Claims

[Scope of utility model registration request]

(1) A two-shaft drive system that simultaneously drives two front and rear axles perpendicular to the motor axis using a single electric motor, in which the direction of vehicle travel meets the axial direction, is characterized by the fact that a bevel gear-type small gear is directly attached to the electric motor shaft. - Two-shaft drive system for railway vehicles.

(2) The two-shaft drive device for a railway vehicle according to claim 1, wherein the tooth traces of the bevel gear system are twisted, and the twist directions of the gears are opposite to each other at both ends of the electric motor. −−“

(3) The scope of utility model registration claims as described in either paragraph 1 or 2, in which the bearing that supports the motor shaft also serves as a bearing for a small gear of a bevel gear system, and the Niredo bracket of the electric motor also serves as a gear box. Two-shaft motion device for railway vehicles.
