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.
本发明涉及用于固定用于内燃发动机的排气后处理的部件的固定设备(10),其用于固定机动车辆内燃发动机的排气路径(34)中的用于排气后处理的至少一个部件(22)。部件(22)具有排气入口开口(26)和排气出口开口(28),排气出口开口在安装状态下相对于直线前进行驶方向布置在排气入口开口(26)的后面。根据本发明,固定设备(10)包括联接设备(12),联接设备可布置在排气路径(34)的区段(40)和至少一个排气入口开口(26)之间以确保它们之间的流体连接。如果高于预定大小的竖直向下指向的力(F)起作用,则联接设备(12)允许至少一个部件(22)的向下枢转移动(30),其中旋转平面(32)位于联接设备(12)中并且基本上位于与直线前进行驶方向平行的竖直平面中。
