Air pressure adjusting automatic system in the truck tires is intended to improve cross-country ability of a vehicle on the complicated road passages as well as to provide possibility to keep moving without replacing wheel in case of minor damage of its inner tube.
Stable functioning of the air pressure adjusting system quite often gets broken as a result of lip-type seal wear. It occurs because of friction against the surfaces of the mated bushings.
While the rubber cuff is scuffing, a gap forms what results in pressure fall in the tires.
In order to reduce friction in the bushing-to-cuff pair, and to prevent negative consequences of rubber parts scuffing, the producers of the automotive components apply MODENGY 1006 anti-friction solid-film coating based on molybdenum disulfide and graphite, and MODENGY 1009 based on polytetrafluorethylene onto the surfaces of the bushings.
Due to this, friction between the bushings and the cuffs reduces, smoothness of going increases, service lifetime intends, and reliability of parts operating improves.
These coatings are applied onto the bushings by the method of spraying out of
These products have high wear resistance, and require no frequent renewing.
Use of the coatings enables to reduce risk of the tire air pressure adjusting automatic system fails, and to extend service lifetime of its components.
