Embodiment Construction

[0027] Such as Figure 1-11 As shown, a locomotive, a motor vehicle bogie test device, including a loading unit 1, a track wheel set unit 2 that cooperates with the loading unit 1, a running unit 3 on the platform, a reaction force frame device 4, and a driving unit for driving the loading unit. 1 electric drive and control system. The loading unit 1 includes a dummy car body 11 and a test bogie set 12 and a test bogie set 13 arranged under the dummy car body 11. The dummy car body 11 is provided with counterweights for simulating the real axle of the bogie. Heavy. The tested bogie set 12 includes at least one bogie, and the accompanying test bogie set 13 includes at least one bogie. The bogie movement direction of the tested bogie set 12 is the same as that of the accompanying test bogie set 13. The speed of the bogies is the same, but the forces are different, and the two load each other through the way of dragging each other. The bogie cooperates with the track wheel set...

Abstract

The invention discloses a locomotive and bullet train bogie test device which comprises a loading unit, a rail wheel set unit used for being matched with the loading unit, an upper platform walking unit, a counter-force frame device and an electric transmission and control system used for driving the loading unit. The loading unit comprises a fake vehicle body, a tested bogie group and an accompanying bogie group, the tested bogie group and the accompanying bogie group are arranged below the fake vehicle body, two ends of the fake vehicle body are connected with the reaction frame device, the tested bogie group comprises at least one bogie, and the accompanying bogie group comprises at least one bogie. The tested bogie group and the accompanying bogie group are mutually loaded in an opposite dragging manner. The multi-vehicle and multi-bogie test bed provided by the invention improves the sample size of one test, can be used for bogie performance test and delivery test, and can also be used for loading durability and high-speed running-in verification test of each part of the bogie.

Description

technical field [0001] The invention belongs to test equipment, in particular to a test device for a locomotive and a train bogie. Background technique [0002] In recent years, my country's high-power electric locomotives and high-speed rail have achieved rapid development. Compared with traditional railway locomotives, their safety and reliability are even more important due to the significant increase in axle load and operating speed. Various types of vehicle and bogie test benches have been put into use one after another. The test benches are mainly used for performance and factory tests of complete vehicles and bogies. However, due to the low frequency of use of the traditional test bench, the designed test sample size is small, the utilization rate of the test bench is low, and the reliability is poor, so it is difficult to meet the needs of large axle load and high-speed operation. Contents of the invention [0003] In view of the above problems, the present invent...
