Definitions

  • Ground connection for a vehicle having a wheel and a suspension integrated in the wheel.
  • the present invention relates to the ground connection of motor vehicles. It relates in particular to the ground connection systems in which the vertical suspension uses a slide implanted inside the wheel.
  • An object of the invention is to provide a ground connection of the aforementioned type in which the weight-stiffness-bulk compromise is significantly improved.
  • the weight of a ground connection in particular the weight of its unsprung portion is an essential characteristic for the dynamic performance of the vehicle.
  • the mechanical rigidity of a ground connection is also an essential feature. Insufficient rigidity can have a negative effect on the quality of the guidance of the wheel plane but also adverse consequences on the service life of the elements of the ground connection, for example due to fatigue of the materials or wear due to friction caused by deformations. It is understood that the size is a particularly important aspect since a particular interest of this type of ground connection is to integrate all functions in the interior volume of the wheel.
  • a ground connection comprising a wheel, a wheel carrier, means for driving the wheel by at least one rotary motor secured to the wheel carrier, reduction means comprising at least one crown toothed gear connected to the wheel and at least one pinion connected to the rotary motor, a slider suspension of the wheel relative to a support connected to the vehicle, braking means, said braking means comprising a brake disk connected by its periphery to the wheel and a brake clamp disposed inside the brake disc.
  • the brake disc, the driving pinion and the ring gear are arranged substantially in the same plane.
  • the pinion and the ring gear have an oblique toothing, the pinion being guided relative to the wheel carrier by guide means independently of the axis of the rotary motor.
  • the guide of the rotating assembly comprising the wheel, the brake disc and the ring is provided by a pair of bearings preferably arranged around a male portion of the wheel carrier.
  • the slider suspension comprises a bar secured to the wheel carrier, the axis of the bar being positioned substantially on the axis of the wheel and substantially vertically in the central plane of the wheel, the degree of freedom of suspension of the wheel carrier relative to the chassis of the vehicle being allowed by the movement of the bar in guide means connected to the support.
  • the ground connection according to the invention further comprises an electromechanical machine for controlling suspension movements.
  • the electromechanical machine is advantageously a rotary machine integral with a suspension pinion, said pinion cooperating with a rack integral with the bar.
  • the ground connection further comprises a pivoting connection of the guide means relative to the support to allow the steering of the wheel about a pivot axis.
  • this pivot axis substantially corresponds to the axis of the bar.
  • FIG. 1 is a plan view along the axis of the wheel of a preferred embodiment of the ground connection according to the invention.
  • FIG. 2 is a sectional view in the vertical plane passing through the axis of the wheel of the embodiment of Figure 1 (A-A plane in Figure 1).
  • FIG. 3 is an axial half-section along line B-B of the embodiment of FIG. 1.
  • FIG. 4 is an axial half-section along the line C-C of the embodiment of FIG. 1.
  • Figure 5 is an exploded perspective view of the main elements of the ground connection of Figure 1.
  • FIG. 1 to 4 there is shown a wheel 1 assembled from a rim 2 and a wheel disk 3. There is shown a tire 4 mounted on the rim 2.
  • the wheel 1 is rotatably mounted around its axis 5 by means of bearings 6 on a ratchet 7.
  • the wheel carrier is secured to a substantially vertical bar 8.
  • the bar can slide along its axis 9 relative to a support 10 by means of guide means 11, for example rollers.
  • This movement corresponds to the deflection of suspension of the ground connection according to the invention.
  • the suspension movement is actively controlled by a rotary electromechanical machine 12.
  • the support 10 is intended to be connected to the vehicle body, either rigidly or by a connection allowing additional degrees of freedom such as a variation of the body height and / or wheel camber, vibration filtering or horizontal suspension.
  • the braking means comprise a brake disc 13 connected by its periphery to the wheel 1 and a clamp 14 integral with the ratchet 7 and disposed inside the brake disc 13.
  • the clip thus overlaps the disc of brake from the inside of it.
  • brake 13 is mounted "floating" on the wheel, that is to say that the connection between the brake disc and the wheel allows axisymmetric relative displacements especially in the radial direction. The amplitude of these displacements is limited to a few millimeters.
  • a floating assembly allows the thermal expansion of the disc and can also reduce the heat exchange between the wheel and the brake disc.
  • Figure 5 illustrates an embodiment of such an arrangement. In this figure, we see pins 27 secured to the wheel disc 3, these pins are housed in notches 26 of the brake disc 13.
  • the motorization of the vehicle is provided by drive means of the wheel comprising a rotary motor 15 mounted on the ratchet 7.
  • the motor 15 is an electric motor.
  • An electric motor can also be used as a retarder and allow to recover in electrical form part of the kinetic energy of the vehicle. In this case, the power of the mechanical braking means can be reduced.
  • Reduction means comprise at least one ring gear 16 connected to the wheel and at least one pinion 17 driven by the rotary motor 15.
  • One or more additional gear wheels may be interposed between the motor pinion 17 and the ring gear 16 either permanently to allow for further reduction, or in a controlled manner to offer a choice of reduction ratios.
  • the piece forming the ring 16 is also the hub on which the wheel is fixed.
  • the wheel bearings 6 are arranged in a bore of the central portion of the ring and the wheel is bolted on an axial extension 25 of this central portion.
  • the brake disc 13, the ring gear 16 and the pinion 17 are arranged substantially in the same plane, that is to say that their total size along the axis 5 of the wheel is substantially equal to the axial size of the widest element (here the pinion).
  • the bearings 6 are also arranged substantially in the same plane. It is understood that this advantageous arrangement in terms of axial space also allows a reduction in mass and / or an increase in rigidity.
  • the wheel holder 7 comprises a male portion around which are fitted the wheel bearings 6. Compared with the provision of the application EP 0878332 in which the wheel bearings are held in a central opening of the door -roue, the intrinsic rigidity of the guide wheel is substantially increased.
  • the guide pinion 17 is a function performed by the wheel carrier, for example by means of a pair of ball bearings 18 or roller.
  • the pinion is not carried by the axis of the motor 15 but has its own guide means.
  • the pinion remains of course driven by the axis of the motor, by means of connecting means such as complementary grooves known per se. In this way, irrespective of the intensity of the transmitted torque, the quality of engagement of the pinion with the ring gear remains satisfactory because it is not dependent on the rigidity or guidance of the motor shaft.
  • the pinion and the crown have an oblique toothing.
  • the guide means 11 of the bar 6 in translation are "frictionless", that is to say that they have as little friction as possible. Rolling guidance is very suitable. It is possible to use rollers 19 cooperating with runways arranged on the bar, the rollers being rotatably mounted on and with respect to the guide member. Relatively sliding contact surfaces could also be designed as long as they have a suitable treatment or if they are sufficiently lubricated. For example, a fluid bearing may be used.
  • a rotary electromechanical machine 12 which electromechanical machine acts via a suspension pinion (not shown) on a rack 21 secured to the bar 8
  • This arrangement has the advantage of being particularly well suited to the active control of suspension characteristics, and more specifically to direct electrical control.
  • a spring 22 acts between the wheel holder 7 and the guide means 11 to take up a portion and preferably the entirety of the static load of the vehicle.
  • the axis 9 of the bar is positioned substantially on the axis of the wheel 5 and substantially vertically in the central plane of the wheel, that is to say that the bar is perfectly centered relative to wheel.
  • the axis 9 of the bar also corresponds to the pivot axis.
  • the pivoting connection is provided by a set of conical bearings 23. These bearings allow rotation of the guide means 11 relative to the support 10 around the vertical pivot axis. When the pivot axis is thus positioned, the steering wheels only undergo very low steering moments due to the forces exerted by the ground.
  • the wheel holder 7 is a housing receiving the ring gear 16 and the pinion 17.
  • This housing is closed by a sealed cover 24 to isolate this gear.
  • the housing may contain a suitable lubricant.
  • This figure also shows the fitting of the pinion 17 on a pair of bearings 18 in said housing.
  • the wheel 1 is preferably assembled from a wheel disc 3 and a rim 2, both made of light alloy.
  • the rim is preferably monobloc, ie made in one piece.
  • the figures show the interest of the invention as to the mechanical size of the various elements.
  • the compactness of the ground connection according to the invention allows for example to use a sufficiently narrow wheel so that it does not come into contact with the sidewalks during parking maneuvers (see Figure T).
  • the advantage provided by the invention is also substantial. Indeed, one can compare the preferred embodiment of the patent application EP 0878332 (visible in Figures 1 and 2 of said application) to the preferred embodiment of the present application. While the travel of the suspension was increased from 145 mm to 170 mm and the diameter of the wheel was increased from 16 to 17 inches, there is a reduction of about 20% of the unsprung mass. In the various figures, it is recognized a tire 4 mounted on the rim 2 in a completely conventional manner. One could of course adopt other solutions, such as a tire permanently attached to its rim, or a non-inflated or non-pneumatic elastic bandage.
