Latest Patents

One of his latest patents is for a motor grader that includes an engine, a torque converter, a drive wheel, an engine revolution detector, and a control unit. The torque converter, which features a lock-up clutch, effectively transmits driving force from the engine. The drive wheel is rotationally driven by this force, while the engine revolution detector monitors the engine's performance. The control unit is designed to maintain the engaged state of the lock-up clutch when the engine revolution exceeds a predetermined threshold, ensuring optimal performance.

Another significant patent is for a steering-wheel revolution number correction system in all-wheel-drive vehicles. This system calculates the turning radius based on the steering angles of the wheels and the articulation angles of the frames. It automatically adjusts the rotation of the steering wheels to be faster than the rear wheels, based on various factors such as turning radius and engine speed. This innovation eliminates the conventional difficulties associated with operating a motor grader, allowing for easier and more accurate control.
