摘要： PURPOSE: To suppress a vibration generated when transmitted no power so as to eliminate effective shaft center displacement also when transmitted no power, in a gear type joint which performs high speed rotation to repeat transmitting power and not transmitting power. CONSTITUTION: By scissors gears 8, 9 mounted in external gears 3, 4 by a spring 10, a surface pressure is applied to act always between tooth surface of internal gears 5, 6 and the external gears 3, 4. Since force of eliminating a center deviation is applied to act always between the gears by the spring 10 of eliminating the center deviation, it is eliminated even when not transmitted power with action generated of eliminating the center deviation, so that a vibration due to unbalance mass can be prevented.

摘要： PROBLEM TO BE SOLVED: To prevent penetration of dirt and dust to a bearing guide due to output and input of outside air incurring in linkage with expansion and contraction of a bellows during operation of a pendulum, to provide an increased life for the bearing guide, and to improve reliability. SOLUTION: No air hole communicated with outside air is formed in a bellows 8 to cover a rail 7, and bellows 8 on the expansion side and the contraction side, making a pair, arranged on both sides of a bearing guide body 5 are intercommunicated through an air pipe 9. By moving internal air between the bellows 8 intercommunicated through the air pipe 9, penetration of outside air is prevented from occurring and a trouble, such as wear of the bearing guide by a contamination material contained in outside air, is prevented from occurring.

摘要： PROBLEM TO BE SOLVED: To provide an axle box supporting device for a railroad vehicle, making compatible riding comfort in a vertical direction and riding comfort in a roll direction, by securing roll support rigidity without setting vertical rigidity of an axle spring to be high, in an inboard type truck reduced in size and weight by narrowing a right and left space of the axle spring. SOLUTION: Axle beams 2 and 2' constituting the axle box of the inboard type truck generate rotation displacement at an axle center by vertical displacement of the right and left axle springs 5 and 5'. The roll support rigidity is improved by providing an inter-axle box twisting member 7 for transmitting twisting load to the axle beams 2 and 2' between the right and left axle beams 2 and 2'. When twisting displacement is going to be generated due to different vertical displacement of the axle springs 5 and 5', the inter-axle box twisting member 7 generates reaction in relation to the twisting displacement, works in a direction to cancel the twisting displacement between truck frames 4 from the axle beams 2 and 2', and suppresses the rotation displacement of the axle box. Both the riding comfort in the vertical direction by the soft axle springs 5 and 5' and the riding comfort in the roll direction by the improved roll support rigidity are improved.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle capable of improving riding comfortability of a vehicle body by suppressing transmission of vibration such that the vehicle body does not sensitively react relative to a large irregularity amount from a track.
SOLUTION: The railway vehicle has a structure having the vehicle body 3 supported on a truck 4 by an air spring 2 or a vibration-proof rubber; and a left/right movement stopper rubber 8 arranged between the vehicle body and the truck, arranged so as to have a space between a central pin 9 projected to a lower part of the vehicle body and the truck and suppressing left/right movement. A left/right clearance of the central pin 9 and the left/right movement stopper rubber 8 is made variable and spring constant in a left/right direction of the air spring or the vibration-proof rubber is softened. Further, the left/right clearance of the central pin and the left/right movement stopper rubber is made variable according to the track state or speed information. Thereby, transmission of vibration from the truck to the vehicle body at linear traveling can be suppressed and vehicle gauge at curved line traveling and construction gauge are not further committed.

摘要： PROBLEM TO BE SOLVED: To provide a control method for a pendulum device for a railroad vehicle capable of suppressing the possibility of generating fretting wear on the contact line of a roller and a roller bearing caused by neutrally maintaining the vehicle body when pendular movement is not performed.
SOLUTION: When the targeted angle of inclination of the vehicle body is 0°(Step 1), it is verified that traveling time to the curve of a track for pendular control is sufficient, or a criteria value or more (Step 2). After the verification, a pendular beam control angle θ(t) is set (Step 3). This enables pendular movement to be performed during travelling on a straight line in addition to during passing a curve at high speed, thereby always changing the contact position between the roller and the roller bearing. Therefore, this prevents the fretting wear caused by a continuous contact between the roller and the roller bearing in the same position to increase the life of the roller bearing, while this prevents vibration in getting over the damage portion of the roller to improve riding comfort. Further, the vehicle body is neutrally maintained by compensating the pendulum angle of the pendular beam with the pendulum angle of a bolster spring (Step 4).

摘要翻译：要解决的问题：提供一种用于铁路车辆的摆锤装置的控制方法，该控制方法能够抑制当在摆动时中性地保持车身时由滚子和滚子轴承的接触线产生微动磨损的可能性不执行移动。解决方案：当车身的目标倾斜角度为0°（步骤1）时，验证了用于摆动控制的轨迹的行进时间是否足够，或者是准则值以上（步骤2 ）。验证后，设定摆动光束控制角θ（t）（步骤3）。这使得除了在高速通过曲线之前，在直线行驶期间执行摆动运动，从而总是改变辊和滚子轴承之间的接触位置。因此，能够防止由于滚子和滚子轴承在相同的位置上的连续接触造成的微动磨损，因此能够延长滚子轴承的使用寿命，同时防止了超过滚子损坏部位的振动，提高了乘坐舒适性。此外，通过利用摇枕弹簧的摆角度来补偿摆梁的摆角度（步骤4），车体被中立地保持。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a railway vehicle simplifying the structure of a vehicle body by dispersing transmission of load between a sub-frame 2 and the vehicle body 1 and capable of suppressing manufacturing cost in the railway vehicle using the sub-frame applied between a truck and a base frame and installed with a connector. SOLUTION: The truck 6 supports the sub-frame 2 through support rubbers 5, 5 and supports the vehicle body 1 through an air spring 3 above the support rubbers. The connector 10 is installed on the sub-frame 2. The neighborhood to the installation part supports the vehicle body through a support rubber 4. Rail direction load applied to the sub-frame 2 and tie direction load are shared by stopper rubbers 12, 13 and shock-absorption rubbers 8c, 8c installed between the air spring 3, the support rubber 4, left and right ends of the sub-frame and the base frame. Since a central pin is not used for connection of the sub-frame 2 and the vehicle body 1, the structure of the vehicle body 1 is simplified and enhancement of mounting accuracy and mounting workability are improved.

摘要： PURPOSE:To provide an axle beam type axle box suspension device for railway vehicles which is not prevented from moving between a truck frame and an axle box due to snow. CONSTITUTION:In an axle beam type axle box suspension device wherein a truck frame 2 is supported on a spring 3 mounted on the body of the axle box 1 mounted on one end of an axle, and a head of an axle beam arm 4, which is integrated with the body of the axle box 1 in a body, is mounted on the truck frame 2 through a rubber 5, an axle box suspension device for railway vehicles is constituted in such a way that the shape of the cross section of the axle beam arm 4 of the body of the axle box 1 has a projected shape at the center. By this constitution, even while a railway vehicle is running in the snow, snow falls down, becoming hard to lay on the top of the axle beam arm 4, and in the case where snow falls and freezes during the stop of the railway vehicle, while the vehicle is running, the axle beam arm 4 like a blade cuts and removes the frozen snow due to the vertical motion of the axle box. Therefore, this constitution avoid the axle box suspension device from being prevented from moving between the truck frame and axle box.
