<p>Air deflector (50) at a front corner (24, 44) of a cab (20) of a freight vehicle (10). According to the invention the air deflector comprises a vortex generator (50) which forms an angle of incidence, relative to an air flow (f) induced round the corner (24, 44) by movement of the vehicle, in order to convert part of the air flow (f) to a vortex flow (v)which follows a side (26) of the vehicle (10), said side being adjacent to the corner (24, 44),and prevents fouling(dirtying) of the side (26) from below.</p> |
