Abstract:

Due to ensure the heavy load and fast speed，oversize vehicles could only use the safety when going downwards. The brake disc result  would rise
in temperature continuously,  which lead to the “thermal recession"  and finally，result in the brake failing to work. Based on the analysis of the existing technologies to reduce the temperature of the vehicle wheels, a new automatic cooling and alarm control device was designed. When the wheels are in high temperature，the microcontroller will receive the signal via temperature detector. Then it will give a voice warning to the driver who can use compressed air to cool the brake disc with the help of air blower.


 

Key words: oversize vehicle, thermal recession, cool and alarm automatically, control device
