Definitions

  • the invention relates to a damper bearing for supporting a shock absorber or strut on a vehicle body, comprising a housing having a recess between a first housing part and a second housing part, and having a received in the recess elastic bearing for supporting a damper rod, wherein the housing parts made of a thermoplastic material and are materially interconnected. Furthermore, the invention relates to a method for producing such a damper bearing.
  • Damper bearings also referred to as suspension strut mount, attach the shock absorber or strut to the body of a vehicle.

  • These include, in particular, an end stop or an additional spring, a bearing for the suspension spring, possibly a dust protection sleeve as well as a pivot bearing on McPherson axles.
  • a ball or sliding bearing is necessary, which allows a rotation of the suspension spring about the shock absorber axis relative to the housing of the damper bearing or the body to allow steering movements of the axle.
  • the housing of the damper bearing should be as light and inexpensive, but at the same time stiff in the vehicle vertical direction, small in height and corrosion resistant.
