Friction wedges design optimized for high moment of friction with warpage and low damping force.

摘要

A bogie or bogie of railway or road, provided with a damping system for a trolley of road wagon having a crosspiece (14), a pair of side racks (10, 12), a plurality of wedges friction cushioning relative movement between the crosspiece (14) and side racks (10, 12), and a lateral spring or spring supporting each friction wedge, each friction wedge a generally triangular shape in which is defined phi angle between a vertical friction surface (22) and a sloping friction surface (24), wherein the angle phi and the force P of each side frame defined by the equations: ** ** FORMULA
