BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel separation jig for a railway vehicle, and more particularly, to a wheel separation jig for a railway vehicle that can perform a quick and easy separation operation even when a separation operation of wheels is difficult due to a space shortage between the driving gear and wheels.

Generally, a pair of wheels are installed on both sides of a railway car before and after the railway car, and the wheel is subjected to a replacement operation when it is worn out or the weight (tonnage) is less than the required weight.

On the other hand, since the wheel is very important compared to other parts, it is a main cause of derailment induction and braking failure to use for a long period of time when uneven wear occurs or underweight.

Accordingly, a separating jig capable of replacing and separating the wheels to prevent derailment and defective braking caused by uneven wear or under-weighted wheels for a long period of time is required, and a wheel separating jig is proposed in accordance therewith .

However, when a driving gear is installed on one side of a wheel, the conventional wheel-separating jig for a railway vehicle can not mount the jig because there is no space between the wheel and the driving gear, Since the mounted shaft must be pinched and separated, not only the operation time is long, but also the wheel shaft is deformed.
