Abstract

Wheel suspension for a vehicle (7), with a carrier element (5), with a wheel carrier (1), which is arranged at a spaced location from the carrier element (5) and which is pivotable about a steering axis (30), with a wheel (14) mounted rotatably on the wheel carrier (1), with a steering wheel (58), which is mounted rotatably on the carrier element (5) at least indirectly and by means of which the wheel carrier (1) is pivotable about the steering axis (30), with at least one joint (8), which is connected to the wheel carrier (1) and which has a housing (26), a pivot pin (25) mounted pivotably in same and an angle-measuring device with a magnet (27) and with a magnetic field-sensitive sensor assembly unit (28), and with at least one guide means (2), via which the joint (8) is connected to the carrier element (5). A deflection (ω) of the pivot pin (25) relative to the housing (26) can be determined by means of the angle-measuring device in at least two different directions in space, and the magnetization (M) of the magnet (27) is oriented such that it extends at right angles to the steering axis (30).
