A bogie for a railway vehicle having at least one transverse member and at least two pairs of wheels supported by an axle box bearing

摘要

The present invention relates to a trolley for railway vehicles. The bogie includes at least one lateral member and at least two axle box support wheel pairs. The dolly is characterized in particular by having a lightweight design and by being able to be manufactured at low cost. The wheel-pair axle box is hinge-connected to the lateral member via two axle box bars, so that the axle box bar, the axle box, and the lateral member are configured in an H shape. The lateral member has at least two torsion bars provided so as to be parallel to the wheel-to-axle, and the torsion bar is firmly connected to the lateral member. Further, the torsion bar has an elastic bar, and an end region of the elastic bar that is not connected to the torsion bar is made to act on the axle box.
