Recuperative brake on a vehicle

A suction tube arrangement includes a suction tube having a suction tube opening and an actuating shaft which is received in the suction tube. The actuating shaft has a base body made of a first material and an actuating shaft body made of a second material and at least partially applied on the base body. The base body or the actuating shaft body forms at least one cover element to open or close the suction tube opening as a function of a rotation of the actuating shaft. An actuating element is at least partially enclosed by the actuating shaft body for actuating the actuating shaft.
