Title: Masafumi Imasaka: Innovator of Advanced Power Transmission Technologies
Introduction
Masafumi Imasaka, an inventive mind based in Hamamatsu, Japan, has made notable contributions to the field of power transmission devices. Holding three patents to his name, Imasaka's work primarily focuses on enhancing the efficiency and drivability of astride-riding vehicles.
Latest Patents
Among Masafumi Imasaka's latest innovations is the "Power Transmission Device for Astride-Riding Vehicle." This device integrates a torque converter and a clutch in series within the transmission route between an engine and a gear speed change device. The design allows the pump capacity of the torque converter to peak at a speed ratio of zero, gradually decreasing with increased speed ratio. This feature results in linear acceleration characteristics for both the engine and turbine rotational speed, ultimately improving drivability.
Another significant patent by Imasaka is the innovative "Torque Converter." This design cleverly positions a radial bearing and a one-way clutch concentrically between the hub of the side cover and the turbine shaft, which extends through the hub. The output gear's hub is coupled to the turbine shaft, and the inner peripheral surface of the hub features a larger-diameter section at the base that transitions to a smaller-diameter section at the tip through an annular step. This configuration ensures the radial bearing is securely clamped, enhancing the torque converter's performance.
