Abstract

The invention relates to a train bogie rectifying device and relates to the technical field of train rectifying. The train bogie rectifying device comprises a dome track, dome wheels, a casing frame, an access door, a dome outer casing, a carriage vehicle bottom, a bogie side frame, a guide device, a guide shaft, a guide shaft rubber sleeve, a guide sleeve, a guide sleeve seat, a guide sleeve seat board and a bogie. The train bogie rectifying device is characterized in that the dome outer casing is in a box shape with an upper opening and a lower opening, the dome outer casing is covered outside the bogie, the dome wheels are installed on two sides of the front upper portion and the rear upper portion of the outside covered dome outer casing, the dome outer casing is connected with the dome track through the dome wheels, and the dome track is connected with the carriage vehicle bottom. According to the train bogie rectifying device, on the premise that movement performances of train operation are not changed, air resistance of train operation is reduced, energy consumption is reduced, or train operation speeds are increased; free rotation of the bogie and relative movement of the bogie and a wagon box in an upward and downward direction are guaranteed; radiating during braking is guaranteed; loads are not added to the bogie; and the train bogie rectifying device is convenient to maintain.

Description

technical field [0001] A train bogie rectification device relates to the technical field of train belly rectification. Background technique [0002] Modern trains are constantly developing towards high-speed comfort. The resistance of trains mainly comes from the frictional resistance of wheels and rails, and the hydrodynamic resistance of airflow to trains. In order to overcome the resistance of the air flow to the running train, there is a skirt connected under the train car, but there is no skirt around the bogie of the train. The skirt will hinder the rotation of the bogie. Chinese patent application: 200810195674.6 proposes a technical solution for high-speed train belly rectification, but the feasibility is poor due to insufficient disclosure. First, according to the technical feature of claim 2: "a flat-plate beam fairing is installed under the belly beam", which blocks the braking of the wheels on the bogie by the train braking device; second, according to claim 2 ...
