CHASSIS OF MILITARY CATERPILLAR VEHICLE Russian patent published in 2008 - IPC F16D71/00 F16D65/14 F16D23/14 F16D25/04 F16D55/00 

FIELD: security facilities, blasting.

SUBSTANCE: invention refers to armoured machinery and can be used in chassis of military caterpillar vehicles equipped with fire protection facilities. The chassis of a military caterpillar vehicle contain a frame, a power unit, a power gear including a fan drive with a friction clutch and a cooling system with a fan, and fire protection equipment with an automatic control unit. The fan is secured on a driving hub made with a friction surface. A pressure plate is designed so as to interact with the friction surface of the driving hub. A driven hub is made as a whole with a body of a bearing and is equipped with a cartridge located in its inner cavity and able to rotate around its axis. A chamber forming container is assembled in the cartridge; and an exploder as a source of pneumatic energy is installed in the said container. At that the container is designed with an orifice hole communicating the inner cavity of the container with the chamber and rigidly connected to the driven hub. A feature of electric blasting of the charge of an explosive substance of the exploder is secured to a flange of the container. The said feature is made as a lock with a core. The core is electrically connected with the said automatic control unit, and the lock is equipped with a spring which presses the core to a detonating cap of the exploder.

EFFECT: improvement of fire extinguishing efficiency in a motor-transmission compartment of chassis of a military caterpillar vehicle with hydro mechanic transmission.
