Latest Patents

One of his latest patents involves an innovative automatic transmission design where the second and third clutches are axially aligned. This configuration allows the back side of the second clutch and the front side of the third clutch to oppose each other, while a first clutch is positioned radially inward of the second and third clutches. Additionally, the clutch drum is extended for common use by the second and third clutches. The second clutch is engaged and disengaged from the axial front side by a second piston of a second oil pressure actuator, while the third clutch is operated by a third piston of a third oil pressure actuator from the axial rear side. This compact arrangement allows for independent operation of the first through third clutches.

Another notable patent is for a hydraulic control apparatus for automatic transmission. This invention aims to prevent the formation of a neutral state in a change gear apparatus, ensuring that intended gear changes can be achieved even during a servo malfunction. The system utilizes hydraulic servos to engage and disengage multiple friction engagement elements, with a hydraulic pressure supply system that provides necessary hydraulic pressure to the servos. An auxiliary hydraulic pressure supply system is also included to maintain functionality in case of a malfunction.
