Title: Takeo Ishihara: Innovator in Engine Technology
Introduction
Takeo Ishihara is a prominent inventor known for his contributions to engine technology. He is based in Asaka, Japan, and has been awarded a total of 7 patents throughout his career. His innovative designs focus on improving the efficiency and functionality of engine-driven vehicles.
Latest Patents
One of Ishihara's latest patents is a drive system for engine-driven light vehicles. This system transmits engine rotation to a wheel through a friction roller during normal engine operation. It also allows the wheel rotation to start the engine via the same friction roller. The design includes a power transmission means, such as a gear train, which is interposed between the drive shaft and the crankshaft of the engine. A one-way clutch is utilized to transmit the drive shaft rotation to the crankshaft with a preset speed change ratio for engine starting. Additionally, a planetary gear is coupled to the gear train, enabling the crankshaft rotation to be transmitted to the drive shaft with a large reduction ratio.
Another significant patent is a power unit specifically designed for three-wheel vehicles. This power unit employs a single-cylinder, two-stroke engine that drives a centrifugal clutch, a gear train, and a drive shaft to one wheel. The drive shaft is rotatably mounted within the engine housing and the crankshaft. To accommodate the asymmetric power distribution to one rear wheel, the drive shaft, crankshaft, and engine cylinder are canted from alignment with the vehicle's centerline.
