Ducting for a traction motor cooling system of a rail vehicle, traction motor cooling system and rail vehicle

摘要

Running gear 10 of a rail vehicle is provided with a first wheel set 14, a second wheel set 16, a first traction motor 32 for driving the first wheel set 14, a second traction motor 34 for driving the second wheel set 14, the first traction motor 32 being provided with a first cooling inlet 62, the second traction motor 32 being provided with a second cooling inlet 62 (64). A ducting 70 of a traction motor cooling system comprises a first duct 72 for connecting a first fan outlet 58 of a fan unit 46 with the first cooling inlet 62 (figs 2,3 not shown) and a second duct 74 for connecting a second fan outlet 60 of the fan unit 46 with the second cooling inlet 64 (figs 2,3 not shown). The second duct 74 has two parallel branches 84, 86, a portion of the first duct 72 being located between the two parallel branches 84, 86. The duct outlets78,90 line up with the motor inlets, flexible connections 66 (figs 2,3 not shown) link the ducting to the inlets of the motors. Figs 6-11 (not shown) disclose the glass reinforced resin plates arranged to create the ducting.
