State of the art

Background of the invention

In a variety of rolling bearing applications, it is necessary to arrange a sensor in the correct position to a signal generator and then attach. In particular, rotational speed sensors, which interact with a signal transmitter which is mounted on a rotatable part of the rolling bearing, can function optimally only at a certain detection distance between sensor and signal generator.

For example, in wheel bearings in the automotive sector so-called speed sensors for anti-lock braking systems are used, in which a subsequent deviation from the optimum detection distance can lead to signal loss, which limits the operation of the anti-lock braking system or even prevented. The speed sensors are usually based on magnetic effects, such. As the Hall effect, the magnetorestrictive effect or induction. However, a similar problem also arises in rolling bearings of the aviation industry, such as bearings for jet engines, or even rolling bearings for rolling mills and paper machines.

On the one hand, the fixture must be secure enough to prevent any subsequent change in position or incorrect attachment during installation of the sensor, on the other hand, the fixture should be cost effective to keep the installation process, have few separate components, and be simple in design.

Summary of the invention

The object of the invention is to provide a sensor, or a sensor arrangement, wherein the sensor can be fastened cost-effectively, simply and securely in a stationary rolling bearing part, a journal or a carrier.

The object is achieved by a wheel bearing unit of the type mentioned above in that the guide surface forms means for mounting the sensor.

According to the invention, the sensor is provided with a housing and a signal sensor arranged in the housing. A signal receiver is understood to mean a measuring element which can detect a variable magnetic field. For this purpose, the signal sensor may for example have a coil in which an induction current is generated. Optionally, the coil is provided with flux-conducting elements, such as an iron core, which amplify or advantageously conduct the magnetic flux. If the sensing is based solely on the induction current, then it is a passive sensor. Alternatively, it is conceivable to actively energize the sensor and to detect changes in the magnetic field based on the magnetic flux-changing properties of the signal generators as a function of their position. Thus it would be an active sensor.

The housing of the sensor has at least one guide surface for guiding the sensor when it is positioned in a fixed roller bearing part or a carrier. A guide surface delimiting the sensor outwards becomes, for example, by sliding the adjacent guide surface or by another Guiding function of the guide surface, moved to the intended position within the rolling bearing assembly or within a rolling bearing receiving carrier or otherwise conveyed. The carrier is, for example, a wheel carrier, which is provided for receiving a wheel bearing. Alternatively, the carrier may be a journal or a part of a journal. The interaction between the guide surface and an inner surface of the rolling bearing assembly, the fixed roller bearing part or the carrier, the sensor is moved in a linear direction to the intended positions.

In addition to the positioning properties of the guide surface, the guide surface forms means for attaching the sensor. By way of example, these fastening means can bring about a frictional connection between the guide surface and the inner surface of the rolling bearing arrangement or of the carrier, so that the sensor can not be moved in the direction of movement, as well as during installation or in opposite directions. Perpendicular to the direction of movement is during installation before a positive connection due to said inner surface and the guide surface.

Alternatively or optionally, the means for fastening the guide surface lead to a form fit, which prevents the unwanted movement of the sensor in the direction of movement of the installation, or opposite. By way of example, the means for fastening the guide surface are form-variable, in particular elastic, fastening means.

In an advantageous embodiment, the guide surface is partially formed by a support ring or reinforced by the support ring. This makes it possible to fasten the housing of the sensor at its intended position non-positively and / or positively. For this purpose, the housing must be able to absorb a static force perpendicular to the installation direction of the sensor, as it is applied by a locking screw.

The support ring consists for example of a metal, in particular sheet metal, or else of a stable plastic, wherein a certain elasticity of the sensor housing is achieved via the ring shape. A locking screw can be brought into direct contact with the support ring, which either has a recess on its outer surface for the end of the screw, or the locking screw provided for a frictional end of the screw. They come to the plant surface at the end of the screw can this be a large area and possibly designed with a high frictional resistance, which is caused for example by a roughening or a regular structure or at least supported.

Alternatively, the support ring may support the housing of the sensor by being disposed within the housing, or under its inner surface, so that the screw force can be passed from the housing to the support ring. Thus, it is possible that a uniform housing can be selected, which does not have to be selected under stability criteria, but may be designed to be very thin, for example, with a comparatively cheap material. This is also useful if the sensor must be protected against splash water and foreign particles. In a unitary or even one-piece housing, as can be produced for example by a plastic injection molding process, an excellent sealing effect is achieved, whereby due to the support ring on a required stability for sensor attachment must not be waived.

In an advantageous embodiment, the guide surface on a plastically deformable in the screw action outer layer. This makes it possible to achieve a positive connection with the locking screw, which secures the position of the sensor. This is done in combination with the traction that makes the locking screw on the outer layer anyway. However, it must be ensured by the support ring that the screw can not deform the housing so plastically that a hole is formed, or the positive locking is lost.

In an advantageous embodiment, the guide surface is formed by a hollow cylindrical sleeve of the housing and the sleeve is provided at an open sleeve end for concentrically receiving a screw.

The screw is also a locking screw, which is conically formed on its threaded part, which when expanding the locking screw in the open end of the sleeve, the sleeve end is widened. This can for example be done with a deformable sleeve material. The outer circumference of the sleeve is increased, whereby the adhesion to the inner surface of the rolling bearing assembly or the carrier is increased. The locking screw has larger radii at its threaded portion near the screw head than at the other end of the screw, which is first inserted into the open end of the sleeve. Advantageously, the sensor can be inserted up to a stop, whereby this already occupies the optimum detection distance, and is then fixed non-positively with the conical locking screw.

Advantageously, by screwing the conical locking screw in the sleeve of Outer circumference of the sleeve by means of expansion gaps enlarged. This makes it possible to use a sleeve material which does not necessarily have to be highly deformable. It is conceivable that, for example, a metal sleeve is used, wherein the expansion gaps form sleeve webs which are diametrically removable from one another in that the conical locking screw is screwed into the sleeve. Although the outer circumference of the sleeve is interrupted by the expansion gaps, but can be greater, the more expansion gaps are provided. Ideally, the expansion gaps are circumferentially equally spaced from each other.

In an advantageous embodiment, the guide surface partially or completely on a roughening. This roughening consists of a similar hatched on the guide surface material, which is intended to increase the adhesion between the inner surface and the guide surface. It is particularly advantageous if the inner surface consists of a deformable material, so that the excess produced can be compensated by deformations of the thrown up material.

In an advantageous embodiment, the guide surface on elastically deformable retaining elements. The elastically deformable retaining elements have the property of being elastically deformable when stressed in one direction, and to form a positive fit when stressed in the opposite direction. Thus they do not stand in the way of a positioning, but can contribute at least in one direction to the attachment.

Advantageously, the sensor has oppositely directed retaining elements at opposite ends of the housing. The inserted end of the sensor in this case has retaining elements which are elastically stressed during the deflection and prevent movement opposite to the installation direction. By mounting a mounting ring on the other end of the sensor, the mounting ring can be used for locking, since the retaining elements at the other end of the sensor bring about a positive connection with the mounting ring and allow movement of the mounting ring only in the direction of support or stationary rolling bearing. This results in enormous advantages in the installation of the sensor, because no screws must be tightened and the sensor, quasi held in the mounting ring, with a single, possibly automated, movement can be positioned and fixed.

In an advantageous embodiment, the sensor is a speed sensor, a structure-borne sound sensor, a temperature sensor or a torsion sensor. Basically, any sensor can be used in the context of the invention, which must be precisely positioned for its optimal function. Furthermore, the sensor may be both a passive or active sensor. In particular, when using an active sensor further additional functions can be optionally offered when a precise position can be maintained by the attachment of the sensor. For example, in the case of immutable positions of the sensor in the event of a signal drop, damage to the rolling bearing can be inferred (so-called end-of-life sensor). Thus, a speed sensor could take over the function of such an end-of-life sensor.

Advantageously, the rolling bearing is designed as a radial bearing, angular contact bearings, ball roller bearings, tapered roller bearings, wheel bearings or as a combination of said rolling bearings and can be connected to one of its rotatable parts, for. B. on an inner ring or a hub, a signal generator, for example in the form of an encoder ring with alternating magnetic north and south poles wear.

A substantially cylindrical sensor 11 can end with the signal transducer 3 moving forward in the fixed axle journal 1 moved in or be threaded.

An unillustrated stop, for example, integral with the journal 1 is executed, or belongs to another fixed component of the rolling bearing assembly or a carrier, produces a positive connection in the direction of adjustment. When pushing against the stop is the sensor 11 optimally positioned such that the intended detection distance from the signal receiver 3 to the signal generator, which is not shown, is taken.

For fixing the locking screw 2 attracted and loaded perpendicular to the installation direction, the housing of the sensor 11 , which at this point through the support ring 12 is formed. The support ring 12 is a metal ring, which advantageously the supply line 4 for the signal receiver 3 includes while the housing provides stability, as well as easy access for the supply line 4 creates.

The adjustment cap 14 serves to establish the optimal distance to the stop not shown. The thickness of the adjustment cap 14 can be advantageously varied, bringing the sensitivity of the signal pickup 3 , or the signal strength of the signal generator not shown, can be taken into account. With the adjustment cap 14 the detection distance is advantageously adjustable as a function of the variables mentioned. It is further advantageous that a variety of products provided for different applications sensors on the formation of multiple adjustment caps 14 can be reduced, which is always placed on the same basic sensor, z. B. snapped, can be.

The supply line 4 can be designed multi-core, which provides a power supply for the signal sensor 3 , as well as one or more signal or data lines may be included. The supply line 4 leads into a cable connection 13 which merges into a cable which the supply line 4 outside the sensor 11 protects.

2 shows a sensor arrangement with a sensor 21 with a plastically deformable outer layer 24 , The outer layer 24 is a fastener of the guide surface 26 of the sensor 21 that the signal receiver 3 Axially covering in the detection direction and radially. This results in very good properties of the sensor 21 in terms of tightness over splash water and dirt particles, but also during handling and during installation is the sensor 21 very insensitive.

The support ring 22 has, as well as the support ring 12 out 1 , the function of Feststellkraftaufnahme. When tightening the locking screw 2 placed in the fixed bearing part 1 the thread is screwed, the load is perpendicular to the longitudinal axis of the sensor 21 on the support ring 22 passed the housing of the sensor 21 reinforced, but on its cylindrical outer surface through the outer layer 24 is covered.

Advantageously, the support ring 22 concentric with the longitudinal axis of the sensor 21 arranged and allows the implementation of the supply line 4 as they already are from the embodiment of 1 is known and how they are in the cable connection from the sensor 21 led out, but at the same time protected from external influences.

At the detection end of the sensor 21 at which the signal sensor 3 inside the sensor 21 is arranged on the outer layer 24 a distance layer 25 Applied to the distance to an unillustrated auto switch when installing the sensor 21 should keep. When inserting the sensor 21 this abuts an encoder, wherein the detection direction can be aligned radially or axially to the rotational axis of the rolling bearing, and is positioned therewith. After fixing the screw 2 The sensor is in the journal 1 attached. When commissioning the sensor assembly of the encoder causes by a slight removal of material at the spacer layer 25 a free grinding of the own annular movement space.

Advantageously, the material is the spacer layer 25 a soft material, which is ideally non-magnetic and can not conduct magnetic flux. Further, it is advantageous if it is a material which becomes liquid at an operating temperature of the rolling bearing, runs on the wheel bearing and reaches the roadway.

Alternatively, the material sticks to the encoder or signal transmitter and remains there for the entire service life of the rolling bearing.

3 shows the sensor arrangement 2 with tightened locking screw 2 that the outer layer 24 plastically deformed with the end of the screw. This is the locking screw 2 in the outer layer 24 penetrated without piercing them. However, the sensor can 21 no longer be moved in a direction whose longitudinal axis. This is the sensor 21 positively and non-positively attached.

The supply line 4 extends substantially along the longitudinal axis of the sensor 21 from the signal receiver 3 to the cable connection 23 ,

Incidentally, on 2 directed.

4 shows a sensor assembly with a sleeve and a conical locking screw 42 in exploded view.

The signal receiver 3 of the sensor 41 is in a holder 49 held, the holder 49 in the sleeve 44 is plugged or otherwise with the sleeve 44 connected is. The guide surface 48 is from the cylindrical surface of the sleeve 44 formed, with the one open end of the sleeve 44 to hold the holder 49 and the other open end of the sleeve for receiving a conical locking screw 42 is provided.

The conical locking screw 42 has an external thread 47 on which on the conical part of the locking screw 42 is formed, wherein in the vicinity of the screw head is a larger outer diameter than at the screw end, which for insertion into the sleeve 44 is provided.

The hollow cylindrical inner surface of the sleeve 44 has an internal thread 45 which is for a screw-like recording of the conical locking screw 42 is provided. Advantageously, the sleeve forms 44 at this open end expansion column 46 out, which is a widening of the sleeve 44 when screwing in the screw 42 support. The expansion of the sleeve 44 can therefore completely or partially by the elastic property of the sleeve 44 yourself supported. The expansion column 46 however, are particularly suitable for non-elastic materials such. As metals or hard plastics. It is also not disadvantageous if the expansion gaps 46 the grooves of the internal thread 45 cut through, as an elastic stress on the sleeve 44 only in the radial direction to the longitudinal axis.

Advantageously, the conical locking screw 42 hollow inside, so that through the holes 43 the supply line 4 for the signal receiver 3 through the conical locking screw 42 can be passed and also when detecting, or when attaching the sensor 41 nothing is damaged. It makes sense the bore 43 on the screw head with a sealing element, so that no water or dirt particles in the sensor 41 can penetrate.

So first, the holder 49 in the sleeve 44 attached. Subsequently, the sleeve 44 into the hole 5 of fixed axle journal 1 is inserted and then the supply line 4 through the holes 43 the conical locking screw 42 guided, after which the locking screw 42 in the open end of the sleeve 44 is screwed, wherein the outer diameter and the outer circumference of the sleeve 44 be enlarged and a frictional connection with the bore 5 cause.

5 shows a sensor arrangement with a sensor 51 with a roughening conditional excess. The sensor 51 is designed substantially cylindrical and can with an evaluation of the cable application 53 at the cable end of the sensor 51 is attached to be connected. The opposite end of the sensor 51 is the detection-side end, which first into the hole 5 Part of the stationary rolling bearing 1 is introduced.

The sensor 51 has a lateral surface, the outer diameter exactly to fit with the bore 5 worked. Thereafter, the outer surface was roughened such that material of the outer surface radially beyond the original dimension of the outer diameter and now form an oversize.

This roughening can be caused for example by a rolling, a coarse-grained grinding process or by the application of a turning tool. This occurs on the lateral surface of the sensor 51 a cross-hatched pattern.

Advantageously, the roughening in the radial direction to the longitudinal axis of the sensor 51 a structural elasticity, bringing the sensor 51 by simply pressing into the hole 5 Can be permanently attached. So advantageous that no further aids are necessary to attach the sensor 51 to accomplish. Only a stop perpendicular to the press-in is advantageous for the positioning of the sensor 51 during its installation.

6 shows a sensor arrangement with a retaining elements 65 . 66 having sensor 61 ,

The sensor 61 has, as the preceding embodiments, a signal pickup 3 with supply line 4 and a cable connection 63 on. The guide surface 68 touches the inner surface of the hole 5 of fixed axle journal 1 only by means of the retaining elements 65 and 66 ,

The sensor 61 is very easy to install because except the bore 5 no further fasteners on the axle journal 1 and no further separate fasteners for the sensor 61 necessary.

The retaining element 66 at the cable end of the sensor 61 is conical, so that when pressing the sensor 61 into the hole 5 a restraining force is built up, which is a stop on the stationary journal 1 or replaced elsewhere. Because of the retaining element 66 is elastic, different positions can be achieved during Einpressvorgang with a defined press-in force. The retaining element 66 thus forms a frictional connection with the inner surface of the bore 5 ,

The retaining elements 65 gain their restraint function by engaging behind the journal in the radial direction. When inserting into the hole 5 become the retaining elements 65 due to a cone-like outer surface from the edge of the bore 5 elastically stressed radially inwards and lie against the sensor 61 at. Once the interaction with the inner surface of the bore 5 disappears, snap the retaining elements 65 in their original, unclaimed form and form a positive retention against the insertion of the sensor 61 ,

By a plurality of these substantially annular retaining elements 65 can be achieved in a number of different positions depending on the insertion force during the installation process. The retaining elements in this case need not be annular, but can also in the circumferential direction axially to the longitudinal direction of the sensor 61 be offset, bringing multiple axial positions of the sensor 61 can be achieved. It would be conceivable, for example, a spiral-like arrangement of the retaining elements on the guide surface 68 At the detection end of the sensor 61 ,

Furthermore, the sensor must also 61 not necessarily have a substantially cylindrical shape, wherein the axis of symmetry of the cylinder coincides with the direction of movement during installation, but may also have a cuboid shape or another shape. This applies to all embodiments, with the exception of the embodiment of 4 ,

7 shows a sensor arrangement with a differently oriented retaining elements 74 . 75 having sensor 71 ,

The retaining elements 74 are annular and are sawtooth-shaped in longitudinal section, so that, similar to the embodiment of the 6 , a retention caused by positive locking when the influence of the inner surface of the bore 5 not available. A majority of the retaining elements 74 also allows a large number of positioning options. It can always retain elements 78 which remain elastically stressed in the final sensor position.

Advantageously, at the cable end also retaining elements 75 formed on the guide surface, wherein this counter to the retaining elements 74 are oriented. The retaining elements 75 are not stressed elastically, wherein the claimed retaining elements 77 at the cable end with a mounting ring 76 interact.

The mounting ring 46 is used to the sensor 71 to position in the axial direction by the mounting ring 76 upon reaching the sensor position on the cable end over the retaining elements 75 is striped, then a movement in the opposite direction of the mounting ring 76 prevent so the mounting ring 76 when abutting the axle journal 1 yourself and the sensor 71 permanently attached to this.

It is advantageous on the mounting ring 76 to provide a predetermined breaking point, thus dismantling the sensor 71 can be performed.

Advantageously, the sensor 71 a distance layer 25 , as well as in the embodiment of 2 and 3 described, which is initially brought into direct contact with the signal generator. That way, the sensor has to be 71 when mounting the mounting ring 76 not be kept consuming.

Advantageously, the installation process of the sensor 71 very easy to automate by first the mounting ring 76 is wound on the cable end, wherein the flexibility of the retaining elements 75 is low enough to the sensor 71 along with the held mounting ring 76 to move, with only the mounting ring 76 the force to insert the sensor 71 into the hole 5 must be exercised. As soon as the sensor 71 comes on the signal generator, give the retaining elements 75 after and the mounting ring 76 shifts in relation to the already positioned sensor 71 until the mounting ring 76 on the fixed journal 1 comes to a stop. This can be done by means of the mounting ring 76 held sensor 71 from a robotic arm into the hole 5 be plugged in. Both the positioning and the attachment are implemented in one process.

Incidentally, the embodiment of the 6 directed.

In summary, the invention relates to a sensor, or a sensor arrangement, comprising a housing and a signal sensor arranged in the housing, wherein the housing has at least one guide surface for guiding the sensor in the sensor positioning in a fixed journal or other carrier. The teaching is directed to a simple and secure positioning of the sensor within a carrier or a stationary rolling bearing part, wherein the outer guide surface of the sensor forms means for mounting the sensor. Thus, the guide surface assumes a dual function, namely on the one hand the leadership and on the other hand, the attachment of the sensor. This simplifies the installation of the sensor significantly, because the sensor is only to be threaded to the intended stop and thus also attached at the same time or can be fixed with little effort after positioning.
