DEVICE OF AUTOMOBILE TYRE COOLING

摘要

FIELD: machine building. ^ SUBSTANCE: automobile tyre liquid cooling device (9) comprises hydraulic pump (1) with electric drive (2) connected to tank (3) containing cooling liquid and to line (4) feeding the said liquid to braking mechanisms incorporating N.C. solenoid valve (5). Electrical drive (2) of hydraulic pump (1) is connected to power supply via switch (6) controlled by electromagnet (7). The device additionally incorporates a N.C. solenoid valve (5) with additional output, and nozzles (8) for cooling the automobile tyres (9) connected to the additional N.C. solenoid valve output (5) via line (10). Opening of the additional output is controlled by a threshold device (11) connected to temperature pickups (12) arranged on the side of tyre (9) nearby the running track. Threshold device (11) is connected into the electromagnet supply circuit (7). ^ EFFECT: ruling out heat destruction of tyres at higher motion speeds, tyres longer life. ^ 1 dwg
