High speed railway wagon bogie
The invention discloses a high speed railway wagon bogie which comprises a frame and a wheel set guide hanging device which is arranged below the fame. The wheel set guide hanging device comprises an axle assembly and a rotating arm assembly, the first end of the rotating arm assembly is arranged on a carriage axle of the axle assembly in a sleeved mode, the second end of the rotating arm assembly is connected with the frame, a primary spring is arranged between the first end and a side beam of the frame, and the primary spring comprises an outer ring spring and an inner ring spring which are embedded with each other. An ejection spring is further included and is arranged between the inner ring spring and the side beam, and the ejection spring has precompression amount in the process of empty dispatch. Thus, when a high speed railway wagon is in the working condition of empty dispatch, due to the fact that the ejection spring is arranged between the inner ring spring and the side beam of the frame and has the precompression amount, a restraint effect is achieved on the inner ring spring, vibration of the inner ring spring can be avoided, position offset or abrasion of the inner ring spring caused by vibration can be avoided, and therefore the operation performance of the high speed railway wagon in the working condition of empty dispatch and heavy vehicles can be improved. 1.
