SUPPLY PNEUMATIC SYSTEM FOR TRUCK TRAILERS AND COMPRESSED AIR SUPPLY METHOD Russian patent published in 2015 - IPC B60T13/26 

FIELD: transport.

SUBSTANCE: set of inventions relates to road transport, particularly to vehicle pneumatic braking systems. Supply pneumatic system includes the first air mains, the second air mains and supply air line coupling. The first air mains is intended to deliver limited air pressure (P₁) to pneumatic braking system of trailer. The second air mains is intended for higher air pressure (P₂). The air line coupling is installed between truck and trailer to deliver compressed air. The air line coupling is designed for higher air pressure (P₂) than air pressure (P₁) of pneumatic braking system. To the second air mains, one tire pressure regulation system and one suspension and damping system are connected. Method of compressed air delivery to trailers consists in the following: air pressure (P₂) is created in truck which pressure is higher than limited air pressure (P₁) for braking systems of trailers. Then, higher air pressure (P₂) is transferred via air line coupling designed for higher air pressure (P₂) than limited air pressure (P₁). Whereupon air pressure (P₁) is delivered to the first air mains of trailer, and higher air pressure (P₂) is delivered to the second air mains via air line coupling, herewith, together with supply of the first air mains of trailer the second air mains are supplied with higher air pressure (P₂).

EFFECT: improved compressed air delivery to truck trailer, as well as possibility to deliver adequate higher air pressure not only to trailer braking system but also to other compressed air consumers in the trailer.
