CARTER CONTENANT UN MÉCANISME, EN PARTICULIER D'UNE BOÎTE DE VITESSES DE VÉHICULE AUTOMOBILE
La présente invention concerne un carter contenant un mécanisme, en particulier d'une boîte de vitesses de véhicule automobile. CRANKCASE CONTAINING A MECHANISM, PARTICULARLY A MOTOR VEHICLE GEARBOX
The present invention relates to a housing containing a mechanism, in particular of a motor vehicle gearbox.
Dans un carter de boîte de vitesses, l'huile qui se trouve dans le fond de ce carter a tendance à se déplacer, classiquement, en remontant le long de la paroi de ce dernier lorsque le véhicule accélère, freine ou prend un virage. Le sens et l'amplitude de ces déplacements dépendent de façon connue des forces d'accélération ou de freinage ou de la force centrifuge. In a gearbox case, the oil which is in the bottom of this case tends to move, conventionally, going up along the wall of the latter when the vehicle accelerates, brakes or takes a turn. The direction and the amplitude of these displacements depend in known manner on the acceleration or braking forces or on the centrifugal force.
Dans le cas où cette boîte de vitesses est munie d'un système de pompage d'huile afin d'alimenter un circuit sous-pression, ce système de pompage comporte en général une crépine placée dans la partie inférieure du carter. In the case where this gearbox is provided with an oil pumping system in order to supply a pressure circuit, this pumping system generally comprises a strainer placed in the lower part of the casing.
A cause des déplacements mentionnés plus haut de l'huile dans le fond du carter, il existe donc d'une part un risque de désamorçage de la crépine et d'introduction d'air dans le circuit de pompage et d'autre part un risque de barbotage du mécanisme. Because of the movements mentioned above of the oil in the bottom of the casing, there is therefore on the one hand a risk of defusing the strainer and introduction of air into the pumping circuit and on the other hand a risk bubbling mechanism.
Le but de la présente invention est d'éviter, au moins en partie, les inconvénients ci-dessus. The object of the present invention is to avoid, at least in part, the above drawbacks.
Selon l'invention, le carter contenant un mécanisme, en particulier d'une boîte de vitesses de véhicule automobile, contenant de l'huile et dans la partie inférieure duquel est disposée une crépine d'aspiration d'un moyen de pompage d'huile, comprend une enceinte inférieure et une enceinte supérieure séparées par une cloison constituant au moins en partie une paroi supérieure de cette enceinte inférieure. Cette cloison présente un passage de communication entre lesdites enceintes, placé à distance de la paroi périphérique du carter de façon à entourer ledit passage. Ladite crépine d'aspiration est placée dans ladite enceinte inférieure et ledit mécanisme est placé dans ladite enceinte supérieure. According to the invention, the casing containing a mechanism, in particular of a motor vehicle gearbox, containing oil and in the lower part of which is arranged a suction strainer of an oil pumping means , comprises a lower enclosure and an upper enclosure separated by a partition constituting at least in part an upper wall of this lower enclosure. This partition has a communication passage between said enclosures, placed at a distance from the peripheral wall of the casing so as to surround said passage. Said suction strainer is placed in said lower enclosure and said mechanism is placed in said upper enclosure.
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
Selon l'invention, la face supérieure de ladite cloison est, de préférence, généralement inclinée en direction de son passage de communication. According to the invention, the upper face of said partition is preferably generally inclined in the direction of its communication passage.
Selon l'invention, ladite crépine d'aspiration peut présenter une partie qui s'étend au travers dudit passage de communication. According to the invention, said suction strainer may have a part which extends through said communication passage.
Selon l'invention, ledit carter comprend de préférence au moins deux parties dont le plan de joint traverse ledit passage de communication. According to the invention, said casing preferably comprises at least two parts, the joint plane of which passes through said communication passage.
Selon l'invention, ladite cloison s'étend de préférence dans le voisinage du niveau d'huile stagnant dans ledit carter. According to the invention, said partition preferably extends in the vicinity of the level of stagnant oil in said casing.
Selon l'invention, ladite cloison s'étend de préférence à faible distance au-dessus du niveau d'huile stagnant dans ledit carter. According to the invention, said partition preferably extends a short distance above the level of stagnant oil in said casing.
La présente invention sera mieux comprise à l'étude d'une boîte de vitesses de véhicule automobile décrite à titre d'exemple non limitatif et illustré par le dessin sur lequel : - la figure 1 représente une coupe transversale d'une boîte de vitesses selon la présente invention ;
- et la figure 2 représente une coupe longitudinale de la boîte de vitesses de la figure 1. The present invention will be better understood from the study of a motor vehicle gearbox described by way of nonlimiting example and illustrated by the drawing in which: - Figure 1 shows a cross section of a gearbox according to the present invention;
- And Figure 2 shows a longitudinal section of the gearbox of Figure 1.
En se reportant aux figures, on voit qu'on a représenté une boîte de vitesses 1 qui comprend un carter 2 qui comporte une cloison intérieure 3 ménageant dans ce dernier une enceinte inférieure 4 et une enceinte supérieure 5, cette cloison constituant la paroi supérieure de l'enceinte inférieure 4. Referring to the figures, it can be seen that a gearbox 1 has been shown which comprises a casing 2 which has an internal partition 3 providing in the latter a lower enclosure 4 and an upper enclosure 5, this partition constituting the upper wall of the lower enclosure 4.
Le mécanisme 6 de la boîte de vitesses 1, qui est représenté schématiquement par son encombrement général, est entièrement disposé dans l'enceinte supérieure 5. The mechanism 6 of the gearbox 1, which is represented schematically by its overall dimensions, is entirely disposed in the upper enclosure 5.
La cloison de séparation 3 présente un passage 7 de communication entre l'enceinte inférieure 4 et l'enceinte supérieure 5. The partition 3 has a communication passage 7 between the lower enclosure 4 and the upper enclosure 5.
Ce passage de communication 7 est placé à distance de la paroi périphérique 8 du carter 2 de telle sorte que cette dernière l'entoure et est prévu, dans l'exemple, en dessous et sur le côté du mécanisme 6. This communication passage 7 is placed at a distance from the peripheral wall 8 of the casing 2 so that the latter surrounds it and is provided, in the example, below and to the side of the mechanism 6.
Comme le montre la figure 1, la face supérieure de la cloison 3 est de préférence inclinée en direction du passage de communication As shown in Figure 1, the upper face of the partition 3 is preferably inclined towards the communication passage
<Desc/Clms Page number 3><Desc / Clms Page number 3>
7 de façon à constituer un déflecteur d'écoulement de l'huile vers l'enceinte inférieure 4 au travers de ce passage. 7 so as to constitute a deflector for the flow of oil to the lower enclosure 4 through this passage.
La boîte de vitesses 1 est en outre équipée, dans l'enceinte supérieure 5, d'un système de pompage d'huile 9. Ce système de pompage porte une crépine 10 installée dans l'enceinte inférieure 4 et portée par un bras d'écoulement 11 qui traverse librement le passage de communication 7. The gearbox 1 is further equipped, in the upper enclosure 5, with an oil pumping system 9. This pumping system carries a strainer 10 installed in the lower enclosure 4 and carried by an arm of flow 11 which freely crosses the communication passage 7.
Dans l'exemple représenté, le carter 2 comprend deux parties 2a et 2b qui sont accouplées par un plan de joint vertical 12 qui est placé de telle sorte que la partie 2b porte le système de pompage 9 sur ce plan de joint 12 et que ce plan de joint 12 divise la cloison 3 en deux parties délimitant entre elles le passage de communication 7. In the example shown, the casing 2 comprises two parts 2a and 2b which are coupled by a vertical joint plane 12 which is placed so that the part 2b carries the pumping system 9 on this joint plane 12 and that this joint plane 12 divides the partition 3 into two parts delimiting between them the communication passage 7.
Dans un état de fonctionnement normal, la boîte de vitesses 1 étant à l'horizontale, le niveau 13 de l'huile stagnant dans le carter 2 s'étend dans le voisinage de la cloison 3, de préférence à faible distance en-dessous de sa face inférieure. In a normal operating state, the gearbox 1 being horizontal, the level 13 of the oil stagnating in the casing 2 extends in the vicinity of the partition 3, preferably a short distance below its underside.
Grâce à la disposition qui vient d'être décrite, lorsque le véhicule automobile qui porte la boîte de vitesses 1 effectue des accélérations, des décélérations, ou prend un virage, l'huile que contient le carter 2 et qui stagne dans son enceinte inférieure 4 se déplace en correspondance mais se trouve confinée dans cette enceinte inférieure 4 grâce à la cloison de séparation 3 qui constitue un obstacle limitant la remontée de l'huile le long de la paroi périphérique 8 du carter 2. Thanks to the arrangement which has just been described, when the motor vehicle which carries the gearbox 1 accelerates, decelerates, or takes a turn, the oil which contains the casing 2 and which stagnates in its lower enclosure 4 moves in correspondence but is confined in this lower enclosure 4 thanks to the partition 3 which constitutes an obstacle limiting the ascent of the oil along the peripheral wall 8 of the casing 2.
De cette manière, d'une part la crépine 10 reste noyée dans l'huile stagnant dans l'enceinte inférieure 4 et ne risque pas de se désamorcer et, d'autre part la quantité d'huile risquant de stagner dans l'enceinte supérieure 5 au-dessus de la cloison 3 n'est pas suffisante pour que le mécanisme 6 risque de barboter. In this way, on the one hand the strainer 10 remains drowned in the oil stagnating in the lower enclosure 4 and does not risk being defused and, on the other hand the quantity of oil likely to stagnate in the upper enclosure 5 above the partition 3 is not sufficient for the mechanism 6 to risk bubbling.
La présente invention ne se limite pas à l'exemple ci-dessus décrit. Bien des variantes de réalisation sont sortir du cadre défini par les revendications annexées. The present invention is not limited to the example described above. Many alternative embodiments are outside the scope defined by the appended claims.
