Abstract

Device allowing steering in the hub of the wheel of a two-wheeled vehicle. If required, this device allows a system to be inserted for adjusting simultaneously or independently the caster and the caster angle. It is made up of a pivot 4 which can move in the region of its rotation axis 1 with respect to the hub 3 supporting the rolling-contact bearings 18 for the rotation of the wheel 7. Appended systems allowing the various parameters making up a two-wheeled vehicle of the moped type to be varied, eg.: caster, caster angle, wheel base, centre of gravity, distribution of masses, anti-dive effect, chain effect etc.

Description

DESCHIPTION
La presente invention concerne un système permettant la direction dans le moyeu de la roue avant d'un deux roues ( exerle motocyolette ) ou d'un side car avec la possibilite de règler independamment ou simultanement la chasse et l'angle de chasse, voir de simplifier le système pour une utilisation fixe et inderèglable.DESCHIPTION
The present invention relates to a system allowing the steering in the hub of the front wheel of a two wheel (exerle motocyolette) or a side car with the possibility of independently or simultaneously adjusting the hunting and hunting angle, see simplify the system for fixed and foolproof use.

Dans les dispositifs connus , la chasse n'est pas réglable et elle est importante pour un argle de chasse approprié car l'axe de direction est confondu avec l'axe de l'angle de chasse passant par l'axe de rotation de la roue avant; ou alors le système fait appel à un pivot avec fusée du type automobile ce qui interdit toute utilisation d'un bras oscillant double et symetrique à l'avant
Le sispositif suivant l'invention permet de remédier à cette lacune. Dans celui-ci en effet l'axe de rotation de la roue avant ( A ) peut être avance ou reculé à volonté par rapport à l'axe de direction ( C ). Pour cela le pivot de direction ( I-4 ) est loge à l'interieur du moyeu ( 3 ) , des roulements (Io ) permet- tant la rotation du moyeu ( 8 ) .Le braquage de la roue est possiDle grace à l'espace laisse entre l'intérieur des roulements 18 ) et le oras de pivot ( 4 ).In known devices, the flush is not adjustable and is important for a suitable hunting angle because the steering axis is coincident with the axis of the hunting angle passing through the axis of rotation of the wheel. before; or else the system uses a pivot with automobile type rocket which prevents any use of a double and symmetrical swing arm at the front
The device according to the invention makes it possible to remedy this shortcoming. In it in fact the axis of rotation of the front wheel (A) can be moved forward or backward at will relative to the steering axis (C). For this the steering pivot (I-4) is housed inside the hub (3), bearings (Io) allowing the rotation of the hub (8). The steering of the wheel is possible thanks to the space left between the inside of the bearings 18) and the pivot oras (4).

Le système permet le réglage simultané ou separe de la chasse et de l'angle de chasse. La chasse se règlant par deplacement de l'axe (I) dans le moyeu (3). Un axe ae direction (I) deporte en arrière par rapport à l'axe (2) du pivot (4) la distance wC est règlable, L'angle ae chasse est règlable ou modifiable par rotation de l'axe (2). Le mouvement est contrôlé par une jambe de force (10) ertioulé a ses extremites et moaifiable en longueur. The system allows simultaneous or separate adjustment of the flush and the flush angle. The flush is regulated by displacement of the axis (I) in the hub (3). An axis ae direction (I) deport back relative to the axis (2) of the pivot (4) the distance wC is adjustable, The angle ae flush is adjustable or modifiable by rotation of the axis (2). The movement is controlled by a strut (10) ertioulé at its ends and changeable in length.

La direction quant a elle est assure depuis les guidons (Ia) par l'intermediaire de z triangles (II) et (Id) superposes du type train d'attérissage d'avion, avec la particularité que ces 2 triangles (11) et (12) pourront avoir des dimensions identiques ou differentes, afin de pouvoir cotenir des systèmes qui dans leurs mouvements ne gênaront pas l'agencement d'accessoires ( ex : radiateurs d'eau ou d'huile, phare, carenage etc....). ces triangies pourront s'artiouler (13) en avant ou en arrière par rapport à l'axe de direction (G)
Le dispositif (moyeu o) peut être realise en deux ou plusieur parties reliees par des vis ou autre système d'assenblage afin de faliciter le montage et le denontage de l'ensemble.L'ouverture du moyeu (8) permet d'utiliser un pivot (4) dote d'axe (1) olus grend que la dimension laissee par l'alesage des roulementws (10) l'axe de direction (I) etant introduit par l'exterieur dans le sens du prolonge;nent de l'axe (I). The direction as for it is ensured from the handlebars (Ia) by the intermediary of z triangles (II) and (Id) superimposed of the aircraft landing gear type, with the particularity that these 2 triangles (11) and ( 12) may have the same or different dimensions, in order to be able to accommodate systems which in their movements do not interfere with the arrangement of accessories (ex: water or oil radiators, headlight, fairing, etc.) . these triangles can be articulated (13) forwards or backwards with respect to the steering axis (G)
The device (hub o) can be made in two or more parts connected by screws or other assembling system in order to simplify the assembly and disassembly of the assembly. The opening of the hub (8) allows the use of a pivot (4) has an axis (1) olus grend that the dimension left by the bore of the bearings ws (10) the steering axis (I) being introduced from the outside in the direction of the extension; axis (I).

En utilisant des lumières, des glissières ou des excentriques en (A), () le dispositif permet de faire varier l'inclinaison du bras oscillant avant, donc de modifier les reactions du train avant au freinage en produisant un phenomene d'anti-plongée contrôlable lors des transferts de masse pour les accelérations négativers ou positives. By using lights, slides or eccentrics in (A), () the device makes it possible to vary the inclination of the front swingarm, therefore to modify the reactions of the front axle under braking by producing an anti-dive phenomenon controllable during mass transfers for negative or positive accelerations.

L'empatement et le centre de gravité du véhicule sont modi- fiables par deplacements longitudinaux en utilisant des glissières et aes excentriques su l'axe de roue avant (A), l'axe de bras osoillant avant (E), l'axe de bras osoillant avent (F), l'axe de roue arrière (G) permettant aussi de faire varier le comportement du vehicule par modification ae sa longueur et de la répartition de ses masses  The wheelbase and center of gravity of the vehicle can be modified by longitudinal displacements using slides and eccentric on the front wheel axle (A), the front link arm axis (E), the axis of venting arm advent (F), the rear wheel axle (G) also making it possible to vary the behavior of the vehicle by modifying its length and the distribution of its masses
