Embodiment

[0031] Please refer to Figure 1~3 , this embodiment provides a new axle fatigue test bench 1000 . The axle fatigue test bench 1000 includes: a base 100, a track wheel 200, an experimental wheel set fixture 300, a first actuator 400 and a second actuator 500.

[0032] The track wheel 200 is rotatably arranged on the base 100 and is driven by the driver 700. The track wheel 200 has a matching part for carrying the tested wheel pair 800 and for cooperating with the tested wheel pair 800. The experimental wheel set fixture 300 is mounted on the base 100 and has a mounting portion for installing the tested wheel set 800.

[0033] The first actuator 400 is arranged vertically and above the experimental wheel set holder 300 for applying a vertical load to the tested wheel set 800 mounted on the experimental wheel set holder 300 . The second actuator 500 is arranged in the horizontal direction and is separately arranged on both sides of the experimental wheel set fixture 300, and t...

Abstract

The invention, which relates to the technical field of locomotive vehicle testing, provides a novel axle fatigue test bench comprising a base, a track wheel, an experimental wheel set fixation device,a first actuator, and second actuators. The track wheel is arranged at the base in a rotating manner and is driven by a driver. The track wheel has a cooperation part that is used for carrying a tested wheel set and cooperates with the tested wheel set. The experimental wheel set fixation device arranged on the base has a mounting portion for mounting the tested wheel set. The first actuator thatis disposed vertically and is arranged above the experimental wheel set fixation device is used for applying a vertical load on the tested wheel set installed at the experimental wheel set fixation device. The second actuators are disposed in a horizontal direction and are arranged at the two sides of the experimental wheel set fixation device respectively; and the second actuators are arranged in a direction perpendicular to the rotation axis line of the tested wheel set to apply the steering force on the tested wheel set. Therefore, the accuracy of load transferring is improved; the real load effect can be reflected accurately; and the fatigue test result becomes accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of testing railway locomotives, in particular to a novel axle fatigue test bench. Background technique [0002] The inventors of the present application have found through research that: the existing axle fatigue test bench restricts some degrees of freedom during the measurement process, so that the load transmission does not conform to the actual situation, and does not have the effect of reflecting the real load. [0003] In view of this, this application is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a novel axle fatigue test bench, which greatly improves the accuracy of load transmission, can more accurately reflect the real load effect, and the result of the fatigue test is more accurate and reliable. [0005] Embodiments of the present invention are achieved like this: [0006] A novel axle fatigue test bench includes: a base, a rail wheel, an ex...
