What are the functions of the friction plate, and are there any technical requirements when using the design plan? In response to this problem, I have already prepared an answer here, and I warmly welcome you to come and discuss it.
Analysis of the efficacy of the inner groove of the friction plate
1. Exhaust steam.
2. Reduce noise and change the resonance frequency of the product.
3. Discharge the grinding debris.
4. Improve the adhesion level between the friction material and the side plate.
Analysis of Technical Requirements for Friction Plates
1. Suitable friction coefficient
The friction coefficient is the most important parameter of the friction material, and the decision is basically the axle load of the automobile brake pad. The national standard strictly manages that manufacturers must indicate the coefficient of friction on the packaging. The coefficient of friction must be moderate. Too high will cause the wheels to lock up, uncontrollable azimuth and burn-in during the whole process of the braking system. If it is too low, the braking deceleration will be too long.
2. Reliable safety factor
Automobile brake pads will cause instantaneous high temperature when braking system, especially when the car is in motion or when the car is stopped in an emergency. At high temperatures, the friction coefficient of the friction plate will decrease, which is called thermal decay. The height of the thermal decay determines the safety in high-temperature situations and emergency shutdowns.
3. Satisfactory comfort
Comfort is an immediate reflection of friction characteristics, including brake system feel, noise, smoke, smoke, odor, etc. With the increase of private cars and the improvement of everyone's living standards, comfort is increasingly becoming the key index value of friction linings under the precondition of achieving safety. Among the comfort index values, car buyers usually pay attention to the noise of the car's brake pads. In fact, noise is also the most difficult problem that all friction material manufacturers can't solve. The noise is caused by the abnormal friction between the friction plate and the friction plate. The cause of the noise is more complicated. The braking driving force, the temperature of the brake pad, the speed of the car and the weather conditions may all be caused by the noise.
The above is a detailed introduction to the efficiency and technical requirements of the inner groove of the friction plate. I look forward to getting everyone's adoption.
