Definitions
- Rolling bearing in particular for non-driving wheels of a motor vehicle
- the present invention relates to rolling bearings, in particular ball bearings, or other rolling bodies, for non-driving wheels of motor vehicles.
- rolling bearings comprising two rows of balls, or other rolling bodies such as for example tapered rollers.
- w ball provided that, unless otherwise indicated. This must be understood as any use rolling element bearings in two rows of rolling elements.
- the inner rings of the bearings are mounted on a shaft or a wheel spindle, fixed in rotation, and the outer raceways are produced directly in the wheel hub, which then constitutes the outer ring of the bearing.
- Each inner ring then carries an inner raceway for one of the two rows of balls. The assembly and the maintenance are obtained by axial tightening of the two inner rings one against the other, commonly by means of an é. nut screwed on said tree or said rocket.
- Document FR-A-2717266 shows such an assembly, in which a fixed shaft is mounted in a bore of a fixed support and carries the two rings inside of the bearing.
- the outer ring in which the outer raceways are made, constitutes a hub of a wheel and carries a flange provided with a plurality of holes suitable for receiving bolts for fixing a brake disc and a rim .
- a nut screwed onto the end of the shaft bears directly on one of the inner rings and presses it against the other inner ring, which itself is in axial abutment against one face of the fixed support.
- the shaft being ' held axially on the fixed support by a shoulder located at its end opposite to that which carries the nut, the tightening of the nut therefore ensures the pressurization of the two inner rings of the bearing one against the 'other.
- the bearing running clearance, and the contact angle of the rolling bodies therefore dependent on the clamping nut, which is performed at the time of assembly of the hub onto the axle shaft.
- the performance of the bearing is therefore dependent on the mounting conditions on the vehicle manufacturer's production line, and is therefore liable to vary from one level to another in an uncontrolled manner. A loosening of the nut during operation is also possible and thus influencing the performance, or even very rapid deterioration thereof.
- the document EP 0343058 describes a similar bearing assembly, with the difference that the assembly of the shaft is reversed, that is to say that it is a shoulder at the axial end of the shaft which is in direct axial support against the inner race of the bearing, and the nut. is clamped, at the other end of the shaft, against one face of the fixed support crossed by the said tree. In this case too, the intensity of the tightening of the nut can influence the stresses undergone by the bearing and therefore its performance.
- one of the inner raceways is formed directly on the hub, which also carries an attached ring carrying the second inner raceway.
- the assembly is carried out by a collar, formed by plastic deformation on the hub after assembly of the rings and rows of balls of the bearing.
- This flange after it is formed by pushing back the metal from the hub, has a retention face, applied under pressure to an external face of the inner ring, so as to immobilize said ring axially, axial thrust against a shoulder a bearing surface of the hub constituting the second inner raceway for the second row of balls.
- a bearing assembly of this type is therefore produced as soon as it is manufactured with the axial play, or the preload, necessary for its subsequent application.
- One of the objectives of the present invention is therefore to provide a bearing whose performance is guaranteed as soon as it leaves its production line, and no longer during its assembly on the line of the vehicle manufacturer.
- Another objective is to limit the stresses on the collar in order to guarantee operation. good maintenance of the various components of the assembly.
- Yet another objective is to limit the efforts supported by this flange during use, in order to be able to reduce the dimensions, and consequently reduce the quantity of material and its weight, and also reduce the efforts to be exerted to push back the flange continued the decrease in the volume of material to be pumped.
- the invention relates to a rolling bearing with two rows of rolling bodies, in particular for a non-driving wheel of a motor vehicle, the bearing comprising a rotating hub constituting the outer rolling ring, gt a rocket element fixed on which are fitted the inner bearing rings in contact with each other, the rocket element being linked to a fixed support provided with rigid fixing means on the vehicle, characterized in that the rocket element has at one end directed towards the outside a shoulder against which a first inner bearing ring is in axial abutment, the fixed support being fitted tight on the rocket element, in abutment against a second inner bearing ring, and held axially by a flange formed by plastic deformation of an inner end of the rocket element, opposite the outer end.
- the flange is obtained by plastic deformation by centrifugal radial discharge of an annular end portion of the rocket element, after the two inner bearing rings have been successively placed on said rocket element and then the fixed support.
- the collar then has a retention face applied under pressure to an external front face of the said support, so as to axially immobilize said internal rings in abutment against one another and axially clamped together between, on the one hand, the shoulder of the outer end of the rocket element and, on the other hand , an internal front support face of the fixed support.
- the assembly of the various elements of the bearing is carried out on the production line, and it is final as soon as the flange is produced, the operating characteristics of the celebrating bearing frozen at this time, and therefore not liable to be modified during assembly of the bearing on the vehicle.
- mounting on the vehicle is achieved by rigid fixing means, such as conventionally screws, directly connecting the fixed support of the bearing on the vehicle, without the tightening of these screws having any influence on the assembly of the elements. to overcome.
- the rocket element has an external cylindrical surface serving as a bearing for the internal bearing rings as well as a fitting surface in the fixed support. These ranges preferably have the same diameter so that the cylindrical surface of the rocket is continuous over the entire length, which simplifies the production thereof.
- the inner bearing rings are preferably mounted on the spindle with a slightly tight adjustment, for example of the order of 10 to 30 ⁇ m, to avoid or at least reduce the risk of a possible rotation under load of the rings relative to the rocket.
- the rocket is preferably mounted in the fixed support with a larger tight adjustment, for example of the order of 40 to 70 ⁇ m, to ensure a rigid connection between rocket and support, not susceptible to separation even during large variations in charge.
- the rocket element has a generally tubular shape, thus making it possible to considerably reduce the weight of this part compared to a solid shaft.
- the rocket however has in its recess a reinforcing disc in a plane orthogonal to the axis, limiting possible deformations of the rocket.
- This disc is preferably located at the fitting of the rocket in the fixed support. In this way, it contributes to strengthening the rigidity of this fitting and therefore in particular to the resumption of the bending moment of the rocket.
- the forces directly experienced by the flange are less than if it was carried out on the side of the bearing rings.
- the flange can therefore be relatively lightened, therefore using less material and therefore being easier to deform plastically during its production.
- the invention considerably simplifies assembly and reduces its cost, by using a piece of very simple geometry, of continuous cylindrical outer surface as a rocket, with the sole exception of the end shoulder, on which are fitted the bearing rings and the fixed support which itself comprises as the only functional surfaces a simple bore of constant diameter and its two front bearing surfaces, in addition of course to the surfaces of connection to the vehicle.
- the assembly described in the aforementioned document also involves the production of a rolling track for a row of balls and a bearing surface and a specific front bearing face for the inner ring of the second row ball, directly on the support piece, which is more complicated and expensive.
- a seal is placed between the inner bearing ring located in contact with the fixed support, and the edge of the hub located on the side of said support, that is to say on the internal side of the vehicle;
- a plug is fitted into the bore of the hub on the external side, so as to ensure a perfect seal of the bearing against aggressions from the outside.
- FIG. 1 is a perspective view of a bearing according to the invention, for a non-driving wheel of a passenger motor vehicle;
- FIG. 1 is an axial sectional view of the bearing of Figure 1.
- the bearing illustrated in the drawings of FIGS. 1 and 2 comprises a hub 1 rotating relative to a fixed support 2.
- the hub 1 comprises a flange 11 designed so as to receive a brake disc and the rim of the wheel, not shown, which can be fixed to the said flange by screws or bolts passing through the fixing holes 12 circumferentially distributed.
- the hub 1 has a bore in which two raceways 13 are made for two respective rows of rolling bodies such as balls 4, positioned in a cage 41 ensuring equidistance between said balls, in a manner known per se, to constitute a two-row angular contact ball bearing.
- Each row of balls also rolls on an inner raceway produced on a respective inner ring.
- the geometry of the balls, hub raceways and inner rings, is such that the two inner rings 42, 43 are in axial abutment against each other when they are assembled with the two rows of balls located in their paths respective bearings.
- the two inner rings 42, 43 are fitted with a slightly tight fit, for example from 10 to 30 ⁇ m, on a spindle 3 comprising a recess 31, and in axial abutment against a shoulder
- the fixed support 2 also comprises a flange 21 comprising a plurality of fixing holes 22 distributed to ensure its fixing by screws or bolts to a suspension element of the vehicle for example.
- the rocket 3 passes through a bore 23 of the support, with a tight fit, for example from 40 to 70 ⁇ m.
- the support 2 is clamped in axial abutment against the inner ring 43 of the bearing by a flange
- the flange 33 produced by plastic deformation of the end of the rocket opposite to that carrying the shoulder.
- the flange 33 is produced by cold discharge of the material from an annular end 34 of the rocket against the front face 23 of the support located on the internal side of the vehicle.
- the spindle comprises a disc 36 'extending in a plane substantially orthogonal to the level of the flange 21.
- the thickness of the disc 36 being variable from one type of mounting to another to be adapted to the forces exerted on the bearing.
- a seal for example a lip seal 61 'of known type is inserted in a groove 14 machined on the edge of the hub bore, and covers the portion of larger diameter of the inner ring 43.
- a plug 62 for example made of plastic, and in the form of a cup, is inserted into the bore, the edge 63 of the cup abuts against the external front face 15 of the hub
- the invention is not limited to the embodiment illustrated in the example described above.
- the balls may be replaced by other rolling bodies, such as for example conical rollers.
- the forms and relative provisions of the flanges may also be modified, to adapt them to the parts which must be fixed thereto or on which they must be fixed, and to the fixing means used.
