Problems solved by technology

In conventional rotational speed sensors, for example, it is not possible to adjust the sensor element relative to the pole wheel
Especially when newer sensor elements (e.g. magnetoresistive) should be used, the orientation is important, so that the mentioned limitations are often not acceptable

Embodiment Construction

[0033] figure 1 A vehicle speed sensor is shown, which can be used in particular for commercial vehicles. According to one embodiment, the vehicle rotational speed sensor comprises a sensor element 110, a cylindrical sensor housing 120, in which the sensor element 120 is arranged, and an electrical connection cable 130, which is connected from the sensor housing 120 boots out. Furthermore, the vehicle speed sensor includes a bending limiting element 140 which is designed to limit the radius of curvature R of the connecting cable 130 directly in the region of its exit from the cylindrical sensor housing 120 .

[0034] The sensor housing 120 can be formed in one piece or in multiple pieces, for example. Thus, the sensor housing 120 can comprise, for example, an outer metal sleeve (for example made of a non-magnetizable material) and an injection molding compound formed therein, into which the sensor element 110 can be at least partially embedded. or the injection molded encap...

Abstract

The invention relates to a rotational speed sensor for a vehicle, comprising a sensor element (110), a cylindrical sensor housing (120) in which the sensor element (120) is arranged, an electrical connection cable (130) which leads out of the sensor housing (120), and a bending limiting element (140), the bending limiting element is designed to limit a radius of curvature (R) of the connection cable (130) directly in an extraction region of the connection cable (130) extracted from the cylindrical sensor housing (120).

Description

technical field [0001] The invention relates to a vehicle speed sensor, in particular for a commercial vehicle, a method for producing a vehicle speed sensor and in particular to a short axial speed sensor with a guided cable output. Background technique [0002] Conventional speed sensors are usually used in two sensor variants: (i) with an axial head shape, as an I-shaped or rod-shaped sensor, or (ii) with a radial head shape, in a radial In the case of the head shape, the cable output is bent by 90° relative to the sensor head, resulting in an L-shaped sensor. The structural shape used results from the installation situation or the desired course of the cable guide. [0003] The disadvantages of these conventional rotational speed sensors arise from the carefully guided cables on the axis along or away from the sensor. This requirement arises from a particular application to ensure correct operation. In conventional rotational speed sensors, for example, it is not poss...
