With a portfolio boasting three patents, Ohhara's work primarily focuses on improving fluid coupling and clutch mechanisms, showcasing his expertise and dedication to advancing technology.

Latest Patents

Ohhara's latest patents include a groundbreaking fluid coupling mechanism and an advanced viscous fluid clutch. The fluid coupling features an operation plate that defines storage and working chambers within a housing. It incorporates a communicating hole for efficient fluid communication, a driven wheel positioned adjacent to the operation plate, and a torque-transfer part that allows the rotor's torque to be transmitted to the housing. Furthermore, it includes a valve mechanism that effectively opens and closes the communicating hole, and an auxiliary chamber in the driven wheel that transports working fluid to the torque-transfer part.

The viscous fluid clutch, on the other hand, comprises a housing rotatably mounted to a drive shaft and a clutch plate attached to this shaft. The design features a fluid shear space between these components, utilizing fluid medium in the shear space to create a shear-type fluid drive. This invention incorporates a reservoir, an operating chamber, and a pump outlet opening, along with a uniquely designed annular wall that defines an auxiliary reservoir in coordination with the clutch plate. Additionally, blades within the annular passage assist in moving viscous fluid into the operating chamber, enhancing the clutch's efficiency.
