RAIL WITH FRICTION CONTROL TREAD SURFACE FOR INNER RAIL, RAIL WITH FRICTION CONTROL TREAD SURFACE FOR OUTER RAIL, AND PERMANENT WAY |
摘要 |
This rail with a friction control tread surface for an inner rail includes an inner wheel contract surface that is provided so as to be curved along a line shape of a permanent, and is subjected to being in contact with an inner wheel of the rail car which rolls therealong. A plurality of grooves extending in a direction orthogonal to the line shape are formed on the inner wheel contract surface. This rail with a friction control tread surface for an outer rail includes an outer wheel contact surface that is provided so as to be curved along a line shape of a permanent way, and is subjected to being in contact with an outer wheel of the rail car which rolls therealong. A plurality of grooves extending in a direction of the line shape are formed on the outer wheel contract surface. |

1. A rail with a friction control tread surface for an inner rail, comprising:
an inner wheel contact surface that is provided so as to be curved along a line shape of a permanent way along which a rail car travels, and is subjected to being in contact with an inner wheel of the rail car which rolls therealong, wherein a plurality of grooves extending in a direction orthogonal to the line shape while being arranged at intervals in a direction of the line shape are formed on the inner wheel contact surface. |
