Abstract: An exhaust gas treatment system to be fitted on a chassis of an automotive vehicle. The system includes a selective catalytic reduction device and a gaseous fluid supplying device. The gaseous fluid supplying device includes a tank containing a material which is capable of retaining gaseous fluid by absorption and/or adsorption and/or formation of chemical complexes, and of releasing previously retained gaseous fluid. The gaseous fluid supplying device further includes a gaseous fluid delivery system capable of causing the release of gaseous fluid by the material and an injection system for injecting gaseous fluid upstream from the selective catalytic reduction device. Additionally the system may include a particulate filtering device. The particulate filtering device, the selective catalytic reduction device and the gaseous fluid supplying device are arranged within a same frame which includes fastening means for fastening the frame to the vehicle chassis.

Abstract: A chassis frame includes a first chassis subsection having a first width w and at least a second chassis subsection adjacent to the first chassis subsection having a width W greater than the width w of the first chassis subsection. Each chassis subsection includes a right and a left parallel C shaped frame rail inwardly open towards each other and extending longitudinally; the chassis further includes a right—respectively left—interface bracket connecting two consecutive right—respectively left—frame rails belonging to two adjacent chassis subsections; the interface bracket maintains a transversal distance D between the said two consecutive right—respectively left—frame rails belonging to two adjacent subsections and further includes at least one mounting unit on which at least one vehicular operational part is attached.

Abstract: A diaphragm clutch mechanism for a motor vehicle engine having a friction lining adapted to be clamped with an annular diaphragm between a reaction plate and a pressure plate. A cover fixed to the reaction plate and integral in rotation with the pressure plate which is also mobile in axial translation relative to the reaction plate, and an assist mechanism includes a Belleville washer which co-operates with the diaphragm so that the load exerted on the pressure plate should be substantially constant whatever the degree of wear of the friction lining when the clutch mechanism is in engaged position. The assist Belleville washer is supported on the diaphragm or on the cover that forms a front stop. The assist Belleville washer is supported on a rear stop borne by the cover so as to be slightly stressed when the clutch mechanism is in the released position.

Abstract: A friction clutch equipped with a flexible flywheel. The friction clutch has at least two natural resonant frequencies below a certain frequency. The ratio of a second resonant frequency relative to a first resonant frequency is at least 1.5. The friction clutch of the present invention reduces noise and increases useful life.

Abstract: A double damping flywheel for a motor vehicle, comprising two coaxial masses mounted movably in relation to one another in opposition to a resilient member and a friction member (51-55). A bearing part (60) is provided between the masses, integral with one of the said masses, and for the most part receives the friction means. The bearing part (60) comprises a shoulder engaging (60B) with teeth (62) designed to be edged so as to keep a stack of washers (51-55) in position, each tooth (62) being framed by stabilising lugs (70) allowing the bending operation to be assisted by a matrix of tools.

Abstract: A flywheel comprising a first and second coaxial body (1, 2) movably mounted in relation to one another against an elastic member (8) and friction device (50, 150). The first body (1) is mounted to a drive shaft while the second body (2) includes a reaction plate (21) for a friction clutch. The first body (1) includes a member (60) on its outer periphery, a stiffener, extending close to the second body (2). The friction devices (50, 150) are inserted between the member (60) and the second body (2). The flywheel is adapted for use with a motor vehicle.

Abstract: A flywheel having two coaxial masses (1,2) mounted so as to move with respect to one another and counter to a radially acting elastic member (3) and an axially acting friction member (4) disposed therebetween. The first mass (1) may be fixed, with respect to rotation, to a drive plate. The second mass (2), is releasably fixed, with respect to rotation, on a driven shaft. The friction member 4 is supported by the first mass 1 and disposed axially between the first mass and the elastic member 3.

Abstract: A reaction plate for a friction clutch comprising a cover which includes a mounting insert fixed in the body of the reaction plate. The insert includes, on the outer periphery of the reaction plate, a projecting area for mounting the friction clutch cover.

Abstract: A damped flywheel comprising two coaxial masses (1, 6) mounted for movement of one with respect to the other against the action of springs (150) and of a friction member (170), in which the inertia of the first mass (1) is increased by locating the resilient member (150) entirely inwardly, in the radial sense, of the friction face (125) of the clutch itself.

Abstract: A double damped flywheel having two coaxial masses. A first mass is fixed to a driving shaft of a central portion (20) made of sheet metal and a peripheral massive portion (22) connected to the periphery of the central portion.

Abstract: A double damper flywheel having a rotating mass including a plurality of annular parts, a first part carrying a hub having a bearing for the rotation of a second mass and another annular part having an annular plate provided with an axially oriented external cylindrical skirt. The plate includes a first group of radial lugs for fixing to the first annular part and a second group of radial lugs for mounting springs acting between the two masses. The second group of lugs are offset axially and circumferentially with respect to the first group of lugs.

Abstract: The damping flywheel includes at least one cartridge (10) pivotally mounted on first and second coaxial masses. At least one elastic member (8) is mounted in the cartridge having, for mounting the elastic member (8), a web (3) and two guide components (4, 5) disposed axially on each side of the web. The web and the guide components (4, 5) have housings (82, 81) for mounting the elastic member (8). Friction means are mounted within the cartridge.

Abstract: A damping device (10) of the type comprising damping means which are disposed between two coaxial rotating inertia parts (12, 14), and which comprise at least one block of elastically deformable material (56A, 58A, 56B, 58B), which is interposed between the two rotating parts (12, 14), and on which there acts a mechanism which comprises a cam (46A, 46B) and a cam follower element (64A, 64B), characterised in that the cam (46A, 46B) is formed on a tilting member (42A, 42B) which is articulated with respect to a first one (12) of the two rotating parts, and in that the cam follower element is a roller (64A, 64B) which is carried by the second rotating mass (14, 66A, 66B), and which cooperates with the cam (46A, 46B) when the two parts (12, 14) rotate with respect to each other.
