Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] see Figure 1-2 , an A1A axle bogie, including a bogie frame 4, two end shaft wheel pairs 5, an intermediate shaft wheel pair 10 and two driving devices 16, and the two driving devices 16 are respectively connected to the two end shaft wheel pairs 5 connected, the end shaft wheel pair 5 is a driving wheel pair, the intermediate shaft wheel pair 10 is a driven wheel pair, and the wheel diameter of the intermediate shaft wheel pair 10 is smaller than the wheel diameter of the end shaft wheel pair 5, preferably Ground, the end shaft wheel pair 5 adopts the end wheel 13 with a diameter of 1250 mm, and the intermediate shaft wheel pair 10 adopts an intermediate wheel 18 with a diameter of 920 mm; The sinking of the middle part of the beam can realize the sinking of the frame installation surface of the secondary spring 9 to meet the height requirements of ...

Abstract

The invention discloses an A1A axle type bogie. The A1A axle type bogie is characterized in that the A1A axle type bogie comprises a bogie structure, two end axle wheel pairs, a middle axle wheel pairand two driving devices. The two driving devices are connected with the two end axle wheel pairs correspondingly. The end axle wheel pairs are driving wheel pairs. The middle axle wheel pair is a driven wheel pair. The wheel diameter of the middle axle wheel pair is smaller than the wheel diameter of the end axle wheel pairs. According to the A1A axle bogie, the power axle weight of a passenger locomotive or a power concentrated motor train unit is smaller than or equal to 17 tons, the speed reaches the level of 200 km / h, and the length of the whole bogie is suitable for a traditional Bo-Bo type passenger locomotive.

Description

technical field [0001] The invention relates to the field of rail transit locomotive vehicle bogies, in particular to an A1A axle type bogie. Background technique [0002] my country's current railway policy stipulates that the axle load of vehicles operating on high-speed passenger dedicated lines must be less than or equal to 17 tons, but at present there is no locomotive or power-concentrated EMU power car with an axle load of less than 17 tons in the world. It is difficult for EMUs to run cross-lines on high-speed passenger dedicated lines and existing lines. Although the bogie technology for passenger locomotives with a speed of 200km / h is relatively mature at home and abroad, the axle loads of locomotives using these bogies are all greater than 18T, and the locomotives with existing bogie technology cannot achieve axle loads less than or equal to 17T. [0003] In order to solve the problem of excessively large axle load, some scholars at home and abroad have studie...
