Automatic control of automobile transmission performance test stand

To realize automatic control of automobile transmission performance test stand, the automatic control technique of the lubricant temperature, the program-controlled automatic shifting of the transmission, the continuous adjusting of revolution speed and load, data-acquisition and data real-time processing were adopted. The lubricant temperature was controlled at the set temperature ±2 °C. The automatic shifting of the transmission is simple, reliable and accurate. The automatic adjusting of load and rotation speed is rapid and accurate, the torque divergence is ±1 N·m and the rotation speed divergence is ±5 r/min. Conclusion is drawn that the four kinds of techniques which are applied into the automobile transmission performance test stand.
