車輪双方の摩耗が大きくなるという欠点があった。The two wheel axles 9 are connected to an axle spring 7. It is supported parallel to the stand frame 6 by an axle box 8 and its support device (not shown). The vehicle body 1 rests on a pillow beam 4 via an air spring 2, and its position in the longitudinal direction is determined by a bolster anchor 3. The pillow beam 4 is connected to the center plate 1 of the truck frame 6 by the upper center plate 5.
0, and the relative rotation of the upper center plate 5 and lower center plate 10 allows the entire bogie frame 6 to steer when passing through a curve. (The steering wheel is cut using the frame ratio frame 6 while maintaining the parallelism of the two pairs of wheels @9. Therefore, the IJ
is not. ) In general, in conventional bogies, the support rigidity of the axle box in the longitudinal direction is often set high from the viewpoint of high-speed running performance, and the natural movement of the wheel axle as shown in Fig. 7 is achieved even when passing through a curve. The spring system is designed to suppress the
This had the disadvantage of increasing wear on both wheels.

る。An object of the present invention is to provide a bogie that can easily pass through curves by taking advantage of the natural steering action that occurs due to a one-diameter difference between the contact points of wheels and rails (see Figure 7) when passing through curves, thereby reducing lateral force. The objective is to reduce wear on both the rails and wheels.

圧が低くレール、車輪双方の摩耗の少ないことに特像が
ある。The first aspect of the present invention is that the bogie frame, which was conventionally integrated, is divided into two parts, and each can rotate independently at the center of the frame, allowing for natural steering. The special feature is that there is little wear on both wheels.
本発明の一実施例を第３図および第４図に示す。An embodiment of the invention is shown in FIGS. 3 and 4.
車体１は空気ばね２を介して枕はり４の上に載っており

および上下軸まわりの回転はしないようになっている。The vehicle body 1 rests on a pillow beam 4 via an air spring 2, and is positioned approximately rearward by the pillow beam 4 (!) with a bolster anchor 3, and although it can only move from side to side relative to the vehicle body 1, it cannot move forward or backward. Also, rotation around the vertical axis is prevented.

心ビンプンノユ１７が設けである。Therefore, when passing through a curve, as shown in Figure 7 (bl), due to the difference in diameter between the contact points of the outer and inner wheels, each wheel axle adjusts to the curve and does not impede the movement of the vehicle. Since each wheel axle 9 steers at an optimal angle relative to the vehicle body 1, the wheels 7 do not come into contact with the rail surface, reducing lateral pressure and reducing wear on both the wheels and the rails. The upper flat load applied from the pillow beam 4 is applied to the bogie frame 15.16 via the upper center plate 11.・b plate m plate 12.
7. The signal is transmitted to the wheel @9 via the axle box 8. Center beam/13 and truck frame 15.
16, the upper load and the rear load are transmitted between the bogie frames 15 and 16, and since the bogie frames 15 and 16 rotate independently around the vertical axes, a central bump 17 is provided to prevent wear and reduce sliding resistance. It is.

are each installed. In order to improve running stability at high speeds, the oil damper 21 and spring η provide appropriate damping and elasticity for one rotation of the center pin (vertical axis) of the bogie frame 19°. They are provided on both left and right sides between the frame 19 and the joint.

9. In order to not hinder the relative rotation with a long period of 20, but to suppress the relative rotation with a short period caused by the left-right vibration of the vehicle body while running in a straight line, a small deterioration force is applied to low-frequency vibrations and high-frequency vibrations are suppressed. It is designed to have a great mitigating power against vibrations.
