Noise damping system on railroad wheels

摘要

A noise damping system for a railroad wheel: at one axial side of the wheel a groove is formed having radially inward and radially outward sides. A ring is installed in the groove. When one set of opposing sides, e.g. the radially outward sides, is engaged, they transmit torque. The ring and the groove are cooperatingly either trapezial in shape, that is one radial side inclined and one axial direction side, or are shaped with both radial sides uninclined. Screws secure the ring into the wheel and establish a torque transmitting connection between their opposing engaged sides. The ring may be in sections fastened together at the wheel to form the complete ring.
