Latest Patents

One of Noro's latest patents is a method of connecting two members using a pin. This innovative pin connection structure is utilized in a floating type brake disc assembly. The assembly consists of a hub and an annular disc that is concentrically disposed around the hub with a clearance in between. The hub and the disc feature multiple sets of semicircular connecting dents that open toward the clearance, forming respective inserting holes. A hollow pin is inserted into each of these holes, with a washer fitted on one end of the hollow pin, which is then caulked radially outward to secure the washer in place. The hollow pin is crafted from a metal that has a surface-treated layer, and the caulked end is shaped into a convex form in at least part of the end portion.

Another significant patent by Noro is related to a disk brake piston seal member and its manufacturing method. This invention aims to stabilize the friction coefficient of a dust seal member or brake-gap adjustment seal member attached to a piston in a disc brake, regardless of temperature fluctuations. The inner circumferential surfaces of both the dust seal member and the brake-gap adjustment seal member are coated with a friction-reducing agent to enhance performance.
