摘要： PURPOSE:To enhance the stability of travel, at a curved rail zone in a bolster-less type railway vehicle bogie by constructing the bogies such that, when they reach the curved rail zone of a railway, each of them is greatly moved in back-and-forth directions and moved outwardly from the curved rails by centrifugal force. CONSTITUTION:Longitudinal levers 16, which are vertically arranged at mutually opposite widthwise end positions, respectively, of sides of the underside of a vehicle body, each have its lower end portion pivotally attached to a holder arm 17 fixed to a side beam 1 of a bogie frame, the upper end portion of each longitudinal lever 16 being pivoted to one end of a horizontal link 18. The other end of this horizontal link 18 is pivoted to a lower end portion of a vertical link 19 having its upper end pivoted to the underside of the vehicle body 11. Two operation links 20, 21, which are pivoted at one end to shaft boxes 5 via elastic members respectively, are rotatably connected at the other end to the longitudinal lever 16 at positions spaced by the same distance b in opposite directions from a center of connection N between the longitudinal lever 16 and the holder arm 17. At this time, the ratio of (a) to (b) (a/b) is set so as to become equal to the ratio of a distance L between the bogie centers to a distance l between the wheel shafts (L/l).

摘要： PURPOSE:To quickly sense a failure in a pressure governor, from which a control takes place, and provide possibility of automatic replacement of pressure governor by furnishing a synchronous circuit leading wire in the wheel formation, and therewith connecting together the current feed terminals of unload solenoid valves furnished in respective air compressors. CONSTITUTION:Current feed terminals P-1, P-2 of unload solenoid valves 10-1, 10-2 are connected together through a synchronous circuit leading wire 2, and respective air compressors are driven synchronously. Pressure switches 80-1, 80-2 are put on when the pressure air in an air piping has become below a specified level which lies under the lower limit pressure(s) of pressure governors 40-1, 40-2 so that the current feed paths of contactors 30-1, 30-2 receiving power supply through the contacts A-1, A-2 of relays 20-1, 20-2 are connected with power shut-off coils L-1, L-2, and these are fed with current. Thereby the air compressors can be restituted quickly to the normal operation, and the train operation efficiency be enhanced.

摘要： PURPOSE:To early find out re-skid immediately after re-adhesion by a method wherein current speed data are inputted to a storage part and a skid control part, an average acceleration determined on the basis of the speed data stored till the previous time is inputted to the skid control part, and when wheels are restored to re-adhesion from skid, all the speed data are replaced by the maximum speed in the speed data. CONSTITUTION:Speed data V1 are determined by an arithmetic part 2 on the basis of a speed pulse obtained from the current speed of a vehicle and inputted to a speed pulse input part 1 and are inputted to a speed data storage part 3 and a skid control part 5. The speed data storage part 3 outputs speed data V2 to Vn obtained till the previous time, and an average acceleration computing part 4 computes an average acceleration alphabeta and inputs it to the skid control part 5. When it is detected that wheels are restored to re-adhesion from skid, all the speed data in the storage part 3 at this time are rewritten by the maximum speed Vmax determined by an arithmetic part 6. According to this constitution, re-skid immediately after the re-adhesion is found out early, braking is quickened and damages of the wheels and rails are prevented.

摘要： PROBLEM TO BE SOLVED: To accurately and readily determine the abrasion limit of a sliding plate installed in a pantograph of an electric car. SOLUTION: This white solid lubricant 5a for a pantograph of an electric car, having same surface as a sliding plate, and capable of imparting lubricating activities to both a sliding plate 3a and a trolley wire by sliding on the trolley wire has a groove part having nearly same depth as the abrasion limit size of the sliding plate formed in the back side and filled with a colored solid lubricant 6a so that the colored solid lubricant may be exposed to the sliding surface when the thickness of the sliding plate 3a reaches the abrasion limit.

摘要： PURPOSE:To achieve efficient operation of a train maintaining riding comfort of passengers by substituting a detection data into a formula for determining a relationship of a train speed, a train acceleration, an angular speed of a box body, an angle of inclination of a roadway and a displacement value of the box body to calculate a cant value of the rail road. CONSTITUTION:A detecting section 10 detects a speed V of a train running on a railroad as indicated by 30 while detecting accelerations alphaX-alphaZ as indicated by X30-Z30 in the directions of the respective axes of X, Y and Z (X-Z) orthogonal to one another fixed on the train. Moreover, the detecting section detects angular velocity omegaX-omegaZ about the axes and a vertical displacement as indicated by 32X-32Z and 34 at parts of box bodies of the train. Then, an arithmetic device 20 inputs detection data from the detecting section 10 and calculates a cant value nd a radius R of curvature represented by an angle phi of inclination of a line controlling an arithmetic program stored in an ROM memory 26 with a CPU 24 to be outputted to an external display or the like or to be stored into an RAM memory 28 temporarily.

摘要： PURPOSE:To reduce lateral pressure of a front shaft outer track side at the time of passing a curved railway by switching for control steering device supporting rigidity, which uses front and rear asymmetric rigidity supporting method, of a front shaft side and a rear shaft side separately. CONSTITUTION:Air springs 5 of a front shaft 3 side and air springs 6 of a rear shaft 4 side of a front truck 1 and a rear truck 2 are connected respectively by separate pipelines 7, 8, and they are connected to a main air reservoir 14 by a pipeline 15 through solenoid valves 9, 10. The solenoid valves 9, 10 are switched by a forward and backward switching relay 11. Supporting rigidity of the front shaft side and the rear shaft side are separately controlled. Consequently, a steering device is operated effectively by a simple control equipment in response to the condition of a track.
