Abstract
Description
Elle se rapporte à une transmission pour véhicule automobile comportant un groupe moto-propulseur situé à l'avant et relié aux roues arrière motrices par un arbre de transmission longitudinal placé dans un tube de poussée solidaire d'un pont arrière rigide. It relates to a transmission for a motor vehicle comprising a power train located at the front and connected to the rear driving wheels by a longitudinal drive shaft placed in a thrust tube secured to a rigid rear axle.
Dans des transmissions de ce type,la poussée longitudinale provenant du pont arrière est transmise à la structure avant par une cale élastique qui sert en même temps de cale de suspension arrière pour le groupe moto-propulseur. Cette disposition ne permet pas d'utiliser une cale suffisamment souple pour assurer une bonne filtration des vibrations du moteur, ce qui est préjudiciable à l'obtention d'un bon confort. In transmissions of this type, the longitudinal thrust coming from the rear axle is transmitted to the front structure by an elastic block which at the same time serves as rear suspension block for the powertrain. This arrangement does not allow the use of a sufficiently flexible shim to ensure good filtration of the vibrations of the engine, which is detrimental to obtaining good comfort.
L'invention a pour but de remédier à cet inconvénient. The invention aims to remedy this drawback.
Elle s'applique donc à une transmission pour véhicule automobile, comprenant un groupe moto-propulseur situé à l'avant et un pont arrière rigide solidaire d'un tube de poussée dont la partie avant prend appui sur la caisse par l'intermédiaire d'une cale élastique, un arbre de transmission longitudinal, disposé dans le tube de poussée, étant relié à l'arbre de sortie du groupe motopropulseur par un joint universel. It therefore applies to a transmission for a motor vehicle, comprising a powertrain located at the front and a rigid rear axle secured to a thrust tube, the front part of which bears on the body via an elastic block, a longitudinal transmission shaft, disposed in the thrust tube, being connected to the output shaft of the powertrain by a universal joint.
Elle est caractérisée en ce que la partie arrière du groupe moto-propulseur est suspendue sur la caisse au moyen d'un support élastique distinct et plus souple que la cale supportant la poussée longitudinale, des moyens étant prévus entre l'arbre de sortie du groupe moto-propulseur et ledit joint universel pour autoriser les débattements angulaires dus à la souplesse du support élastique. It is characterized in that the rear part of the powertrain is suspended on the body by means of a separate elastic support which is more flexible than the block supporting the longitudinal thrust, means being provided between the output shaft of the group. motor-propellant and said universal joint to allow angular deflections due to the flexibility of the elastic support.
Ces moyens peuvent être constitués par un accouple rnent élastique ou un joint universel tel qu'un joint de cardan. These means can be constituted by an elastic coupling or a universal joint such as a universal joint.
Suivant d'autres caractéristiques
- lesdits moyens sont reliés à un arbre intermédiaire monté coulissant par rapport à un arbre relié audit joint universel;
- l'arbre de sortie de la bofte de vitesses porte un arbre tubulaire relié auxdits moyens et l'arbre intermédiaire porte un prolongement assurant son centrage dans l'arbre tubulaire au moyen d'un manchon élastique ou de tout autre moyen équivalent.According to other characteristics
- Said means are connected to an intermediate shaft slidably mounted relative to a shaft connected to said universal joint;
- The output shaft of the gearbox carries a tubular shaft connected to said means and the intermediate shaft carries an extension ensuring its centering in the tubular shaft by means of an elastic sleeve or any other equivalent means.
Un exemple de réalisation de l'invention fait l'objet de la description qui suit, en référence au dessin joint dont la Figure unique représente une coupe longitudinale partielle de la transmission aménagée selon l'invention. An exemplary embodiment of the invention is the subject of the description which follows, with reference to the accompanying drawing, the single figure of which represents a partial longitudinal section of the transmission fitted out according to the invention.
On voit sur la partie gauche de la Figure,l'extrémité d'une botte de vitesses 1 qui fait partie d'un groupe moto-propulseur situé à l'avant d'un véhicule automobile. Cette bofte de vitesses est fixée, par des boulons 2, sur une platine 3 qui est reliée à la caisse 4 par l'intermédiaire d'un support élastique souple 5. We see on the left side of the Figure, the end of a gear boot 1 which is part of a power train located at the front of a motor vehicle. This gearbox is fixed, by bolts 2, to a plate 3 which is connected to the body 4 by means of a flexible elastic support 5.
De la boîte de vitesses 1 sort un arbre 6 sur lequel est monté un arbre tubulaire 7,au moyen de cannelures 8, la solidarisation étant assurée par une vis 9 et une rondelle 10. From the gearbox 1 comes out a shaft 6 on which is mounted a tubular shaft 7, by means of grooves 8, the connection being ensured by a screw 9 and a washer 10.
Sur l'arbre tubulaire 7 est soudé un premier plateau 11 d'un accouplement élastique dont un second plateau 13 est solidaire d'un arbre intermédiaire 14. De préférence, ce dernier porte un prolongement 15 assurant son centrage dans l'arbre tubulaire 7 au moyen d'un manchon élastique 16 ou de tout autre moyen équivalent. On the tubular shaft 7 is welded a first plate 11 of an elastic coupling, a second plate 13 of which is secured to an intermediate shaft 14. Preferably, the latter carries an extension 15 ensuring its centering in the tubular shaft 7 at by means of an elastic sleeve 16 or any other equivalent means.
Sur l'arbre 14 est monté un arbre tubulaire 17, ces deux arbres étant solidaires en rotation, mais pouvant coulisser l'un par rapport à l'autre, grâce à des cannelures 18. On the shaft 14 is mounted a tubular shaft 17, these two shafts being integral in rotation, but being able to slide relative to one another, by means of grooves 18.
L'arbre tubulaire 17 est relié par un joint universel 19, tel qu'un joint de cardan, à un arbre de transmission longitudinal 20 qui aboutit à un différentiel, non représenté.L'arbre 20 est porté par des roulements tels que 21 dans un tube de poussée 22 solidaire, ainsi qu'il est connu, d'un pont arrière rigide, non représenté, constitué par un carter contenant le différentiel et des arbres de roues transversaux. The tubular shaft 17 is connected by a universal joint 19, such as a universal joint, to a longitudinal drive shaft 20 which leads to a differential, not shown. The shaft 20 is carried by bearings such as 21 in a push tube 22 secured, as is known, to a rigid rear axle, not shown, constituted by a casing containing the differential and transverse wheel shafts.
Une plaque 23 est serrée entre l'extrémité avant du tube de poussée 22 et une pièce 24, en forme de tulipe, au moyen de vis 25. Cette pièce 24 assure, en même temps, le blocage de la bague extérieure du roulement 21 dans le tube 22. A plate 23 is clamped between the front end of the push tube 22 and a part 24, in the form of a tulip, by means of screws 25. This part 24 ensures, at the same time, the blocking of the outer ring of the bearing 21 in the tube 22.
Une cale en élastomère 26 est adhérisée sur la plaque 23 ainsi que sur une armature 27,cette dernière étant solidarisée de la caisse 4 par des vis telles que 28. An elastomer wedge 26 is adhered to the plate 23 as well as to a frame 27, the latter being secured to the body 4 by screws such as 28.
La cale en élastomère 26 comporte, au delà de l'armature 27,un talon 29 sur lequel peut éventuellement porter un épaulement 30 de la pièce 24. The elastomer wedge 26 comprises, beyond the frame 27, a heel 29 on which can optionally bear a shoulder 30 of the part 24.
Un ressort hélicoïdal 31,disposé entre l'arbre 14 et le joint universel 19 assure une mise en contrainte longitudinale de la transmission. A helical spring 31, disposed between the shaft 14 and the universal joint 19 provides longitudinal stressing of the transmission.
Dans la transmission qui vient d'être décrite, la poussée du pont arrière, transmise par le tube 22, est appliquée à la caisse 4 par la cale élastique 26, située sensiblement au droit du joint universel 19. Cette cale 26 et le joint universel 19 permettent, de façon habituelle, les légers débattements angulaires du tube de poussée 22. In the transmission which has just been described, the thrust from the rear axle, transmitted by the tube 22, is applied to the body 4 by the elastic shim 26, located substantially in line with the universal joint 19. This shim 26 and the universal joint 19 usually allow slight angular deflections of the push tube 22.
En outre,le support 5 ayant une grande souplesse (il peut en effet être par exemple cinq fois moins raide que la cale unique antérieure) assure une bonne filtration des vibrations du moteur ce qui améliore considérablement le confort. Les légers débattements angulaires dans la transmission, causés par la souplesse du support 5, sont alors encaissés par l'accouplement élastique 12. In addition, the support 5 having great flexibility (it can in fact be for example five times less stiff than the single previous wedge) ensures good filtration of the vibrations of the motor which considerably improves comfort. The slight angular deflections in the transmission, caused by the flexibility of the support 5, are then collected by the elastic coupling 12.
