Abstract

The device consists of a spring-loaded thrust disc (5) which is pressed towards a second disc (7) on the end of a sleeve (2) surrounding the steering shaft (1). The two discs are engaged through balls which sit in hemispherical recesses in one disc and engage with radial ribs on the other, the number of recesses and ribs being equal, so that each ball lies between two ribs. In the normal position the sleeve and discs rotated together with the steering shaft, while in the locked position the sleeve is held still by the locking mechanism bolt. When the steering wheel is turned one disc can rotate relative to the other only by the balls overcoming the pressure of the spring to pass over the ribs and preventing normal steering.

Description

La présente invention a trait d'une manière générale à des dispo sitifs en vue de limiter la rotation d'un arbre, et plus particulièrement à des dispositifs destinés à rendre impossible la conduite d'un véhicule automobile en interdisant la rotation normale du volant qui commande l'orientation des roues, lorsque l'antivol est en position active. The present invention relates generally to devices for limiting the rotation of a shaft, and more particularly to devices intended to make driving a motor vehicle impossible by preventing normal rotation of the steering wheel which controls the orientation of the wheels, when the lock is in the active position.

Des dispositifs antivol de ce type général existent selon de nom breuses réalisations et sont utilises pour empêcher l'orientation des roues. Une caractéristique commune à la plupart des dispositifs anti vol connus agissant sur la direction est qu'ils assurent le blocage definitif de la tige de direction, cette disposition présente certains avantages, mais est egalement désavantageuse au moins selon un aspect. Anti-theft devices of this general type exist in many ways and are used to prevent the orientation of the wheels. A characteristic common to most of the known anti-theft devices acting on the steering is that they ensure the definitive blocking of the steering rod, this arrangement has certain advantages, but is also disadvantageous at least in one aspect.

Ceci, parcequ'un couple violent appliqué sur le volant peut provoquer la rupture des fixations de l'antivol, rendant celui-ci inopérant et permettant à nouveau aux roues de s'orienter normalement.This is because a violent torque applied to the steering wheel can cause the locks of the locks to break, rendering the lock inoperative and allowing the wheels to orient themselves normally.

Dans le dispositif antivol selon l'invention, disposition est prise pour permettre de contrarier la rotation de la tige de direction sans qu'un effort violent puisse provoquer la rupture de quelque élé ment que ce soit. I1 comporte en effet selon une première caractéris tique, une tige de direction munie d'un noyau à cames multiples incor poré, entre deux cames duquel va se placer le pène d'un antivol de type à blocage de direction, ce pène pourra éventuellement être usiné pour s'appliquer avec plus de précision sur les pentes des cases et il va empêcher la rotation de la tige de direction tant qu'un couple à valeur prédéterminé n'aura pas été appliqué sur le volant,pour permettre au pène de repousser son ressort interne et de franchir les cames successives qui contrarient sa rotation, ce qui rendra toute conduite impossible. In the anti-theft device according to the invention, provision is made to allow the rotation of the steering rod to be countered without a violent force being able to cause the rupture of any element whatsoever. In fact, according to a first characteristic, it comprises a steering rod provided with a built-in multiple cam core, between two cams of which the bolt of an anti-theft device of the steering lock type will be placed, this bolt may possibly be machined to apply more precisely on the slopes of the boxes and it will prevent the rotation of the steering rod until a torque of predetermined value has not been applied to the steering wheel, to allow the bolt to push its internal spring and to cross the successive cams which counteract its rotation, which will make any driving impossible.

Selon des modes particuliers de réalisation:
- On pourra utiliser un noyau à cames rapporté, maintenu par un têton de blocage qui prendra place dans une lumière de la tige de direction.According to particular embodiments:
- We can use an added cam core, held by a locking pin which will take place in a slot in the steering rod.

- Un manchon élastique muni de bossages qui s'effaceront sur les cames à la place du pène, lequel prendre place dans une lumière, pourra être ajusté sur le noyau pour augmenter le diamètre de l'ensemble.  - An elastic sleeve provided with bosses which will be erased on the cams in place of the bolt, which take place in a light, can be adjusted on the core to increase the diameter of the assembly.

L'invention est décrite ci-après à l'aide d'un exemple et de réfé rences aux dessins joints, dans lesquels:
La figure 1 représente une perspective de la tige de direction avec son noyau à cames incorporé.The invention is described below using an example and references to the accompanying drawings, in which:
Figure 1 shows a perspective of the steering rod with its incorporated cam core.

La figure 2 représente une coupe transversale de la colonne de di rection complète, au niveau de l'axe de coupe x-y de la figure 1. FIG. 2 represents a cross section of the complete steering column, at the level of the cutting axis x-y of FIG. 1.

La figure 3 représente une perspective de la tige de direction avec un noyau à cames rapporté. Figure 3 shows a perspective of the steering rod with an attached cam core.

La figure 4 représente une variante du noyau à cames rapporté muni d'un manchon élastique. FIG. 4 represents a variant of the attached cam core provided with an elastic sleeve.

En référence à ces dessins, le dispositif comporte une tige de di rection (1) munie d'un noyau à cames multiples (2) qui recevra dans la partie inférieure réalisée entre deux cames adjacentes, le pène (3) d'un antivol de type à blocage de direction C, qui empêchera la rota tion de la dite tige de direction lorsqu'un couple normal sera appliqué sur le volant.Sous l'effet d'un couple plus important dont la valeur sera prédéterminée, l'extrémité du pène (3) va glisser sur la courbe ascendante de l'une ou de l'autre des cames adjacentes, repousser son ressort, suivre la courbe supérieure de la came qui l'aura poussé, pour retomber dans la partie inférieure des cames suivantes, ce qui necessitera un nouvel effort important pour un nouveau déplacement infime des roues, rendant ainsi la conduite du véhicule impossible et interdisant toute détérioration. With reference to these drawings, the device comprises a steering rod (1) provided with a multiple cam core (2) which will receive, in the lower part produced between two adjacent cams, the bolt (3) of a lock for steering lock type C, which will prevent the rotation of the said steering rod when a normal torque is applied to the steering wheel. Under the effect of a greater torque whose value will be predetermined, the end of the bolt (3) will slide on the ascending curve of one or the other of the adjacent cams, push back its spring, follow the upper curve of the cam which will have pushed it, to fall back into the lower part of the following cams, this which will require a new significant effort for a new tiny displacement of the wheels, thus making the driving of the vehicle impossible and preventing any deterioration.

Dans le mode de réalisation selon la figure 3, le noyau rapporté (4) est réalisé sous forme d'un fourreau à cames multiples muni d'un ergot intérieur (5) qui viendra se bloquer dans une gorge (6) sur la tige de direction. In the embodiment according to FIG. 3, the added core (4) is produced in the form of a multiple cam sleeve with an internal lug (5) which will be blocked in a groove (6) on the rod. direction.

Selon une variante représente par la figure 4, un manchon élastique (7) pourra être place sur le noyau à cames incorporé ou rapporté, il comportera un ou plusieurs bossages (8) qui prendront place dans un ou plusieurs creux des cames du noyau, pour contrarier la rotation du dit noyau. Dans ce cas, le pène de l'antivol à blocage de direction viendra se placer dans une lumière (9)"du manchon élastique. According to a variant shown in Figure 4, an elastic sleeve (7) can be placed on the cam core incorporated or attached, it will include one or more bosses (8) which will take place in one or more recesses of the cams of the core, for to counteract the rotation of said core. In this case, the bolt of the anti-theft steering lock will be placed in a hole (9) "in the elastic sleeve.

Le dispositif selon l'invention est particulièrement destine à améliorer un antivol à blocage de direction sur les véhicules automobiles.  The device according to the invention is particularly intended to improve a steering lock anti-theft device on motor vehicles.
