Document Type and Number:
WIPO Patent Application WO/2024/045381
Kind Code:
A1
Abstract:
A railway vehicle bogie and a drive unit thereof. The drive unit comprises a permanent magnet direct drive traction motor (3-1) and a double-sided laminated coupling having a coupling output end (3-2), a coupling input end (3-3), and a transmission shaft sleeve (3-4). At the coupling output end, an outer side connecting disc (3-2-6) of the output end is fixedly connected to the transmission shaft sleeve by means of an end surface fluted disc, an inner side connecting disc (3-2-9) of the output end is connected to an output end of the permanent magnet direct drive traction motor, and the inner side connecting disc of the output end is connected to the outer side connecting disc of the output end by mean of a first lamination group (3-2-4). At the coupling input end, an inner side connecting disc (3-3-1) of the input end is fixedly connected to the transmission shaft sleeve by means of an end surface fluted disc, an outer side connecting disc (3-3-3) of the input end is connected to an axle (6-5) by means of an interference fit, and the inner side connecting disc of the input end is connected to the outer side connecting disc of the input end by means of a second lamination group (3-3-4). Compared with a conventional bogie, the total weight of the bogie is reduced by about 10%, traction energy consumption and wheel-rail abrasion are reduced, and the maintenance and repair period is prolonged.
