20110214950 | BRAKE DISC FOR RAILWAY VEHICLE - A brake disc for a railway vehicle, including a ring-shaped plate portion with a front side serving as a frictional surface and a plurality of fins being projected and disposed radially on the back side of the plate portion, the plate portion being fixed to a wheel, wherein a rib is provided between fins adjacent to each other, and a slit developing in the direction from a wheel-side face of the rib toward the back side of the plate portion is disposed in a circumferentially intermediate portion of the rib, thereby making it possible to suppress the deformation caused by frictional heat. | 09-08-2011 |
20120298458 | BRAKE LINING FOR RAILROAD CAR - A brake lining for a railroad car brake includes friction members which are pressed onto the sliding surface of a brake disc, and a back plate which is attached to a brake caliper in order to support the friction members. The friction members are dividedly arranged in a radial direction and in a circumferential direction of the brake disc. A disc spring is disposed between each respective friction member and the back plate. An outer peripheral surface of the friction members facing the back plate is formed in a convex curved shape in an area outside the elastic member. When a light pressing force is applied, a pressing force is transmitted from the back plate to the friction members via the disc springs. When a heavy pressing force is applied, the back plate and a rounded surface portion make contact, thereby directly transmitting a pressing force to the friction members. | 11-29-2012 |
20140238790 | BRAKE DISC FOR RAILWAY VEHICLE - A brake disc for a railway vehicle, including a ring-shaped plate portion with a front side serving as a frictional surface and a plurality of fins being projected and disposed radially on the back side of the plate portion, the plate portion being fixed to a wheel, wherein a rib is provided between fins adjacent to each other, and a slit developing in the direction from a wheel-side face of the rib toward the back side of the plate portion is disposed in a circumferentially intermediate portion of the rib, thereby making it possible to suppress the deformation caused by frictional heat. | 08-28-2014 |

20140097049 | BRAKE LINING FOR RAILWAY VEHICLES AND DISC BRAKE EQUIPPED WITH THE SAME - A disc brake for railway vehicles includes a brake disc fixed to a wheel or an axle of a railway vehicle and a brake lining configured to be pressed against a frictional surface of the brake disc by a brake caliper. The brake lining includes a plurality of friction members arranged to be spaced from each other, each of the friction members having a surface that faces the frictional surface of the brake disc, a metallic backing secured to back surfaces of the friction members, and a base plate supporting the friction members on the back surface side via spring members. The base plate is mounted to a brake caliper; wherein the friction members are provided in pairs with each pair being formed by two adjacent ones of the friction members, and the metallic backing is a one-piece member provided for each pair of the friction members. | 04-10-2014 |
20150147224 | STEEL FOR WHEEL - A steel for wheel contains, in mass %, C: 0.65 to 0.84%, Si: 0.4 to 1.0%, Mn: 0.50 to 1.40%, Cr: 0.02 to 0.13%, S: 0.04% or less and V: 0.02 to 0.12%, wherein Fn1 expressed by formula (1) is 32 to 43, and Fn2 expressed by formula (2) is 25 or less, the balance being Fe and impurities. P, Cu and Ni as impurities are P: 0.05% or less, Cu: 0.20% or less and Ni: 0.20% or less: | 05-28-2015 |
20150247541 | RAILWAY VEHICLE BRAKE DISC - A railway vehicle brake disc which can reduce aerodynamic sound raised high speed running, improve cooling performance during braking, and improve durability comprises a donut-shaped disc section having a sliding surface on a front surface side, a plurality of fin sections, each convexly provided in a rear surface of the disc section in a radial pattern, and a bolt hole passing through the disc section and the fin section. The disc section is mounted on a wheel in a state where the fin sections contact a plate section of the wheel using a bolt inserted into the bolt hole. The fin section has a groove formed along a circumferential direction in at least one of an area on an inner peripheral side and an area on an outer peripheral side of the bolt hole when viewed in a radial direction of the disc section. | 09-03-2015 |
