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.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A railway rolling stock, characterized in that 
 a torsion bar is installed to a bogie or a car body along to a width direction of said bogie;    at both ends of said torsion bar a respective levers is provided;    between said car body and said bogie to which said torsion bar is not installed and an end portion of said respective lever are connected together with a link;    a first distance from a connection point between one of said link and said lever to a connection point between another link and said lever is larger than a second distance from a connection point between another end of said link and said car body or said bogie and a connection point between another link and said car body and said bogie; and    said first distance is formed in a side of said bogie and said second distance is formed in a side of said car body.    
     
     
         2 . A railway rolling stock according to  claim 1 , characterized in that 
 said torsion bar is installed to said bogie.    
     
     
         3 . A railway rolling stock according to  claim 1 , characterized in that 
 between said car body and said bogie, said car body provides a stopper for regulating a movement to said width direction against said bogie.    
     
     
         4 . A railway rolling stock according to  claim 1 , characterized in that 
 when the railway rolling stock runs on a curvature passage with more than a balancing speed, a drive device for inclining said car body is provided; and    in said drive device, a height from said bogie frame in an inner side of said curvature passage to said car body is lower than a height from said bogie in a linear passage to said car body, and a level from said bogie frame in an outer side of said curvature passage to said car body is formed high.    
     
     
         5 . A railway rolling stock according to  claim 4 , characterized in that 
 when the railway rolling stock runs on a curvature passage with less than a balancing speed;    in said drive device, said height from said bogie frame in said inner side of said curvature passage to said car body is higher than said height from said bogie in a linear passage to said car body, and said height from said bogie frame in said outer side of said curvature passage to said car body is formed low.    
     
     
         6 . A railway rolling stock according to  claim 4 , characterized in that 
 a control device for controlling said drive device performs to feed-back an expansion and contraction amount of said drive device.    
     
     
         7 . A railway rolling stock according to  claim 4 , characterized in that 
 between said bogie and said car body, a respective air springs is installed in said width direction; and    when the railway rolling stock runs with more than said balancing speed, a leveling adjustment function for said air springs according to a leveling adjustment valve is formed to stop.    
     
     
         8 . A railway rolling stock according to  claim 4 , characterized in that 
 as said drive device, an actuator for altering said length to said link is provided respectively; and    a length of said actuator which is positioned in said inner side of said curvature passage is formed short, and a length of said actuator which is positioned in said outer side of said curvature passage is formed long.    
     
     
         9 . A railway rolling stock according to  claim 4 , characterized in that 
 between said bogie and said car body, in said width direction, a respective air springs is installed;    said drive device is said air spring; and    the railway rolling stock runs with more than balancing speed on said curvature passage;    said drive device is said air spring; and    a control device is provided to form a height of said air spring which is positioned in said inner side of said curvature passage smaller than a height of said air spring which is positioned in said outer side of said curvature passage.    
     
     
         10 . A railway rolling stock according to  claim 4 , characterized in that 
 as said drive device, between said bogie and said car body, an actuator for moving said car is provided body in said width direction; and    when the railway rolling stock runs on said curvature passage with more than a balancing speed, said actuator moves said connection point between said actuator and said car body to an outer side of said curvature passage.    
     
     
         11 . A railway rolling stock according to  claim 1 , characterized in that 
 a center pin provided projecting in a lower portion of said car body and said bogie are connected through a link; and    in a width direction of said car body, to said bogie at both sides of said center pin, a stopper for contacting said center pin is installed.
