Latest Patents

One of Morishita's latest patents is a torque transmission device for a four-wheel drive vehicle. This device features a rotary housing connected to one of the front and rear drive shafts, which drive the front and rear axles. A rotary shaft, coaxially carried by the rotary housing, connects to the other drive shaft. The housing contains a multiple disc clutch device that transmits rotational power through friction engagement between alternately arranged outer and inner clutch discs. Additionally, the housing includes an axially movable piston that presses the clutch discs for friction engagement. The design incorporates a rotor with radially extending blade portions, which generates pressure within a circular chamber filled with high-viscosity silicon oil. This pressure is applied to the piston, enabling efficient power transmission.

Another significant invention by Morishita is a driving power transmission system. In this system, an input shaft is rotatably carried in a closed cylinder housing, extending through an operating piston. The operating piston is both rotatable with the housing and axially movable relative to it. A multiple disc clutch operable by the piston selectively transmits torque from the input shaft to the housing. The system also features a rotor that displaces silicon oil within an axially thin circular space, generating pressure during relative rotation. This innovative design enhances the performance of the transmission.
