Patent

CA 2201220

A rail car buffer has a capsule body and a spring assembly with an elastomer spring and a gas filled hydraulic spring in the body. Expansion of the buffer after collapse is snubbed by the gas filled hydraulic spring to convert energy stored in the elastomer spring to heat.

L'invention porte sur un dispositif d'amortissage d'un wagon porte-rails comportant un corps en capsule et un ensemble-ressort comprenant un ressort élastomère et un ressort hydraulique à gaz. L'expansion du dispositif d'amortissage après compression est arrêtée par le ressort hydraulique à gaz afin de convertir en chaleur l'énergie entreposée dans le ressort élastomère.
