Abstract
The utility model relates to a speed sensor for preventing a car from locking. The casing of the sensor is installed on a bracket. An induction coil is arranged in the lower part of the casing, and a left soft magnet slice and a right soft magnet slice are respectively arranged in the induction coil, and permanence magnetism steel is clamped between the two soft magnet slices. A magnetism conducting signal fluted disc with a plurality of teeth on the outer circumference is arranged under the bracket. The utility model has the advantages of simple structure, easy installation, and measurement without depending on a rotation direction, and is especially suitable for device for preventing a car from locking.
Description
Technical field
The utility model relates to a kind of automobile anti-lock braking speed pickup, is particularly useful for the automobile anti-lock braking device.
Background technology
State Intellectual Property Office in a kind of magneto-electric automotive speed sensor utility model patent of bulletin on February 26th, 2003 is, be installed on the support, permanent-magnet steel is arranged in sensor outer housing, with permanent-magnet steel join be the coiling inductive coil soft magnet core, sensor outer housing one side is equipped with the shielded conductor that links to each other with inductive coil, below the support, be provided with the signal fluted disc of uniform several teeth of the anodontia remainder of excircle the preceding paragraph.Yet, the magneto-electric automotive speed sensor cost height that this patent relates to, and can not be used for the automobile anti-lock braking device.
Summary of the invention
In order to overcome above-mentioned weak point, the utility model provides a kind of project organization of optimization, and cost of products is reduced, and can be used for the speed pickup of automobile anti-lock braking device.
The technical solution adopted in the utility model is: the housing of sensor installation on support, an inductive coil is equipped with in inside, housing lower end, each a slice soft magnetism iron plate about being provided with in it, accompany a permanent-magnet steel between two soft magnetism iron plates, the support below is provided with the magnetic conduction signal of several teeth fluted disc on the excircle.
Advantage of the present utility model is: simple in structure, simple installation, measurement do not rely on rotation direction, are particularly useful for the automobile anti-lock braking device.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further.
As seen from the figure, the housing 3 of sensor installation on support 2, an inductive coil 5 is equipped with in inside, housing 3 lower end, each a slice soft magnetism iron plate 7 and 9 about being provided with in it, accompany a permanent-magnet steel 4 between two soft magnetism iron plates 7,9, support 2 belows are provided with the magnetic conduction signal of several teeth fluted disc 6 on the excircle.
Be the application example of the utility model in the automobile anti-lock braking device below, signal fluted disc 6 links together with axletree, the permanent-magnet steel 4 of sensor with about each a slice soft magnetism iron plate 7 and 9 constitute probe, the probe and relative installation of tooth of signal fluted disc 6, a clearance 8 is arranged therebetween, when running car, signal fluted disc 6 is with wheel, formed the air-gap field of alternation between the probe of sensor and the signal fluted disc 6, having produced the alternating voltage signal in inductive coil 5 is the vehicle wheel rotational speed high low signal, delivers in the electronic control unit of automobile through shielded conductor 1.
