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： PROBLEM TO BE SOLVED: To improve the riding comfotablness in an easement curve, by inclining a car body at a relatively moderate angular speed. SOLUTION: A device furnishes a car body inclination control mechanism, and it is composed to incline the car body positively by the instruction from a controller of the mechanism. An object inclination at the circular curve found from the curve data in the section a vehicle runs, and the speed signal of a speed detector; and an object car body rolling angular speed to a horizontal surface from the inclination of the railway by a cant, and an easement curve passing forecast time at the inlet and the outlet; are calculated, and in the easement curve section at the inlet and the outlet, a value multiplying a proportional gain to the deflection with the detected value from a rolling angular speed detector is made as the inclination control output, and the car body is restored to an inclined or a horizontal condition.

摘要： PURPOSE: To stabilize the operation of a body inclining hydraulic cylinder and improve the durability thereof by simplifying a body support structure and alleviating a lateral force acting on the cylinder, upon the inclination of a body. CONSTITUTION: A body support beam 4 supported on a pair of right and left coil type bolster springs 3 and 3 is installed on a bolster-less carriage 1 having a body inclination control device. Also, the beam 4 is provided with a pair of right and left body inclining hydraulic cylinders 5 and 5, and a body 6 is supported thereon. Furthermore, the beam 4 and the body 6 are jointed to each other with a pair of right and left links 14 and 14 along a longitudinal direction. Also, a pair of right and left stopper devices 15 and 15 are laid between the beam 4 and the body 6 for restricting a transverse position with the cylinders 5 and 5 contracted.

摘要： PURPOSE:To allow stoppage at a predetermined station by applying brake forcibly when an actual speed exceeds a speed in a stop pattern under a state where a stop pattern is included in an operating pattern to be communicated between a unit mounted on a train and a plurality of ground units disposed in the vicinity of a rail. CONSTITUTION:A train number and a stop pattern signal are inputted to an input unit 4 in a unit (a) mounted on a train (x) and then they are transmitted through a transceiver 2 to ground units 10a-10d arranged along a rail. Signals received on the ground side are sequentially taken into a terminal unit (t) through relays 11a-11d and collated with stored data. The terminal unit (t) makes a decision whether a train requires stoppage or not based on train numbers taken in and delivers a stop pattern through the relays 11b-11d to a train (x) requiring stoppage. Speed in the stop pattern received by the train (x) is then campared with an actual speed and if the actual speed is higher, a controller 3 outputs a brake signal to apply brake forcibly. Consequently, the train (x) can be stopped accurately at a target point.
