Abstract
Description
L'objet de l'invention concerne un dispositif de freinage de détresse indépendant pour véhicule automobile. The object of the invention relates to an independent distress braking device for a motor vehicle.
Il est destiné à pratiquer une manoeuvre de sauvetage lorsque les moyens normaux de freinage ne répondent plus afin de provoquer une arrêt immédiat du véhicule lancé. It is intended to perform a rescue maneuver when the normal braking means no longer respond in order to bring about an immediate stop of the launched vehicle.
Il est connu d'utiliser des moyens accessolres même indépendants de freinage consistant en des éléments de blocage de roues lorsque les circuits de freinage d'origine ne fonctionnent plus, mais aucun système ne pouvant donner satisfaction car souvent l'arrêt total est brusque occasionnant des chocs extremement violents presque aussi dangereux qu'une collision ou encore les organes de freinage se rompaient par suite de la force d'inertie décuplée sur le point d'attache toujours insuffisant. It is known to use accessolres, even independent braking means, consisting of wheel locking elements when the original braking circuits no longer function, but no system being able to give satisfaction since often the total stop is abrupt causing extremely violent shocks almost as dangerous as a collision or the braking devices were ruptured due to the tenfold force of inertia at the still insufficient attachment point.
Le dispositif suivant l'invention suppirme ces inconvénients et permet d'obtenir d'abord une progressivité de freinage avant l'arrêt total et ensuite d'assurer une attache indépendante et renforcée par rapport au chassis du véhicule évitant la rupture ou la déformation de la carrosserie. The device according to the invention eliminates these drawbacks and makes it possible first to obtain braking progressiveness before total stopping and then to ensure an independent and reinforced attachment with respect to the chassis of the vehicle avoiding breaking or deformation of the body.
Il est constitué par la combinaison d'abord d'un tapis ou cable déroulable dans le sens de la marche, ensuite d'un éìément amortisseur et enfin d'une monture d'assemblage. It is made up of a combination of a mat or cable that can be rolled out in the direction of travel, then a shock absorbing element and finally an assembly mount.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
Les figures 1 et 2 ainsi que 5, 6 représentent vu en élévation l'élément de freinage.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figures 1 and 2 and 5, 6 show in elevation the braking element.
La figure 3 représente la monture d'assemblage. Figure 3 shows the assembly frame.
La figure 4 est une vue en coupe schématique du dispositif amortisseur. Figure 4 is a schematic sectional view of the damping device.
Sur le chassis d'origine 1 est monté l'armarture d'assemblage 2 avec renfort 3. On the original chassis 1 is mounted the assembly armature 2 with reinforcement 3.
Sur ce renfort est placé l'arbre 4 en acier spécial qui positionne les boîtiers 5, 6 dans lesquels coulissent les galets ou bras de force 8 intégrés au tapis 7.Oet arbre sert d'attache fixe au tapis 7 ou au câble 13. On this reinforcement is placed the shaft 4 of special steel which positions the housings 5, 6 in which the rollers or power arms 8 integrated in the belt slide. This tree serves as a fixed attachment to the carpet 7 or to the cable 13.
Les extrémités débordantes de ces galets sont retenues par une fourche formant palier et dont l'arbre vertical 9 est relié à un amortisseur orienté l0.Oes extrémités coulissent dans les fentes pratiquées sur le boîtier. The projecting ends of these rollers are retained by a fork forming a bearing and whose vertical shaft 9 is connected to a damper oriented l0.Oes ends slide in the slots made on the housing.
Ce galet prend la position 8' en fin de course, c'est à-dire après déroulement du tapis, figure 2. This roller takes the position 8 'at the end of the race, that is to say after the belt has been unwound, FIG. 2.
L'extrêmité du tapis est lestée par une masse métallique 11 qui facilite son déroulement lorsqu'il est déverrouillé par un loquet commandé par un câble de traction relié au tableau de bord. 11 prend la position indiquée sur la figure 2 et bloque la roue 12. The end of the carpet is ballasted with a metal mass 11 which facilitates its unwinding when it is unlocked by a latch controlled by a traction cable connected to the dashboard. 11 takes the position indicated in FIG. 2 and locks the wheel 12.
Le tapis métallique (Fig 1, 2) est préférentiellement remplacé par un câble métallique (Fig 5, 6). Ce câble 13 est lesté par une boule 14 ayant la dimension correspondante à l'intervalle 15 situé entre les roues jumelles 16, 17 (Fig 3). The metal mat (Fig 1, 2) is preferably replaced by a metal cable (Fig 5, 6). This cable 13 is ballasted with a ball 14 having the dimension corresponding to the interval 15 located between the twin wheels 16, 17 (Fig 3).
Le montage du câble est le même que celui du tapis 7 et est relié à l'amortisseur 10 dont la course est limitée par la coulisse 20. The assembly of the cable is the same as that of the belt 7 and is connected to the damper 10, the travel of which is limited by the slide 20.
Lorsque le loquet 19 de retenue est déverrouillé, la boule 14 se coince entre les pneumatiques et le câble s 'enroule sur le moyeu 18. La roue 19 est alors bloquée et les pneumatiques 15, 16 assurent un freinage puissant sans endommager la chaussée. Les carter ou boîtier 5, 6 sont préférentiellement articulés et tourillonnent sur l'arbre 4 afin de constituer un patin de frein qui sous l'effet de l'arrêt du tapis contacte le pneumatique et contribue à l'arrêt du véhicule. When the retaining latch 19 is unlocked, the ball 14 gets stuck between the tires and the cable is wound on the hub 18. The wheel 19 is then blocked and the tires 15, 16 provide powerful braking without damaging the roadway. The casing or housing 5, 6 are preferably articulated and journalled on the shaft 4 so as to constitute a brake shoe which under the effect of the stop of the mat contacts the tire and contributes to the stop of the vehicle.
C'est donc la combinaison tapis ou câble combinée avec le système amortisseur qui caractérise l'invention. It is therefore the carpet or cable combination combined with the damping system which characterizes the invention.
Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d ' ailleurs les matières utilisées pour leur fabrication sans changer pour cela, la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as indeed the materials used for their manufacture without changing the general design of the invention which has just been described.
