Abstract

A new hybrid transaxle for 2.0L class vehicle (P711) was developed based on the Toyota New Global Architecture (TNGA) design philosophy. High performances and development efficiency were both realized by using main parts of P710, the larger sister model of P711 for 2.5L class vehicle, commonly and optimizing. A differential case friction part with a drive shaft inboard joint was one of the parts that required optimal design according to vehicle specification. For more efficient development, good design condition to ensure reliability was needed to be clarified quantitatively in this part. It was clarified by experimental analysis that moment force and clearance were sensitive design factors to temperature increase at a differential case friction part. The good design condition was clarified by the test to grasp the limit of reliability. Based on the good design condition, design of a differential case was streamlined, and it was possible to contribute to more efficient development.
