Definitions
- the invention relates to an exhaust system for a drive unit formed by a transmission and a motor according to the preamble of claim 1.
- a suspension device for a dual-flow exhaust system of a motor vehicle which consists of a central holding part, on which elastically mounted support legs leading to the exhaust pipes of the exhaust system are fastened.
- the object of the invention is to design such a generic suspension device in a durable and stable manner despite the unit vibrations occurring in the motor vehicle.
- a fastening device for an exhaust pipe on a vehicle component in which a bracket of the fastening device has a shell element in the form of a cylinder segment which can be fastened to a substantially straight section of an exhaust pipe with the aid of holding means encompassing the exhaust pipe is.
- the fastening device for the exhaust system consists of a holding part with support legs which are fastened to the catalytic converter housing of the exhaust system via a clamp construction. Because the diameter of the catalytic converter housing is significantly larger than that of the exhaust pipes, this type of fastening enables the entire exhaust system to be suspended in a stable and permanent manner. Due to the features and measures listed in the subclaims, further advantageous refinements and developments of the exhaust system are possible.
- Another stabilizing measure that serves to suspend the entire exhaust system is that at least part of the catalytic converter housing is integrated in a rear silencer of the exhaust system.
- the support legs, to which the exhaust system is attached are advantageously designed as a lower, continuous strut, which is supported by two upper struts, each connecting the holding part and the clamps.
- the two upper struts are each connected to a damping element, which are coordinated in such a way that the vibrations of the aggregate or exhaust system can be effectively reduced.
- a holder is provided for connecting the fastening clamp to the lower and the two upper struts, to which the lower and the two upper struts are appropriately fastened by clamping or screwing.
- the holding part screwed on the end face to the gear unit of the drive unit is designed as a cast part or as a stamped part in the form of a one-piece carrier plate
- 1 is a perspective view of an exhaust system with a fastening device
- 2 shows a second perspective view of the exhaust system
- Fig. 3 is a first perspective side view of the fastening device
- Fig. 4 shows a second perspective view of the fastening device.
- the two-flow exhaust system for a 6-cylinder engine each has an exhaust manifold 2 and 4, each of which is attached with its flange section 6 or 8 to the cylinder head of an engine unit, not shown.
- the three individual pipes of the exhaust manifold 2 and 4 open into an exhaust gas collection pipe 10 or 12, to which a housing 14 or 16 of a starting catalytic converter is connected.
- An exhaust pipe 18 or 20 is flanged to each of the two starting catalytic converters 14, 16, each leading to a housing 22 or 24 in which a main catalytic converter is accommodated.
- the two main catalytic converters 22, 24 are each received in a rear silencer housing 26 or 28 or partially integrated therein.
- Both rear silencer housings 26 and 28 are fluidly connected to one another in terms of fluid technology via an upper connecting tube 30 and a lower connecting tube 32.
- the lower connecting pipe 32 is designed as a T-pipe piece, on the free connecting piece of which an exhaust pipe cover 34 is fastened.
- a fastening device 36 For the suspension or fastening of the entire exhaust system, a fastening device 36 is provided, which has a holding part, which is referred to below as a carrier plate 38.
- a lower pipe strut 42 is fastened to the carrier plate 38 with the aid of three pipe clamps 40a, b, c, and a fastening clamp 44 and 46, which surrounds the housing of the starting catalytic converter 14 and 16, is provided on the left and right support legs 42a and 42b.
- Two cup-shaped holding plates 48 and 50 for the two fastening clamps 44 and 46 are screwed to a holder 52 and 54, which are each formed by a bearing bush 56 or 58 formed out of the holder 52, 54 onto the respective end of the lower tubular strut 42 or the support legs 42a, 42b are clipped on.
- the clamping between the two components is generated by the fastening means 60, with which the holding plate 48 and 50 for the fastening clamps 44 and 46 on the holder simultaneously 52 or 54 is attached.
- the two holders 52 and 54 also each have an upper bearing bush 62 and 64, which each serve to receive one end of an upper tension strut 66 and 68, respectively.
- the other end of the two upper tension struts 66, 68 is screwed to the support plate 38 via a damping element 70 and 72.
- the two damping elements 70, 72 are designed as bushings, in which the upper tension strut 66, 68 is elastically supported or fastened in rubber elements.
- the tensile stress acting on the two upper tension struts 66, 68 can be adjusted; for this purpose, the end of the upper tension strut 66, 68 received in the upper bearing bush 62, 64 has a thread which is screwed into the bearing bush 62, 64.
- the screw connection is secured by a corresponding lock nut 74 and 76.
- the two clamps 44, 46 fastened to the catalytic converter housing 22, 24 are each secured by a clamp clamp 78 and 80, respectively.
- the carrier plate 38 which is designed as a cast or stamped part, has fastening openings 82 which are used for the end-side fastening of the carrier plate 38 to the housing of a transmission (not shown).
- the fastening device 36 for the exhaust system is provided, for example, for the Porsche Boxster model, which has a mid-engine arrangement, in which - as seen in the direction of travel - the engine is arranged in front of the transmission.
- the described fastening device for the exhaust system can also be fastened to the engine housing, chassis or body of the motor vehicle.
