STRUCTURAL AND KINEMATICAL ANALYSIS OF THE COMPLEX PLANETARY MECHANISMS USED AS AUTOMATIC TRANSMISSIONS

Abstract

It is considered the kinematic structure of a complex planetary mechanism, which operates by using three planetary units with cylindrical gearings, as automatic transmission on passenger cars. Knowing the kinematic conditions in all 4+1 gears, the paper deals with a method of synthesis of structural – topological and kinematical type by the calculation of the analytical relations of input–output transmission functions in each gear.
