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 disposi tifs en vue de limiter la rotation d'un arbre, et plus particulière ment à des dispositifs destinés à rendre impossible la conduite d'un véhicule automobile, en interdissant 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 that controls the orientation of the wheels, when the lock is in the active position.

Des dispositifs de ce type général existent selon de nombreuses réac lisations et sont utilisés pour empêcher l'orientation des roues.Une caractéristique commune à la plupart des dispositifs antivol connus agissant sur le direction est qu'ils assurent le blocage définitif de la tige de direction, cette disposition présente certains avantages, mais est également désaventageuse au moins selon un aspect, ceci parce qu'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. 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 final locking of the steering rod. , this arrangement has certain advantages, but is also disadvantageous at least in one aspect, this because a violent torque applied to the steering wheel can cause the locks of the locks to break, making it inoperative and allowing the wheels again to orient themselves normally.

Dans le dispositif antivol selon l'invention, disposition est prise pour contrarier la rotation de la tige de direction sans qu'un effort violent puisse provoquer la rupture de quelque élément que ce soit. I1 comporte selon une première caractéristique une tige de direction sur laquelle est fixé un disque qui sert d'appui à un ressort punissant, lequel exerce sa pression sur le rebord d'un manchon lui-même appuyé au disque par le rebord usiné de son extrémité opposée à travers trois billes fortement appliquées dans des alvéoles. In the anti-theft device according to the invention, provision is made to counter the rotation of the steering rod without a violent force being able to cause the rupture of any element whatsoever. I1 comprises according to a first characteristic a steering rod on which is fixed a disc which serves as a support for a punishing spring, which exerts its pressure on the rim of a sleeve itself supported on the disc by the rim machined from its end opposite through three balls strongly applied in cells.

Le pêne d'un antivol de type à blocage de direction vient se positionner dans une lumière du manchon qu'il immobilise empochant ainsi la rotation de la tige de direction et l'orientation des roues, lorsqu'un couple normal est appliqué sur le volant. Sous l'effet d'un couple plus important déterminé par le ressort, les billes vont se dégager de leurs alvéoles qu'elles vont franchir comme autant de cames, pour retomber dans les alvéoles suivantes, qui contrarient la rotation, rendant la conduite du véhicule équipé impossible. The bolt of a steering lock type anti-theft device is positioned in a lumen of the sleeve which it immobilizes, thus pocketing the rotation of the steering rod and the orientation of the wheels, when a normal torque is applied to the steering wheel. . Under the effect of a greater torque determined by the spring, the balls will disengage from their cells which they will cross like as many cams, to fall back into the following cells, which counteract the rotation, making the driving of the vehicle equipped impossible.

Selon un mode particulier de réalisation, les billes p ument etre remplacées par des nervures et les logements des billes par des rainures. According to a particular embodiment, the balls can be replaced by ribs and the ball housings by grooves.

Les dessins annéxés illustrent l'invention.  The attached drawings illustrate the invention.

La figure 1 représente une coupe transversale du dispositif en place sur la tige de direction. Figure 1 shows a cross section of the device in place on the steering rod.

La figure 2 représente le disque d'appui avec les alvéoles et les cannelures de guidage des billes. Figure 2 shows the support disc with the cells and the ball guide grooves.

La figure 3 représente une variante sur laquelle on remplace les billes et leurs alvéoles par des rainures et des nervures perpendiculaires à l'axe longitudinal. FIG. 3 represents a variant in which the balls and their cells are replaced by grooves and ribs perpendicular to the longitudinal axis.

En référence à ces dessins, le dispositif comporte une tige de direction (1) munie d'un disque d'appui (5) qui lui est solidaire et qui recevra dans des alvéoles hémisphériques (8),dont le nombre peut être va- riable, reliées entre elles par une gorge de guidage (9) , des billes(6) dont le nombre sera égal à la moitié de celui des alvéoles. Ces billes seront maintenues au fond des alvéoles par un contre disque (7),usiné de la même façon que le disque d'appui (5), servant de flasque à un manchon (2)contenant un ressort (3)comprimé fortement entre le disque d'appui et le flasque opposé du dit manchon.La compression sur ce flasque sera
répercutée par le contre disque (7) sur les billes ainsi bloquées entre les alvéoles du disque d'appui (5) et celles du contre disque (7).With reference to these drawings, the device comprises a steering rod (1) provided with a support disc (5) which is integral with it and which will receive in hemispherical cells (8), the number of which may be variable. , connected together by a guide groove (9), balls (6), the number of which will be equal to half that of the cells. These balls will be held at the bottom of the cells by a counter disc (7), machined in the same way as the support disc (5), serving as a flange for a sleeve (2) containing a spring (3) compressed strongly between the support disc and the opposite flange of said sleeve. The compression on this flange will be
passed on by the counter disc (7) on the balls thus blocked between the cells of the support disc (5) and those of the counter disc (7).

En position de conduite, le pène d'un antivol de type à blocage de direction n'étant actif, l'ensemble manchon, ressort et billes va tourner librement avec la tige de direction, entrainé par le disque d'appui (5). Lorsque l'antivol de type à blocage de direction sera en position active,le pène de celui-ci sera engagé dans la lumière (4) du manchon empêchant la rotation normale de la tige de direction qui sera contra riée par la pression des billes dans les alvéoles. Sous l'effet d'un couple plus important, les billes vont vaincre la pression du ressort, sortir de leurs alvéoles, suivre la gorge de guidage (9) pour retomber dans les alvéoles suivantes necessîtant un nouvel effort important pour un nouveau déplacement infime des roues, rendant la conduite impossible. In the driving position, the bolt of a steering lock type lock being active, the sleeve, spring and ball assembly will rotate freely with the steering rod, driven by the support disc (5). When the steering lock type lock is in the active position, the bolt of the lock will be engaged in the opening (4) of the sleeve preventing normal rotation of the steering rod which will be constrained by the pressure of the balls in the alveoli. Under the effect of a greater torque, the balls will overcome the pressure of the spring, come out of their cells, follow the guide groove (9) to fall back into the following cells requiring a new significant effort for a new tiny displacement of the wheels, making driving impossible.

Dans la forme de réalisation selon la figure 3, les alvéoles sont rew- placées par des rainures hémicylindriques sur le disque d'appui, et la contrepartie (7) sera usinée de façon à présenter des nervures hémicy lindriques qui prendront place dans les rainures du disque d'appui. In the embodiment according to FIG. 3, the cells are replaced by semicylindrical grooves on the support disc, and the counterpart (7) will be machined so as to present lindric hemicy ribs which will take place in the grooves of the support disc.

Le dispositif selon l'invention est plus particulièrement destiné à l'amélioration des antivols de type à blocage de direction.  The device according to the invention is more particularly intended for improving anti-theft devices of the steering lock type.
