Title: Bogie mounting
Inventor: DOWLING JOHN
IPC: B61F1/14
Filed: 1986-04-21
Abstract: A high speed powered railway bogie arrangement includes a traction motor assembly comprising two traction motors 1 mounted from the locomotive body so as to be isolated from, but to swivel with, the bogie. The motor drive shafts may be parallel to the axles 21 of the bogie wheelsets. A flexible drive train accommodates relative motion between the traction motor assembly and the bogie wheelsets. A linkage between the bogie and the traction motor assembly allows for some degree of lost motion between swivelling of the bogie and swivelling of the traction motor assembly. By decoupling the mass of the traction motors 1 from the bogie, "hunting" disturbances of the bogie, which tend to arise at high speeds, are minimised. A Watt linkage between the bogie and the locomotive body allows the bogie lateral freedom of movement with respect to the locomotive body. <IMAGE>
