[0033] Example
[0034] Please refer to Figure 1~2 , This embodiment provides a new type of axle fatigue test bench 1000. The axle fatigue test bench 1000 includes: a base 100, a base 200, a track wheel 210, a test wheel set holder 300, a first actuator 400, and a second actuator 500.
[0035] The track wheel 210 is rotatably disposed on the base 200 and is driven by the driver 150. The wheel surface of the track wheel 210 has a matching portion for carrying the measured wheel pair 600 and for matching with the measured wheel pair 600. The experimental wheel set holder 300 is erected above the base 100 and has an installation part for installing the tested wheel set 600.
[0036] The first actuator 400 is arranged in the vertical direction and above the experimental wheel set holder 300 for applying a vertical load to the measured wheel pair 600 installed on the experimental wheel set holder 300.
[0037] The base 200 is slidably disposed on the base 100, and the slidable direction...
