Description

L'invention concerne une roue de sécurité pour véhicule, comprenant une jante comportant un anneau d'assise oblique et un anneau utilisé de façon exceptionnelle en cas d'urgence, disposé sur la base de la jante. The invention relates to a safety wheel for a vehicle, comprising a rim comprising an oblique seat ring and a ring used exceptionally in an emergency, arranged on the base of the rim.

D'après la demande de brevet allemand publiée sous le N" 28 51 187 on connaît un anneau utilisé de façon exceptionnelle en cas d'urgence pour des pneumatiques de véhicules, qui, à l'état monté sur une jante à base plate, forme, en association avec un pneumatique sans chambre, une roue de sécurité pour véhicule. Le pourtour intérieur de l'anneau utilisé de façon exceptionnelle en cas d'urgence est emmanché à force sur la base de la jante. Dans le cas du fonctionnement exceptionnel en cas d'urgence, lorsque, dans le cas d'une fuite d'air, la paroi intérieure du pneumatique s'appuie sur le pourtour extérieur de l'anneau utilisé de façon exceptionnelle en cas d'urgence, il existe le risque que le pneumatique et cet anneau glissent et tournent par rapport à la base de la jante, ce qui conduit à une perte immédiate du couple.Des unités, qui disposent d'une compression latérale réduite, sont particulièrement sensibles à ce phénomène. According to the German patent application published under No. 28 51 187, there is known a ring used exceptionally in an emergency for vehicle tires, which, when mounted on a rim with a flat base, forms , in combination with a tubeless tire, a safety wheel for a vehicle. The inner circumference of the ring used exceptionally in an emergency is force fitted on the base of the rim. In the case of exceptional operation in in an emergency, when, in the event of an air leak, the inner wall of the tire rests on the outer periphery of the ring used exceptionally in an emergency, there is the risk that the pneumatic and this ring slide and rotate relative to the base of the rim, which leads to an immediate loss of torque. Units, which have reduced lateral compression, are particularly sensitive to this phenomenon.

La présente invention a pour but de réaliser la jante et l'anneau utilisé de façon exceptionnelle en cas d'urgence de manière qu'un glissement ou une rotation de l'anneau ne soit pas possible. The present invention aims to achieve the rim and the ring used exceptionally in an emergency so that sliding or rotation of the ring is not possible.

Ce problème est résolu conformément à l'invention grâce au fait que des renfoncements répartis sur la circonférence sont disposés dans la base de la jante et que l'anneau utilisé de façon exceptionnelle en cas d'urgence comporte des parties saillantes correspondantes s'engageant dans les renfoncements et qui forment, avec la jante, une liaison avec blocage en rotation. This problem is solved in accordance with the invention thanks to the fact that recesses distributed on the circumference are arranged in the base of the rim and that the ring used exceptionally in an emergency has corresponding projecting parts engaging in the recesses and which form, with the rim, a connection with rotation lock.

Selon une caractéristique de l'invention, la surface de base des renfoncements est située sur un cercle dont le diamètre correspond, au minimum, au diamètre de centrage pour l'anneau latéral d'assise oblique.  According to a characteristic of the invention, the base surface of the recesses is located on a circle whose diameter corresponds, at least, to the centering diameter for the lateral oblique seat ring.

Selon une autre caractéristique de l'invention, chaque renfoncement comporte, à son autre extrémité, à partir du cercle, dont le diamètre correspond au diamètre de centrage,et dans la direction de l'axe de la roue, une surface limite terminale s'étendant obliquement vers l'extérieur en direction de la base de la jante, l'anneau utilisé de façon exceptionnelle en cas d'urgence étant réalisé de manière à pouvoir être inséré à partir du cercle, dont le diamètre correspond au diamètre de centrage, jusqu'à la surface limite terminale. According to another characteristic of the invention, each recess comprises, at its other end, from the circle, the diameter of which corresponds to the centering diameter, and in the direction of the axis of the wheel, a terminal limit surface s' extending obliquely outwards towards the base of the rim, the ring used exceptionally in an emergency being made so that it can be inserted from the circle, the diameter of which corresponds to the centering diameter, up to 'at the terminal boundary surface.

Selon une autre caractéristique de l'invention, les renfoncements sont réalisés avec des arrondis. According to another characteristic of the invention, the recesses are made with rounded edges.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description donnée ci-après prise en référence aux dessins annexés, sur lesquels
- la figure 1 représente une coupe transversale d'une jante à assise oblique comportant un anneau latéral d'assise oblique vissé et un anneau utilisé de façon exceptionnelle en cas d'urgence et un pneumatique ;
- la figure 2 représente une coupe transversale d'une jante à assise oblique comportant un anneau latéral et un anneau de fermeture ; et
- la figure 3 représente une coupe longitudinale partielle prise suivant la ligne III-III sur la figure 1.Other characteristics and advantages of the present invention will emerge from the description given below taken with reference to the accompanying drawings, in which
- Figure 1 shows a cross section of an oblique seat rim comprising a lateral oblique screwed seat ring and a ring used exceptionally in an emergency and a tire;
- Figure 2 shows a cross section of an oblique seat rim having a side ring and a closure ring; and
- Figure 3 shows a partial longitudinal section taken along line III-III in Figure 1.

La roue de sécurité pour véhicule conforme aux figures 1 et 3 est constituée par une jante à assise oblique 1 comportant un anneau latéral d'assise oblique 2 vissé, un pneumatique sans chambre 3 et un anneau 5 utilisé de façon exceptionnelle en cas d'urgence, disposé dans le pneumatique 3 et sur la base 4 de la jante et qui est constitué de préférence en caoutchouc ou en un autre élastomère. The vehicle safety wheel according to FIGS. 1 and 3 is constituted by an oblique seat rim 1 comprising a lateral oblique seat ring 2 screwed, a tubeless tire 3 and a ring 5 used exceptionally in an emergency. , disposed in the tire 3 and on the base 4 of the rim and which is preferably made of rubber or another elastomer.

La jante 1 comporte , dans la base 4 de la jante, des renfoncements 6 répartis de façon uniforme sur le pourtour et qui possèdent, au niveau des jonctions avec la base 4 de la jante, des rayons 7 de telle sorte que la base de la jante est réalisée approximativement avec une forme ondulée, en coupe transversale. La surface de bas-e 8 des renfoncements 6 se situe au niveau d'un cercle dont le diamètre correspond au diamètre de centrage 9 de l'anneau latéral 2 vissable. A partir de ce cercle dont le diamètre correspond au diamètre de centrage 9, les renfoncements 6 s'étendent, dans la direction de l'axe de la roue, jusqu'à une surface limite extrême 10 s'étendant obliquement vers l'extérieur, auquel cas l'-anneau utilisé de façon exceptionnelle en cas d'urgence peut être inséré par ses parties saillantes 11 jusqu'au niveau de la surface limite terminale 10.Les renfoncements 6 forment, en association avec les parties saillantes Il. de l'anneau 5, un système de blocage en rotation entre la jante et l'anneau. The rim 1 has, in the base 4 of the rim, recesses 6 distributed uniformly around the periphery and which have, at the junctions with the base 4 of the rim, spokes 7 so that the base of the rim is made approximately with a wavy shape, in cross section. The bottom-e surface 8 of the recesses 6 is located at the level of a circle whose diameter corresponds to the centering diameter 9 of the side ring 2 which can be screwed. From this circle, the diameter of which corresponds to the centering diameter 9, the recesses 6 extend, in the direction of the axis of the wheel, to an extreme limit surface 10 extending obliquely outwards, in which case the ring used exceptionally in an emergency can be inserted by its projecting parts 11 up to the level of the terminal limit surface 10.The recesses 6 form, in association with the projecting parts II. of the ring 5, a rotation blocking system between the rim and the ring.

Ceci empêche que, même lorsque le pneumatique 3 est appliqué sur l'anneau 5 utilisé de façon exceptionnelle en cas d'urgence et que la roue du véhicule continue à circuler, le pneumatique et l'anneau 5 ne puissent tourner par rapport à la base de la jante, ce qui empêche l'apparition de frottements et d'endommagements de ces pièces.This prevents that, even when the tire 3 is applied to the ring 5 used in exceptional circumstances in an emergency and the wheel of the vehicle continues to circulate, the tire and the ring 5 cannot rotate relative to the base. of the rim, which prevents the appearance of friction and damage to these parts.

La figure 2 représente une variante de rdalisa- tion d'une jante à assise oblique 1 comportant un anneau late- ral 2 à assise oblique, formé de deux éléments et qui est cons titué à un anneau de verrouillage 2a et un anneau latéral 2b. FIG. 2 shows a variant embodiment of an oblique seat rim 1 comprising a lateral ring 2 with an oblique seat, formed of two elements and which is constituted by a locking ring 2a and a lateral ring 2b.

L'anneau de verrouillage 2a est maintenu au moyen d'une liaison par formes complémentaires à encliquetage brusque dans la jante 1 et est centré conformément à la figure. 1 sur le cercle de centrage de l'anneau,dont le diamètre correspond au diamètre de centrage 9. La réalisation de l'anneau 5 utilisé de façon exceptionnelle en cas d'urgence et de la base 4 de la jante avec les parties saillantes 11 et les renfoncements 6 et la surface de base 8 correspondent à la réalisation décri te en référence la figure 1. The locking ring 2a is held by means of a connection by complementary forms which snap into the rim 1 and is centered in accordance with the figure. 1 on the centering circle of the ring, the diameter of which corresponds to the centering diameter 9. The production of the ring 5 used exceptionally in an emergency and of the base 4 of the rim with the projecting parts 11 and the recesses 6 and the base surface 8 correspond to the embodiment described with reference to FIG. 1.

De façon appropriée on utilise ce système de blocage en rotation dans le cas de bases de jantes moulées, auquel cas les renfoncements sont réalisés lors du procédé de moulage. Les jantes peuvent être également réalisées selon le procédé de laminage ou de forgeage. This rotation blocking system is suitably used in the case of molded rim bases, in which case the recesses are made during the molding process. The rims can also be produced according to the rolling or forging process.

De telles roues de sécurité pour véhicules, cons tituées par un ensemble combiné pneumatique-anneau utilisé de façon exceptionnelle en cas d'urgence-jante,sont utilisées de façon prépondérante dans des véhicules militaires, des véhicules d'incendie et des véhicules de police.  Such vehicle safety wheels, constituted by a combined tire-ring assembly used exceptionally in an emergency-rim, are used predominantly in military vehicles, fire vehicles and police vehicles.
