摘要

The bogie truck has running wheels(20,21) with an outer casing in the form of a cone section, the running faces(18,19) of which are on the guide rail(17). The radius of the cone section of the outer casing of the running wheels correspond to the radius of the semi-cylindrical running faces of the guide rail. The outer casing of the running wheels has edge sections with a reduced radius. The running wheels are mounted with axial displacement.
