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.

摘要： The invention relates to a railway vehicle comprising a car (14) and a bogie (16). The bogie (14) comprises a chassis (28) and a secondary suspension system (30). The secondary suspension system (30) comprises: a set (34) of springs; a jack (36) comprising two ends (44, 46); and a supply device (38) of the jack (36). The jack (36) is configured to go from a first so-called retracted configuration in which the jack (36) is only connected to the car (14) by the first end (44) to a second so-called deployed configuration in which the jack (36) is also connected to the chassis (18) by the second end (16).
The power supply device (38) is configured, in the deployed configuration, to supply the jack (36) so as to move the car (14) away from the chassis (28) or to keep the distance between the car (14) and the chassis (28) constant.

摘要： A vehicle body inclination controller includes an air spring, an air reservoir, valve devices, an acquisition section, and a determination section. The determination section compares, with a predetermined threshold, at least one of a value of a ratio between supply control information of a supply valve and exhaust control information of an exhaust valve in the same valve device among the valve devices, a value of a ratio between pieces of the supply control information of the supply valves of different valve devices among the valve devices, or a value of a ratio between pieces of the exhaust control information of the exhaust valves of different valve devices among the valve devices, and determines that a failure occurs in the same valve device or at least one of the different valve devices when the value of the ratio exceeds the predetermined threshold.
