Embodiment 1

[0081] Example 1, such as figure 1 and Figure 17 As shown, the high-speed EMU bogie mainly includes a frame 10, a wheel set running device 20, a primary suspension device 30, a secondary suspension device 40, a driving motor 26, a traction device 50, and a foundation braking device 60. in,

[0082] A foundation braking device 60 is installed and fixed on the outer side of the frame 10, which includes a pair of side beams 11 and a pair of cross beams 12 connected to each other;

[0083] The side beam composition 11 has a hollow box structure, including a pair of upper and lower cover plates 111 and a pair of side webs 112 formed by welding; A pair of welded hollow steel pipes 121; a pair of air spring support beams 13 are welded and installed on both ends of the steel pipes 121 and outside the side webs 112, and the air spring support beams 13 have a hollow box structure. The beam composition 12, at least one longitudinal auxiliary beam 122 is welded between a pair of steel...

Abstract

The invention discloses a bogie of a high-speed motor train unit. By adopting a brand-new bogie structure and a hanging connection and traction mode, overall lightweight design is realized, the unsprung weight of the bogie is reduced, and the hanging parameter between the bogie and a body is optimized. On the basis that the high-speed running speed is met, stability when the bogie passes through a big corner and good traction and braking performance are expected. The bogie comprises a framework, two groups of wheel set travelling devices, a linear motor, a first hanging device, a second hanging device, a traction device and a foundation brake device. The framework comprises a pair of side beam assemblies and a pair of cross beam assemblies which are connected with each other; each side beam assembly has a hollow box body structure, and comprises a pair of upper and lower cover plates and a pair of lateral web plates which are welded; each cross beam assembly comprises a pair of hollow steel pipes penetrating the lateral web plates and welded with the lateral web plates; and a pair of air spring supporting beams is welded at two ends of a steel pipe and outside the lateral web plates.

Description

technical field [0001] The invention relates to an improvement of the overall structure of a bogie suitable for high-speed rail vehicles, and belongs to the field of machinery manufacturing. Background technique [0002] With the speed increase of the existing trunk line railways and the vigorous development of urban rail transit in China, higher design requirements are put forward for the bogie structure and performance in order to meet the high-speed operation of rail vehicles. [0003] The bogie frame in the prior art usually adopts a strengthened structure, and each component is connected to the suspended equipment with a relatively complicated structure. The disadvantage is that the weight is relatively large, and the space occupied by the external installation and load-bearing components is large, which is not conducive to steering. The lightweight design of the rack itself and the improvement of vehicle speed. [0004] At present, the driving speed of the new generat...
