Abstract: A braking resistance device for a vehicle has a plurality of braking resistance elements each having a tubular heat-conducting casing. A heat-conducting and electrically insulating material is disposed in the casing. An electrical conductor is embedded in the insulating material over a majority of the longitudinal extent of the casing. Furthermore, the braking resistance device has a stacking arrangement which is designed to be passively cooled. The stacking arrangement has a plurality of layers which are arranged one above the other in a stacking direction and each including the braking resistance elements of the plurality of braking resistance elements which are arranged substantially parallel to one another.

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.

Abstract: A vehicle, such as a rail vehicle, has an electrodynamic braking apparatus with at least one brake resistor. The at least one brake resistor forms a portion of the vehicle body shell that is permanently closed and over which air flows on the exterior, in particular, during travel of the vehicle. In the alternative, the brake resistor is arranged in the immediate vicinity of the permanently closed portion. The brake resistor conducts away heat outwardly to the environment via the permanently closed portion. There is also described a brake resistor for a vehicle, in particular for a rail vehicle, which is configured accordingly.

Abstract: A vehicle has at least one component which is cooled by a cooling air mass flow delivered from a conveying device such as a fan or a spoiler. A nominal value is predetermined for the cooling air mass flow which, for an assumed maximum thermal loading of the component, cools adequately for operation of the component. A control device controls an intensity of the cooling air mass flow and dimensions it, taking into consideration thermal demands of the component at least in an upper driving speed range, such that a sum of a power consumption of the component, of the conveying device and of a portion of a traction power of the vehicle that is allotted to the delivery of the cooling air mass flow is smaller than a sum of the power consumption of the component, the conveying device and the portion that is allotted to the delivery of the cooling air mass flow at the predetermined nominal value thereof, of a traction power of the vehicle.

Abstract: A controlled-route vehicle, in particular a train, includes at least one air passage disposed in a wall of the controlled-route vehicle. The air passage has an inlet opening, disposed in an outer side of the wall, for letting air into the air passage, an outlet opening, disposed in an inner side of the wall, through which the air can be let out into an interior of the controlled-route vehicle, and a section which tapers in the direction of the outlet opening and is formed by an inner wall side of the wall. As a result, improved transport of the air into the interior of the controlled-route vehicle can be achieved in a structurally simple and inexpensive manner.

Abstract: A covering for a bogie of a rail vehicle lends the entire rail vehicle a low aerodynamic tractive resistance in the region of the bogie. The novel covering has a peripheral wall for surrounding the bogie and a fastening device for rotationally guiding the peripheral wall at the upper edge thereof on a superstructure of the rail vehicle. The covering is covered at the lower edge of the peripheral wall by an underbody-like end member that has fastening means for attaching the same to the bogie.
