Embodiment Construction

[0025] A car body inclination device of a railway rolling 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 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.

[0026] 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 throug...

Abstract

A car body 8 is supported on a bogie frame 4 through an air spring 5. Along to a width direction of the car body 8, to the bogie frame 4 a torsion bar 11 is provided. At both ends of the torsion bar 11, links 15 and 15 for inclining to direct for an inner side of the car body 8 through levers 13 and 13 are provided. Accordingly, a rolling displacement of the both ends of the car body is restricted and an upper and lower displacement in the same phase is not restricted. According to an occurrence of an excess centrifugal acceleration which acts on the car body 8, a car body inclination according to a link mechanism can be operated. For this reason, a light weight structure and a low cost structure can be attained. An inclination device having a light weight structure, a left and right riding good feeling in the passenger in a car, and a high fail-safe characteristic can be obtained. An inclination device having a light weight structure, a left and right riding good feeling in the passenger in a car, and a high fail-safe characteristic can be obtained.

Description

[0001] 1. Technical Field[0002] The present invention relates to a railway rolling stock and relates to a device for inclining a car body to improve a riding feeling during a curvature passage running time in the railway rolling stock.[0003] 2. Prior Art[0004] As a car body inclination device in a railway rolling stock, as shown in Japanese application patent laid-open publication No. Hei 6-56034, the car body inclination device is one in which a torsion bar is used. The car body inclination device comprises a first torsion bar which is provided in a left and right direction of the car body, a second torsion bar which is provided respectively on both ends thereof, an actuator for connecting respectively each end of the first torsion bar and one end of the second torsion bar, and a rod for connecting another end of the second torsion and the car body. The actuator is installed in a front and rear direction of the car body. By the expanding and contracting of the actuator, and the rod...
