Abstract: This invention relates to a steering angle sensor, particularly for yawing moment control in automotive vehicles. In order to determine the required steering angle of the steered wheels the angle of rotation of the steering wheel is measured. To this end, a code disk is used which enables the reading of the position of the angle of rotation of the disk. As the steering wheel can perform a plurality of revolutions in order to pivot the steered wheels the result readable at the code disk is ambiguous. This invention suggests a counter which records the revolutions of the code disk, starting from a zero position. Further advantageous developments involve the design of the gear mechanism and the evaluation of the signals of the counter.

Abstract: The invention relates to a device for simultaneous peripheral electro-inductive hardening of bearing surfaces (2A, 3A) and transition A radii in crankshafts (1), comprising lifting pins (2, 3) arranged directly adjacent to each other and one behind the other with different angular positions on the plane perpendicular to the their axis of rotation (D), wherein inductors (8, 9) are provided which are placed on the lifting pins (2, 3) approximately in the same direction (C) thereof. A lifting pin (2, 3) is allocated to each inductor, which is arranged in such a way that it intersects the axial direction of the crankshaft (1). Said inductor comprises at least two inductor detents (8C, 8D, 9C, 9D) arranged parallel to each other. One inductor detent (8D, 9D) is arranged in an overlay area (4) of the lifting pins (2, 3) while the other inductor detent (8C, 9C) is arranged in an edge area of the lifting pin (2, 3) facing a cheek (5, 6).

Abstract: The invention relates to a steering angle sensor for motor vehicles. The object of the invention is to be able to provide the absolute value of the steering angle position of the steering wheel within a relatively short angle of rotation of the steering wheel. To this end, the invention proposes featuring two preferably concentric circular tracks (1, 2), wherein the first track (1) is used to determine the relative angular movement of the steering wheel and the second track (2) is used to provide the absolute value of the angle position. Advantageous further developments relate to two different coding options.
