    摘要： A loss-prevention system includes a securing element securing components of a vehicle or rail vehicle and having a first portion and first and second lugs. The first portion is an elongate plate extending in a first plane. A first through-passage opening is disposed in the first portion. The first through-passage opening accommodates at least part of a first releasable connection for fastening the securing element on a first component. The first portion has a long side. The first and second lugs are disposed on the long side of the first portion, or opposite one another, and project from the first plane onto a common side of the first portion. The first lug is configured to rest on the upper side of the first component. The second lug is configured to support a second component on its underside and to secure the same against falling off.

    摘要： An abnormality detection method for a vehicle body tilt control device makes it possible to determine which air spring has an air supply/exhaust abnormality. A model creation step prepares a state estimation model for each of the front and rear vehicle halves into which a vehicle is divided, and an abnormality detection step applies a state estimation technique to the state estimation model to detect which one of the air springs has an air supply/exhaust abnormality. When flow rate command values for air supplied to/exhausted from the air springs included in each vehicle half are input, each of the input flow rate command values for air supplied to/exhausted from the air springs is multiplied by a virtual gain and the results are averaged. Based on the averages, the average of the heights of the air springs is output, where each virtual gain is included as a state variable.

    摘要： A suspension system for a rail car has at least two undercarriage members and at least one equalizer bar removably and pivotally secured to and between the two undercarriage members. A spherical bearing has an outer member that surrounds an inner member. The outer member is removably secured to one of the undercarriage members. The inner member is removably secured to the equalizer bar. The outer member defines at least one outer member section having an arcuate interior surface and the inner member defines at least one inner member section having an arcuate exterior surface. A low friction liner is disposed on at least one of the arcuate interior surface or the arcuate exterior surface.

    摘要： Disclosed is a telescopic type collision energy absorption device for a rail vehicle, which includes two sets of mechanisms functioned individually. The two sets of mechanisms are mounted respectively on either side of end portion of the vehicle. Each set of the mechanism includes an anti-climber, an energy absorption circular tube, pull rings, cutters, cutter fixing blocks, a mounting base, a cutter base, a guide cartridge, a double-acting type air cylinder, a base, bolts, torsional springs, pins, locating slots, a double-acting type solenoid valve, a controller and air storage tank. When the energy absorption device is in a non-operating state, the double-acting type air cylinder is in a state of tension where it pulls the energy absorption circular tube in such a way that the energy absorption circular tube is retracted into the interior of the guide cartridge, the cutters are pressed against the outer wall of the energy absorption circular tube. Before a collision of the vehicle, the double-acting type air cylinder under the effect of the high-pressure air pushes the second tube in such a way that the second tube is ejected outwards, the cutters are pressed against the locating slots of the energy absorption circular tube under the effect of spring force. The cutters cut the energy absorption structure and absorb the energy when the energy absorption circular tube is subjected to an external force and retracts towards the interior of the guide cartridge.

    摘要： An enclosure (10) has an inner space in which a rectangular parallelepiped shaped device unit (6) is storable, and has a side surface with an opening (20) for insertion of the device unit (6). A mounting frame (11) is a flat plate facing the opening (20) and disposed in the enclosure (10) on the opposite side of the enclosure (10) with respect in the opening (20). A guide unit includes a slide rail (12) extending from the mounting frame to the opening, and guides the device unit (6) between the opening (20) and the mounting frame (11) in a state in which the guide unit holds the device unit (6) in the Y-axis direction.
