Description

Title of the invention: Arrangement comprising a wheel hub and a support. Technical field of the invention

[0001] The invention relates to an arrangement comprising a wheel hub and a support. The invention also relates to a body comprising such an arrangement. The invention also relates to a vehicle comprising such a body or such an arrangement. State of the prior art

[0002] A vehicle, in particular a motor vehicle, generally comprises a support for each wheel hub. Such a support is generally movable relative to a body of such a vehicle. Generally such a wheel hub is called a spindle and such a support is called a steering knuckle. Such a steering knuckle generally comprises at least one attachment means for a means for stabilizing the wheel mounted in a pivot connection at the steering knuckle, in particular a means for stabilizing the wheel in the vertical direction or substantially in the vertical direction. Such a stabilizing means is for example a stabilizer bar or anti-roll bar. Furthermore, such a steering knuckle generally comprises at least one means for attaching a shock absorber extending between such a steering knuckle and a portion of such a vehicle body.Generally, at least one means for attaching a steering knuckle for a stabilizing means and / or for a shock absorber and / or for a steering element is arranged at the bottom of such a steering knuckle. In particular, such an attachment means creates a downward projection outside a cylindrical space extending within such a wheel.

[0003] Thus, such a projection may come into contact with an element of street furniture and / or a sidewalk and / or the ground in the event of a significant hole in the roadway, for example called a "pothole". Such contact or impact, in particular when reversing, may damage such a fixing means for a stabilization means and / or for a shock absorber and / or for a steering element. The consequences of such an impact are a lack of parallelism of the set of wheels concerned and / or the immediate or future breakage of the fixing means concerned.

[0004] Such a situation is not acceptable. Presentation of the invention

[0005] The object of the invention is to provide an arrangement which overcomes the above drawbacks. In particular, the invention proposes an arrangement providing reinforcement for a fixing means for a stabilizing means and / or for a shock absorber and / or for a steering element. Summary of the invention

[0006] To achieve this objective, the invention relates to an arrangement, in particular for a vehicle, comprising a wheel hub, in particular of the spindle type, and a support, the support comprising: - a means for receiving the wheel hub, in particular a bore having a main axis extending transversely or substantially transversely, - a first fixing means, in particular a bore, for a first means of holding relative to the ground, the first fixing means extending below the means of receiving the wheel hub, the first fixing means extending projecting downwards from the support, the support comprising a reinforcement extending upwardly from the first fixing means, or substantially from the first fixing means, in a vertical and longitudinal plane or substantially in a vertical and longitudinal plane.

[0007] The support may comprise a second fixing means for a second means of holding relative to the ground, in particular a second fixing means having an axis extending longitudinally or substantially longitudinally, the second fixing means being able to be arranged above the first fixing means in the vertical direction.

[0008] The reinforcement may extend between the first fastening means and the second fastening means.

[0009] The hub receiving means and the first fixing means and the second fixing means may be arranged to form substantially a triangular shape extending in a vertical and longitudinal or substantially vertical and longitudinal plane.

[0010] The support may comprise material within the triangular shape.

[0011] The support may comprise a cavity within the triangular shape, in particular a cavity in the general shape of a triangle.

[0012] The section of the reinforcement may be circular, square, rectangular, or T-shaped, the section possibly being constant between the first fixing means and the second fixing means.

[0013] The invention also relates to a body for a vehicle, in particular for a motor vehicle, comprising an arrangement as defined above.

[0014] The invention also relates to a vehicle, in particular a motor vehicle, comprising an arrangement as defined above or a body as defined above. Presentation of figures

[0021] The direction in which a vehicle, in particular a motor vehicle, moves in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called the transverse direction Y. The third direction, perpendicular to the other two, is called the vertical direction Z. Thus, a direct XYZ reference frame is used in which X is the longitudinal direction in the front-rear direction of the vehicle, therefore directed towards the rear, Y is the transverse direction directed towards the right and Z is the vertical direction directed upwards. The forward direction corresponds to the direction in which the vehicle usually moves in the longitudinal direction and is opposite to the rear direction.

[0022] As illustrated in [Fig.l], a vehicle 1, for example a motor vehicle, comprises a body 100. The vehicle 1 or the body 100 comprises, for example, four wheels 8. The vehicle 1 or the body 100 comprises at least one arrangement 2. For example, an arrangement 2 is provided at at least one rear wheel, or even each rear wheel of the vehicle, or at at least one front wheel, or even each front wheel, or even at all the wheels of the vehicle. For example, each front and / or rear wheel comprises a means 6 for stabilizing relative to the ground. Preferably, the stabilizing means is of the stabilizer bar or anti-roll bar type. For example, the rear wheels have a common stabilizing means and / or the front wheels have a common stabilizing means.

[0023] More specifically, as illustrated in Figures 2 and 3, the arrangement 2 comprises a wheel hub 3, for example commonly called a spindle. The arrangement 2 also comprises a support 10, for example commonly called a spindle carrier. Note that the support 10 supports the wheel hub 3 so that a portion of the wheel hub is pivotally connected relative to the support 10.

[0024] For this purpose in particular, the support 10 comprises a means 13 for receiving the wheel hub 3. Preferably, as illustrated in [Fig. 2] in particular, the means for receiving the hub 3 is a bore 13 having a main axis AP extending transversely or substantially transversely. Preferably, the hub comprises a rotation means such as a ball or roller or needle bearing, arranged at least partially within the bore 13 (not illustrated). Thus, the hub 3 comprises a first part 31 intended to be fixed on the support 10 and a second part 32 in rotation relative to the first part 31. The second part 32 is intended to receive a wheel 8 and, possibly, one or more braking elements, for example a brake disc 9 as illustrated in [Fig. 5]. For example, a deflector or cover 20 is arranged between the support 10 and the brake disc 9.For example, a fixing means 16 arranged at the top of the support 10 allows the fixing of a shock absorber 5 (see figures 2 and 3). For example, as illustrated in [Fig.3], orifices or holes 14, preferably comprising shoulders or counterbores, are provided around the bore 13. These holes 14 participate in the fixing of the first part 31 of the hub 3, preferably by using bolts passing through these holes 14 and holes provided in the first part 31 of the hub 3, on the stub axle carrier 10.

[0025] As illustrated in Figures 1, 2 and 3, the support 10 also comprises a first fixing means 11 for a first means of maintaining or stabilizing 6 relative to the ground. For example, the first fixing means 11 is a bore. Advantageously, such a bore 11 allows the reception of a damping element (not illustrated), notably known under the brand name SILENTBLOC (registered trademark). Such a damping element is for example interposed between the support and the first stabilizing means 6.

[0026] The first fixing means 11 extends below the receiving means 13 of the wheel hub 3. More precisely, the first fixing means 11 extends projecting downwards from the support 10. Furthermore, for example, the first fixing means 11 extends beyond a maximum radius RM of an internal cylindrical space E of axis AP extending within the wheel 8, as illustrated in FIGS. 2 and 3. For example, the first fixing means 11 extends in a radial direction relative to the axis AP near an internal sidewall 7' of the tire 7 equipping the wheel 8. Preferably, the first fixing means 11 extends in the transverse direction towards a median plane M of the vehicle, beyond the wheel 8, and / or beyond the tire 7 equipping the wheel 8, as illustrated in [Fig.2]. In other words, the first fixing means 11 protrudes from the wheel 8 in the transverse direction towards the median plane M.

[0027] As illustrated in [Fig. 3], the support 10 further comprises a reinforcement 15 extending upwards from the first fixing means 11, or substantially from the first fixing means 11, in a vertical and longitudinal plane or substantially in a vertical and longitudinal plane.

[0028] For example, the support 10 comprises a second fixing means 12 for a second means of holding or stabilizing relative to the ground (not shown). For example, the second fixing means 12 comprises a bore having an axis A12 extending longitudinally or substantially longitudinally. For example, the second fixing means 12 is arranged above the first fixing means 11 in the vertical direction, for example by being offset from each other in the longitudinal direction. Advantageously, the second fixing means 12 allows the reception of a damping element (not shown), in particular known under the brand SL LENTBLOC (registered trademark). Such a damping element is for example interposed between the support and the second stabilizing means if necessary.

[0029] Preferably, the reinforcement 15 extends between the first fixing means 11 and the second fixing means 12, for example being rectilinear or not, for example forming a substantially curve.

[0030] For example, the receiving means 13 of the hub 3 and the first fixing means 11 and the second fixing means 12 are arranged relative to each other so as to form substantially a triangular shape extending in a vertical and longitudinal plane or substantially vertical and longitudinal. Preferably, the support 10 extends generally in a vertical and longitudinal plane.

[0031] Preferably, as illustrated in [Fig.3], the support 10 comprises a cavity C at within the triangular shape comprising the reinforcement 15. For example, the cavity C has a triangular shaped area. The section of the reinforcement 15 is for example circular, and / or square, and / or rectangular. Alternatively, or in addition, or on a portion of the reinforcement 15, the section is T-shaped, as illustrated in section AA of [Fig.4]. Note that the section is constant or not between the first fixing means 11 and the second fixing means 12.

[0032] For example, the support does not comprise a cavity but material within the triangular shape (case not illustrated), for example a veil of material, that is to say a relatively small thickness of material compared to that of the reinforcement 15, or even of the rest of the support.

[0033] Preferably, the material used is cast iron, in particular spheroidal gray cast iron. In this case, preferably, the spindle carrier 10 is obtained by foundry, in particular by molding. For example, the receiving means 13 and / or the fixing holes 14 and their possible counterbores or shoulders and / or the second fixing means 12 and / or the first fixing means 11 are obtained by machining.

[0034] In summary, the solution relates to an anti-shock ramp 15 arranged on the stub axle 10. Thus, in the event of an impact, in particular when reversing, when moving backwards, the triangulation, that is to say the connection of the receiving means 13 of the hub with the first fixing means 11 and the second fixing means 12 creates the reinforcement 15. Preferably, the reinforcement is created by adding material between the first fixing means 11 and the second fixing means 12. Thus, when the stub axle carrier 10, in particular a rear stub axle carrier, comes into contact with a curb 4 (see Figures 1 to 3), it is the reinforcement 15 of the stub axle carrier 10 which rubs against, slides on, bears on the curb. As a result, the stub axle carrier 10 is offset vertically upwards, which helps the stub axle carrier (and consequently the hub 3 and the wheel 8 adjoining the hub) to cross the curb without violent impact against the first fixing means 11 in particular. As illustrated in [Fig. 3] in particular, preferably the reinforcement 15 extends so as to rise towards the rear, for example at an angle of substantially 45 degrees relative to the ground so as to avoid a sudden impact against such a projecting element 4 from the ground.Thus, the reinforcement 15 makes it possible to avoid a frontal impact against or at the level of the first fixing means 11.

[0035] Note that the element 4 may be, for example, an element of street furniture or a projection extending upwards from the roadway, in particular due to a hole or pothole in the roadway, for example.

[0036] Thanks to the solution, the steering knuckle 10 is reinforced and satisfies the impact resistance, in particular to impacts suffered in the lower part and in reverse, that is to say when moving backwards despite the geometry of the steering knuckle being unfavorable due to the first fixing means 11 arranged in an unprotected zone. Indeed, although the first fixing means 11 is outside the cylindrical space E of large radius RM present in the wheel 8 in the transverse, vertical and / or radial directions relative to the axis AP, the ramp 15 avoids any significant impact of the first fixing means 11. In addition, the reinforcement 15 is sufficiently strong to absorb the forces at this level. As mentioned previously, the ramp makes it possible to pass over the obstacle 4. In addition, the triangulation reinforces while allowing a saving of material so that the steering knuckle has a mass similar to or even lower than that of a steering knuckle of the state of the art.

[0037] Optionally, the solution is compatible for a vehicle having engines arranged within the wheels, for example in volume E, the reinforcement 15 of the stub axle 10 not encroaching into this volume.

[0038] Thanks to the reinforcement, the support 10 of the steering knuckle type resists the energy coming from an impact against an element 4 although the element 4 is generally anchored to the ground. The reinforcement 15 prevents any cracking or breakage of the steering knuckle and guides the steering knuckle, and consequently the wheel 8, over the obstacle 4. In other words, safety is ensured and any subsequent risk is eliminated. Thus, the area of ​​the steering knuckle comprising the first fixing means receiving, for example, the means for maintaining or stabilizing the vehicle relative to the ground, and / or a shock absorber and / or a steering element is reinforced. that the first fixing means 11 protrudes downwards, the steering knuckle is not fragile at this level. This avoids a crack or breakage or deterioration at this level of the steering knuckle, which is a guarantee of long-term safety because a user of the vehicle can hardly notice a problem at this location without a specific inspection under the vehicle.

[0039] Furthermore, any lack of parallelism of the wheelset concerned which could result from such an impact is avoided, as well as abnormal wear of the tire(s) where applicable.

[0040] As a remark, the solution therefore achieves the desired objective of allowing a fixing means arranged projecting downwards from a steering knuckle, and has the advantages of being able to be used on other types of vehicles, namely trucks, buses, buses, agricultural vehicles, lifting equipment and any other equipment.
