Abstract
Description
L'invention concerne un dispositif pour monter un arbre de sortie dans un carter d'engrenage différentiel dans un véhicule automobile dans lequel on dispose un corps de palier entre le carter de la transmission et l'arbre de sortie. The invention relates to a device for mounting an output shaft in a differential gear housing in a motor vehicle in which there is a bearing body between the transmission housing and the output shaft.
On connaît par le document DE-U 93 12 507 un agencement de montage pour un arbre de sortie de transmission passé dans un carter d'engrenage différentiel. Document DE-U 93 12 507 discloses a mounting arrangement for a transmission output shaft passed through a differential gear case.
Dans le cas de ce dispositif on prévoit, pour réduire les vibrations des arbres et les bruits qui en découlent, de disposer dans une rainure annulaire de 1 'arbre de sortie un ressort semi-circulaire à spires parallèles, qui d'une part s'appuie contre le fond de la rainure annulaire et d'autre part contre le carter de l'engrenage différentiel. Ce ressort semi-circulaire à spires parallèles s'étend sur un angle d'enroulement de plus de 1800, de préférence toutefois de plus de 2100. Avec ce dispositif on peut avantageusement intercepter les vibrations radiales de l'arbre de sortie, alors que du fait des tolérances de fabrication, des vibrations axiales se produisant dans 1 'ensemble de l'agencement peuvent continuer à survenir.In the case of this device, to reduce the vibrations of the trees and the noises which result therefrom, provision is made to place in a annular groove of the output shaft a semi-circular spring with parallel turns, which on the one hand is presses against the bottom of the annular groove and on the other hand against the housing of the differential gear. This semi-circular spring with parallel turns extends over a winding angle of more than 1800, preferably however more than 2100. With this device it is advantageous to intercept the radial vibrations of the output shaft, while Within manufacturing tolerances, axial vibrations occurring throughout the arrangement can continue to occur.
L'invention a en conséquence pour objet de proposer pour des arbres de sortie de ce type un agencement de palier, avec lequel on puisse éviter de façon efficace d'avoir aussi bien des vibrations axiales que des vibrations radiales de l'arbre de sortie. The object of the invention is therefore to propose for output shafts of this type a bearing arrangement, with which it is possible to effectively avoid having both axial and radial vibrations of the output shaft.
A cet effet l'invention concerne un agencement de palier dans lequel on dispose, entre le corps de palier et l'arbre de sortie, une bague de centrage disposée coaxialement par rapport à l'arbre de sortie et précontrainte au moyen d'un ressort contre le corps de palier. De cette façon l'arbre de sortie est monté sans jeu axialement et radialement. Les bruits de vibration gênants déclenchés par l'arbre de sortie qui vibre - sont de cette façon supprimés. To this end, the invention relates to a bearing arrangement in which there is, between the bearing body and the output shaft, a centering ring disposed coaxially with the output shaft and preloaded by means of a spring. against the bearing housing. In this way the output shaft is mounted axially and radially without play. The annoying vibration sounds triggered by the vibrating output shaft - are thereby suppressed.
Suivant d'autres caractéristiques de l'invention
- le ressort entoure de façon coaxiale l'arbre de sortie et s'appuie du côté de la transmission sur un collet d'arbre,
- la bague de centrage présente une fente axiale, qui s'étend sur toute sa longueur,
- on dispose dans la bague de centrage des rainures,
- la bague de centrage présente dans la zone de la surface d'appui pour le ressort le long d'une partie de son étendue longitudinale une surface annulaire extérieure conique,
- le corps de palier présente sur sa face intérieure une surface intérieure conique, qui repose avec un écart angulaire sur la surface conique de la bague de centrage
On va expliquer ci-après l'invention à partir d'un exemple de réalisation, qui est représenté sur les dessins annexés, sur lesquels;;
La figure 1 montre une coupe schématique transversale de l'arbre et de la bride d'articulation dans la zone de l'agencement de palier.According to other features of the invention
- the spring coaxially surrounds the output shaft and rests on the side of the transmission on a shaft collar,
the centering ring has an axial slot, which extends over its entire length,
- there are grooves in the centering ring,
- the centering ring present in the area of the bearing surface for the spring along part of its longitudinal extent an outer conical annular surface,
- the bearing housing has on its inner face a conical inner surface, which rests with an angular distance on the conical surface of the centering ring
We will explain below the invention from an embodiment, which is shown in the accompanying drawings, in which ;;
Figure 1 shows a schematic cross section of the shaft and the hinge flange in the area of the bearing arrangement.
La figure 2 montre une vue de dessus de la bague de centrage fendue, et
La figure 3 montre une coupe transversale à travers la bague de centrage selon la figure 2.FIG. 2 shows a top view of the split centering ring, and
Figure 3 shows a cross section through the centering ring according to Figure 2.
Sur la figure 1 on a désigné par la référence numérique l 1 'arbre de sortie d'un engrenage différentiel, non représenté, qui est relié du côté de l'entraînement par une bride d'articulation 2. Le montage radial de l'arbre de sortie 1 est réalisé dans le carter zen de l'engrenage différentiel 3 au moyen d'un palier 6, qui est de préférence constitué sous la forme d'un roulement rainuré à billes.Le roulement 6 s'appuie axialement au moyen d'une bague de sécurité 8 contre le carter de transmission 3. I1 ne repose pas toutefois directement sur l'arbre de sortie 1, mais il s'appuie radialement vers l'intérieur sur une bague de centrage 9, qui repose par sa face intérieure sur l'arbre de sortie 1 et est précontrainte au moyen d'un ressort 10 de façon coaxiale par rapport à l'arbre de sortie. Ce ressort 10 repose de son côté sur un collet 11 de l'arbre de sortie, du côté de la transmission. L'agencement de palier tout entier est finalement rendu étanche d'une manière connue au moyen d'une bague d'étanchéité 7 s'appuyant contre la bride d'articulation 2 et par rapport à l'environnement. In Figure 1 is designated by the reference numeral 1 1 the output shaft of a differential gear, not shown, which is connected on the side of the drive by a hinge flange 2. The radial mounting of the shaft output 1 is produced in the zen casing of the differential gear 3 by means of a bearing 6, which is preferably constituted in the form of a grooved ball bearing. The bearing 6 is supported axially by means of a safety ring 8 against the transmission casing 3. I1 does not, however, rest directly on the output shaft 1, but rests radially inward on a centering ring 9, which rests on its inner face on the output shaft 1 and is prestressed by means of a spring 10 coaxially with the output shaft. This spring 10 rests on its side on a collar 11 of the output shaft, on the side of the transmission. The entire bearing arrangement is finally sealed in a known manner by means of a sealing ring 7 pressing against the articulation flange 2 and relative to the environment.
La bague de centrage 9 représentée à la figure 2 présente le long de toute son étendue longitudinale une fente 5, qui assure avec des rainures longitudinales 12 à 14, à usiner de préférence dans la bague de centrage, une possibilité de déformation radiale relativement légère. The centering ring 9 shown in Figure 2 has along its entire longitudinal extent a slot 5, which provides with longitudinal grooves 12 to 14, preferably to be machined in the centering ring, a possibility of relatively slight radial deformation.
Sur la figure 3 on a représenté la bague de centrage 9 selon une représentation en coupe transversale, sur laquelle on peut voir que celle-ci est constituée en forme de cône en direction de la surface d'appui 16 pour l'élément élastique 10. Cette configuration en forme de cône de la bague de centrage 8 rend possible sa précontrainte entre l'arbre 1 et le corps de palier 6, ce dernier présentant sur sa face intérieure également une surface intérieure conique 19, sur laquelle repose avec un écart angulaire la surface extérieure conique 15 de la bague de centrage 9. FIG. 3 shows the centering ring 9 in a cross-sectional representation, on which it can be seen that it is formed in the form of a cone in the direction of the bearing surface 16 for the elastic element 10. This cone-shaped configuration of the centering ring 8 makes it possible to prestress it between the shaft 1 and the bearing body 6, the latter having on its inner face also a conical inner surface 19, on which rests with an angular distance the conical outer surface 15 of the centering ring 9.
