摘要： PROBLEM TO BE SOLVED: To provide a single shaft bogie for railway rolling stock dispersedly supporting a part of the weight of a shaft beam on a vehicle body on a spring and on a bogie frame beam between springs, capable of reducing load applied to a track and smoothly steering a wheel along a line, even in a steeply curved line having a minimum rotation radius of ≤30 m.
SOLUTION: Both sides of one end part of the bogie frame beam 11 provided with a side beam part 11a are connected to a bottom surface of the vehicle body 2 via a bogie frame beam pin 17 so that the other end side may be oscillated in the vertical direction. A bolster spring 21 is interposed between the vehicle body 2 and the bogie frame beam 11. A pair of left and right shaft beams 12 are arranged in almost parallel to the side beam part 11a on a lower side of the bogie frame beam 11. One end part of each shaft beam 11 is connected to end parts on the bogie frame beam pin 17 sides of the bogie frame beams 12 via a shaft beam pin 19 so that the other end side may be oscillated in the vertical direction. A shaft spring 24 is interposed between the bogie frame beam 11 and the shaft beam 12. A wheel 14 rotatably supported by each bearing is steerably mounted on each shaft beam 12 with a king pin 26 as a center via a knuckle 28.

摘要： PROBLEM TO BE SOLVED: To smoothly and stably travel a bogie on a curve traveling route by connecting a radius rod with a sub-frame mounted on a car body via a universal coupling and providing front and rear guide wheels at both ends of a guide arm turning integrally with axles arranged before and after the wheels. SOLUTION: Front and rear parts of a bogie are assembled with a lower surface of a car body frame through a sub-frame 10. Other ends of upper and lower radius rods 11 are connected with brackets 15a of axles through a pivotally attaching shaft and the same spherical coupling. As a result, the axles are supported by the radius rods 11 integrated with upper and lower parts so that the axle center part may be movable in upper, lower, left and right directions. On lower surfaces of the axles, left and right connecting parts extending in front and rear directions are provided, guide arms 3a, 3b are integrally provided on front and rear sides. At tips of the guide arms 3a, 3b, each of guide wheels 4a, 4b is provided. By making the guide wheels 4a, 4b abut on guide rails 2 by pre-load, backlash at the time of a straight traveling can be prevented.
