Problems solved by technology
Large trucks have the characteristics of large cargo capacity and heavy tonnage, especially when driving on mountainous roads with continuous downhill slopes, the temperature rise of the brake drum will cause the temperature of the brake drum and brake shoes (brake pads) to rise, resulting in thermal decline of braking performance , resulting in potential hidden dangers
Looking back at the more serious safety accidents in road transportation, it can be seen that most of the production accidents caused by large trucks on long downhill roads were caused by the excessive temperature of the brake drum when the large trucks went down the long slope continuously, causing the braking Severe thermal degradation of the system, eventually causing the large truck to stall and causing serious safety accidents

The invention discloses an early warning method for the temperature rise of a truck brake drum. Firstly, the load capacity of the truck is obtained on the uphill road section before the truck enters the long downhill road section; Take the initial braking speed at the braking moment, the braking time and the braking end speed at the end of braking; then predict the temperature rise of the brake drum of the truck during the braking process and the current temperature rise of the brake drum of the truck; finally According to the load capacity of the truck and the current temperature rise of the brake drum of the truck, the danger degree of the truck is judged, and an early warning is given to the truck according to the degree of danger. The method of the invention combines the actual load capacity of the truck and the actual temperature rise of the brake drum to effectively warn the driver of the truck and prevent accidents.
Description
technical field [0001] The invention relates to the technical field of road traffic safety, in particular to a method for early warning of temperature rise of a truck brake drum. Background technique [0002] With the development of the transportation industry, road transportation occupies an important position in the transportation industry due to its characteristics of flexibility, convenience, high degree of freedom of extension and wide coverage, especially for long-distance transportation of large trucks. main force. Large trucks have the characteristics of large cargo capacity and heavy tonnage, especially when driving on mountainous roads with continuous downhill slopes, the temperature rise of the brake drum will cause the temperature of the brake drum and brake shoes (brake pads) to rise, resulting in thermal decline of braking performance , resulting in potential hidden dangers. Looking back at the more serious safety accidents in road transportation, it can be s...
