HYDRAULIC DRAFT GEAR FOR LOCOMOTIVES

During the past two decades the weight of road locomotives has more than doubled, but the draft gears have not advanced at the same rate. The author, in order to offer improved impact cushioning characteristics, proposes a hydraulic draft gear and gives a mathematical model to illustrate the improved cushioning behavior. A system of valves provides train handling characteristics. An alignment coupler and plunger arrangement provide lateral force reduction during locomotive braking.
