Description

Dispositif d'évacuation de gaz, notamment avec silencieux d'échappement, pour véhicules automobiles.Gas evacuation device, in particular with exhaust silencer, for motor vehicles.

L'invention concerne un dispositif d'évacuation de gaz, notamment avec silencieux d'échappement, pour véhicules automobiles. The invention relates to a gas evacuation device, in particular with an exhaust silencer, for motor vehicles.

Selon une pratique courante, une tubulure avec son silencieux d'échappement et le tube terminal, sont suspendus en différents points le long de la tubulure et du tube terminal sur des parties fixes du châssis du véhicule. According to current practice, a tube with its exhaust silencer and the end tube are suspended at various points along the tube and the end tube on fixed parts of the chassis of the vehicle.

Les moyens de suspension sont constitues, par exemple, par des moyens de serrage incluant une console et un étrier en forme de U qui s'étend autour de la tubulure et qui est fixé à la console. The suspension means are constituted, for example, by clamping means including a console and a U-shaped stirrup which extends around the tube and which is fixed to the console.

La pose ou la dépose de la tubulure, de la console et de l'étrier prennent du temps et nécessitent souvent le remplacement des organes de fixation. Installing or removing the tubing, console and caliper takes time and often requires replacement of the fasteners.

La publication FR-A-2165679 concerne un moyen de suspension d'une tubulure d'échappement réalisé à partir de mâchoires élastiques disposées le long du châssis. The publication FR-A-2165679 relates to a means for suspending an exhaust pipe made from elastic jaws arranged along the chassis.

Par contre, lorsque le dispositif d'échappement porte des moyens d'accrochage des organes de fixation, il arrive par suite d'imprécisions de réalisation, que ceux-ci ne soient plus en correspondance avec les ancrages prévus sur le châssis. On the other hand, when the exhaust device carries means for attaching the fastening members, it happens as a result of imprecision in construction, that these are no longer in correspondence with the anchorages provided on the chassis.

Il est nécessaire, dans ce cas, de réaliser des tubulures spéciales pour remédier au défaut signalé,
L'invention a pour objet de remédier à l'inconvénient précité et concerne un dispositif d'évacuation de gaz d'échappement pour véhicules à moteur ayant un châssis comportant, notamment sur un tronçon de tubulure, d'entrée, un silencieux d'échappement raccordé audit tronçon et un tube terminal de sortie rigidement relié audit silencieux d'échappement et des ancrages de moyens de fixation, respectivement disposés sur lesdits tronçons de tubulure d'entrée et tube terminal de sortie.In this case, special tubing is necessary to remedy the fault indicated,
The object of the invention is to remedy the aforementioned drawback and relates to an exhaust gas evacuation device for motor vehicles having a chassis comprising, in particular on a section of tubing, inlet, an exhaust silencer connected to said section and an outlet end tube rigidly connected to said exhaust silencer and anchors of fixing means, respectively arranged on said sections of inlet pipe and outlet end tube.

Selon l'invention, la tubulure d'entrée comporte un dispositif permettant l'ajustement de sa longueur consistant en un montage télescopique du tronçon de tubulure avec un manchon d'entrée du silencieux d'échappement, complété par un moyen de blocage dudit tronçon, par rapport audit manchon à la suite dudit ajustement. According to the invention, the inlet pipe comprises a device allowing the adjustment of its length consisting of a telescopic mounting of the pipe section with an inlet sleeve of the exhaust silencer, supplemented by a means for blocking said section, with respect to said sleeve following said adjustment.

Le dispositif ainsi réalisé peut être dimensionnellement ajusté pour la mise en correspondance des moyens de fixation avec les ancrages fixes prévus sur le châssis et l'utilisation d'un système d'échappement standard adapté aux différents écartements d'ancrages prévus sur le châssis. The device thus produced can be dimensionally adjusted for matching the fixing means with the fixed anchors provided on the chassis and the use of a standard exhaust system adapted to the different spacings of anchors provided on the chassis.

D'autres caractéristiques et avantages du dispositif apparaîtront à la lecture de la description qui suit, faite en référence au dessin annexé, dans lequel
la figure 1 est une représentation schématique du dispositif :d'évacuation des gaz d'un moteur de véhicule automobile avec ses moyens de fixation au châssis;
la figure 2 est une représentation agrandie de l'ensemble constitué par le tronçon de tubulure d'entrée du silencieux d'échappement et du tube terminal conforme à l'invention.Other characteristics and advantages of the device will appear on reading the following description, made with reference to the appended drawing, in which
Figure 1 is a schematic representation of the device: exhaust gas from a motor vehicle engine with its fixing means to the chassis;
Figure 2 is an enlarged representation of the assembly consisting of the inlet pipe section of the exhaust silencer and the end tube according to the invention.

Le véhicule automobile représenté par ses éléments de châssis 1, possède un moteur 2 avec un collecteur d'échappement 3 qui évacue les gaz d'échappement dans un dispositif 4 qui peut comprendre une tubulure d'échappement 5 qui est raccordée à son extrémité d'entrée, à la sortie 6 du collecteur 3. La tubulure 5 conduit les gaz au manchon d'entrée 7 du silencieux d'échappement 8, lequel évacue les gaz détendus dans un tube terminal de sortie 10 rigidement relié au silencieux 8. The motor vehicle represented by its chassis elements 1 has an engine 2 with an exhaust manifold 3 which discharges the exhaust gases in a device 4 which may include an exhaust manifold 5 which is connected to its end inlet, at outlet 6 of manifold 3. The pipe 5 leads the gases to the inlet sleeve 7 of the exhaust silencer 8, which evacuates the expanded gases in an outlet terminal tube 10 rigidly connected to the silencer 8.

Le tube terminal de sortie 10 et la tubulure 5 portent respectivement des crochets 11,12 destinés à recevoir des moyens de fixation aux ancrages fixes 13,14 prévus sur le châssis. The outlet terminal tube 10 and the tubing 5 respectively carry hooks 11, 12 intended to receive means for fixing to the fixed anchors 13, 14 provided on the chassis.

Selon l'invention, une disposition constructive autorise l'ajustement de la longueur du dispositif d'évacuation des gaz en fonction des différents écartements des ancrages 13,14 rencontrés sur les châssis des véhicules. A cet effet, la tubulure d'entrée 5 et le manchon d'entrée 7 du silencieux d'échappement réalisent un montage télescopique complété par un moyen de blocage constitué, à titre d'exemple, par un collier 15. According to the invention, a constructive arrangement allows the length of the gas discharge device to be adjusted as a function of the different spacings of the anchors 13, 14 encountered on the chassis of the vehicles. To this end, the inlet pipe 5 and the inlet sleeve 7 of the exhaust silencer carry out a telescopic assembly completed by a locking means constituted, for example, by a collar 15.

Le dispositif d'échappement conforme à l'invention, permet ainsi de réaliser les fixations nécessaires. Par suite de la disposition constructive à montage télescopique des éléments du dispositif, il est également possible de réduire considérablement les tensions exercées sur les moyens de fixation et de prolonger la durée de vie desdites fixations, en l'absence de tout effort de fatigue préjudiciable à la tenue mécanique de celles-ci.  The exhaust device according to the invention thus makes it possible to make the necessary fastenings. As a result of the constructive arrangement with telescopic mounting of the elements of the device, it is also possible to considerably reduce the stresses exerted on the fastening means and to extend the life of said fastenings, in the absence of any fatigue effort detrimental the mechanical strength of these.
