摘要： The invention relates to a device for detecting a rotational angle of a rotatable part, preferably a steering wheel or steering column of a vehicle, comprising at least one magnet (10), at least one sensor (20, 22) that detects the magnetic field of the magnet (10), at least one housing (28) in which the sensor (20, 22) and/or the magnet (10) are arranged in such a way that they can be moved in relation to each other, at least one printed circuit board (26) which is electroconductively contacted by at least one connection element (42) of the sensor (20, 22). Said printed circuit board (26) comprises at least one interface or a plug (30) from which the output signal (21, 23) of the sensor (20, 22) or an output signal (54) derived therefrom is transmitted to an evaluation unit (60) which is located, preferably, at a distance from the housing (28), said evaluation unit determining the absolute position of the rotational angle according to the output signal (21, 23) of the sensor (20, 22).

摘要： The invention relates to an angle sensor (1) for determining a rotation angle of a rotatable body (5), such as, for example, a steering column in a motor vehicle, to a gear wheel (3) that can be used in said angle sensor and to a method that can be used to produce such a gear wheel. The orientation of a magnetic field generated by the gearwheel (3) is to be detected by a magnetic field sensor (6). According to the invention the entire gear wheel (3) shall consist of a magnetisable material, such as, for example, hard ferrite, into which a magnetisation is introduced, which is stronger in a central region (9) of the gear wheel (3) than in an edge region (10) in which the teeth are arranged. In order to magnetise the edge region (10) merely weakly, and hence to minimise a negative influence of the teeth on the homogeneity of the generated magnetic field, the front face of the gear wheel can be magnetized. In this connection the magnetisation process can advantageously take place at the same time as an injection moulding process to form the gearwheel (3).

摘要： The invention relates to a path sensor (1a; 1b; 1c) comprising at least one magnetoelectric transformer element (5) and a magnetic circuit with at least one flux conductor path (3, 4; 9, 10; 14, 15) and at least one magnet (2; 11). Said path sensor is smaller in size. The influence on magnetic flux caused by displacement of an object can be measured by the transformer element (5). The flux conductor path (3, 4; 9, 10; 14, 15) and the transformer element (5) are arranged in an unaltered position in relation to each other during the measuring of the path. Said parts (3, 4, 5; 9, 10; 14, 15) and the at least one magnet (2; 11) can be displaced relative to each other. Modification of the magnetic field which can be evaluated by the transformer element (5) is carried out by modifying the air gap (d) in the magnetic circuit during the displacement of the magnet (2; 11). The contour of the flux conductors parts (3, 4; 9, 10; 14, 15) of the magnetic circuit surround the path of the magnets (2, 11) in such a manner that modification of the width (d) of the air gaps in the course of the path (6; 12) results in a predetermined signal progression in the transformer element (5).

摘要： The invention relates to a measurement device (10) for the non-contact detection of an angle of rotation. Said device comprises a support plate (12) which consists of a magnetically non-conductive material and serves as rotor. A planar permanent magnet (15) whose direction of polarization is diametral to the axis (11) is positioned on the rotor. When the Hall-effect element (20) is positioned unsymmetrically, i.e. if the Hall-effect element (20) carries out an elliptic rotation in relation to the permanent magnet (15) the curve of the output signal comprises a steeply inclined zone and a flat zone. The above measurement device (10) requires no magnetically conductive parts, is very small and is relatively easy to mount in systems and devices.

摘要： The invention relates to a device for repositioning a rotating element in a defined base position. Said device comprises a spatially fixed cam (13) and a driving cam (14) which is coupled to the rotating element and can be moved in front of the fixed cam (13), each cam comprising a stop face (131, 132, 142) on opposite sides. The inventive device also comprises a clip spring (18) which clips the cams (13, 14) in a prestressed manner with two bent spring legs (181, 182). In order to ensure that there is no rotational play between the clip spring (18) and the cams (13, 14) in the base position, in at least one section of the spring leg (181) extending over the stop faces (141) of the cam, an elastic spring element (19) is provided, said spring element supporting the associated stop face (141) with a spring force which is smaller than the prestress force of the clip spring (18).
