Abstract
A twin-axle rail vehicle bogie with two extended wheel sets and bearings and a bogie frame on which the wheel sets are sprung. The load-bearing part of the bogie frame includes a bogie cross member to which are connected a first link for a first of the two wheel sets and a second link for the other. Both the first and second links have a first free end which is pivoted about an axis on the bogie cross-member. The first and second links have a second free end link to a main suspension system where the wheel set bearing is fitted at a point between the first and second free ends. Both links have an upper shank ending at the second free end and running substantially vertically, and the main suspension system is arranged in such a way that it exerts horizontally-acting spring forces on the second free end.
