Abstract

Device which can be fitted to any automotive or towed vehicle comprising a guide 1 with grooves 2 connected to a steering box 3. This guide which is inserted into a casing with balls 4 and is connected to the wheel pivot also comprises grooves on the walls of its hollow part. The insertion of balls 5 in the complementary grooves of the guide and of the casing allow sliding of the casing in the direction of the guide whilst rendering the guide and the casing securely fastened in the rotational direction. The possibility of sliding in the direction of the guide makes it possible to conserve the basic parallelism of the wheels, regardless of the variation in ground clearance or the amount by which the terrain is not level.

Description

Ia présente invention concerne un mécanisme de direction, permettant de conserver le parallélisme initial des roues, en cas de variation de hauteur du véhicule ou engin, ou dénivelée de terrain. Ia present invention relates to a steering mechanism, to maintain the initial parallelism of the wheels, in case of variation in height of the vehicle or machine, or uneven terrain.

Le parallelisme des roues d'une même train est caractérisé essentiellement par le pincement ou l'ouverture des roues du train
Le pincenert ou ltouverture est la différence de distance entre d'une part les bords avants, et d'autre part les bords arrières des jantes de deux roues du même train.The parallelism of the wheels of the same train is essentially characterized by the pinching or opening of the wheels of the train
The pincenert or the opening is the difference in distance between on the one hand the front edges, and on the other hand the rear edges of the rims of two wheels of the same train.

Dans les systèmes traditionnels , le mécanisme de direction ne permet pas de conserver le parallélisme initial des roues d'un même train lors d'un grand débattement ou en cas de dénivelée de terrain . En effet, les roues sont, soit reliées entre elles par une barre d'accouplement, soit reliées à une crémaillère ou boîtier de direction par l'intermédiaire d'une barre de direction. Les dites barres d'accouplement ou de direction rendent les roues solidaires 1 'une de l'autre et les font incliner de manière symétrique à claque variation de niveau du terrain. In traditional systems, the steering mechanism does not allow the initial parallelism of the wheels of the same train to be maintained during a long travel or in case of uneven terrain. Indeed, the wheels are either connected together by a tie rod, or connected to a rack or steering box via a steering bar. Said tie rods or steering rods make the wheels integral with one another and cause them to tilt symmetrically with each variation in level of the ground.

En outre, en ce qui concerne les véhicules ou engins à hauteur variable, les barres de direction traditionnelles ne permettent pas de conserver le parallélisme que les roues ont lorsque le véhicule est en position normale de base. In addition, with regard to vehicles or machines with variable height, traditional steering bars do not allow the parallelism that the wheels have to be maintained when the vehicle is in the normal basic position.

Le dispositif de l'invention permet de remédier à ces inconvénients. The device of the invention overcomes these drawbacks.

Selon l'invention, le dispositif comprend iii guide vertical avec rainures qui est fixe et relié en sa partie supérieure à la cremaillere ou boitier de direction par l'intermédiaire d'une biellette de façon à pouvoir être entrainé en rotation par la direction , ce guide étant insére dans un boitier à billes, également à rainures apte à coulisser le long du guide et à tourner avec lui, ce boitier étant en outre solidaire du portefusée de roue, le boitier à billes étant donc capable d'un glissement vertical dans le sens des rainures sur le guide mais réalisant une solidarité des mouvements de rotation du guide et du boîtier, quelle que soit la position de ce boitier sur le guide. According to the invention, the device comprises iii vertical guide with grooves which is fixed and connected in its upper part to the rack or steering box by means of a link so as to be able to be rotated by the steering, this guide being inserted in a ball housing, also with grooves able to slide along the guide and to rotate with it, this housing being also integral with the wheel hub, the ball housing therefore being capable of vertical sliding in the direction of the grooves on the guide but achieving a solidarity of the rotational movements of the guide and of the housing, whatever the position of this housing on the guide.

Ce dispositif est représenté en coupe sur les figures (1) (2) et (3) . I1 comporte les éléments suivants
1) un support (1) fixé au chassis ou à la caisse du véhicule qui tient en sa partie supérieure un guide vertical (2) de section cylindrique avec rainures de forme concave (3) (figure 4! faisant chemin de roulement dans le sens du guide
2) le guide est en sa partie supérieure relié à une cremaillere ou un boitier de direction.This device is shown in section in Figures (1) (2) and (3). I1 contains the following elements
1) a support (1) fixed to the chassis or to the body of the vehicle which holds in its upper part a vertical guide (2) of cylindrical section with concave grooves (3) (Figure 4! Running in the direction of travel of the guide
2) the guide is in its upper part connected to a rack or a steering box.

3) un support guide (4) fixé au porte fusée ou au porte moyeu (5) tient le guide en sa partie inférieure. 3) a guide support (4) fixed to the stub axle carrier or to the hub carrier (5) holds the guide in its lower part.

4) un boîtier à billes (6) (figure 5) de forme cylindrique creuse destinée à recevoir le guide (2) comportant sur les parois de sa partie creuse des rainures verticales concaves (7) (figure 5) disposées de manière opposée et complémentaire aux rainures (3) (figure 4) du guide
Le boitier à billes comporte une biellette (8) qui fait corps avec lui et qui est reliée par une barre de liaison (9) à la biellette de la fusée (10). 4) a ball housing (6) (figure 5) of hollow cylindrical shape intended to receive the guide (2) comprising on the walls of its hollow part concave vertical grooves (7) (figure 5) arranged in an opposite and complementary manner to the grooves (3) (figure 4) of the guide
The ball housing includes a link (8) which is integral with it and which is connected by a connecting bar (9) to the rocket link (10).

5) les billes (11 - figure 3) qui épousent la forme cylindrique complète des rainures du guide (2) et des rainures du boitier (6) placées en vis-à-vis, sont insérées dans les formes cylindriques creuses représentées par ces doubles rainures. 5) the balls (11 - Figure 3) which conform to the complete cylindrical shape of the grooves of the guide (2) and the grooves of the housing (6) placed opposite, are inserted into the hollow cylindrical shapes represented by these double grooves.

Du fait de l'insertion des billes dans les rainures, le guide et le boîtier deviennent solidaires dans le sens de la rotation, mais le boîtier peut glisser le long du guide dans le sens vertical
Cette possibilité de glissement vertical le long du guide permet de conserver le parallélisme de base des roues du train dans n'importe quelle variation de celles-ci, et en particulier en cas de dénivelée du terrain ou augmentation de la garde au sol par utilisation d'uc système de suspension à hauteur variable.Due to the insertion of the balls in the grooves, the guide and the housing become integral in the direction of rotation, but the housing can slide along the guide in the vertical direction
This possibility of vertical sliding along the guide makes it possible to maintain the basic parallelism of the wheels of the train in any variation of these, and in particular in the event of uneven terrain or increased ground clearance by using 'uc adjustable height suspension system.

Par contre le mouvement de rotation du guide imprimé par la crémaillère ou boitier de direction entraine un mouvement de rotation du boitier à billes , lequel relié à la fusée, fait pivoter la roue. On the other hand, the movement of rotation of the guide printed by the rack or steering box causes a movement of rotation of the ball housing, which connected to the rocket, makes the wheel pivot.

les figures (1) et (2) représentent en coupe, le dispositif selon l'invention. Figures (1) and (2) show in section, the device according to the invention.

Les figures (3) ,(4) et (5) représentent les coupes du boitier à billes du guide et des billes. Figures (3), (4) and (5) show the sections of the guide ball housing and the balls.

l'a figure (6) représente en ccupe le véhicule en position normale. Figure (6) shows in ccupe the vehicle in normal position.

La figure (7) représente en coupe, une variante de ce dispositif dans lequel du fait d'une augmentation de la garde au sol le boitier à billes est positionné à la partie supérieure du guide, ce qui permet de constater que le parallélisme de la roue n'a pas varié. Figure (7) shows in section, a variant of this device in which due to an increase in ground clearance the ball housing is positioned at the top of the guide, which shows that the parallelism of the wheel did not change.

L'invention sus-visée pourrait être utilisée particulièrement pour les engins tous terrains et vehicules à hauteur variable.  The above invention could be used particularly for all terrain vehicles and variable height vehicles.
