Abstract
An articulated bogie for railroad vehicles, comprising lateral equalizing bars connecting the axle boxes, and connected to each other by a primary cross member. The lateral equalizing bars (3) are connected directly to the axle boxes (2) without the use of suspension. The primary cross member (6) is resiliently carried by vertical supports on each equalizing bar (3), the supporting arrangement being provided at each end of the cross member, the two points (7) of which are spaced and equidistant from the center. A secondary load-bearing cross member (11) is carried on the primary cross member (6) by a secondary suspension system (10).
