摘要: An air dryer system for a trailer braking assembly is modified to provide a purge flow when the park brakes are actuated. An air reservoir, either the main air tank (44) or a separate reservoir (50), is in operative communication with the trailer air dryer (14). A valve (20) disposed at a supply end of the trailer air dryer selectively vents a purge flow to atmosphere in response to a park brake application. A restricting orifice (52) limits the purge flow through the trailer air dryer to extend the purge time and maximize the removal of moisture from the air dryer.

摘要: An emergency brake backup system is achieved by selectively interconnecting the air suspension as an additional reservoir to the air brake system. That is, if the charging system or primary reservoir fails, compressed air in the air spring reservoirs is used as an energy source to supply the pressurized air required for brake function. This can be achieved with minor modification to existing tractor and trailer brake systems that employ air suspension assemblies.
