The invention relates to a fastening device (10) for fastening at least one component (56) for exhaust gas aftertreatment of an internal combustion engine of a powertrain, having at least one fastening device (24; 32; 40). According to the invention, the at least one fastening device (24; 32; 40) can additionally be fixedly attached to a chassis (72) of the motor vehicle, in the normal installed state, a force introduction path parallel to the straight forward direction of travel is not formed between the at least one component (56) and the chassis (72), the force introduction path (20) is formed if the relative distance of the at least one component (56) relative to the chassis (72) in the straight forward direction of travel at least reaches a predetermined value.
本发明涉及一种紧固设备(10),所述紧固设备用于紧固用于动力传动系统的内燃发动机的排气后处理的至少一个部件(56),所述紧固设备具有固定附接到至少一个部件(56)的至少一个紧固装置(24;32;40)。根据本发明,所述至少一个紧固装置(24;32;40)另外能够固定附接到所述机动车辆的底盘(72),在正常安装状态下不在所述至少一个部件(56)和所述底盘(72)之间形成与直线前进行驶方向平行的力引入路径,并且如果所述至少一个部件(56)在所述直线前进行驶方向上相对于所述底盘(72)的相对间距至少达到预定值,则形成这种力引入路径(20)。
