Latest Patents

Oshidarai holds a patent for a "Speed change controller for infinite speed ratio transmission." This invention involves a system where the rotation of an input shaft is directed to both a continuously variable transmission (CVT) and a fixed speed ratio transmission. The design integrates a CVT output shaft connected to a sun gear of a planetary gear set, while the output shaft of the fixed speed ratio transmission is linked to a planet carrier of the same gear set. The vehicle is driven by the output of a ring gear from the planetary gear set. The controller for this infinite speed ratio transmission includes an actuator that adjusts the torque transmitted between the input shaft and the CVT output shaft. A microprocessor manages the actuator to ensure that torque in the opposite direction to the vehicle's travel is not transmitted by the continuously variable transmission.
