Problems solved by technology

[0002] With the continuous acceleration of passenger trains, aerodynamic resistance has become the main resistance of high-speed trains. Numerous exposed beams, external boxes and bogies, fueled by extremely rough roads at close range, produce extremely strong aerodynamic resistance. The extremely powerful turbulence generated during driving is not only a major hidden danger to safety, but also a great waste of power

Embodiment Construction

[0014] The bogie of the train belly of the present invention is provided with a streamlined bogie fairing 5 that includes most of the wheels on the bogie and the bogie, and the bogie fairing 5 is shuttle-shaped when viewed from above.

[0015] A flat-plate crossbeam fairing 3 is installed close to the belly crossbeam, and a shock-absorbing and noise-absorbing rubber pad 2 is provided in the gap formed between the crossbeam fairing 3 above the bogie and the carriage floor 1 on the top of the crossbeam.

[0016] Between bogie fairing 5 and belly crossbeam fairing 3, colloidal gas-blocking and muffler skirt 4 is arranged in a circumferential circle.

[0017] In the bogie fairing 5, a shock-absorbing and sound-absorbing layer 6 is arranged at the position where there is a large gap between the front and rear wheels and the wheels on both sides, and the shock-absorbing and sound-absorbing material is clamped in the layer.

[0018] It also includes a fairing of the external box, and...

Abstract

The invention provides a high-speed train abdomen rectifying device, which relates to high-speed train manufacturing technology. A bogie of the train abdomen is provided with a streamline bogie fairing which covers the bogie and most part of a wheel on the bogie; and the bogie fairing is overlooked as a fusiform shape. The train abdomen rectifying device can significantly reduce the pneumatic resistance at the train abdomen, raise the running safety of a train and also greatly reduce the energy consumption, and has great practical value.

Description

technical field [0001] The invention relates to a high-speed train manufacturing technology, in particular to its belly flow diversion and rectification device. Background technique [0002] With the continuous acceleration of passenger trains, aerodynamic resistance has become the main resistance of high-speed trains. Numerous exposed beams, external boxes and bogies, fueled by extremely rough roads at close range, produce extremely strong aerodynamic resistance. The extremely powerful turbulence generated during driving is not only a major hidden danger to safety, but also a great waste of power. Contents of the invention [0003] The purpose of the present invention is to provide a high-speed train belly straightening device which can greatly reduce the aerodynamic resistance of the high-speed train belly in view of the above-mentioned defects. [0004] The technical solution of the present invention is: the bogie of the train belly of the present invention is provided...
