    摘要: A bogie, comprising an articulated mechanism (1), and two side beams (2) which longitudinally extend and are transversely spaced apart, wherein two cross beams (3), which are longitudinally spaced apart, are connected between the two side beams (2); each cross beam (3) comprises a middle section and edge sections located on both sides of the middle section; longitudinal beams (4) are connected between ends, which are located on the same transverse side, of the two middle sections; the articulated mechanism (1) is installed on the two longitudinal beams (4); and at least part of the edge sections are gradually inclined inwards in a transverse direction away from the middle sections. A reduction in a wheelbase of the bogie, and the enhancement of the small-curve passing capacity are facilitated.

    摘要: A ground gauge-changing structure for a gauge-changing bogie includes a pair of support rails (10) provided in parallel and a pair of first guide rails (20), a pair of gauge-changing guide rails (30), and a pair of second guide rails (40) provided in sequence along interior sides of the pair of support rails (10); an unlocking section (50) is provided between each of the first guide rails (20) and each of the gauge-changing guide rails (30), and a locking section (60) is provided between each of the gauge-changing guide rails (30) and each of the second guide rails (40); an inner/exterior side of the unlocking section (50) and an inner/exterior side of the locking section (60) are respectively provided with a pushing and positioning device (70) which applies a lateral thrust to a gauge-changing wheelset (80) passing through the unlocking section (50) and the locking section (60). The lateral thrust is applied by the pushing and positioning device (70) to the gauge-changing wheelset (80), so that both sides of the gauge-changing wheelset (80) are slightly displaced relative to the guide rails on which the gauge-changing wheelset runs, so as to readjust the positional relation between the components matched with each other on the gauge-changing wheelset (80), and facilitate improvement of the positioning precision, and ensure smooth unlocking and locking of the gauge-changing wheelset.

    摘要: The present application provides an anti-side-rolling damping vehicle-end device and a rail vehicle. The anti-side-rolling damping vehicle-end device comprises: a pair of damping mechanisms, which are adapted to respectively being installed on a pair of end walls of a pair of connected vehicle bodies that are arranged opposite each other, the pair of damping mechanisms being arranged on two sides of the axis of the vehicle bodies in a lengthwise direction, respectively; and a connecting rod, wherein two ends of the connecting rod are hinged to the pair of damping mechanisms, respectively, and the length of the connecting rod is greater than a vertical movement displacement of any vehicle body, such that side-rolling movement and vertical movement of the vehicle body is decoupled. By means of the anti-side-rolling damping vehicle-end device, it can be ensured that the length of the connecting rod connected between a pair of vehicle bodies can be far greater than a vertical movement displacement of each vehicle body, such that the movement of the damping mechanisms can be limited by means of the connecting rod in different movement processes of the vehicle body, thereby at least achieving the decoupling between side-rolling movement and vertical movement of the vehicle body. Therefore, side-rolling vibration can be suppressed more reliably while vertical stability is not affected, and the running stability and the riding comfort of a rail vehicle are greatly improved.
