TIRE CHECKING DEVICE Russian patent published in 2005 - IPC

FIELD: transport engineering.

SUBSTANCE: invention relates to automatic control of emergency situations on trackless vehicles, mainly heating and damage of vehicle tires. Proposed device contains magnetic circuits installed in tire uniformly over its circumference at least in two rows. Magnetic circuits of one of rows are made of ferromagnetic material with preset Curie point equal to maximum tolerable temperature of tire heating. Magnetic circuits of second row are reference ones, being made of ferromagnetic material with Curie point exceeding maximum tolerable temperature of tire heating. Electromagnetic sensors, AND-NOT gate, indicating unit are installed opposite to magnetic circuits of each row on structural members of track less vehicle at a distance from tire. Each electromagnetic sensors is provided with additional winding which is connected through corresponding switch to output of pulse generator, input of pulse generator being input of device.

EFFECT: provision of checking of device before beginning of movement and prevention of movement of vehicle if tire checking device is damaged.
