1. A bearing for a control arm of a wheel suspension of a vehicle, the bearing comprising:
- a bearing structure including an inner and outer ring with a rubber ring arranged between said inner and outer ring to form a rubber bearing, said bearing structure having a magnet pole ring; and
a sensor arranged in or at the bearing structure for determining a relative movement of vehicle parts connected to each other by the bearing structure, said sensor being spaced by a radial distance from a center axis of said outer ring, a magnetic field of said magmatic pole ring is detected by said sensor or by a magnetic field sensor portion of said sensor.
