Abstract:
1. A compressed air supply system for a truck trailer, comprising: at least one first compressed air network, which supplies a pneumatic brake system of the truck trailer with an air pressure limited according to a requirement for the truck trailer; at least one compressed air supply coupling between a tractive vehicle and the truck trailer for supplying compressed air; wherein the at least one compressed air supply coupling is configured for a higher air pressure than the limited air pressure according to the requirement, wherein the at least one compressed air supply coupling is connected to supply a further supply network for the truck trailer with compressed air, and wherein the further supply network includes at least one of a tire pressure monitoring system and an air suspension and damping system, and wherein the tractive vehicle produces the limited air pressure, which is stored in a compressed air accumulator of the tractive vehicle, wherein a pressure relief valve responds as soon as the limited air pressure is exceeded, and wherein a higher air pressure is further produced in the tractive vehicle and stored in another compressed air accumulator of the truck trailer, which is protected by another pressure relief valve of the truck trailer.
