Method for engine RPM and ratio of transmission selection by stepless hydrostatic torque division transmission entails adjusting engine RPM and ratio of transmission to achieve maximum transmission efficiency in drive train

摘要

The method for the engine RPM and ratio of transmission selection by a stepless hydrostatic torque division transmission entails adjusting the desired output RPM by a combination of engine RPM and ratio of transmission. The engine RPM and ratio of transmission are adjusted in such a way that during the operating of the drive train a maximum transmission efficiency can be achieved. The operating point of the transmission is located on the envelope of the optimum transmission efficiency.
