Abstract

Water hydraulic fluid switching transmission (FST) has lower environmental load and lower energy loss in a valve for using only ON/OFF valves. In addition, FST can recover kinetic energy during the deceleration phase. This paper is concerned with experimental results of the FST system. First, it was shown from experimental results that the error rate during the constant phase was limited to 5 percent. Next, two performance indices were introduced to analyze the energy efficiency of water hydraulic FST. Then, it was shown that the recovered energy during the deceleration phase was more than 30 percent of the kinetic energy of a flywheel. Therefore, the validity of water hydraulic FST was confirmed.
