A bogie for a railway vehicle includes a frame, which has a first side beam and a second side beam extending along a longitudinal axis of the bogie and spaced apart from each other. A secondary suspension system is located on the frame and includes a first suspension assembly, which includes a first air spring and a first auxiliary spring positioned at the first side beam. The first air spring is positioned below and is arranged to be pressurized for supporting the body of the railway vehicle above the frame. The first auxiliary spring is fixed to an upper side of the first side beam underneath and spaced apart from the first air spring. The first suspension assembly further includes a first force-transmission mechanism configured to transmit forces exerted by the body on the first air spring to the frame via the first auxiliary spring.
