Abstract

The steering rack for a motor vehicle has a section forming the rack and two end sections forming end shafts. One end of the rack section (6) is connected to the respective end shaft by a tube (10) with its ends welded around waisted projections, at one end on the outer end of the rack, and at the other end on the inner end of the inner shaft. Both ends of the rack section can be connected to the end shafts via tubes. The outer diameters of the rack section, tube, and end shafts are equal.

Description

Les crémaillères de direction pour véhicules automo biles sont constituées par une barre en acier appropri, dans une partie adéquate de laquelle est taillée une crémaillère, et dont les deux extrémités scnt usinés pour constituer des embouts d'assemblage a d'autres pièces de commande de la direction. Steering racks for motor vehicles consist of a suitable steel bar, in a suitable part of which is cut a rack, and the two ends of which are machined to form end fittings for other control parts of The direction.

Il s'agit donc d'un organe massif, relativement lourd; or on cherche actuellement à alléger dans toute la mesure du possible les véhicules, en vue d'obtenir des économies d'energie lors de leur utilisation
A cet effet, la présente invention a pour objet une crémaillère de direction pour vf-hicules automobiles dont la partie formant crXmailldre et les deux extrémités formant embout sont taillées ou usinées comme précédemment dans une barre en acier mais, au lieu d'etre venue d'une pièce avec les embouts, une des extrémités au moins de sa partie formant crémaillère est reliée à l'embout correspondant par un tube dont les extrémités sont soudées en bot et serties, d'un cté a ladite extrémité de la partie formant crémailldre et de l'autre côté a l'extremité intérieure de l'embout correspondant.It is therefore a massive, relatively heavy organ; However, we are currently seeking to lighten vehicles as much as possible, in order to obtain energy savings during their use.
To this end, the subject of the present invention is a steering rack for motor vehicles, the part forming crXmailldre and the two ends forming end pieces are cut or machined as before in a steel bar but, instead of having come from '' a part with the end caps, at least one of the ends of its rack-forming part is connected to the corresponding end-piece by a tube whose ends are bot-welded and crimped, with one side at said end of the part forming the rack and on the other side at the inner end of the corresponding nozzle.

Le gain de poids ainsi obtenu peut etre de l'ordre des 2/5 sans que la fiabilité soit le moins du monde diminuée. The weight gain thus obtained can be of the order of 2/5 without the reliability being in the least diminished.

Le dessin annexé montre a titre d'exemple un mode de réalisation de la présente invention. The accompanying drawing shows by way of example an embodiment of the present invention.

La figure 1 est une vue en coupe d'une crémaillère de direction de type classique. Figure 1 is a sectional view of a conventional type steering rack.

La figure 2 est une vue analogue mais à plus grande échelle, avec arrachements,de la même crémaillère de direction réalisée suivant la présente invention.  Figure 2 is a similar view but on a larger scale, with parts broken away, of the same steering rack produced according to the present invention.

La figure 3 est une vue en coupe faite suivant la
ligne III-III de la figure 2.Figure 3 is a sectional view taken along the
line III-III of Figure 2.

La crémaillère de direction 1 montrée à la figure 1
comporte une partie 2 formant crémaillère, taillée a llempla-
cement adéquat, et deux extrémités 3 et 4 usinées, constituant
des embouts ; elle est réalisée en une seule pièce dans une
barre cylindrique en acier.The steering rack 1 shown in Figure 1
has a part 2 forming a rack, cut to size
adequate cement, and two ends 3 and 4 machined, constituting
end caps; it is made in one piece in one
cylindrical steel bar.

La meme crémaillère de direction 5, réalisée suivant
la présente invention et montrée a la figure 2, comporte
également une partie'6 formant crémaillère, taillée dans un
tronçon 7 d'une barre en acier cylindrique, dont une extrémité,
immédiatement adjacente a cette partie 6 formant crémaillère,
constitue le même embout 8 que celui 3 de la crémaillère de
direction 1 montrée à la figure 1.The same steering rack 5, made according to
the present invention and shown in Figure 2, comprises
also part'6 forming a rack, cut in a
section 7 of a cylindrical steel bar, one end of which,
immediately adjacent to this part 6 forming a rack,
constitutes the same end piece 8 as that 3 of the rack
direction 1 shown in figure 1.

Par contre l'embout 9, analogue à celui 4 montré å
la figure 1,n'est pas venu-d'une pièce avec cette partie 6
formant crémaillère de la barre 7, mais relie a celle-ci par
un tronçon 10 de tube dont les extrémités sont engagées sur
les extrémités correspondantes du tronçon 7 de barre formant
crémaillère 6 et de l'embout 9 qui, cet effet, ont été
usinées de façon a être de moindre diamètre, et à comporter
des gorges diamétrales 11 et 12 ; ce tronçon tubulaire 10 est -fixO auxdites extrémités par des soudures annulaires 13-et 14
et des sertissages 15 et 16 dans ces gorges 11 et 12. By cons tip 9, similar to that shown 4 å
Figure 1, did not come from one room with this part 6
forming a rack of the bar 7, but connected to the latter by
a section 10 of tube whose ends are engaged on
the corresponding ends of the bar section 7 forming
rack 6 and end piece 9 which, for this purpose, have been
machined to be of smaller diameter, and to include
diametrical grooves 11 and 12; this tubular section 10 is -fixO at said ends by annular welds 13-and 14
and crimps 15 and 16 in these grooves 11 and 12.

I1 est-bien évident que si l'embout 8 n'était pas
situé au voisinage'immédiat d'une extrémité'de la partie 6
de barre cylindrique 7 formant la crémaillère, il sevrait relié
a l'extrémité correspondante de cette partie6'debarre
cylindriqueparun tronçon tubulaire comme celui 10 reliant
son autre extrémité l'embout 9. It is obvious that if the end piece 8 was not
located near 'one end' of part 6
of cylindrical bar 7 forming the rack, it was connected
at the corresponding end of this section
cylindrical by a tubular section like that connecting 10
its other end the nozzle 9.
