Latest Patents

One of Ethuo Shirai's latest innovations is a transfer apparatus for a vehicle. This apparatus features an input shaft connected to pinion shafts, enabling them to rotate in unison within a transfer casing. The design incorporates pinion gears that mesh with first and second differential side gears surrounding the input shaft. Remarkably, the first output shaft is created as a unitary body with the first differential side gear. A notable aspect of this invention is the compactness achieved in both axial and radial directions of the input shaft, thanks in part to a clutch mechanism positioned next to the first output shaft.

The innovative structure continues with the second differential side gear linked to a sprocket connected to a second output shaft. To facilitate the rotation transfer between either the input shaft or the second differential side gear to the clutch mechanism, either a differential casing or a component extending from the sprocket is designed for connection with the clutch mechanism. Furthermore, a bearing surrounds the differential casing, providing stable support and allowing for smooth rotation.
