Abstract

An electrically operated vehicle includes a braking resistor in a heat sink cover. The heat sink cover has an air throughflow body having vent openings and an air throughflow direction perpendicular to a direction of travel of the vehicle. The heat sink cover includes an inlet flap on an air inflow side and an outlet flap on an air outflow side. An opening mechanism opens and closes the flaps. In the closed state, the flaps are oriented along the direction of travel and obliquely to the air throughflow direction. In a plan view of the vent openings, the vent openings are at least 90% covered by the flaps in the closed state and at most 60% covered by the flaps in the opened state. The flaps are disposed symmetrically to a vehicle center axis, and the vent openings are oriented parallel to side surfaces of the vehicle.
