The document discusses a new generation of mechanical power variators (MPV) that can be used in a wide range of applications including agricultural machinery, construction equipment, vehicles, and industrial drives. It describes the working principle of MPV which uses variable eccentricity to provide stepless speed variation over a wide range. MPV offers advantages over other variator types such as high efficiency, broad speed control range, and reduced material usage. Technical specifications and test results for MPV integrated into tractor transmissions are also presented.
