System of monitoring and early warning for temperature of truck Brake shoe

For truck brake shoe early-warning temperature dynamic detection, this paper proposes a temperature detection device for brake shoe based on thermocouple temperature sensor, and by using ANSYS finite element analysis method to analyse the brake drum brakes, brake shoe linings in the process of the location of the maximum temperature, and determined the brake temperature of the brake safety threshold. To liberate the acetate II heavy commercial vehicles for the test vehicle, MC9S12XEP100 microcontroller as the car terminal, designed and developed brake shoe temperature dynamic detection warning system platform, and researched. The experimental results show that the temperature measurement error is less than or equal to 4%, which verifies the accuracy and feasibility of this method for dynamic detection of the temperature of the warning hoof.
