Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicle detection, in particular to a rail vehicle bogie performance comprehensive detection device. Background Art

[0002] The rail transit vehicle bogie, also known as the running gear, is one of the most important components in the rail vehicle structure. It is located between the vehicle body frame and the rails. It is a running device that supports the vertical load of the vehicle body, generates and transmits traction and braking force, and guides the vehicle to run along the track. Each vehicle is equipped with a two-axle bogie at both ends. Whether its structure is reasonable will directly affect the vehicle's running quality, power performance and driving safety.

[0003] When measuring parameters, the rail vehicle bogie is generally fixed on the test bench by wheelset fixation or frame fixation. When using the wheelset fixation method, force is applied to the frame during the test to cause relative displacement between the frame and the bogie. However, a single test bench cannot test multiple types of bogies. When different types of bogies are tested, different test platforms need to be used to adapt to the detection wheelset. The test platforms of multiple types occupy a large space and have low utilization rates.

[0004] In addition, the existing test bench can only move horizontally when testing the rail vehicle bogie, resulting in a relatively single testing environment. Since rail vehicles have uphill and downhill environments, a single horizontal movement cannot test the performance of rail vehicle bogies under different slope conditions.

[0005] Therefore, the present application provides a comprehensive detection device for rail vehicle bogie performance to meet the needs. Utility Model Content

[0016] 1.

By flexibly adjusting the position of the rail, not only can the bogies of different models to be tested be positioned quickly and conveniently, but also the support and the rail can be pushed during the test to make the rail change and rub against the bogie to be tested, adjust the action force between the wheel and the rail, detect the stress and wear between the wheel and the rail, and thus detect the dynamic performance of the bogie;

[0017] 2. The testing platform can be movably connected to the support seat at the bottom through the fixed frame and the rotating shaft. During testing, it can be extended and retracted through the first electric telescopic rod on the bracket at the lower end of the support seat. The first electric telescopic rod can resist the bottom of the testing platform and push the testing platform upward, so that the testing platform can be rotated, so that the angle of the testing platform can be adjusted front and back, so that the rails and the vehicle bogie are at different slopes, and the performance of the vehicle bogie can be tested under different slope conditions, making the test more comprehensive.
