Latest Patents
One of Katou's latest patents involves a sophisticated automatic transmission system. This invention features a duplex planetary gear set where a first element is selectively coupled to an input shaft via a third clutch or is fixed via a first brake. The second element is coupled to an intermediate shaft connected to a speed-increasing element of a simplex planetary gear set, which boosts the rotational speed of the input shaft. This innovative design reduces the torque on individual components, allowing for smaller sizes and capacities of the friction engagement elements. Another patent focuses on the output rotation of an engine being transmitted to a drive member when a vehicle starts moving. The drive member connects to a carrier of a speed-increasing planetary gear via a start clutch, which accelerates the rotation and transmits it to an input shaft. This system utilizes multiple friction engagement elements to shift speeds and transmit power to the output shaft effectively.
