Latest Patents

Ito's latest patents focus on innovative electric power steering apparatus designs. His first notable invention involves a unique bearing configuration for a worm that is interlocked with a steering assist motor. This design incorporates elastic members that restrain the bearing's radial movement and differ in force depending on their circumferential position. By doing so, it effectively reduces backlash at the meshing interface of the worm and worm wheel, while minimizing the rotation torque needed at this point.

The second patent elaborates on an electric power steering apparatus wherein the worm shaft is movable in a radial direction. This design features a pressing body that utilizes a V-shaped contact to engage with the shaft at two circumferential points. Additionally, an annular elastic body restricts movement in a direction crossing the radial axis, promoting greater stability and control during steering operations.
