Latest Patents

Inoue's latest patents revolve primarily around advancements in disk brake systems. One notable patent describes a disk brake that includes an urging spring designed to urge a friction pad toward the exit side of a disk as a vehicle moves forward. This innovative urging spring is strategically positioned between a lug portion of the friction pad and a torque receiving surface of a carrier. The design incorporates a distal end configured to abut against the disk for wear detection, as well as a unique structure of the urging spring consisting of multiple sections, such as a mounting portion, first and second extending portions, a boundary region, and a bent portion. This configuration enhances the stiffness while aligning the natural frequencies in both the rotational and vertical directions.

Another significant patent by Inoue addresses the problem of braking noise. This invention suppresses noise when the vehicle moves backward by incorporating an urging spring that pushes the friction pad toward a rotationally exiting side of the disk. The spring's design utilizes an elastic plate material with a carefully adjusted spring constant to mitigate resonance frequencies that could lead to unwanted sounds. This innovative solution has the urging spring positioned outside the radial center of the hook portion, enhancing its effectiveness.
