The Main Performance Of The Brake Pads
Brake pads are also called brake pads. In the car's braking system, the brake pads are the most critical safety parts, all the braking effect is good or bad brake pads play a decisive role, so that good brake pads are the protection of God and the car.
Brake pads are friction materials fixed to brake drums or brake discs that rotate with wheels, where the friction linings and friction pads are subjected to external pressure to create a friction to achieve the purpose of vehicle deceleration. The structure of the brake pads generally by the steel plate, Brake Pad bonding insulation layer and friction block composition, steel to be coated to rust, coating process with SMT-4 furnace temperature tester to detect the temperature distribution of the coating process to ensure quality. The insulation layer is composed of non-heat transfer material, the purpose is to heat. The friction block is composed of friction material, adhesive, brake is squeezed in the brake disc or brake drum on the friction, so as to achieve the purpose of vehicle deceleration brake. Due to friction, Brake Pad the friction block will gradually be worn, in general, the lower the cost of the brake pads wear faster. After the use of friction material to replace the brake pads, or steel plate and brake disc will be in direct contact, and ultimately lose the braking effect and damage the brake disc.
In the conventional manufacturing process, the friction material used on the brake pads is a mixture of a plurality of binders or additives, and the fibers are added thereto to enhance their strength and to reinforce. Brake manufacturers in the use of materials on the announcement, Brake Pad especially on the new formula is often tight-lipped, of course, some ingredients such as: mica, silica, rubber debris, etc. are open. The ultimate effect of brake pads, anti-wear, anti-temperature and other properties will depend on the relative proportions between the different components.
The main performance of the brake pads: In general, the basic requirements of the brake pads are mainly wear resistance, friction coefficient, excellent insulation performance.
1, high performance: high friction coefficient (gold Kirin ceramic brake pads friction coefficient of 0.45, are high friction coefficient brake pads), high temperature, high speed and high temperature driving process in the outstanding performance, driving high-speed high temperature braking effect And the brake comfort is good.
2, safety: low thermal decline, good recovery performance, Brake Pad mountain roads and high temperature, high-speed braking performance is not reduced. To maximize the safety of the vehicle. Very suitable for use with mountain road area, high speed to various other road conditions!
3, comfort: brake comfort, no noise, no pollution, brake balance.
4, a reasonable life: the general non-modified vehicles, Brake Pad in the normal driving situation, the front brake brake pads life of 3-5 million kilometers, after the brakes brake life of 8-10 million km. Front brake disk life of 6-10 million km. Of course, often in the mountains driving the car brakes and discs life is much shorter.
5, the lower powder rate, brake pads friction coefficient: refers to the friction between the two surfaces and the role of the vertical force on the ratio of a ratio. It is related to the roughness of the surface, regardless of the size of the contact area. According to the nature of the movement, Brake Pad it can be divided into dynamic friction coefficient and static friction coefficient. The most important performance index of the brake pads is the coefficient of friction. National standards for the provisions of the brake friction coefficient between 0.35-0.40. Qualified brake pad friction coefficient is moderate, stable, if the friction coefficient is less than 0.35, the brake will be more than the safety brake distance or even brake failure, if the friction coefficient is higher than 0.40, Brake Pad the brake is easy to lock, there is rollover accident.
Brakes are usually made of steel plate, adhesive insulation layer and friction block, the steel plate to be coated to rust, coating process with SMT-4 furnace temperature tester to detect the temperature distribution of the coating process to ensure quality.
