Axlebox fork crossbar

Abstract

The subject of the application is a fork axle lock yoke designed for a three-axle "37TN" railway bogie, applicable to six-axle freight wagons, for securing the axle lock yoke, mounted to the bogie frame using bolts; however, to protect the bolted connections against other loads, e.g., bending loads, shear loads, a grooved connection is used between the bogie frame and the axle lock yoke. It is characterized in that a plate (7) is located between the bogie frame and the axle lock yoke (1), permanently attached to the bogie frame, and in the contact zone between the plate (7) and the axle lock yoke (1), the plate (7) and the axle lock yoke (1) have a grooved surface (8).
