20100163353 | FRICTION COUPLE - A friction couple including: a first friction member that contains a metallic material and includes a first friction surface; and a second friction member that includes a second friction surface that contacts the first friction surface and that contains an oxidation film developer that accelerates formation of an oxidation film on at least one of the first friction surface and the second friction surface by oxidizing the metallic material when the first friction surface and the second friction surface contact each other. | 07-01-2010 |
20100174010 | FRICTION MATERIAL AND PRODUCTION METHOD OF FRICTION MATERIAL - A friction material including: an amorphous resin that has a chain-like polymer structure; and other components that constitute the friction material and that are components other than the amorphous resin, wherein dispersion treatment is preliminarily carried out in which the amorphous resin is dispersed in at least one of the other components, and a manufacturing method of the friction material. | 07-08-2010 |

20110281962 | FRICTION MATERIAL AND PRODUCTION METHOD OF FRICTION MATERIAL - A friction material including: an amorphous resin that has a chain-like polymer structure; and other components that constitute the friction material and that are components other than the amorphous resin, wherein dispersion treatment is preliminarily carried out in which the amorphous resin is dispersed in at least one of the other components, and a manufacturing method of the friction material. | 11-17-2011 |
20120037465 | BRAKING DEVICE AND METHOD FOR MANUFACTURING FRICTION MATERIAL - A braking device is provided with a pad having hard particles on a wavelike friction surface, and a disc having a hard layer on a wavelike friction surface which slides on the wavelike friction surface. The wavelike friction surface has a groove portion in a direction in which the wavelike friction surfaces slide on each other, and the wavelike friction surface has a protruding portion which abuts on the groove. Therefore, the actual contact area between the friction surfaces having the hard members is increased, and a higher frictional force can be obtained without sacrificing wear resistance. | 02-16-2012 |
20120073914 | BRAKE SYSTEM AND METHOD FOR PRODUCING FRICTION MATERIAL - A brake system includes a pad having a frictional surface, and a disc having a frictional surface sliding on the frictional surface. The frictional surface includes hard particles supported elastically and a plurality of protrusions arranged along a direction in which the frictional surface slides on the frictional surface, and when the frictional surface slides on the frictional surface, particles abut respective protrusions continuously while being displaced in the direction perpendicular to the frictional surface. Thus, wear resistance can be improved Since only the vicinities of the peaks of the hard particles and the vicinities of the peaks of the protrusions abut, the hard particles do not follow irregularities of the frictional surface, and thereby the hard particles and the protrusions repeat point contact. Thus, since the distance between the hard particles and the protrusions is stabilized and the adhesion frictional force is stabilized, a stable frictional force can be obtained. | 03-29-2012 |
20120194142 | POWER GENERATING DEVICE AND BRAKING DEVICE - Power generation efficiency is improved with a simple configuration. A braking device is provided with a brake rotor which rotates on a central axis, and friction portions which are in frictional contact with the brake rotor. A coil is wound around the outer peripheral portion of the brake rotor. A friction portion has the north pole of a magnet, and a friction portion has the south pole of a magnet. The braking device generates electricity by using an electromagnetic induction phenomenon and an electrostatic phenomenon that are caused by the interaction between the outer peripheral portion and the friction portion, for example, at the time of braking. As a result, the configuration can be simplified and the amount of power generation is not likely to be limited by a motor capability because there is very little need to use the motor as a generator. Furthermore, the friction energy itself converted from the kinetic energy of the brake rotor can be converted into electrical energy to suppress the friction energy from being lost as heat energy. | 08-02-2012 |
20140167491 | WHEEL COVER - When removing a wheel cover from a wheel, force in an inner peripheral direction is applied to one end portion of an engaging member. The engaging member pivots (including elastically deforms) about the other end portion, such that an engaging protruding portion pivots and comes away from an engagable protruding portion. As a result, a center attaching portion is able to be removed from an ornament receiving hole, thus enabling the wheel cover to be removed from the wheel. | 06-19-2014 |
20140360820 | DISC ROTOR - Provided is a disc rotor formed of graphite-containing cast iron and having high corrosion resistance. For a disc rotor formed of graphite-containing cast iron, after removal of graphite present adjacent a surface of the disc rotor through a graphite removing treatment, a nitride layer and an oxynitride layer are laminated one after another on the surface through a gas nitrocarburizing treatment. | 12-11-2014 |
