Bogie Wheelset Radial Mechanism with Structure of Adjustable Rigidity

Abstract

A bogie wheelset radial mechanism with a structure of adjustable rigidity, composing two secondary frames ( 21 ) which are pin-connected via two connecting rods ( 22 ) arranged in a crosswise manner. The connecting rods ( 22 ) are pin-connected to the secondary frames ( 21 ) with round pins ( 24 ). Joints between the round pins ( 24 ) and the connecting rods ( 22 ) and/or joints between the round pins and the secondary frames ( 21 ) are provided with replaceable elastic materials. The materials can be made into rings. End portions of the connecting rods ( 22 ) are embedded into mounting grooves ( 25 ) located in the secondary frames ( 21 ) and are connected to the same with the round pins ( 24 ).

1 . A bogie wheelset radial mechanism with a structure which is of adjustable rigidity, the wheelset radial mechanism ( 13 ) being composed of front and rear secondary frames ( 21 ) which are pin-connected via two connecting rods ( 22 ) arranged in a crosswise manner, wherein the connecting rods ( 22 ) are pin-connected to the secondary frames ( 21 ) via round pins ( 24 ), and joints between the round pins ( 24 ) and the connecting rods ( 22 ) and/or joints between the round pins and the secondary frames ( 21 ) are provided with replaceable elastic materials. 
     
     
         2 . The bogie wheelset radial mechanism with the structure which is of adjustable rigidity according to  claim 1 , wherein the joints between the round pins ( 24 ) and the connecting rods ( 22 ) and/or the joints between the round pins and the secondary frames ( 21 ) are provided with rings ( 23 ) made of the replaceable elastic materials. 
     
     
         3 . The bogie wheelset radial mechanism with the structure which is of adjustable rigidity according to  claim 1  or  2 , wherein end portions of the connecting rods ( 22 ) are embedded into mounting grooves ( 25 ) located in the secondary frames ( 21 ) and are pin-connected to same via the round pins ( 24 ). 
     
     
         4 . The bogie wheelset radial mechanism with the structure which is of adjustable rigidity according to  claim 1  or  2 , wherein the end portions of the connecting rods ( 22 ) are located on upper mounting planes ( 31 ) or lower mounting planes ( 32 ) of the secondary frames ( 21 ) and are pin-connected to same via the round pins ( 24 ).
