1 The new L110 hybrid transmission was developed for use in front-engine, rear wheel drive (FR) vehicles with 3.5-liter engines. The project goals were to develop a compact, slim structure that could be installed on a platform with an FR layout, and to provide the power performance, high-speed performance, and quietness of a luxury car while maintaining the fuel economy performance of a hybrid. To accomplish this, a new gear train, motor, and other components were developed. The newly developed hybrid transmission also uses coordinated control between the shift mechanism and the motor to achieve acceleration performance without causing the driver to feel any shock from an abrupt change of speed. This paper describes the main structural elements of the transmission and various aspects of its performance.

Recently, the performance of automobiles and industrial machines has improved remarkably. Bearing performance requirements have also increased. One of the performance requirements for bearings is increased bearing life in contaminated lubrication which contains wear debris. The bearing failure modes in contaminated lubricant are peeling caused by debris, and/or surface-initiated flaking caused by dent. Bearing life is increased by optimizing the surface hardness and the amount of retained austenite. Based on these results, a new bearing was developed, which showed ten times longer life than conventional bearings in contaminated lubrication.
