The Selection of a Most Efficient Clutching Sequence Associated With Automatic Transmission Mechanisms

This paper presents a methodology for the identification of a most promising clutching sequence associated with an epicyclic-type automatic transmission mechanism. First, a methodology for the analysis of torque distribution on the links of an epicyclic gear mechanism is described. Then, the power loss relations associated with various clutching sequences of an epicyclic gear mechanism are derived. Finally, a procedure for the selection ofa most efficient clutching sequence associated with a transmission mechanism is developed.
