Results of bench tests of the improved caliper mechanism of the disc brake with the new brake pads of the passenger car
A number of shortcomings was identified during the period of operation of passenger cars produced by JSC “TVZ” in the period from 2001 to 2015, both with the unified disc brake produced by JSC “TVZ”, which is installed in 1200 passenger cars, and imported brake equipment of German company Knorr-Brem...

| description | A number of shortcomings was identified during the period of operation of passenger cars produced by JSC “TVZ” in the period from 2001 to 2015, both with the unified disc brake produced by JSC “TVZ”, which is installed in 1200 passenger cars, and imported brake equipment of German company Knorr-Bremse (1764 passenger cars). To solve the problems of improving brake equipment in 2015-2016 CJSC “NO TIV” together with JSC “TVZ” designed and created a prototype of an improved caliper mechanism specially designed for use with a new friction pair - brake pads “Disk-254” with cermet manufactured by LLC “Disk” and 20Х13 steel disk with a diameter of 640 mm and a thickness of 40 mm. The results of bench tests, cyclic loading and comparative tests of the improved caliper mechanism enable to draw the following conclusions: Improved caliper mechanism in conjunction with the new brake pads “Disk-254” in a pair of friction with 20Х13 steel disc meets the requirements of standards for passenger cars with maximum speed of 200 km/h. Frictional properties of pads with cermet “Disk-254” fully comply with the requirements of GOST 33724.1-2016 “Pneumatic brake equipment of railway rolling stock. Safety requirements and methods of control. Part 1. Air distributors, driver cranes, brake blocks, rubber sealing products”. Specific volumetric wear of the brake pads “Disk-254” is 0.523 cm3/kWh, which corresponds to the requirements of cl. 4.7.2.16 of GOST R 55182-2012 “Passenger cars of locomotive traction. General technical requirements” and UIC CODE 541-3 “Disc brakes and its application. General conditions for the certification of brake linings”. At the same time, the wear resistance of the discs “Disk-254” is 3.45 times higher than the wear resistance of the “Chelyabinsk-8” pads. |
