Patent number: 10391868Abstract: 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.Type: GrantFiled: January 31, 2018Date of Patent: August 27, 2019Assignee: Siemens Mobility GmbHInventors: Claus-Ulrich Karipidis, Marcus Otto, Arnd Rueter, Gerald Amler
