摘要： PROBLEM TO BE SOLVED: To reduce the maximum lateral pressure of outer track wheels of a two axle truck for a railroad vehicle when passing a curve line and to prevent deterioration in safety of inner track wheels rather than a conventional truck.SOLUTION: The single axle steering truck steers only one of a front side wheel axle in a traveling direction and a rear side wheel axle in the traveling direction of the two axle truck. When passing the curve line, the incremental modulus of the steering amount with respect to the theoretical steering amount when the steering amount is 100% which is represented by β/{sin(a sin α/L)}×100, wherein β denotes the steering angle of the wheel axle, a denotes an axle distance, α denotes a boggy angle (a relative angle of the truck and a vehicle body at the curve line), L denotes a distance between the centers of the trucks, is adjusted within a range of not less than -10% to not more than 44%. In the single axle steering truck for the railroad vehicle for steering only one of the front axle and the rear axle, the lateral pressure acting on the outer track wheels is reduced when traveling on the curve line so as to avoid occurrence of derailment of the inner track wheels, thus, improving safety when passing the curve line.

摘要： PROBLEM TO BE SOLVED: To provide a method of accurately measuring a tangential force interacting between a wheel and a rail without providing a new strain gage bridge for tangential force measurement.
SOLUTION: This invention provides a method of measuring a tangential force which interacts between a rail and a railway vehicle wheel by using a PQ wheel set. This method measures a strain of a running wheel by a wheel load measuring strain gage for detecting wheel's radial strains. A relationship of tangential forces and strains read by strain gages for measurement of tangential forces is pre-determined by comparing a strain at each strain gage position when only a wheel load is working, and a strain at each strain gage position when only a tangential force is working. The tangential force working on a running PQ wheel set is obtained from these strains and the predetermined relationship. While a railway vehicle is running, this method can actually measure tangential forces required to improve the curve running, high-speed running, and acceleration/deceleration performances from the output of existing strain gages for wheel load measurement without increasing the number of test points.

摘要： PROBLEM TO BE SOLVED: To keep the airtightness of two auxiliary air chambers without carrying out plug welding.
SOLUTION: The truck for the railroad vehicle uses a bolster 1 or a truck frame as the auxiliary chambers 3a, 3b of two air springs 2a, 2b. For example, the two auxiliary chambers 3a, 3b in the bolster 1 is formed by dividing the inside of the bolster 1 in a vertical direction. A differential pressure valve 5 directly connecting the two auxiliary chambers 3a, 3b is provided on the bolster. Without carrying out plug welding requiring high welding skill, the airtightness of the auxiliary air chambers can be kept, so that a welding execution property can be greatly improved. Since a joint portion does not exist at a part on which a load is applied most, high strength can be obtained. Since a deep drawing press mold is not required, the truck can be inexpensively manufactured. Furthermore, when the differential pressure valve directly connecting the two auxiliary air chambers is provided on the bolster or the truck frame, it is not necessary to install piping for the differential pressure valve.
