摘要:
A three piece railway freight truck is comprised of two laterally spaced side frames between which a bolster extends. Suspension load springs support the bolster, and control springs support friction shoes. Both variations of friction shoes have gaps that will allow lateral movement of the friction shoes across the bolster or the friction shoes across the side frame. The lateral movement is accomplished by having a low friction material pad between the bolster and the friction shoe or a low friction material pad between the friction shoe and a wear plate that bears on the side frame. The low friction material with low siding resistance allows lateral displacement energy to be dissipated over the lateral decoupling clearance.
