Title:
RAILWAY VEHICLE WHEEL WITH IN-WHEEL MOTOR
Document Type and Number:
WIPO Patent Application WO/2013/001480
Kind Code:
A3
Abstract:
A railway vehicle wheel comprising a directly driving electric motor where the stator of the electric motor consists of a stator disk built onto the stationary tubular shaft, incorporated in the stator disc axially arranged soft magnetic cores with the stator windings, and the rotor consists of two rotor disks journalled to the tubular shaft via bearings, short circuiting winding or permanent magnets attached to the disks, ring surrounding the stator and fastening together the two disks, ring fastening the two rotor disks together and housing the stator furthermore the ring and the vehicle wheel rim are fastened together or consist of one joint piece, where the stator (5) width is less than the wheel rim width, and the stator (5) is liquid cooled, where the stator coils (17) are surrounded by cooling liquid channels (21) and/or the stator coils (17) are directly cooled, further on the surfaces of rotor disks (28, 29) radial cooling ribs (33) are shaped.
