Side Beam of a Bogie Frame for a Railway Vehicle

Abstract

A side beam of a railway vehicle bogie frame in which two such side beams define respective lateral sides of the bogie frame in relation to a longitudinal direction of the railway vehicle and a crossbeam extends over a transverse direction of the railway vehicle to join the side beams, the bogie frame being configured to carry, in use, front and rear wheelsets. The side beam is formed of discrete structural members comprising an elongate centre plate which extends between first and second end portions thereof in the longitudinal direction between positions occupied, in use, by the wheelsets, a thickness direction of the centre plate being parallel to the transverse direction, and first and second suspension mounts configured for mounting wheelset suspension elements thereto. The first and second suspension mounts are cantilevered from respectively the first and second end portions of the centre plate such that each suspension mount extends upwardly and longitudinally away from a respective junction with its end portion of the centre plate to define a space below the suspension mount for joining the suspension elements to the respective wheelset. At the respective junction each suspension mount has a greater width in the transverse direction than the thickness of the centre plate such that the suspension mounts protrude outwardly in the transverse direction from the centre plate. The discrete structural members are joined together by respective bolt connections.
