为了提高矿用汽车驱动桥的出厂合格率,更好地对矿用汽车的驱动桥进行试验研究,研制了重型矿用汽车驱动桥试验台。该试验台结构简单、成本低;电动机由变频器控制,运转速度可随时调整。该试验台可进行驱动桥的磨合、检测等多种生产应用,同时还可以用于教学试验。本文详细阐述了该试验台的工作原理、结构组成及特点。 In order to improve the passing rate of mining truck drive axles and to carry out the test research on the drive axle of mining vehicles better, a test rig for driving axle of heavy mining vehicles was developed. The test stand has the advantages of simple structure and low cost; the motor is controlled by the frequency converter and the operating speed can be adjusted at any time. The test bench can drive the bridge running, testing and other production applications, but also can be used for teaching experiments. This paper elaborates the working principle, structure and characteristics of the test bench.
