Traditional gearbox drives have a gear coupling structure of 10 Due to its absence, this application of the bogie is necessary for the drive unit. (3) a simplified drive unit which reduces noise (3) It has a structure; permanent magnet direct drive traction. motors (3-1), elastic body suspension structure and flexible axle suspension structure (double sides of stacked part coupling 15 (mounted to the axle via) is mounted by, so It transmits torque and reduces the unsprung mass of the bogie. The total weight of the bogie is approximately 10% compared to a traditional bogie. This reduces traction energy consumption and wheel-rail reduces wear and tear, extends the maintenance and repair cycle, and thus 20 It reduces the overall lifecycle cost of the vehicle and the rail. The applications listed above are only available if these applications are currently in use. It is used to show the application more clearly, and not intended to limit the scope of the current practice This is clarified with the understanding that the current practice is 25 After reading it, the current practices are evaluated by experts in the field. Various modifications made in equivalent forms, existing It is within the scope defined by the application's attached requirements.
