Coupling device of an intake system of a charged internal combustion engine, charge air duct, intake system, duct part and clamping ring

摘要

The present invention relates to coupling device (34) of an intake system (10) of a charged internal combustion engine (12), in particular of a motor vehicle, a charge air duct, an intake system, a duct part and a clamping ring. The coupling device (34) is for coupling at least one first duct part (30) of a charge air duct (14) with at least one second duct part (32) of the charge air duct (14). The coupling device (34) is comprising a female joining section (40) at an end of the at least one first duct part (30) and a male joining section (38) at an end of the at least one second duct part (32). At least the female joining section (40) of the at least one first duct part (30) is at least partly flexible. The male joining section (38) can at least partly be plugged in the female joining section (40). A clamping ring (46) designated for engaging around the connected joining sections (38, 40) of the duct parts (30, 32) with regard to a coupling axis (36). The clamping ring (46) is comprising at least one fastener part (54) of at least one fastener (52) for engaging with at least one corresponding fastener part (50) of the at least one second duct part (32). The clamping ring (46) further is comprising at least one clamping part (42, 44) of a clamping connection (58) for pressing at least a part of the female joining section (40) at least against the male joining section (38).
