AMTRAK/KNORR Disc Brake Study. Volume I. Final Report

摘要

This report describes the Amtrak/Knorr Disc Brake Study which was developed: to evaluate candidate replacement disc brakes for the Knorr disc brakes presently in use on Amfleet and Turboliner cars; to explain the cause of the loosening of the attaching pins and the excessive wear experienced by the disc-brake friction ring on the Knorr disc brakes; and to find out why the disc brake failure rate was much higher when the outside temperature was below 32 degrees Fahrenheit. This report covers the first six months of a three-year controlled revenue service test, an over-the-road test, and laboratory tests to correlate over-the-road test results to pin wear.
