LATERAL OSCILLATIONS OF BOGIE BOLSTERS

It is imperative to break away from the adherence to general recipes regarding spring rates and swing link angles of inclination often regarded as a universal panacea against ailments generally diagnosed as "bad riding." Vertical leaf springs succeed only in increasing the lateral centering force thus reducing the effective length of the swing link arrangement and increasing its natural frequency, inadvertently acting as swing link spoilers. So far as design layouts are concerned detail components should be used along rational lines, each component being allowed to perform the basic function allotted to it. Thus swing links should be permitted to swing and dampers used to ensure damping. Excessive body amplitudes sometimes encountered with some designs can be controlled with the aid of lateral centering springs preferably with a non-linear characteristic and here suitably shaped rubber units can be of great help.
