Les figures 1 et 2 représentent deux vues de haut de principe de du châssis (10, 20) et de la direction selon l'invention. Le châssis comprend une plaque de châssis arrière (10) notamment supporté par le jeu de roues arrières (2) et une plaque de châssis avant (20) notamment supporté par le jeu de roues avant (3). La plaque de châssis arrière (10) reposant en contact sur la plaque de châssis avant (20) par l'entremise d'un jeu de quatre cales de glissement (30, 30a, 30b, 30c, 30d). Ces cales de glissement devant être au minimum au nombre de trois pour des raisons de stabilité et pouvant être sous d'autres formes d'un nombre supérieur à quatre, le principal étant de créer un liaison de glissement sur le plan horizontal entre la plaque de châssis arrière (10) et la plaque de châssis avant (20). De cette façon le véhicule, figure 2, tournera avec un jeu de roues avant (3). Les deux roues avant (3) étant indépendantes et pivotant chacune dans une direction fixe par rapport à la plaque de châssis avant (20). Sous une première forme les cales de glissement (30) sont des galets logés dans un creux de plaque de châssis avant (20). Sous une autre forme les cales de glissement (30) sont des sortes de balles de tennis qui outre le glissement amortissent les pressions entre la plaque de châssis arrière (10) et la plaque de châssis avant (20). Comme représenté en figure 6, l'ensemble des deux plaques de châssis (10, 20) coopérant et supportant le caisson d'habitacle (50). La figure 3 représente une vue de profil du châssis selon l'invention qui montre comment les plaques de châssis avant (20) et arrière (10) reposent l'une sur l'autre en contact par des cales de glissement (30) selon un plan horizontal parallèle au plan des deux plaques de châssis avant et arrière (10, 20). Les deux plaques de châssis (10, 20) étant également lié par une liaison pivot (38) à axe vertical matérialisé par exemple par un axe de rotation maintenu par chacune des deux plaques et par des liaisons de maintien de distance (139) entre les deux plaques. Les liaisons de maintien de distance (139) sont par exemple matérialisés par une pièce métallique rigide positionnée de façon fixe sur le dessus de la plaque avant de châssis (20) au niveau en vue de dessus de la position de la limite de la plaque arrière (10) et positionnée de façon libre juste au dessus de la plaque arrière (10). La pièce métallique présentant ainsi en vue de dessus une forme d'arc circulaire et en coupe une forme à trois côtés, un côté de fixation sur la plaque avant, un côté de maintien de distance et un côté d'affleurement au dessus de la plaque arrière. La figure 4 représente en vue de haut un schéma de principe de la mécanique de direction dans lequel la plaque avant pivote autour de la plaque arrière autour de la liaison pivot (38) à une distance de direction CD). Cette distance de direction (D) étant positionné en seconde extrémité sur la liaison de direction (34,35) qui consiste comme représenté en figure 5 dans la combinaison d'un pignonFigures 1 and 2 show two views of the principle principle of the frame (10, 20) and the direction according to the invention. The chassis comprises a rear chassis plate (10) in particular supported by the set of rear wheels (2) and a front chassis plate (20) in particular supported by the set of front wheels (3). The rear frame plate (10) is in contact with the front frame plate (20) through a set of four slip blocks (30, 30a, 30b, 30c, 30d). These sliding shims must be at least three in number for reasons of stability and which can be in other forms of a number greater than four, the main one being to create a sliding connection on the horizontal plane between the plate of rear frame (10) and the front frame plate (20). In this way the vehicle, figure 2, will turn with a set of front wheels (3). The two front wheels (3) being independent and each pivoting in a fixed direction relative to the front frame plate (20). In a first form, the sliding wedges (30) are rollers housed in a front frame plate recess (20). In another form the slip wedges (30) are kinds of tennis balls which in addition to sliding cushion the pressures between the rear frame plate (10) and the front frame plate (20). As represented in FIG. 6, the assembly of the two frame plates (10, 20) cooperating and supporting the passenger compartment box (50). FIG. 3 shows a profile view of the frame according to the invention which shows how the front (20) and rear (10) frame plates rest one on the other in contact by sliding wedges (30) according to a horizontal plane parallel to the plane of the two front and rear frame plates (10, 20). The two frame plates (10, 20) are also connected by a pivot connection (38) with a vertical axis embodied for example by an axis of rotation maintained by each of the two plates and by distance maintaining links (139) between two plates. The distance maintaining links (139) are for example materialized by a rigid metal piece fixedly positioned on the top of the front plate of the frame (20) in a top view of the position of the limit of the rear plate. (10) and freely positioned just above the back plate (10). The metal piece thus having a circular arc shape and a three-sided shape in plan view, a fixing side on the front plate, a distance holding side and a flush side above the plate back. FIG. 4 shows in a top view a schematic diagram of the steering mechanism in which the front plate pivots around the rear plate around the pivot connection (38) to a steering distance CD). This steering distance (D) being positioned at the second end on the steering link (34,35) which consists as shown in FIG. 5 in the combination of a pinion
(34) circulant sur une chaîne (35). Cette liaison de direction (34, 35) représentant le point qui détermine l'angle de braquage de la plaque de châssis avant (20) en positionnant la liaison de direction (34,35) sur une position angulaire particulière selon le chemin de chaîne (35) qui déterminera ainsi un angle particulier de braquage de la plaque de châssis avant (20). L'utilisateur au moyen de son volant (40) et à travers les commandes de direction (41) faisant circuler le pignon de direction (34) solidarisé à la plaque arrière de châssis (10) sur la chaîne de direction(34) circulating on a chain (35). This steering linkage (34,35) represents the point which determines the steering angle of the front chassis plate (20) by positioning the steering link (34,35) at a particular angular position along the chain path ( 35) which will thus determine a particular steering angle of the front chassis plate (20). The user by means of its steering wheel (40) and through the steering controls (41) circulating the steering pinion (34) secured to the chassis rear plate (10) on the steering chain
(35) solidarisée sur la plaque de châssis avant (20) et détermine ainsi l'angle relatif de la plaque de châssis avant (20) par rapport à le plaque de châssis arrière (10) qui pivote autour de la liaison pivot (38), maintenue avec une distance fixe entre les deux plaques de châssis au moyen de la combinaison de liaison de glissement (30) et de liaison de maintien (139) de distance verticale entre les deux plaques horizontales. La plaque avant de châssis (20) pouvant atteindre un angle de braquage maximum (A) par rapport à la plaque arrière de châssis (10).(35) secured to the front frame plate (20) and thereby determines the relative angle of the front frame plate (20) relative to the rear frame plate (10) which pivots about the pivot link (38) , maintained with a fixed distance between the two frame plates by means of the sliding connection combination (30) and holding connection (139) of vertical distance between the two horizontal plates. The chassis front plate (20) can reach a maximum steering angle (A) relative to the chassis rear plate (10).
