- Figures 8 to 10 various views of a fifth embodiment of the invention.
- Figure 2 shows an instrumented bearing assembly for axle and rocket cap. More specifically, on the axle flare 1 is mounted a bearing comprising at least one inner ring 2, rolling bodies 3 and at least one outer ring 4. The elements of the bearing are shown schematically here. In order to isolate and delimit the so-called inner space of the bearing, several deflectors 51, 52 may be provided. According to this example, a first deflector 51 is connected to the fixed outer ring 4 while a second deflector 52 is connected to the rotating parts.
- a rocket cap 6 is provided, disposed on the end of the axle of the rocket 1.
- the rocket cap 6 is axially supported on the inner ring 2, the second deflector 52 being axially interposed between these two elements (6 and 2).
- the fixing of the rocket cap 6 on the rocket 1 is carried out by at least one screw 7, for example hexagonal head 8.
- the rocket cap 6 comprises a skirt 61 mounted around the rocket 1, and a bottom 62 which cap the end of the rocket 1.
- the rocket cap 6 is rotatably connected to the axle rocket 1 and the inner ring of the bearing 2 with one or more screws 7.
- lock washer 9 is provided in particular and in known manner to lock in rotation or the connecting screw 7.
- the lock washer 9 comprises, as shown in Figure 3, a disc of end 10 forming a bottom provided with orifices 101 for the passage of one or more connecting screws 7 and a central cutout 102 providing tabs 103 foldable on the screw head 8. This provision in itself is known, very close to the embodiment shown in Figure 1.
- the lock washer 9 further comprises a skirt 11 to be mounted at the end of the rocket cap 6 and more specifically to cover all or part of its outer cylindrical wall.
- the distal portion 110 of the skirt 11 is intended to be fitted on a portion of the outer wall of the rocket cap, as shown in Figure 2.
- the skirt 11 advantageously covers axially an annular magnetic sensor or encoder 12, axially disposed near the distal end of the rocket cap 6.
- the lock washer 9 or at least the skirt 1 1 is here made of a non-magnetic material for example based on copper, aluminum, or some types of stainless steels.
- This arrangement advantageously protects the magnetic encoder 12 in a simple manner.
- the magnetic field associated with the encoder 12 can pass through the skirt 11 and be transmitted to a sensor 13 radially disposed opposite the encoder 12.
- the lock washer 9 or more precisely the skirt 11 of the lock washer 9 can therefore provide here a dual function: the protection of the encoder 12 by the skirt 11 which axially covers the encoder; and the passage of the magnetic field of the encoder 12 towards the sensor 13 which will be located opposite.
- the encoder 12 is here protected before use, that is to say during the storage of the lock washer 9, but also during the mounting of the lock washer 9 on the rocket cap 6, and naturally during its use.
- the encoder 12 is perfectly maintained because the lock washer 9 has locking tabs 103 foldable on the head or heads of the assembly screws 7.
- the lock washer 9 and the encoder 12 are thus perfectly locked in rotation vis-à-vis the rocket cap 6 and the rocket itself 1. This rotational locking function is added to the other functions (already stated) performed by the lock washer according to the invention.
- the skirt 11 of the lock washer 9 has a proximal cylindrical bearing surface 1 12 of smaller diameter than the distal portion 110 and connected thereto. by a shoulder 111.
- the encoder 12 may be fixed on an annular support 200 fitted on the outer wall of the rocket cap 6, near its distal end.
- the encoder 12 is axially covered by the skirt 11, as in the first embodiment. All other characteristics are similar, and the only difference between the two embodiments lies in the connection of the encoder 12 which is here fixed on a portion of the outer wall of the skirt 61 of the rocket cap 6 via the support 200. This solution of course has all the advantages described above in connection with the first embodiment of the invention.
- the encoder 12 can be fixed on an entire cup 300 located in the volume delimited by the lock washer 9 and the rocket cap 6.
- the cup itself comprises a skirt cylindrical 301 which carries the encoder 12 and a bottom 302 pinched axially between the bottom 10 of the lock washer and the rocket cap 6.
- the bottom of the cup 300 is preferably traversed by the fastening screw or screws 7 which provide the mechanical support of the cup 300 and the encoder 12 with a very high reliability in time, even in case of significant vibrations.
- the skirt 11 and the bottom 10 of the lock washer 9 are in one piece, made in one piece in a non-magnetic material. According to the embodiment of FIG. 7, however, it is possible to provide a skirt 11 which is attached to the bottom 10 of the lock washer 9.
- the lock washer can then be provided with an indexing relief 11A of the angular position of the skirt cooperating with a housing of the bottom 10.
- the skirt is also provided with an indexing relief 1 1 B cooperating with a housing 300A of the encoder washer 300 ensuring its angular positioning relative to the skirt 11.
- the two-part construction offers the advantage of optimizing the choice bottom materials and skirt to adapt to their respective functions.
- the bottom 10 of the washer is not necessarily of non-magnetic material.
- the skirt equipped or not with the encoder, is preassembled on the bottom, before mounting the washer on the rocket cap.
- the skirt can be preassembled on the rocket cap, and the lock washer mounted in a second time.
- FIG. 8 to 10 are shown different views of another embodiment of an axle box according to the invention. Reference is made to the description of the preceding embodiments for the common elements, which bear identical reference numbers.
- This embodiment differs from the previous ones by the presence of a specific washer 9, shown in FIG. 9, and by the presence of a current collector 92 for producing a current feedback loop.
- the lock washer 9, which constitutes a support armature of the encoder 12 is constituted by a cylindrical skirt 1 1 integral with a bottom 10 having one or more lugs 113, provided with through holes 101 for fixing screws 7, the bottom 10 also having at least one opening 114, and in the illustrated embodiment, a number of openings 114 equal to the number of tabs 113, separating them.
- the encoder 12 is overmolded on the face of the skirt 10 turned radially outwardly.
- the assembly formed by the lock washer 9 and the encoder 2 is fitted on a cylindrical bearing surface 610 of the rocket cap, located between the axial end of the bottom of the rocket cap 6 and an intermediate shoulder 611.
- the cylindrical bearing surface 610 is preferably formed in the thickness of the bottom of the rocket cap, so as not to mechanically weaken the skirt 61 and not to disturb if necessary the passage of an electric current between the rotating crew and the casing 400 of the axle box in which is integrated assembly.
- An annular protective cover 80 consisting of a thin sheet of non-magnetic material is crimped on the rocket cap 6, so as to define with the rocket cap 6 and the lock washer 9 an annular space closed for the encoder ring 12.
- the positioning and fixing of the support of the encoder 12 are provided by the fastening screws 7, which may if necessary also simultaneously ensure the attachment of the rocket cap 6 to the axle stub 1. This fixation guarantees a good mechanical resistance over time, even in a severe environment subject to strong vibrations.
- the lock washer 9 is provided with tabs 103 intended to be folded over the heads of the fixing screws to lock the screw heads 8.
- a current return plate 90 is fixed to the rocket cap 6 by means of a specific screw 91.
- This screw 91 is located at one of the openings 114 of the lock washer 9, so that the current return plate 90 is in direct contact with the rocket cap 6.
- the screw 91 does not penetrate directly into the axle stub 1 and does not constitute a screw of fixing the rocket cap 6 to the axle stub axle 1.
- the washer 9 is a lock washer, that is to say a washer provided with tabs 103 for stopping the screw heads 8
