Latest Patents

Masui's latest patents include innovative designs for manual transmissions. The first patent describes a manual transmission that features a connection changeover mechanism. This mechanism changes the state of connection between the output shafts of the motor generator and the transmission based on the gear stage established by the driver's shift lever operation. When a low-speed gear stage is selected, a power transmission system is established, and the motor speed reduction ratio is set to a first speed reduction ratio. For intermediate speed travel, the system adjusts to a second speed reduction ratio, while for high-speed travel, no power transmission system is established between the output shafts.

The second patent outlines a transmission that includes an input shaft connected to an internal combustion engine and an output shaft linked to an electric motor. This design incorporates a gear stage specifically for electric vehicle (EV) travel, where no power transmission system is established between the input and output shafts. Additionally, it features multiple gear stages for hybrid vehicle (HV) travel, ensuring a seamless transition between power sources.
