Railway car and bogie of railway car

Abstract

The invention provides a railway car body that causes less noise and that can be manufactured easily. The railway car comprises a subframe 40 disposed below a floor of the car body with a clearance therebetween, and a bogie 30 disposed below the subframe 40 with a clearance therebetween, wherein car body 10 and subframe 40 are connected via a center pin 50 protruding downward from car body 10 , and subframe 40 and bogie 30 are connected via a second center pin 70 protruding upward from the bogie. The lower end of the second center pin 70 is connected to the bogie 30 via a coupling link 110.

 at least two said cushion rubbers, one disposed above the other; and    plates projecting horizontally from said center pin at portions above and below said ring-shaped cushion rubber, and a second plate disposed on said subframe or said car body that is in contact with said plate.    
   
   
       3 . The railway car according to  claim 1 , wherein 
 said cushion rubber is ring-shaped when seen from a perpendicular direction, wherein one ring-shaped cushion rubber is disposed on an upper portion of said center pin and the other cushion rubber is disposed on a bottom portion thereof;    a post having said center pin vertically passed therethrough is formed either to said subframe or a floor of said car body; and    said other cushion rubber is interposed at a connecting portion between said center pin and a lower end portion of said post.    
   
   
       4 . The railway car according to  claim 1 , wherein 
 said center pin is T-shaped when seen from a width direction of the car body;    both ends of a horizontal block of said T-shaped pin are each connected via a ring-shaped cushion rubber to said bogie or said subframe;    a tip of a perpendicular block of said T-shaped pin is connected via a cushion rubber to said subframe or said car body; and    said cushion rubber disposed at the tip of said perpendicular block has a perpendicular height greater than a horizontal outer diameter thereof.    
   
   
       5 . The railway car according to  claim 4 , wherein 
 said horizontal block of said T-shaped pin is positioned below said perpendicular block.    
   
   
       6 . The railway car according to  claim 4 , wherein 
 said horizontal block of said T-shaped pin is positioned above said perpendicular block.    
   
   
       7 . The railway car according to  claim 4 , wherein 
 said center pin passes vertically through a space formed between one center sill and another center sill of the bogie, and on both sides of said center pin are disposed second cushion rubbers between said center pin and said center sills in the width direction of said car body.    
   
   
       8 . A bogie of a railway car having a car body mounted on a bogie with a clearance therebetween or having a car body mounted on a subframe with a clearance therebetween and the subframe mounted on a bogie with a clearance therebetween, wherein 
 said bogie and said subframe or car body are connected via a center pin that is perpendicular to the car body; and    said center pin is disposed movably at least in the horizontal direction to the car body or the subframe via a ring-shaped cushion rubber.    
   
   
       9 . The bogie of a railway car according to  claim 8 , further comprising 
 at least two said cushion rubbers, one disposed above the other; and    plates projecting horizontally from said center pin at portions above and below said ring-shaped cushion rubber, and a second plate disposed on said subframe or said car body that is in contact with said plate.    
   
   
       10 . The bogie of a railway car according to  claim 8 , wherein 
 said cushion rubber is ring-shaped when seen from a perpendicular direction, wherein one ring-shaped cushion rubber is disposed on an upper portion of said center pin and the other cushion rubber is disposed on a bottom portion thereof;    a post having said center pin vertically passed therethrough is formed either to said subframe or a floor of said car body; and    said other cushion rubber is interposed at a connecting portion between said center pin and a lower end portion of said post.    
   
   
       11 . The bogie of a railway car according to  claim 8 , wherein 
 said center pin is T-shaped when seen from a width direction of the car body;    both ends of a horizontal block of said T-shaped pin are each connected via a ring-shaped cushion rubber to said bogie or said subframe;    a tip of a perpendicular block of said T-shaped pin is connected via a cushion rubber to said subframe or said car body; and    said cushion rubber disposed at the tip of said perpendicular block has a perpendicular height greater than a horizontal outer diameter thereof.    
   
   
       12 . The bogie of a railway car according to  claim 11 , wherein 
 said horizontal block of said T-shaped pin is positioned below said perpendicular block.    
   
   
       13 . The bogie of a railway car according to  claim 11 , wherein 
 said horizontal block of said T-shaped pin is positioned above said perpendicular block.    
   
   
       14 . The bogie of a railway car according to  claim 11 , wherein 
 said center pin passes vertically through a space formed between one center sill and another center sill of the bogie, and on both sides of said center pin are disposed second cushion rubbers between said center pin and said center sills in the width direction of said car body.    
   
   
       15 . A railway car comprising a car body mounted on a subframe with a clearance therebetween and the subframe mounted on a bogie with a clearance therebetween, wherein 
 a coupling device that links to a coupling device of an adjacent car is joined to said subframe; and    said subframe adjoins said car body via two air springs at one longitudinal end of said car body, and is connected to a floor of said car body via plural connecting pins at another longitudinal end side of said subframe.    
   
   
       16 . A bogie of a railway car comprising a car body mounted on a subframe with a clearance therebetween and the subframe mounted on the bogie with a clearance therebetween, wherein 
 a coupling device that links to a coupling device of an adjacent car is joined to said subframe; and    said subframe adjoins said car body via two air springs at one longitudinal end of said car body, and is connected to a floor of said car body via plural connecting pins at another longitudinal end side of said subframe.
