CA 2231189

In a bogie for rail vehicles with a frame (1), two sets of wheels (2) and a steering linkage (3) for radially adjusting the wheel sets (2) in track curves, there are springs (5) between the bogie frame (1) and the bearings (4) of the wheel sets (2). The steering linkage (3) is coupled to the wheel set bearings (4) beneath their horizontal central plane (M). In order by simple means to provide a largely non-wearing connection between the wheel sets (2) and the bogie frame (1) permitting the radial adjustment of the wheel sets (2) in track curves, the wheel set bearings (4) are guided longitudinally and transversely by a guide leaf (6) on the bogie frame (1) engaging above the horizontal central plane (M). Each guide leaf (6) is sprung and acts parallel to the springs (5).

L'invention concerne un bogie pour véhicules sur rails, comportant un châssis (1), deux paires de roues (2) et une timonerie de direction (3) pour le réglage radial des paires de roues (2) dans les voies en courbe. Entre le châssis de bogie (1) et les paliers (4) des paires de roues, sont disposés des ressorts (5). La timonerie de direction (3) est raccordée aux boîtes d'essieux (4) au-dessous du plan central (M) horizontal de ces dernières. Pour obtenir par de simples moyens une liaison entre les paires de roues (2) et le châssis de bogie (1), qui soit quasiment inusable et qui autorise le réglage radial des paires de roues (2) dans les voies en courbe, les boîtes d'essieux (4) sont respectivement guidées longitudinalement et transversalement sur le châssis de bogie (1) par un guide à lame (6) qui s'emboîte au-dessus du plan central horizontal (M). Chaque guide à lame (6) est élastique et agit parallèlement aux ressorts (5).
