The invention relates to a twin-axle rail vehicle bogie with two extended wheel sets in bearings and a bogie frame on which the wheel sets are sprung. The load-bearing part of the bogie frame consists essentially of a bogie cross-member (1) to which are connected on a first bogie side a first link (2) for a first of the two wheel sets and on a second bogie side a second link (3) for the other, second wheel set, where both the first and the second link (2, 3) have a first free end which is pivoted about an axis on the bogie cross-member (1). According to the invention, the first and second links (2, 3) have a second free end linked to a main suspension system (17), where the wheel set bearing (21) concerned is fitted at a point between the first and second free ends and both links (2, 3) have an upper shank (47) ending at the second free end and running substantially vertically, and the main suspension system (17) is arranged in such a way that it exerts horizontally acting spring forces on the second free end.
