Cependant le coulisseraient des tubes de suspension nécessite un angle d'inclinaison par rapport au sol face à un obstacle ainsi que pour la stabilité de la motocyclette ; d'autre part le coulissement des tubes dans le plan vertical par rapport au sol se trouve freiné par l'inclinaison de ces tubes nécessitant dans ce cas pour un bon coulissement qu'ils soient perpendiculaires au sens de la force. D'où une contradiction mécanique évidente. La présente invention a pour but de remédier à ces inconvénients et concerne à cet effet un dispositif de suspension de roue pour véhicules mobiles et véhicules mobiles munis de ce dispositif, notamment pour motocyclettes comprenant un ou deux dispositifs pouvant être montés de façon symétrique de part et d'autre de la roue et être reliés ensemble afin de ne comporter qu'un seul élément de suspension. Chaque dispositif comprenant une première liaison fixée à l'axe de rotation de la roue reliant par son extrémité libre articulée une seconde liaison ; cette
première, liaison recevant également l'extrémité oscillante d'une troisième liaison en un point fixe situé entre les deux extrémités de l'axe longitudinal de la première liaison reliant de manière articulable une quatrième liaison reliant de manière articulable l'exτrémité libre de la seconde liaison ; l'ensemble formant un parallélogramme déformable, la3ème ou, 4ème liaison recevant entre ses extrémités ou au-delà de celles-ci sur son axe ou au dehors de son axe longitudinal une extrémité d'un élément de suspension articulé, dispositif caractérisé en ce que le cadre ou châssis du véhicule reçoit en un point fixe directement ou indirectement par le biais d'un montage pivotant l'articulation d'un élément de suspension reliant un parallélogramme articulé et oscillable et reçoit également pour sa commande,, en un point fixe au-delà de l' axe d ' articulation de l' élément de suspension le parallélogram me en un point fixe articulé d'une des liaisons entre, avec ou au delà de son axe d'articulation par son prolongement.The suspension devices produced so far on the front of motorcycles generally consist of two suspension tubes directly connecting the axis of the steering wheel to the frame or chassis of the motorcycle indirectly by means of mounting on the 'pivoting axis of direction secured to the frame or chassis of the motorcycle by the steering column supporting the pivoting axis. However the sliding of the suspension tubes requires an angle of inclination relative to the ground facing an obstacle as well as for the stability of the motorcycle; on the other hand the sliding of the tubes in the vertical plane relative to the ground is braked by the inclination of these tubes requiring in this case for good sliding that they are perpendicular to the direction of the force. Hence an obvious mechanical contradiction. The object of the present invention is to remedy these drawbacks and to this end relates to a wheel suspension device for mobile vehicles and mobile vehicles provided with this device, in particular for motorcycles comprising one or two devices which can be mounted symmetrically on the side and on the other side of the wheel and be connected together so as to have only one suspension element. Each device comprising a first link fixed to the axis of rotation of the wheel connecting by its articulated free end a second link; this first, link also receiving the oscillating end of a third link at a fixed point located between the two ends of the longitudinal axis of the first link connecting in an articulated way a fourth link connecting in an articulated way the free end of the second liaison; the assembly forming a deformable parallelogram, the 3rd or 4th connection receiving between its ends or beyond these on its axis or outside its longitudinal axis one end of an articulated suspension element, device characterized in that the frame or chassis of the vehicle receives at a fixed point directly or indirectly by means of a pivoting assembly the articulation of a suspension element connecting an articulated and oscillable parallelogram and also receives for its command, at a fixed point at beyond the axis of articulation of the suspension element the parallelogram me at a fixed point articulated with one of the connections between, with or beyond its axis of articulation by its extension.
