Running gear for a rail vehicle

The invention relates to a running gear for a rail vehicle, comprising a wheel unit (103) and a cooperating unit (107). The running gear defines a longitudinal direction, a transverse direction and a height direction, while the wheel unit (103) defines a wheel unit axis. The cooperating unit (107) is connected to the wheel unit (103) and cooperates with the wheel unit (103) during operation the running gear to drive and/or brake the wheel unit (103). Furthermore, during operation of the running gear, an airflow (MF) passes the wheel unit (103) and the cooperating unit (107), in the height direction, at a first height level below the wheel unit axis. At least one air guide device (111) is provided, the air guide device (111) being arranged and adapted to guide an airflow portion (PF) of the airflow (MF) towards a section of the cooperating unit (107) located, in the height direction, at a second height level, the second height level, in the height direction, being located above the first height level, in particular, above the wheel unit axis.
