the acquired signals and for selection of various controllable characteristics and at least one chassis bearing, the stiffness and/or damping of which can be modified.
