Vehicle with a closure system for regulating the air flow through the grille opening

Vehicle (30), comprising: an internal combustion engine (34), which is cooled by a fluid circulated; a heat exchanger (36) which is adapted so that it cools the fluid by means of an air flow after the fluid has cooled the internal combustion engine (34); a grille opening (32) is positioned so that it can be flowed through from the back flowing to the heat exchanger (36) air stream; and a closure system (10) for regulating an air flow through the grille opening (32), said closure system (10) comprising: a first air valve element (12A) having a first axis of rotation (16A), wherein the first air flap element (12A) is adapted so that it rotates about the first axis of rotation (16A); a second air valve element (14A) having a second axis of rotation (18A), wherein the second air valve element (14A) is adapted so that it rotates about the second axis of rotation (18A); and a flexible drive member (26) which connects the first air flap element (12A) and the second air valve element (14A) with each other, thereby to synchronize the rotation of the first and second air flap element (12A, 14A) substantially, wherein the flexible drive member (26 ) has the shape of a tube (with a first end to a (the first air flap member 12A) about the first axis of rotation 16A) formed around projection is fitted and with an end opposite the first end second end to one (the second air flap element 14A) to the second axis of rotation (18A) formed around projection is fitted.
