Abstract (en)

[origin: DE19505338A1] In a guiding mechanism for radially controlling in a curve the wheelsets of rail vehicle bogies, both wheelsets are interconnected by two Z-shaped controlling means arranged each on one outer side of the bogie frame. The controlling means co-operate with the underframe, to which they are connected by joints. The controlling means (11, 11') are mounted each in a first vertical plane on both sides of the bogie frame (3) and at least one joint (21, 21') is arranged parallel to each controlling means in a second vertical plane offset towards the inside of the bogie frame (3). The wheelsets (5, 5') are radially adjusted in a curve exclusively on the basis of the torsion angle created between bogie (1) and underframe (4) when a curve is taken, regardless of the state of wear of the rails. The combination of controlling means (11, 11') mounted in a first vertical plane and of joints (21, 21') mounted in a second vertical plane allows the wheelsets to be controlled independently of the state of wear of the rails and strongly reduces the wear of wheel and rail flanges caused by guiding forces in the case of an automatic control.
