Abstract

The wheel has a toothed wheel (18) attached to the hub. The toothed wheel meshes with two pinions (951,952) mounted in rotation on a wheel carrier (3). The rotation of these two pinions is controlled by two electric traction motors (971,972), with their rotors directly coupled to the pinions. The two motors operate in parallel, producing an additive torque at the wheel.

Description

La présente invention concerne la motorisation de véhicules au moyen deThe present invention relates to the motorization of vehicles by means of

moteurs intégrés dansmotors integrated in

les roues.the wheels.

On envisage de plus en plus de construire des véhicules à traction électrique, par exemple des véhicules urbains. Dans ce contexte, on a déjà proposé d'implanter le moteur électrique de traction directement dans la roue, afin de supprimer l'arbre de transmission. On sait en effet qu'un moteur électrique peut développer un couple important au démarrage, ce qui fait qu'il n'est pas nécessaire de prévoir de boîte de vitesse. La chaîne de transmission mécanique du couple moteur jusqu'à la roue s'en trouve simplifiée. Pour en tirer tout le bénéfice, il est judicieux d'implanter directement dans la roue ledit moteur. Cependant, on se heurte alors à d'autres difficultés: étant donné que le volume du moteur électrique est proportionnel au couple qu'il est capable de délivrer, pour que le moteur de traction puisse développer un couple suffisant, son volume sera important s'il entraîne la roue en direct. Cela n'est pas souhaitable car, outre les  There are increasing plans to build electric traction vehicles, for example urban vehicles. In this context, it has already been proposed to install the electric traction motor directly in the wheel, in order to remove the drive shaft. We know that an electric motor can develop a significant torque at start-up, which means that there is no need to provide a gearbox. This simplifies the mechanical transmission chain from engine torque to the wheel. To make the most of it, it is wise to install said motor directly in the wheel. However, we then come up against other difficulties: given that the volume of the electric motor is proportional to the torque that it is capable of delivering, so that the traction motor can develop sufficient torque, its volume will be significant if it drives the wheel live. This is not desirable because, in addition to the

problèmes d'encombrement, cela augmente à l'excès le poids des masses non suspendues.  congestion problems, this excessively increases the weight of unsprung masses.

Aussi, on a déjà proposé d'incorporer dans la roue un train épicycloïdal pour permettre au moteur électrique de tourner plus vite et démultiplier le couple qu'il produit. Cependant, la réduction de vitesse par train épicycloïdal cause par elle-même une surcharge dans la roue. D'o un rapport masse de l'ensemble roue et chaîne de traction par unité de puissance ou de couple  Also, it has already been proposed to incorporate into the wheel a planetary gear train to allow the electric motor to rotate faster and to increase the torque it produces. However, the reduction in speed by the planetary gear train by itself causes an overload in the wheel. This results in a mass ratio of the wheel and traction chain assembly per unit of power or torque

développé à la roue qui n'est pas beaucoup plus favorable.  developed at the wheel which is not much more favorable.

L'invention propose un élément de liaison au sol d'un véhicule automobile, ledit élément comportant un moyeu conçu pour supporter une roue, ladite roue comprenant essentiellement un disque et une jante, ledit ensemble comportant un porte-roue définissant l'axe de rotation du moyeu, ledit élément comportant une roue dentée solidaire du moyeu, ladite roue dentée étant en prise avec un pignon monté tournant sur le porte-roue, le mouvement dudit pignon étant commandé par au moins un moteur de traction dont le stator est solidaire du porte-roue, dont le rotor entraîne en prise directe ladite roue dentée, de façon à pouvoir appliquer un couple audit  The invention provides a ground connection element of a motor vehicle, said element comprising a hub designed to support a wheel, said wheel essentially comprising a disc and a rim, said assembly comprising a wheel carrier defining the axis of rotation. of the hub, said element comprising a toothed wheel secured to the hub, said toothed wheel being engaged with a pinion rotatably mounted on the wheel carrier, the movement of said pinion being controlled by at least one traction motor whose stator is integral with the carrier -wheel, the rotor of which directly drives said toothed wheel, so as to be able to apply a torque to said

moyeu via la roue dentée.hub via the gear wheel.

Les moteurs agissent en parallèle, les couples fournis par  -2- Preferably, several electric motors are used, all of which act directly on a toothed wheel concentric with the wheel. The motors operate in parallel, the torques provided by

chacun d'eux s'additionnant.each of them adding up.

L'invention sera mieux comprise par la description d'un exemple donné à titre non limitatif, en se  The invention will be better understood from the description of an example given without implied limitation, by

référant au dessin annexé sur lequel: la figure I est une vue partielle et coupe partielle selon I-I à la figure 2;  referring to the attached drawing in which: Figure I is a partial view and partial section on I-I in Figure 2;

la figure 2 est une vue partielle et coupe partielle selon II-II à la figure 1.  FIG. 2 is a partial view and partial section on II-II in FIG. 1.

Aux figures, on reconnaît un pneu I monté sur une jante 10. La jante 10 est reliée à un disque 13 de roue. La jante 10 et le disque 13 forment une roue 14. Cette roue 14 est montée sur un moyeu grâce à des goujons 16. Un disque de frein 17 est solidaire du moyeu 15. Les détails de réalisation du montage d'une roue et d'un disque de frein sur un moyeu sont bien connus de l'homme du métier et ne nécessitent pas de plus ample explication. Rappelons simplement qu'il peut exister une fixation assez faiblement dimensionnée entre le disque de frein 17 et le moyeu , et que la reprise des efforts de service est assurée par la fixation due aux goujons 16. Une roue dentée 18 est également solidaire du moyeu 15. Le moyeu 15 et la roue dentée 18 sont rendus solidaires l'un de l'autre par un ensemble de boulons 19, de façon à non seulement maintenir les pièces l'une sur l'autre, mais aussi assurer la transmission d'un couple entre la roue dentée 18 et le moyeu 15. Le sous-ensemble qui vient d'être décrit constitue les pièces dites  The figures show a tire I mounted on a rim 10. The rim 10 is connected to a wheel disc 13. The rim 10 and the disc 13 form a wheel 14. This wheel 14 is mounted on a hub by means of studs 16. A brake disc 17 is integral with the hub 15. The details of the mounting of a wheel and a brake disc on a hub are well known to those skilled in the art and do not require further explanation. Let us simply recall that there may be a fairly small dimensioned fixing between the brake disc 17 and the hub, and that the resumption of the service forces is ensured by the fixing due to the studs 16. A toothed wheel 18 is also integral with the hub 15 The hub 15 and the toothed wheel 18 are made integral with one another by a set of bolts 19, so as not only to hold the parts one on the other, but also to ensure the transmission of a torque between the toothed wheel 18 and the hub 15. The sub-assembly which has just been described constitutes the so-called parts

tournantes de la liaison au sol. Leur axe de rotation est l'axe XX'.  of the ground connection. Their axis of rotation is the XX 'axis.

Ces pièces tournantes sont montées sur un porte-roue 3 par l'intermédiaire d'un roulement 2. Le porte-roue 3 forme une bride insérée dans l'espace libre situé axialement entre le moyeu 15 et la  These rotating parts are mounted on a wheel carrier 3 by means of a bearing 2. The wheel carrier 3 forms a flange inserted in the free space located axially between the hub 15 and the

roue dentée 18. La bague extérieure du roulement 2 est solidaire du porte-roue 3.  toothed wheel 18. The outer ring of the bearing 2 is integral with the wheel holder 3.

Le porte-roue 3 est lui-même relié à la caisse du véhicule, dans cet exemple via un dispositif de  The wheel carrier 3 is itself connected to the vehicle body, in this example via a

suspension à bras superposés 4. On voit aussi une biellette de commande de direction 40.  suspension with superimposed arms 4. A steering control rod 40 is also seen.

Examinons l'implantation des moyens de freinage. Rappelons qu'un disque de frein 17 est solidaire du moyeu 15. L'effort de freinage est appliqué sur le disque de frein 17 par un étrier de frein 90 solidaire du porte- roue 3. L'étrier de frein 90 permet à la demande de pincer le disque de frein 17 par une commande appropriée, par exemple hydraulique ou électrique, ladite -3 - commande ne faisant pas partie en soi de la présente invention. Bien entendu, ce type de frein, à disque, n'est qu'une variante constructive et, plus généralement, l'invention peut utiliser des moyens de freinage comportant une pièce de révolution pourvue d'au moins une piste de freinage, ladite pièce de révolution étant solidaire du moyeu, et comportant un organe de freinage pour appliquer un matériau de friction sur ladite piste, ledit organe de freinage étant  Let us examine the location of the braking means. Recall that a brake disc 17 is secured to the hub 15. The braking force is applied to the brake disc 17 by a brake caliper 90 secured to the wheel carrier 3. The brake caliper 90 allows demand to apply the brake disc 17 by an appropriate control, for example hydraulic or electric, said control not forming in itself part of the present invention. Of course, this type of disc brake is only a constructive variant and, more generally, the invention can use braking means comprising a part of revolution provided with at least one braking track, said part of revolution being integral with the hub, and comprising a braking member for applying a friction material to said track, said braking member being

solidaire du porte-roue.secured to the wheel carrier.

La paroi interne 30 du porte-roue 3 comporte plusieurs zones d'ancrages 31 chacune prévue pour recevoir un moteur, donc comportant un orifice pour le passage de l'arbre du rotor et un ou des points de fixation pour le stator. En cas de non utilisation d'une ou de plusieurs desdites zones d'ancrage 31, on peut très facilement occulter ledit orifice correspondant par un couvercle d'occultation adapté à cet effet. Cela préserve l'isolation de la cavité interne, et empêche l'huile  The internal wall 30 of the wheel carrier 3 comprises several anchoring zones 31 each provided for receiving a motor, therefore comprising an orifice for the passage of the rotor shaft and one or more fixing points for the stator. If one or more of said anchoring zones 31 are not used, it is very easy to conceal said corresponding orifice by a concealment cover adapted for this purpose. This preserves the insulation of the internal cavity, and prevents the oil

qu'elle contient de s'échapper ou d'être polluée par des corps étrangers.  that it contains to escape or to be polluted by foreign bodies.

Dans l'exemple illustrant l'invention, le couple est fourni par deux moteurs intégrés à l'ensemble proposé par l'invention. Ce sont ici des moteurs électriques 971 et 972, dit de traction, dont les stators sont directement solidaires du porte-roue 3 (voir le stator 982 à la figure 2). Les rotors des moteurs 971 et 972 entraînent les pignons 951 et 952, eux mêmes étant en prise sur la roue dentée 18 S. Ces moteurs électriques 971 et 972 peuvent être pilotés non seulement pour appliquer un couple moteur, mais aussi un couple freineur à la roue dentée 18, donc au moyeu 15 et donc à la roue 14. On voit que l'on dispose de suffisamment de place pour loger plusieurs moteurs de traction, quel que soit le type de moteur (électrique, hydraulique par exemple). De préférence, on utilise des moteurs électriques de traction conçus pour une vitesse de rotation maximale élevée, ce qui à performances visées constantes, diminue le couple requis et donc diminue le volume du moteur. Cela contribue à la grande compacité de l'ensemble et facilite l'implantation et  In the example illustrating the invention, the torque is supplied by two motors integrated into the assembly proposed by the invention. These are electric motors 971 and 972, said to be traction motors, the stators of which are directly integral with the wheel carrier 3 (see stator 982 in FIG. 2). The rotors of the motors 971 and 972 drive the pinions 951 and 952, themselves being engaged on the toothed wheel 18 S. These electric motors 971 and 972 can be controlled not only to apply a motor torque, but also a braking torque to the toothed wheel 18, therefore at the hub 15 and therefore at the wheel 14. It can be seen that there is sufficient space to accommodate several traction motors, whatever the type of motor (electric, hydraulic for example). Preferably, electric traction motors are used which are designed for a high maximum rotational speed, which at constant targeted performances, decreases the required torque and therefore decreases the volume of the motor. This contributes to the overall compactness and facilitates the installation and
