Railway Suspension System Elements of Yaw Damper
Product Overview
A hydraulic railway damper is a device designed to absorb and reduce shock impulses incurred when a railcar is in motion. Dampers also help reduce noise and track wear. They operate on diesel and electric locomotives, passenger mainline coaches, and diesel and electric multiple-unit trains. It can be divided into 4 categories. Primary Vertical damper, Secondary vertical/lateral damper,Yaw damper and Coupling damper. For here we will introuce yaw damper, it controls the sine wave effects of the bogie, increasing safety at medium and high speeds.
