Title: Yoshiaki Tajima: Innovator in Hydraulic Power Transmission
Introduction
Yoshiaki Tajima is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the field of hydraulic power transmission, holding a total of 2 patents. His innovative designs focus on improving torque characteristics in vehicles, showcasing his expertise in mechanical engineering.
Latest Patents
Tajima's latest patents include a hydraulic power transmission joint that features a torque varying mechanism. This mechanism comprises an accommodation hole with a relief hole at its bottom, which receives a check ball. The design ensures that the flow passage area between the accommodation hole and the check ball increases linearly as the check ball displaces after the relief hole opens. This results in a consistent flow passage area, imposing a hysteresis characteristic on the switching point between high and low torque transmission based on vehicle velocity.
Another patent by Tajima involves a torque characteristic shifting mechanism located in an accommodation hole of a rotary valve. This mechanism allows for a multi-step change in torque characteristics as vehicle velocity increases. The distances are set to meet specific relationships that optimize the performance of the vehicle.
