Research On Monitoring And Early-warning System Of Truck Brake System Temperature

The brakes are important safety components of vehicles, driving in the vehiclesafety and reliability of vehicle parking is extremely important role. Truck continuouslong downhill braking, the brake load, poor driving environment, prone to heat arecession, which could affect the vehicle’s braking brake performance from the greatlyincreased security, greater safety on the brake effects. Therefore, study thetemperature of brakes, monitor the temperature of the brake system information inreal-time and delivery them to the driver timely, this will control the temperaturelower than the safety temperature in driving. In this method, the braking thermalperformance of the phenomenon of the recession will be effectively reduced, andensure sufficient braking performance of the brakes which fitted with drum brakes onheavy vehicles laden with significance.In recent years, road traffic safety situation is increasingly grim in China, andfrequent accidents of major malignant become larger. According to the informed Dataof the Ministry of Public Security Traffic Management Bureau, safety of trucktransport of road traffic safety has become one of the major focus on accidents, whileaddressing the problem of road traffic safety has become one of the important nationalauthorities to improve transportation security initiatives. In this paper, combinethe"863" project "Operating performance of truck safety technologies and integratedmonitoring and early warning device" analyzes the main factors affecting brakeperformance of brakes themselves for the continuous braking situation, including thetemperature of brake shoe friction lining, the braking torque and the wear of brakeshoe. Study the temperature rise situation of brakes during the brake; focus on themain reasons for failure under braking, use the relationship of energy conservationtheorem with the speed, braking distance, brake temperature, deduce the relationshipformula between the brake temperature with the braking safety distance when it’sfully loaded vehicle with different slope; research on the location of drum brakesystem highest temperature, design and develop the truck brake system temperaturemonitoring and early warning systems to monitor the temperature of brake system inreal-time. When the temperature reaches the preset alarm temperature (thetemperature of the upper limit of safe driving), audible and visual alarm appear,prompting the driver to slow down, or drive into emergency seating area to stop untilthe temperature returns to normal and then move on. Thereby, improve truck traffic safety and reducing traffic accidents to provide protection for truck safety of peopleand vehicles...
