“…The brake disc surface temperature is recorded with a PYROVIEW 640 L compact long-wave high-pixel infrared thermal camera. The emissivity is set to 0.75 (Rao et al , 1989; Xu et al , 2011). Before each formal experiment, the brake disc is fully cooled lower than 60°C.…”

Purpose This study aims to clarify the relationship of friction material type and brake disc temperature through braking experiment. Design/methodology/approach The braking performances of resin materials (RM), semimetallic materials (SM) and copper-based powder metallurgy materials (PM) friction blocks mating with forged steel brake disc were examined based on TM-I-type reduced-scale inertial braking dynamometer. The brake disc surface temperature was recorded by infrared thermal camera during braking. Findings Experimental results indicate that the thermal wear resistance of three friction materials differs with mental content, resulting in the deviation of pad-disc system contact state during braking, thus forming different temperature distribution on the brake disc surface. The peak temperature on the disc face of RM (190°C) is 36.6% and 45.4% lower than that of PM (300°C) and SM (348°C) at 160 km/h. The maximum radial temperature deviation of PM (35°C) is approximately three times than that of RM (12°C) and 40% higher than that of SM (25°C) at 50 km/h, whereas the maximum temperature deviation of SM (97°C) is six times than that of RM (16°C) and 31% higher than that of PM (74°C) at 160 km/h. Originality/value The effect of friction material type on the disc surface temperature distribution is revealed, which provides a meaningful reference for the design of brake friction pairs and choice of brake pad materials.

“…the temperature of the region where the inner wall of the brake drum and the friction lining are in long-term contact is relatively high; the farther away from this position, the slower the temperature rises. Therefore, the position of arc spray device should be set at the position where more heat is generated, and the area where less heat is generated can be cooled by water spray conduction or heat conduction [5].…”

Many domestic traffic accidents are caused by high-temperature friction of truck’s brake drum resulting in failure of brake system. Therefore, it is the key to solve the problem of decline on brake drum performance caused by temperature. The following schemes are mainly adopted: improving brake structure and friction materials, adding auxiliary brake devices, and installing cooling devices for brake system. This paper summarizes the structure and characteristics of most intelligent cooling devices for brake system in China. In addition, based on these intelligent cooling devices, the paper also puts forward new intelligent cooling devices for truck’s brake system. The system uses sensors to analyze the temperature state of the brake drum. According to the analysis results, the central controller innovatively combines air pump and water pump to transform low-pressure water into high-pressure water, and then sprays and cools the brake drum through the water pipes and arc spray devices to ensure the normal operation of the brake system.

“…They believed, whole friction force was transformed into kinetic energy and that there was macroscopic communication into the rotor of disc and pad. Rao et al [33] have used this into slipping parts of disc brake assembly because of thermoelastic instability for their study of the difference in temperature in the disc brake because of repetitive braking (fade). Because of non-uniform heat flux generation at the disc surface, thermal stresses are generated.…”

The most significant feature of the car that ensures security and comfort is the brake. Over time, disc brakes have grown to be compatible to decelerate and stop the car. This is the most important aspect of the vehicle that is often showing the nonlinear thermo elastic transient conditions. For numerous uses, there are various prototypes of disc brake systems. A comprehensive overview of the different geometries of the components and numerical analysis of solid disc is given in this study. So many disc brakes related operating problems need to be understood by considering all the changes. Substantial studies on these challenges have been carried out and are continuing, and various approaches are being suggested to remove or minimize them at the same time. This research would be useful in explaining brake system changes and efficiency, in increased fuel consumption, and in reducing the weight of vehicles. And the products used in previous experiments and the use of various synthetic materials are also discussed. The analysis shows that, by actually emulating all the applicable realistic scenarios, there is ample space for extended research to realize optimum disc brake system architecture.
