A system of wheel tire pressure automatic signalling and protection of a mobile power facility against accidents includes a pressure sensor in the form of a bellow mounted on a brake drum with a movable flange and a rod with a roller, a membrane attached on a brake disc with a lock installed therein and a first movable pin, which interacts with the lock and by one end through the membrane - with the roller, and by the opposite end - with one end of spring, the second end of which - with a lid with a fixed contact with an adjusting screw with possibility of interaction with the opposite end of the first movable contact, a first signal lamp, a switch and a current source of standard on-board electrical system of mobile power facility connected through the first movable and fixed contacts to the first signal lamp. Additionally there are installed the second signal lamp, the second movable contact rigidly connected with the first movable contact and the third movable contact connected through an insulator and a spring with fixed contact. The first movable contact through the third movable contact and a switch can be connected to the first signal lamp, the second movable contact through the fixed contact - with the standard on-board electrical system and second signal lamp. |
