<p>A traction centre (10) for a railway bogie comprises a body mounted member (13) depending between fore and aft bogie mounted abutment members (14, 15) and a gap (16, 17) is provided between each abutment member (14, 15) and the body mounted member (13), so that during normal running i.e., when the vehicle is neither accelerating nor braking no longitudinal vibration will be transmitted to the body and the mass of the bogie will not couple with the natural body bending frequncy. Also the height of the traction centre is no longer critical since the bogie pitch movements cannot transmit any vibration to the body. A further advantage of the invention is that the provision of the gaps allows the bogie to rotate when the vehicle is rounding a curve without being restricted by the abutment members.</p> |
