Development and Test of HMPT-500

Abstract

An HMPT-500 hydromechanical power train was designed for the requirements of a MICV-type vehicle. To satisfy performance and design specifications, an entirely new design concept using only two pairs of hydraulic elements instead of three was developed. This power train differed from previous General Electric units in that reverse and low forward speeds use hydrostatic drive with the more efficient hydromechanical drive being employed for higher forward speed. The control system for the transmission was based almost entirely on previous transmission controller design concepts and used existing component configurations in a large number of places. Only in those instances where space considerations became overriding were new (but similar) components used.
