Embodiment Construction

[0013] refer to figure 1 , The contact bolster is a thin-walled multi-cavity casting with a complex structure, many parts with different wall thicknesses and large length dimensions. The entire box bears the load of the vehicle body, and the inner cavity is an additional air chamber for the air spring. The reinforcing ribs on the upper plane of the contact corbel and the cast transverse ribs and cast longitudinal ribs in the inner cavity jointly realize the strength guarantee of the main body of the contact corbel, and the reinforcing ribs in the middle are longer than the reinforcing ribs on both sides. The cavity can store gas, and all the cavities communicate with each other. At the same time, the side beams provide interfaces for secondary suspension components such as anti-snake shock absorbers and anti-roll torsion bars. The force of the anti-serpentine shock absorber and the force of the secondary vertical shock absorber. The side beams are respectively equipped with ...

Abstract

A high-speed train connecting sleeper beam comprises an anti-S-shaped damper base and an anti-lateral-twisting pull rod base. Square pins and round pin positioning guiding installing holes, all of which are connected with a train body are formed in end side beams. The high-speed train connecting sleeper beam is characterized in that the connecting sleeper beam is of an integral casting box structure, an integral cavity is formed in the middle of the connecting sleeper beam and serves as an additional air chamber for air springs, strengthening ribs are arranged on the upper plane, and the inner cavity of the connecting sleeper beam is composed of transverse casting bars and longitudinal casting bars. According to the connecting sleeper beam, the strength of the connecting sleeper beam is guaranteed, manufacturability and air tightness are good, the weight is low, and the strength is high. The simplicity of mounting and dismounting of a bogie and the train body is achieved, the monopoly from the foreign technology is broken, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a connecting corbel applied to high-speed EMUs. Background technique [0002] The contact bolster is the connecting part between the secondary suspension device of the bogie, the traction device and the car body, and bears and transmits various loads between the bogie and the car body. It is also used as an additional air chamber of the bogie equipped with an air spring system, which facilitates the repair and maintenance of the bogie and reduces the operating cost. [0003] At present, because there is no casting experience of similar products in China, the contact bolsters used in the bogies of high-speed EMUs are all cast aluminum alloy structures imported from abroad, and the cost is very high, which increases the production cost of the enterprise. In addition, the imported bolster is a trapezoidal shell, and the bolster needs to bear the load from the car body. The...
