Furthermore, during operation of the running gear, an airflow passes the wheel unit and the cooperating unit, in the height direction, at a first height level below the wheel unit axis. At least one air guide device is provided, the air guide device being arranged and adapted to guide an airflow portion of the airflow towards a section of the cooperating unit located at a second height level, the second height level being located above the first height level above the wheel unit axis.
