Title: Kenji Kurisu: Innovator in Automatic Transmission Technology
Introduction
Kenji Kurisu is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of automatic transmission technology, holding 2 patents that showcase his innovative approach to enhancing vehicle performance.
Latest Patents
One of his latest patents is a control system for automatic transmission using torque converter speed. This system includes a hydraulically controlled valve mechanism that connects and disconnects a supply of hydraulic pressure to frictional coupling elements. The mechanism allows for the automatic shifting of an automatic transmission into desired gears by locking and unlocking the frictional coupling elements. A time regulator is incorporated to manage the duration for which the valve mechanism is actuated, thereby adjusting the speed at which the frictional coupling element is locked based on the conversion efficiency of the torque converter.
Another significant patent by Kurisu is a hydraulic control system for controlling line pressure. This system is designed for a multi-speed transmission gear mechanism that includes an input shaft, an output shaft, and multiple friction coupling elements. The hydraulic control system selectively supplies hydraulic pressure to these elements, enabling the transmission gear mechanism to shift according to a predetermined shift pattern. The control system adjusts the target hydraulic pressure based on the type of shift and engine load, ensuring optimal performance during gear changes.
