Abstract

Gas scrubber includes a first stage wherein steam and/or atomized water is injected into the gas from nozzles arranged within a vertical flue stack. In a second stage, the wetbed gas is centrifugally compressed within an enclosed rotating structure arranged on the top of the stack, so as to condense water together with particulate. The rotary structure includes upper and lower surfaces which converge radially outwardly. The surfaces carry annular screens for reducing slippage between the gas and the rotor structure. A further screen is arranged therebetween. Circumferentially spaced impeller blades are also provided within the structure. Water is discharged from the rotor structure by tangentially arranged outlets within a ring sandwiched between the outer peripheries of the upper and lower surfaces. The rotor structure is surrounded by a housing having outlets for water leading to drain. An outer housing incorporates a further screen.

Description

La présente invention a pour objet un double essieu à roues indépendantes. The present invention relates to a double axle with independent wheels.

L'invention se rattache au secteur technique des dispositifs de suspension de véhicules, et plus particulièrement aux roues de véhicules, aux essieux et à l'amélioration de l'adhérence des roues. The invention relates to the technical sector of vehicle suspension devices, and more particularly to vehicle wheels, axles and the improvement of the grip of the wheels.

Selon l'invention, on a voulu améliorer les conditions d'absorption par effacement des inégalités de terrain, quel que soit l'état des surfaces de revêtement des routes. Pour certains matériels existants, on a constaté que le résultat recherché et précité, n'était pas obtenu par suite de l'état des surfaces de revêtement, et que l'on obtenait, au contraire, le décollement de l'essieu. According to the invention, it was desired to improve the absorption conditions by erasing uneven terrain, whatever the condition of the road surface surfaces. For certain existing materials, it has been found that the desired and aforementioned result was not obtained as a result of the condition of the coating surfaces, and that, on the contrary, the axle was detached.

Selon une première caractéristique, le double essieu se compose par exemple d'un faux châssis dont chaque longeron lat6- ral présente à un endroit approprié, un axe d'articulation ; le dit axe autorise l'articulation libre en rotation, de deux bras identiques profilés, indépendants et disposés de part et d'autre de l'axe d'articulation, les deux bras étant montés et engagés par l'de leurs extrémités, sur ledit axe d'articulation, tandis que l'autre extrémité autorise la fixation des moyeux de roues ; les deux bras présentant à un endroit approprié, intermédiaire aux extrémités, un point d'attache et de fixation des extrémités d'un ressort travaillant en traction, et assurant la liaison élastique entre les deux leviers. According to a first characteristic, the double axle consists for example of a subframe, each lateral spar of which has, at an appropriate location, a hinge pin; the said axis authorizes the free articulation in rotation, of two identical profiled arms, independent and arranged on either side of the articulation axis, the two arms being mounted and engaged by the of their ends, on the said hinge pin, while the other end allows the fixing of the wheel hubs; the two arms having at a suitable location, intermediate at the ends, a point of attachment and fixing of the ends of a spring working in traction, and ensuring the elastic connection between the two levers.

Selon une autre caractéristique, le positionnement des points de fixation et d'ancrage des extrémités du ressort, est variable et déterminé en fonction de la charge à supporter. According to another characteristic, the positioning of the fixing and anchoring points of the ends of the spring is variable and determined as a function of the load to be supported.

Ces caractéristiques et d'autres encore ressortiront de la suite de la description. These characteristics and others will emerge from the following description.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

Comme représenté figure 1, l'essieu comprend par exemple un faux châssis avec deux longerons latéraux 1 - 2 et un élément transversal i. En variante, on peut avoir deux longerons reliés par un axe transversal approprié formant directement essieu. Chaque extrémité de l'essieu est conformée pour autoriser le centrage et la libre rotation des extrémités formant têtes tournantes 41 de de deux bras profilés et opposés 4 - 5, symétriques de préfé- rence et indépendants l'un de l'autre, constituant ainsi les cotés d'une triangulation isocèle.A titre d'exemple non limitatif, l'extrémité supérieure 41 - 5 de chaque bras formant tête, presente un alésage 42 - 52, transversal, pour le libre engagement d'un axe d'articulation 6 monté solidaire de l'essieu, tandis que des roulements à galets coniques l ou autres, permettent l'articu- lation en rotation des bras profilés. Une bague antifriction inter médiaire 8, telle une butée à billez est intercalée entre les extrémités 4 51 des bras, pour permettre leur rotation l'une par rapport à l'autre. Des moyens bien connus assurent suivant les courses extrêmes, la butée en position des éléments précités sur l'axe d'articulation 6. As shown in FIG. 1, the axle comprises for example a subframe with two lateral beams 1 - 2 and a transverse element i. Alternatively, one can have two beams connected by a suitable transverse axis directly forming the axle. Each end of the axle is shaped to allow centering and free rotation of the ends forming rotating heads 41 of two profiled and opposite arms 4 - 5, preferably symmetrical and independent of each other, thus constituting the sides of an isosceles triangulation. By way of nonlimiting example, the upper end 41 - 5 of each arm forming a head, has a bore 42 - 52, transverse, for the free engagement of a hinge pin 6 mounted integral with the axle, while tapered roller bearings l or others, allow the articulation in rotation of the profiled arms. An intermediate median anti-friction ring 8, such as a ball stop is interposed between the ends 451 of the arms, to allow their rotation relative to one another. Well-known means ensure, according to the extreme strokes, the stop in position of the aforementioned elements on the articulation axis 6.

Selon une autre caractéristique de l'invention, les deux bras 4 et q, en toute section plane ou creuse, sont profilés et coudés selon un angle, pour augmenter l'empattement des roues. According to another characteristic of the invention, the two arms 4 and q, in any flat or hollow section, are profiled and bent at an angle, to increase the wheelbase.

;'autre extrémité 43 - 53 desdits bras, présente des moyens autorisant la fixation des fusées de roues et par suite, des moyeux 2 - 19 équipés ou non des dispositifs de freinage. the other end 43 - 53 of said arms, presents means authorizing the fixing of the wheel spindles and consequently, hubs 2 - 19 equipped or not with braking devices.

En outre, les deux bras sont reliés l'un à l'autre, par un ressort hélicoïdal 11, convenablement taré, compte tenu de la charge à supporter et travaillant en extension, monté de manière à assurer le rappel permanent des bras 4 - 5 en position de rapprochement. tes extrémités 111 - 112 du ressort, sont fixées sur des points d'ancrage 12 - 13 fixes ou réglables en positions longi tudînales disposes en des points variables des bras 4 compte tenu des variations extrêmes de charge, et par conséquent de l'amplitude de debattement desdits bras 4 - 2. De manière connue, et comme exposé dans une autre Demande de Brevet dont le demandeur est également titulaire, les spires extrêmes du ressort 11, sont visées et logées dans une gorge hélicoldale d'une tête cylindrique 141 relative à un axe support transversal 14, fixé sur chaque levier profilé 4 - 5, comme cela apparait bien à la figure 5 des dessins. In addition, the two arms are connected to each other, by a helical spring 11, suitably calibrated, taking into account the load to be supported and working in extension, mounted so as to ensure the permanent return of the arms 4 - 5 in the approaching position. your ends 111 - 112 of the spring, are fixed on anchor points 12 - 13 fixed or adjustable in longitudinal positions arranged at variable points of the arms 4 taking into account the extreme variations in load, and consequently the amplitude of deflection of said arms 4 - 2. In a known manner, and as explained in another Patent Application of which the applicant is also the holder, the extreme turns of the spring 11, are targeted and housed in a helical groove of a cylindrical head 141 relating to a transverse support pin 14, fixed to each profiled lever 4 - 5, as appears clearly in FIG. 5 of the drawings.

Comme illustré schématiquement figures 4 et 5, les points de fixation des extrémités du ressort à boudin 11, peuvent être réglables de manière à obtenir le réglage de leur tension, pour agir en position de rappel sur les bras 4 et 5. A titre d'exemple non limitatif, les extrémités du ressort peuvent être fixées sur des axes-supports 15 montés d'une manière réglable, sur des coulisseaux se déplaçant dans des fentes 17 formées dans l'épaisseur des bras 4 et 5, des éléments de maintien et de fixation étant rapportés. Selon une autre variante, les logements de positionnement variable des axes-supports 15, peuvent être disposés indépendamment et en succession pour le réglage de la suspension. As illustrated schematically in Figures 4 and 5, the attachment points of the ends of the coil spring 11, can be adjustable so as to obtain the adjustment of their tension, to act in the return position on the arms 4 and 5. As nonlimiting example, the ends of the spring can be fixed on support pins 15 mounted in an adjustable manner, on slides moving in slots 17 formed in the thickness of the arms 4 and 5, holding and fixing being reported. According to another variant, the variable positioning housings of the support axes 15 can be arranged independently and in succession for adjusting the suspension.

Selon une autre variante de réalisation illustrée figure 7, les extrémités 181 du ressort hélicoïdal 18, présentent une forme en anneau ou boucle, et autorisent l'engagement et le positionnement d'une bague en nylon 19 ou similaire, l'extrémité ainsi agencée du ressort venant s'engager et se centrer sur 1' axe 19 solidaire des bras profilés 4 ou 5.  According to another alternative embodiment illustrated in FIG. 7, the ends 181 of the helical spring 18 have a ring or loop shape, and allow the engagement and positioning of a nylon ring 19 or the like, the end thus arranged of the spring coming to engage and center on one axis 19 secured to the profiled arms 4 or 5.

Selon une autre caractéristique de l'invention, des butées 20 sont disposées respectivement sur le bras oscillant et sur le longeron du faux châssis en regard, pour assurer une limitation de course du bras oscillant par rapport au faux chassis. Le positionnement des butées est établi en fonction du débattement voulu des roues. According to another characteristic of the invention, stops 20 are disposed respectively on the swinging arm and on the side member of the opposite subframe, in order to limit the travel of the swinging arm relative to the subframe. The positioning of the stops is established according to the desired travel of the wheels.

On a prévu également de disposer des amortisseurs, un pour chaque bras profilé, dont une extrémité prend appui sur le faux chassis, et l'autre extrémité, sur le bras profilé. Provision has also been made to have shock absorbers, one for each profiled arm, one end of which rests on the subframe, and the other end, on the profiled arm.

On comprend bien l'intérêt de telles dispositions. tes deux roues sont independantes, tout en étant reliées entre elles par un ressort travaillant essentiellement en traction. Comme illustré figures 2 et 3, on obtient un meilleur effacement des roues selon le profil des routes et quelle que soit la vitesse de déplacement du véhicule avec un report de l'effort d'adhérence sur l'autre roue non sollicitée par une déformation ou anfractuosité de la route. il est bien certain que la triangulation donnée par le positionnement des trois axes, axe d'articulation 6, axe des roues 9 - 10 et points d'ancrage des extrémités du ressort, peut varier en fonction de la charge de l'essieu. -
On a illustré figure 6, une variante de réalisation, les deux bras 21 - 22 étant essentiellement dans le même plan, tandis que leur extrémité 211 - 221 'engageant sur l'axe d'articulation, est déportée transversalement.We understand the interest of such provisions. your two wheels are independent, while being connected to each other by a spring working essentially in traction. As illustrated in FIGS. 2 and 3, a better erasure of the wheels is obtained according to the profile of the roads and whatever the speed of movement of the vehicle with a transfer of the grip force on the other wheel not requested by a deformation or road crevice. it is certain that the triangulation given by the positioning of the three axes, articulation axis 6, wheel axis 9 - 10 and anchoring points of the ends of the spring, can vary depending on the axle load. -
Illustrated in Figure 6, an alternative embodiment, the two arms 21 - 22 being essentially in the same plane, while their end 211 - 221 'engaging on the hinge axis, is offset transversely.

L'invention ne se limite aucunement i celui de ces modes d'application, non plus qu'à ceux des modes de réalisation de ces diverses parties ayant plus spécialement été indiqués ; elle en embrasse au contraire toutes-les variantes.  The invention is in no way limited to that of these modes of application, nor to those of the embodiments of these various parts which have been more particularly indicated; on the contrary, it embraces all of its variants.
