Title: BOGIE OF A RAIL VEHICLE WITH AT LEAST TWO WHEELSETS MOUNTED IN AXLEBOXES AND AT LEAST ONE TRANSVERSE MEMBER
Abstract:
The invention relates to bogies for railway vehicles with at least two wheelsets mounted in axleboxes and at least one transverse member. The bogies are in particular characterized in that they have a lightweight design and can be produced at low cost. The axleboxes of a wheelset are articulated to the transverse member via two axle levers so that the axle levers form an H shape with the axleboxes and the transverse member. The transverse member has at least two torsion bars arranged in parallel to the axles of the wheelsets, said torsion bars being firmly connected to the transverse member. The torsion bars have spring levers so that the end portion of the spring lever not connected to the torsion bar acts upon the axlebox.
