Latest Patents
Tojo's latest patents include a transmission apparatus designed for dual clutch transmissions. This innovative design features a planetary gear mechanism that integrates with a first input shaft connectable to an internal combustion engine via a first clutch. The sun gear rotates integrally with the first input shaft and an electric motor, while a ring gear is fixed to a case. A synchromesh mechanism allows for the selection of predetermined speed stages, enhancing the efficiency of the transmission system.
Another significant patent is a control apparatus for a vehicle power transmission mechanism. This system calculates the clutch output rotation change rate and adjusts the clutch engaging force accordingly. By decreasing the engaging force when the output rotation change rate is positive and increasing it when negative, the apparatus effectively suppresses clutch juddering, which can occur due to discrepancies between input and output rotational speeds.
