Cooling concept for brake means of a locomotive

摘要

Rail-guided traction vehicle (1) with an internal combustion engine (2) for generating a drive movement for the traction vehicle (1), an engine radiator (10) for cooling the internal combustion engine (2) and braking means (6, 5a, 5b, 17) for decelerating the traction vehicle ( 1), wherein the brake means (6, 5a, 5b, 17) via a filled with coolant brake cooling circuit (18, 19) with the engine radiator (10) of the internal combustion engine (2) are connected, wherein the braking means is an electric brake (6, 5a , 5b, 17) with a braking resistor (17) and the braking resistor (17) via the brake cooling circuit (18, 19) with the engine radiator (10) is connected, wherein the engine radiator (10) at least one in the brake cooling circuit (18, 19 ) integrated brake heat exchanger (19) and at least one in an engine cooling circuit (14, 15) integrated motor heat exchanger (14), characterized in that both the brake heat exchanger (19) and the engine heat exchanger (14) as an air / Liquid heat exchanger are designed, and that the engine radiator (10) is used for cooling two independent cooling circuits.
