摘要： PURPOSE:To provide a body inclining controller of air spring-loaded rolling stock, enabling it to use an air spring being small in an effective diameter. CONSTITUTION:This body inclining controller is so constituted that an incined beam 4 is supported on an air spring 3 installed at both symmetrical sides of a truck 2, more than two pieces of layered elastic bodies 5 vertically installed with a through hole are installed in space between this inclined beam 4 and a car body 1, supporting this body, and both symmetrical air chambers of a double acting cylinder 6 attached to this body 1 are connected together through each air pipeline 16 interposed with each through hole of the layered elastic bodies 5 between respective symmetrical air springs 3, while a detection signal out of each height controller 8 installed in the symmetrical air pipelines 16 is inputted into a controller 10, and a control signal pertaining to a body inclination from this controller 10 is made so as to be inputted into a drive unit 7 of the double acting cylinder 6. Accordingly, the air spring 3 and a pneumatic spring being small in content volume are made usable so that space saving is thus promotable. In addition, the extent of mass between springs becomes lessened, whereby riding quality is well improvable.

摘要： PURPOSE:To provide a body inclining controller of rolling stock that preventes any stopper contact by way of performing the inclining control between a car body and a truck through an inclining spring installed separately from a body supporting spring. CONSTITUTION:This body inclining controller is made up of supporting an inclined beam 4 on a body inclining air spring or hydraulic spring 6 installed at both symmetrical sides on a truck frame 2, while setting up a symmetrical pair of body supporting air spring 3 in space between this inclined beam 4 and a car body 1, and installing both symmetrical stoppers limiting the extent of longitudinal direction relative displacement in an interval between the car body 1 and the inclined beam 4. Accordingly, even if running on a curved railroad track at more than the setting speed and thereby excess centrifugal force works on the car body, there is no stopper contact at all, so that such a fear that riding quality might be worsened will in no case occur there.

摘要： PROBLEM TO BE SOLVED: To prevent wrong correction for the running position of a rolling stock passing a curved roadway by correcting a difference between an intermediate point of points where the radius of a curve calculated from the relative rotational change due to a bogie of a truck between a car body and the truck is before and behind a certain threshold and the intermediate point of the appropriate curve in roadway data. SOLUTION: The point where the radius (r) of a curve calculated from the value of a displacement gauge is below a certain threshold r0 is taken as a curve penetrating point d1 . The point where the subsequently calculated radius (r) of a curve is above the certain threshold r0 is taken as a curve escape point d2 . The point obtained by d2 -d1 is taken as the intermediate point dm of a curve. The curve intermediate point Dm is obtained from the curve in the roadway data. The curve intermediate point Dm is calculated from the distances of four points of the appropriate curve in the roadway data, a beginning of inlet transition curve BTC, a beginning of circular curve BCC, an end of circular curve ECC, and an end of outlet transition curve ETC, a radius of a curve R and a threshold r0 . The values of d1 , d2 are collated with the roadway data and if a match occurs, Dm -dm is taken as a correction amount to correct the running position.

摘要： PURPOSE: To improve the travel stability of a car body in preventing a cylinder on one side from extending at the same time by opening a bypass circuit via a pilot check valve at the other side by means of high pressure in this main circuit whenever a cylinder on the other is extending. CONSTITUTION: With the body 1 of a train traveling on a curved line, for example, at the time of extending a cylinder 7a on one side, a servo solenoid valve 11a on one side is selected, and operating oil from a pump 10 is fed to the one side cylinder 7a via a main circuit 12a. Then a cylinder 7b on the other is contracted by another servo solenoid valve 11b, keeping another main circuit 12b in low pressure. Therefore a pilot check valve 15a on one side is kept closed intact as its pilot pressure is not raised, so the one side cylinder 7a extends, tilting the car body 1. At this time, a pilot check valve 15b on the other is opened by dint of high pressure in the one side main circuit 12a, through which the operating oil is set free to a tank 10 from a bypass circuit 14b.
