Real comprehension of specific character of hydrostatic transmission is gained only from investigation into respective performances of hydraulic instruments and power flow originated from engine and transferred to load through hydraulic drive system; this flow is to be regarded as a power train system. This paper takes up our investigation into and experiment in distinctive feature on characteristic formula of hydraulic drive system gained from approximate characteristic formula of hydraulic instruments. Investigation and experiment have been performed on the characteristic of a power train system combined with a diesel engine. This investigation and experiment revealed the following: Impedance of hydrostatic transmission larger than that of a torque convertor is rather similar to characteristic of gear transmission. This hydrostatic transmission provides a continuously variable speed ratio not available for gear transmission. The above features could bring forth a better power controllability different from other transmissions.
