Abstract
The present invention relates to a self-steering device for a railway vehicle, which includes axles installed on a truck supporting a vehicle body of the railway vehicle, wheels, each of which is connected to the axle and has a wheel tread moving on a top surface of a rail and supporting a vertical load of the railway vehicle, and a wheel flange protruding from the wheel tread to prevent the railway vehicle from derailing and being in contact with a lateral surface of the rail during straight movement of the railway vehicle to form an interference section, and guide rollers, each of which is in rolling contact with a top surface edge or a lateral surface of the rail in front or to the rear of the wheel when the railway vehicle enters curved rails and supports a greater transverse load than the interference section. The guide rollers can be directly installed on the railway vehicle or at least one of the vehicle body, the truck, and the axle.
