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.
Claims20
A vehicle, comprising:
- a vehicle body shell;
- at least one electrodynamic braking apparatus having at least one brake resistor;
- said at least one brake resistor forming a permanently closed portion of said vehicle body shell over which air flows externally during travel of the vehicle, or said at least one brake resistor being disposed in an immediate vicinity of said permanently closed portion;
- and
- wherein said permanently closed portion is free of mechanically movable parts for influencing the airflow, and heat is conducted away from said brake resistor outwardly to the surroundings via said permanently closed portion.
A brake resistor for a vehicle, the brake resistor forming a portion of a vehicle body shell that is permanently closed and over which air flows during a relative movement of the vehicle, or the brake resistor being disposed in an immediate vicinity of the portion of the vehicle body shell that is permanently closed, and wherein said permanently closed portion is free of mechanically movable parts for influencing the airflow.
A vehicle, comprising:
- a vehicle body shell;
- at least one electrodynamic braking apparatus having at least one brake resistor;
- said at least one brake resistor forming a permanently closed portion of said vehicle body shell over which air flows externally during travel of the vehicle, or said at least one brake resistor being disposed in an immediate vicinity of said permanently closed portion;
- wherein heat is conducted away from said brake resistor outwardly to the surroundings via said permanently closed portion;
- and
- wherein a braking energy fed during a time period of a braking from said electrodynamic braking apparatus into said at least one brake resistor is greater than a heat conductable away during the time period of the braking via the permanently closed portion to the surroundings, and wherein a maximum time period of the braking by said electrodynamic braking apparatus is limited by a maximum heat capacity of said brake resistor.
