Claims

[Scope of utility model registration request]

(1) In a two-shaft drive system in which a single electric motor whose axis direction is in the vehicle traveling direction simultaneously drives two front and rear axles perpendicular to the motor axis via a gear system, the electric motor and the gear system are connected to a buffer means. A two-shaft drive device for a railway vehicle, characterized in that the two-shaft drive device is mounted on the axle via the axle.

(2) The buffer means is characterized in that an elastic body is arranged between an outer cylinder and an inner cylinder interposed between a bearing fitted to an axle on which the electric motor and gear device are mounted and the axle. A two-shaft drive device for a railway vehicle according to claim 1 of the utility model registration claim.

(3) Practical use characterized in that projections are formed radially on the inner peripheral surface of the outer cylinder and the outer peripheral surface of the inner cylinder so as to mesh with each other, and the elastic body is disposed between the projections. A two-shaft drive device for a railway vehicle according to claim 2 of the patent registration claim.

(4) Registration of a utility model characterized in that recesses are formed at a plurality of locations facing each other on the inner peripheral surface of the outer cylinder and the outer peripheral surface of the inner cylinder, and the elastic body is disposed in the opposing recesses. A two-shaft drive device for a railway vehicle according to claim 2.
