Embodiment Construction

[0057] Figure 1a A schematic cross-sectional view of servo system 800 is shown. Servo system 800 is designed here by way of example with throttle valve 820 in throttle valve housing 810 . The throttle valve 820 is fixed on the shaft 830 of the throttle valve 820 by two fixing pieces 832 , such as two screws. The throttle is rotatable about a throttle rotation axis 834 that runs concentrically with respect to shaft 830 .

[0058] Rotation of throttle valve 820 about shaft 830 or about throttle rotation axis 834 may be driven by servo motor 840 . A servomotor 840 , for example a brushless DC motor, has a servomotor shaft 842 and a servomotor gear 844 fastened on the motor shaft, the servomotor gear 844 being rotatable about a servomotor axis 848 in two directions.

[0059] The servo motor gear 844 meshes with the first ring gear 852 of the two-stage gear 850 . On the two-stage gear 850 , the second ring gear 856 is fixedly connected with the first ring gear 852 along the two...

Abstract

The invention relates to a measuring device used for measuring the rotation angle (alpha) in a non-contact manner. The measuring device includes a first member (200) fixedly connected with influencing elements (500, 280, 580). The measuring device also includes a second member (500) having sensing elements (510, 310, 610). Here the first member (200) and the second member (300) can rotate relative to each other. Here the sensing elements (510, 310, 610) are implemented to be used for measuring the rotation angle value of the first member (200) about the second member (500) according to the electric field and / or magnetic field of the influencing elements (500, 280, 580) particularly in a non-contact manner. To realize rapid fixing of the influencing elements (500, 280, 580) on the first member (200) with safe manufacture and low price, the influencing elements (500, 280, 580) are adhered to the first member (200) by means of double-sided adhesive adhesives (260, 262, 264).

Description

technical field [0001] The invention relates to a measuring device for contactless determination of an angle of rotation (α). Background technique [0002] Magnetic field-based sensors or measuring devices for the contactless determination of the angle of rotation require a sensor element or magnetosensitive element which operates, for example, with the Hall effect, planar Hall effect or magneto-resistive effect (MR) Or the giant magnetoresistance effect (GMR) as the basis. In addition to the magnetically sensitive element, a magnet is required in a measuring device of this type in order to perform the detection (rotationally or in translation). For this purpose, for example, permanent magnets are attached to the first component as magnet holder. [0003] In other sensors, the angle of rotation can be determined contactlessly by an inductively operating sensor or an inductively operating measuring device. For this purpose, for example, structural elements are provided whi...
