The invention relates to a truck brake online temperature measuring device and an implementation method. The truck brake online temperature measuring device is characterized in that a brake temperature wireless receiving circuit which is arranged in a shell II is placed in an automobile cab; a heat-insulating bracket is fixed to a hub reduction gear in an automobile hub; a heat-insulating plate is fixed onto the heat-insulating bracket; shells I of a plurality of groups of brake temperature wireless receiving devices are fixed onto the heat-insulating plate; probes of high-temperature thermocouples T which are connected with the brake temperature wireless receiving devices in the shells I are attached into the automobile hub respectively at intervals; brake drum temperature online acquiring and transmitting modules and the brake temperature wireless receiving devices are connected wirelessly. The truck brake online temperature measuring device has the effects that when the hub temperature exceeds a set value 500 DEG C, a system early-warning state is started to inform a driver that the brake drum temperature is high slightly; when the temperature exceeds 600 DEG C, an alarm is sounded to inform the driver of parking and checking immediately. Thus, the accidents of brake failures, spontaneous combustion and the like caused by brake overheating under unknown conditions are effectively prevented.
Description
technical field [0001] The invention relates to an on-line temperature measuring device for a truck brake and a realization method thereof, which can also realize real-time temperature monitoring of the drum brake of a passenger vehicle. Background technique [0002] The brake is a component in the braking system that is used to generate braking force that hinders the movement or movement tendency of the vehicle. Except for various slowing devices, automobile brakes are almost all friction brakes that use the friction between the fixed element and the working surface of the rotating element to generate braking torque. [0003] At present, the friction brakes widely used in various types of vehicles can be divided into two categories: drum type and disc type according to the different rotating elements. The difference between them is that the rotating element in the friction pair of drum brakes is a brake drum, with its cylindrical inner surface as the working surface; the r...
