Transmission Study of Planetary Gear Mechanism Based on Matrix Theory

Abstract

According to the characteristic formula of planetary gear transmission, by studying the movement and torque transmission of planetary gear mechanism of Automatic Transmission, this paper presents a new method of transmission analysis by use of the matrix. The method established the mathematical model about the coupling form and shift constraint and torque transmission between the planetary lines based on matrix theory. It is generally applicable to the movement and torque calculation of complex planetary gear mechanism.
