Title: Kevin J Johnson: Innovator in Hydrostatic Transmission Technology
Introduction
Kevin J Johnson is a notable inventor based in Salem, Indiana, who has made significant contributions to the field of hydrostatic transmission technology. With a total of five patents to his name, Johnson's work focuses on enhancing the efficiency and functionality of variable speed transmissions.
Latest Patents
Among his latest patents is the "Neutral start switch and adjustment assembly for a hydrostatic transmission." This invention involves a hydrostatic transaxle assembly that connects to a power source activated through an electric starter circuit. The assembly features an axial type hydrostatic transmission module with a pump containing multiple axially arranged cylinders, each housing a piston. A tiltable swash plate engages with these pistons, allowing for fluid displacement within the pump. The neutral switch is fixed relative to the transmission casing, detecting the neutral position to enable the electric starter. Additionally, the neutral adjustment assembly includes a control rod and a two-piece shift lever, which allows for precise adjustments to the neutral position.
Another significant patent is the "Electric shifting of a variable speed transmission." This invention describes a variable speed transmission that includes a rotatable input member and a fluid pump. The fluid motor, in communication with the pump, drives the output speed, which can be selectively varied. A reversible electric motor is integrated into the system, allowing for mechanical engagement with the displacement varying means, thus enabling efficient control over the output speed.
