Abstract
The invention relates to a device intended to hinder the normal rotation of a steering-wheel in order to prevent the theft of a vehicle. The device is comprised of a disk (5) having hemispheric wells (8) which are connected by a guiding groove (9) integral with the steering rod (1), a compressed spring (3) bearing onto the disk, the pressure of the spring being exerted on the end-plate of a sleeve (2) which transmits the pressure through a counter-disk (7) comprising the same wells as the disk (5) to balls (6) whose number is half of that of the wells. When the bolt of an anti-theft device of the steering wheel locking type is engaged into the port (4) of the sleeve (2) and when a normal torque is applied to the steering-wheel, the balls prevent the rotation of the bearing disk (5) and, consequently, of the steering rod with which it it integral. When applying a higher torque, the balls will overcome the pressure of the spring, will get out of their wells, run into the guiding grooves and fall into the following wells, thereby implying a new important effort for a minimum displacement of the wheels, thereby making the driving of the car impossible.
Description
Dispositif antivol à rotation contrariée pour véhicules automobilesControlled rotation anti-theft device for motor vehicles
La présente invention a trait d'une manière générale à des dispo - sitifs en vue de limiter la rotation d'un arbre, et plus particu¬ lièrement à des dispositifs destinés à rendre impossible la con - duite d'un véhicule automobile, en interdisant la rotation norma - le du volant qui commande l'orientation des roues, lorsque l'anti¬ vol est en position active.The present invention relates generally to devices - for the purpose of limiting the rotation of a shaft, and more particularly to devices intended to make driving of a motor vehicle impossible, by prohibiting normal rotation - the steering wheel which controls the orientation of the wheels, when the anti-theft is in the active position.
Des dispositifs de ce type général existent selon de nombreuses réalisations et sont utilisés pour empêcher l'orientation des roues. Une caractéristique commune à la plupart des dispositifs antivol connus, agissant sur la direction, est qu'ils assurent le blocage définitif de la tige de direction, cette disposition pré¬ sente certains avantages, mais est également désaventageuse selon au moins un aspect, ceci parcequ'un couple violent appliqué sur le volant peut provoquer la rupture des fixations de l'antivol, ren - dant celui-ci inopérant et permettant à nouveau aux roues de s'o - rienter normalement.Devices of this general type exist according to many embodiments and are used to prevent the orientation of the wheels. A characteristic common to most known anti-theft devices, acting on the steering, is that they ensure the final blocking of the steering rod, this arrangement has certain advantages, but is also disadvantageous in at least one aspect, this because 'A violent torque applied to the steering wheel can cause the fasteners of the lock to break, making it inoperative and allowing the wheels to orient themselves normally.
Dans le dispositif antivol selon l'invention, disposition est pri¬ se pour contrarier la rotation de la tige de direction sans qu'un effort violent puisse provoquer la rupture de quelque élément que ce soit.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.
Il comporte selon une première caractéristique, une tige de direc¬ tion sur laquelle est fixé un disque qui sert d'appui à un ressort puissant, lequel exerce sa pression sur le rebord d'un manchon lui-même appuyé au disque par le rebord usiné de son extrémité op- posée, à travers trois billes fortement appliquées dans des alvé - oies.According to a first characteristic, it has a directing rod on which is fixed a disc which serves as a support for a powerful spring, which exerts its pressure on the rim of a sleeve itself supported on the disc by the machined rim from its opposite end, through three balls strongly applied in alveoli - geese.
Le pêne d'un antivol de type à blocage de direction vient se posi¬ tionner dans une lumière du manchon qu'il immobilise, empêchant ainsi la rotation de la tige de direction et l'orientation des roues, lorsqu'un couple normal est appliqué sur le volant.The bolt of a steering lock type lock comes to position in a lumen of the sleeve which it immobilizes, thus preventing the rotation of the steering rod and the orientation of the wheels, when a normal torque is applied. on the steering wheel.
Sous l'effet d'un couple plus important, déterminé par le ressort, les billes vont se dégager de leurs alvéoles qu'elles vont fran - chir comme autant de cames, pour retomber dans les alvéoles sui - vantes qui contrarient la rotation, rendant la conduite du véhicu- le équipé impossible.Under the effect of a greater torque, determined by the spring, the balls will disengage from their cells which they will pass through as many cams, to fall back into the following cells which counteract rotation, making driving the equipped vehicle impossible.
Selon un mode particulier de réalisation, les billes peuvent être remplacées par des nervures et les logements dez billes par des rainures.According to a particular embodiment, the balls can be replaced by ribs and the housings of the balls by grooves.
Les dessins annexés illustrent l'invention.
— La figure I représente une coupe transversale du dispositif en place sur la tige de direction.The accompanying drawings illustrate the invention. - Figure I shows a cross section of the device in place on the steering rod.

En référence à ces dessins, le dispositif comporte une tige de direction (l) munie d'un disque d'appui (5) qui lui est solidaire et qui recevra dans des alvéoles hémisphériques (8) dont le nombre peut être variable, 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)» ser¬ vant de flasque à un manchon (2) contenant un ressort (3) compri¬ mé 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 (l) 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 between them 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 backing disc (7) machined in the same way as the support disc (5) "serving as a flange with a sleeve (2) containing a spring (3) strongly compressed 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 pêne d'un antivol de type à blocage de direction n'étant pas actif, l'ensemble manchon, ressort et billes va tourner librement avec la tige de direction, entrainé par le disque d'appui ( )» Lorsque 1 *antivol de type à blocage de di - rectionsera en position active, le pêne de celui-ci sera engagé dans la lumière (4) du manchon, empêchant la rotation normale de la tige de direction qui sera contrariée 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 sui¬ vantes, nécessitant un nouvel effort important pour un nouveau dé¬ placement infime des roues, rendant la conduite impossible. Dans la forme de réalisation selon la figure 3 les alvéoles sont remplacées par des nervures hémicylindriques sur le disque d'appui, et la contre partie (7) sera usinée de façon à présenter des ner - vures hémicylindriques qui prendront place dans les rainures du disque d'appui.In the driving position, the bolt of a steering lock type lock not being active, the sleeve, spring and ball assembly will rotate freely with the steering rod, driven by the support disc () ” When the steering lock type anti-theft device is in the active position, the bolt of the latter will be engaged in the opening (4) of the sleeve, preventing normal rotation of the steering rod which will be thwarted by the pressure of the balls. in the alveoli. Under the effect of a higher torque, the balls will overcome the pressure of the spring, exit their cells follow the guide groove (9) to fall back into the following cells, requiring a new significant effort for a new die ¬ tiny placement of the wheels, making driving impossible. In the embodiment according to FIG. 3, the cells are replaced by semi-cylindrical ribs on the support disc, and the counterpart (7) will be machined so as to present semi-cylindrical ribs which will take place in the grooves of the disc. support.
