Abstract
Description
La présente invention a pour objet une centrale hy
draulique intégrée, c'est-à-dire un dispositif compact qui com
porte, en un ensemble unitaire, à la fois un moteur électrique,
une pompe hydraulique et un réservoir hydraulique, lequel peut
être de dimensions variables.The present invention relates to a central hy
integrated hydraulics, i.e. a compact device that com
carries, in a unitary assembly, both an electric motor,
a hydraulic pump and a hydraulic tank, which can
be of variable dimensions.
Cet ensemble unitaire est constitué par : un moteur
électrique; une pompe hydraulique dont l'arbre d'entraînement
est constitué par l'arbre dudit moteur électrique; un réservoir
cylindrique, d'un diamètre pratiquement égal à celui du moteur
électrique et placé en bout de celui-ci du côté où se trouve la
pompe, de sorte que celle ci se trouve à l'intérieur dudit ré
servoir, ce réservoir étant constitué par un tube serré entre deux flasques, l'un étant le flasque du moteur électrique qui porte le palier commun au moteur et à la pompe, l'autre étant un flasque mobile serré par un écrou vissé sur la tubulure de
sortie de la pompe qui est disposée de façon pratiquement co-axiale au tube.This unitary unit is made up of: a motor
electric; a hydraulic pump whose drive shaft
consists of the shaft of said electric motor; a reservoir
cylindrical, of a diameter practically equal to that of the motor
electric and placed at the end of it on the side where the
pump, so that it is inside said re
servoir, this tank being constituted by a tube clamped between two flanges, one being the flange of the electric motor which carries the bearing common to the motor and to the pump, the other being a movable flange tightened by a nut screwed on the tubing of
outlet of the pump which is arranged practically coaxially with the tube.
Le tube et la tubulure de sortie de la pompe peuvent
etre de dimensions variables, ce qui permet donc de faire varier à volonté la capacité du réservoir.The pump outlet tube and tubing can
be of variable dimensions, which therefore makes it possible to vary the capacity of the tank at will.
A titre d'exemple non limitatif et pour faciliter la
compréhension de l'invention, on a représenté aux dessins annexes:
Figure 1, une vue en élévation latérale en coupe lon-
gitudinale d'un mode de réalisation de l'invention.By way of nonlimiting example and to facilitate the
understanding of the invention, the accompanying drawings show:
Figure 1, a side elevational view in section along
gitudinal of an embodiment of the invention.
Figure 2, une vue partielle illustrant une variante de la figure 1. Figure 2, a partial view illustrating a variant of Figure 1.
En se reportant à ces figures, on voit que l'ensemble
unitaire est constitué par un moteur électrique 1, dont un des
flasques 3 porte un boîtier 4, dans lequel-est placé un roulement 5, capable de supporter des charges composites : charges radia
les venant en majorité de l'arbre 2 du moteur 1 et charge axiale
venant d'une pompe hydraulique montée en bout de l'arbre 2.Referring to these figures, we see that the whole
unit consists of an electric motor 1, one of which
flanges 3 carries a housing 4, in which a bearing 5 is placed, capable of supporting composite loads: radia loads
coming mainly from the shaft 2 of the motor 1 and axial load
from a hydraulic pump mounted at the end of the shaft 2.
Comme on le voit sur la figure, l'arbre 2 de la pompe se prolonge -au-delà du moteur 1, pour aller jusqu'au plateau biais 6 de la
pompe hydraulique dont le carter 7 ne fait qu'une seule pièce
avec le boîtier 4. Le plateau biais 6 anime les pistons 8. Le
carter 7 comporte une ouverture 9 pour l'admission du liquide
hydraulique dans la pompe, l'orifice de sortie de la pompe étant muni d'une tubulure 10, parallèle à l'arbre 2.As can be seen in the figure, the shaft 2 of the pump extends beyond the motor 1, to go to the bias plate 6 of the
hydraulic pump of which the casing 7 is one piece
with the housing 4. The bias plate 6 drives the pistons 8. The
casing 7 has an opening 9 for admitting the liquid
hydraulic in the pump, the outlet of the pump being provided with a pipe 10, parallel to the shaft 2.
On voit ainsi que le roulement de palier 5 est commun au moteur et à la pompe. It can thus be seen that the bearing 5 is common to the motor and to the pump.
Le flasque 3 d'extrémité du moteur 1 comporte, en outre, un rebord circulaire 12 formant une sorte de cuvette, ce rebord étant muni d'une nervure 11. Sur le rebord 12 est em boîté un tube 13. A l'autre extrémité, ledit tube 13 est emboité sur un flasque 14, comportant un rebord 15, identique au rebord 12 du flasque 3, ce rebord 15 comportant une nervure 16, identique à la nervure 11. En son centre, le flasque 14 comprend un orifice 17, qui est traversé par l'extrémité filetée 19 du tube 10; un écrou 18 se vissant sur cette extrémité 19 permet de serrer le tube 13 entre le flasque 3 et le flasque 14; de sorte quelle tube 13 et ces deux flasques définissent un volume clos qui constitue un réservoir hydraulique à l'intérieur duquel se trouve la pompe hydraulique. De préférence, on dispose un joint d'étanchéité 20 dans l'orifice 17, un distributeur 21 au bout du tube 10 et un bouchon 22 sur le flasque 14, pour le remplissage du réservoir. The end plate 3 of the motor 1 further comprises a circular rim 12 forming a sort of bowl, this rim being provided with a rib 11. On the rim 12 is fitted a tube 13. At the other end , said tube 13 is fitted onto a flange 14, comprising a flange 15, identical to the flange 12 of the flange 3, this flange 15 comprising a rib 16, identical to the rib 11. In its center, the flange 14 comprises an orifice 17, which is crossed by the threaded end 19 of the tube 10; a nut 18 screwing onto this end 19 makes it possible to tighten the tube 13 between the flange 3 and the flange 14; so which tube 13 and these two flanges define a closed volume which constitutes a hydraulic tank inside which the hydraulic pump is located. Preferably, there is a seal 20 in the orifice 17, a distributor 21 at the end of the tube 10 and a plug 22 on the flange 14, for filling the reservoir.
Il est bien évident que l'on peut choisir à volonté la longueur du tube 13 et du-tube 10 et déterminer ainsi la longueur du réservoir. It is obvious that one can choose at will the length of the tube 13 and of the tube 10 and thus determine the length of the tank.
La figure 2 illustre une variante selon laquelle le réservoir est constitué par un boîtier 23, de section indifférente, comportant à une de ses extrémités un rebord 24 s'adaptant contre la nervure 11 et à son autre extrémité, une paroi 25, remplaçant le flasque 14. FIG. 2 illustrates a variant according to which the reservoir is constituted by a housing 23, of indifferent section, comprising at one of its ends a flange 24 fitting against the rib 11 and at its other end, a wall 25, replacing the flange 14.
