Problems solved by technology

[0017] A simple solution for obtaining space for the deformation zone in the engine compartment is to increase the length of the front end of the vehicle, although increasing the number of non-deformable parts for exhaust aftertreatment, which will, however, significantly increase the weight of the motor vehicle, this is unacceptable

Embodiment Construction

[0064] figure 1 A part of the exhaust gas path 34 of an internal combustion engine (not shown) according to the invention and the fastening device 10 are shown in a schematic side view in the installed state. The internal combustion engine is part of a drive train of a motor vehicle comprising the (not shown) internal combustion engine and a not shown transmission. The internal combustion engine is arranged in an engine compartment 46 of the vehicle front end of the motor vehicle.

[0065] The exhaust path 34 includes a turbocharger 36 for attachment to the cylinder head of the internal combustion engine ( image 3 ), and includes a component 22 for exhaust aftertreatment, which is attached to said turbocharger 36 via a flange connection 38 on a section 40 of the exhaust path 34 . The component 22 for exhaust gas aftertreatment is formed by an exhaust gas catalytic converter with a metal housing 24 , in which a lambda probe 42 is arranged as a sensor of a lambda control syst...

Abstract

The invention relates to a fastening device (10) for fastening a component for exhaust gas aftertreatment of an internal combustion engine for fastening at least one component (22) for exhaust gas aftertreatment in an exhaust gas path (34) of a motor vehicle internal combustion engine. The component (22) has an exhaust gas inlet opening (26) and an exhaust gas outlet opening (28) which, in the installed state, is arranged behind the exhaust gas inlet opening (26) with respect to the straight forward direction of travel. According to the invention, the fastening device (10) comprises a coupling device (12) which can be arranged between a section (40) of the exhaust gas path (34) and the at least one exhaust gas inlet opening (26) in order to ensure a fluid connection therebetween. The coupling device (12) allows a downward pivoting movement (30) of the at least one component (22) if a vertically downward directed force (F) higher than a predetermined magnitude acts, with the plane of rotation (32) lying in the coupling device (12) and substantially in a vertical plane parallel to the straight advancing direction of travel.

Description

technical field [0001] The invention relates to a fastening device according to the preamble of claim 1 for fastening at least one component for exhaust gas aftertreatment in the exhaust gas path of a motor vehicle internal combustion engine. Furthermore, the invention relates to an exhaust gas path of a motor vehicle internal combustion engine according to the preamble of claim 9 , which exhaust gas path has at least one component for exhaust gas aftertreatment. Background technique [0002] In the field of motor vehicles with an internal combustion engine (combustion engine), components are known to be used in the exhaust gas path of the internal combustion engine for the recirculation of exhaust gas to the inlet side of the internal combustion engine and / or for the purification of the exhaust gas parts. [0003] Due to existing and future stricter exhaust gas regulations, there are high demands on the installation space of components for exhaust gas aftertreatment, e.g. ...
