Integrated side beam main body structure in bogie and preparation method thereof

Abstract

The invention relates to the technical field of bogies, in particular to an integrated side beam main body structure in a bogie and a preparation method thereof. The integrated side beam main body structure in the bogie specifically comprises two air spring mounting bases, a side beam and first prepreg, and connecting blocks are arranged on the side faces, close to each other, of the two air spring mounting bases; inserting blocks are arranged on the side faces, close to each other, of the two connecting blocks, the inserting blocks are sleeved with the two ends of the side beams correspondingly, the outer side walls of the connecting blocks and the outer side walls of the side beams are wrapped with the first prepreg, the first prepreg is cured and formed on the outer side walls of the connecting blocks and the outer side walls of the side beams, and therefore the connecting blocks and the side beams are connected, wherein the first prepreg plays a role in local reinforcement, the force transmission path is optimized, the load is dispersed, the phenomenon of local stress concentration at the butt joint is relieved, the connection performance is more reliable, and practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of bogies, in particular to a main body structure of an integrated side beam in a bogie and a preparation method thereof. Background technique [0002] As the speed of maglev trains increases, the requirements for the components in maglev trains are becoming more and more stringent. Due to the defects of materials and processing methods, the frame often has high self-weight, poor overall strength, complex processing methods, and poor connectivity between various parts, especially where there will be local stress concentration at the joints of various parts. It is easy to be damaged, which is not conducive to driving safety. [0003] In the prior art, the main components of the bogie are mostly made of aluminum with relatively light density, and the processing method is obtained by casting aluminum alloy structure or extruded aluminum, and the connection between various parts is fixed by rivets or bolts.

[0002] As the speed of maglev trains increases, the requirements for the components in maglev trains are becoming more and more stringent. Due to the defects of materials and processing methods, the frame often has high self-weight, poor overall strength, complex processing methods, and poor connectivity between various parts, especially where there will be local stress concentration at the joints of various parts. It is easy to be damaged, which is not conducive to driving safety

[0003] In the prior art, the main components of the bogie are mostly made of aluminum with relatively light density, and the processing method is obtained by casting aluminum alloy structure or extruded aluminum, and the connection between various parts is fixed by rivets or bolts. Although the overall weight reduction has been carried out, the processing method is complicated, the cost is high, and the structural strength of the connection is low, and the two parts are prone to loosening. For example, the Chinese utility model patent of application number CN201420337150.7 was issued in October 2014 A magnetic levitation vehicle and its bogie disclosed on the 29th. The main components of the bogie are obtained by extruding aluminum. Insert the bolts for connection, the force between the two is only transmitted by the bolts, it is easy to make the force transmission uneven, thus damaging the bolts and the connection
