Description of the Invention: i A car body inclination device of a railway rolling 10 stock of one embodiment according to the present invention will be explained referring to form Fig. 1 to Fig. 6.
Fig.6 show only a left half part but omits a right half part. Wheel axles 2 having car wheels 1 are fixed to a bogie frame 4 through an axle spring member 3. A lower 15 face of a car body 8 is supported through an air spring member 5 which is mounted on the bogie frame 4. At the lower face of the car body 8 a center pin is provided and this center pin is connected to the bogie frame 4 through a traction device. To each of bogies 7, a following construction is installed.
A torsion bar 11 is installed rotatably freely to a vicinity of an upper portion of the bogie frame 4 along to a width direction (a rectangular direction of a running direction) of the bogie 7. Both ends of the torsion bar 11 are installed to the bogie frame 4 through bearing members 12. The bearing member 12 is fixed to the bogie frame 4 through rubber seats etc.. The bearing member 12 is a thrust bearing member. To both ends of the torsion bar 11, levers 13 and 13 which project in a radial direction are arranged. The torsion bar 11 and the lever 13 are connected through an involute gear shape mechanism. The levers 13 and 13 and the links 15 and 15 are connected through pins. Another end of the links 15 and 15 and a lower face of the brackets 17 and 17 are connected through pins.
10 A distance L1 from a connection point between the lever 13 at the one end of the torsion bar 11 and the link 15 to a connection point between the lever 13 at the another end of the torsion bar 11 and the link 15 is larger than a distance L2 between from a connection point between 15 the one link 15 and the bracket 17 of the car body 8 to a connection point between the other link 15 and the bracket o S 17 of the car body 8. In other words, the links 15 and are installed in an inner side of the car body 8. The link is installed incliningly with an angle against a horizontal face. The angle 3 is about from 50 degrees to agrees. Preferably, the angle 0 is 60 degrees.
When the car body 8 is inclined, the respective angles Dof the respective links 15 and 15 is varied.
According to this, the link 15 is formed to rotate the lever 13. The rotation direction of the link 15 and the rotation direction of the lever 13 are substantially orthogonal. For this reason, the link 15 is connected to the lever 13 through the rubber bush member or a spherical face bearing member. Further, the link 15 and the car body 8 are connected by a spherical face bearing member.
To the lower face of the car body 8, a stopper 21 is lifted down. To oppose to this stopper 21, stoppers 22 and 22 in a side of the bogie 7 are projected to an upper side portion from the bogie frame 4. The stopper 22 is arranged go.o•i in both sides (the both sides of the car body 8 in the 10 width direction). In commonly, between the stopper 21 and Sthe stoppers 22 and 22, a predetermined space is established.
Further, the stopper 21, and the stoppers 22 and 22 can be employed the members of the already provided. From 15 the connection member such as a center pin from the car body 8 is lifted down. A lower end of the connection member and the bogie frame 4 are connected with the link which is along to the running direction. This center pin can work as a role of the stopper 21.
An intersection point P of an extension line of the links 15 and 15 under the condition in which a car body 6 is not inclined is a center of the inclination of the car body 6. The extension line of the links 15 and 15 during the inclination time is not arranged to the intersection point P. The center of the car body 6 passes through the II 8 intersection point P. A gravity G of the car body 6 is arranged in the lower portion of the intersection point P.
With the above stated construction, in a case where the rolling stock runs a linear interval, it will be shown under the condition shown in Fig. 2. To the upper and lower movement of the bogie 7, the change of the inclination angle d of the links 15 and 15 is substantially the same. For this reason, the torsion bar 11 can rotate, .eeeei to the torsion bar 11 the twist is not generated.
0 Accordingly, the upper and lower movement of the bogie 7 can be permitted. In other words, the air spring 5 can be operated. As a result, the upper and lower displacement of the same phase at the both ends of the car body is not restricted, but a rolling displacement at the both ends of the car body is restricted.
The inclination motion of the car body during the curvature passage running time will be explained. To the curvature portion, a cant angle CO is provided. According to the cant angle CO, the curvature radius, and the running speed, the excess centrifugal acceleration are determined.
In this time, in accompany with the increase of the running speed in the curvature passage, the excess centrifugal acceleration increases also, to the passenger the acceleration in the left and right generates, the left and right riding feeling will be bad. The left and right I I I- II ordinary acceleration degree is 0.08 g as a rough standard value of a left and right normal acceleration.
When the rolling stock urns more than a balancing speed which is determined by the cant angle CO, the curvature radius and the running speed, as shown in Fig.3, according to the excess centrifugal acceleration, the car body 8 moves in the outer side of the curvature passage. A .o center position of the car body 8 is moved from a point A oeooo to a point The gravity of the car body moves from the 10 point G to a point The movement of the car body 8 is Sstopped by the contact to the stoppers 21 and 22.
According to the links 15 and 15 the car body 8 is inclined.
The inclination angle of the link 15 in the inner side becomes 61 and the inclination angle of the link 15 in the 15 outer side becomes p. The inclination angle of the car body 8 becomes 03. Since the car body 8 is inclined by the "".movement in the width direction, as a result the smooth inclination can be obtained.
According to the above stated construction, the upper and lower movement of the bogie 7 can be permitted, according to the excess centrifugal acceleration the inclination of the car body 8 can be permitted. Further, the constitution members are the torsion bar 11, the bearing members 12 and 12, the levers 13 and 13, and the links 15 and 15. It is unnecessary to provide an actuator for inclining the car body 8. For this reason, the construction of the inclination device can be formed easily, the construction can be formed with a light weight structure and a low cost structure. Further, it is possible to form the inclination of the car body in response to the curvature passage and further by corresponding the excess centrifugal acceleration since the inclination motion is carried out, accordingly the inclination device having the high fail-safe characteristic ooooo: can be attained.
10 When the excess centrifugal acceleration is fallen away, since the twist, etc., which are given to the left and right air springs 5 and 5 during the inclination time, are fallen away, the restoring force can be obtained, as a result the car body 8 can return smoothly from the o 15 inclination condition.
When the rolling stock runs the curvature passage, the leveling adjustment function for adjusting the height of the air springs 5 and 5 using the leveling adjustment valve for setting constant the height of the air springs and 5 is formed to stop.
An embodiment shown in Fig. 7 according to the present invention will be explained. In this figure, the same reference numerals shown in the above stated embodiment indicate the same members. The difference between this embodiment and the above stated embodiment is that actuators 30 and 30 are installed in a midway of the h ~~II links 15 and 15. Accordingly, the link 15 can be expanded and contracted freely. A control device is formed to retard a rod of the actuator 30 which is arranged an inner side of the curvature passage and the actuator 30 arranged in an outer side is projected. As a result, a length of the link 15 arranged in the inner side of the curvature passage becomes short and a length of the link 15 arranged in the outer side of the curvature passage becomes long.
oeooo: According this construction, using the inclination 10 target values executed under the basis of the curvature ee. Sinformation which are stored in advance (the curvature radius, the cant angle CO, etc.) and the running speed, the left and right displacement between the bogie 7 and the car body 8 or an actual measured left and right vibration S 15 acceleration which is installed to the car body floor face and the bogie frame 4 and the inclination angle, the eeoc* actuators 30 and 30 can be expanded and contracted.

According to the failure of the actuators 30 and and the control device, when the expansion and the contraction of the actuators 30 and 30 are not carried out, it presents the embodiment shown in Fig. i, as a result the car body 8 can be inclined according to the excess centrifugal acceleration.
ooeoo Using a detection means for detecting the expansion 10 amount and the contraction amount of the actuator 30, this detected value is feed-backed and is made to be a control amount, and then the inclination motion can be carried out smoothly. Further, as the actuator 30, a motor and a ball screw, and a mechanism of an air pressure system and a 0 o 15 hydraulic pressure system can be employed.
When the cant Co is less than an assumed running I. speed, the actuators 30 and 30 can be expanded and contracted in the reverse direction.

S" With the above stated construction, according to the control devices 40L and 40R for controlling the air spring the inclination action according to the link 15 etc. and the expansion and the contraction of the air spring 5 can 15 be operated at the same time, as a result the inclination motion of the car body 8 can be carried out smoothly.
•When according to a malfunction of the control devices 40L and 40R, a reverse inclination command is outputted and the car body 8 is made to inclined in a reverse direction, since the car body 8 is reversed to a natural inclination according to the link 15 etc., it is difficult to carry out the inclination in the reverse direction, as a result the fail-safe characteristic can be obtained easily.
When the expansion amount and the contraction amount or the inner pressure etc. of the air springs 5 and 5 are ls171 J_ detected, and the detected values are made to feed-back, then it is possible to carry out a good inclination operation.
Further, during the car body inclination time, when the leveling adjustment function of the air springs 5 and according to the leveling adjustment valve is made to stop, it is unnecessary to perform the leveling adjustment according to the supply and the discharge of the air to the o*o air springs 5 and 5, then it is possible to carry out the 9**9 10 good inclination motion.
When the cant Co is less than assumed running speed, the air springs 5 and 5 can be expanded and contracted in 9..
the reverse direction.
