What are the types of brake friction pads?

With the improvement of people's living standards, friction plate friction materials and everyone has been closely connected, in people's daily life, everywhere can be seen a variety of friction plate friction materials to bring us convenience, which can be roughly divided into the following categories.

1. Rubber-based friction materials: The main formula of this kind of friction material friction plate is rubber, cork and fiber, which does not contain asbestos, which can play a good friction coefficient, and can meet the basic requirements of wear resistance, no noise and environmental protection, and is a commonly used material in motorcycle clutches.

2. Paper-based friction materials: This kind of friction material friction plate is mainly made of imported carbon fiber, aramid and imported resin, which can be used for racing cars and large-displacement motorcycles, especially its friction coefficient is very stable, the high-temperature friction coefficient decay is very small, ablation resistance, and good thermal recovery performance (after the high-temperature clutch slips, the friction coefficient quickly returns to the original state after the clutch is cooled).

3. Resin-based friction materials: This kind of friction material friction plate is mainly made of reinforcing fiber, friction powder and resin, which has the characteristics of high hardness, wear resistance, high temperature resistance of 350 degrees, etc., and is mainly used in various mechanical clutches and motor reducers, and its performance is comparable to that imported from Taiwan.

4. Carbon fiber friction material: This kind of friction material friction plate is mainly made of carbon fiber, imported rubber and imported cork as the main raw materials, processed by high-quality technology, with high temperature resistance of 350 degrees, wear resistance of 25,000 kilometers, no noise, no slip and ablation resistance, etc., is a fine friction material.

5. Semi-metallic friction materials: This kind of friction material friction plate is mainly made of rubber, friction powder, fiber and metal fiber, the product has the characteristics of wear resistance, super hardness, high friction coefficient, etc., and is the best partner used in mechanical clutch and motor brake system.

Brake friction plate friction material requirements for the fiber components used:

1. Good enhancement effect.

2. Good heat resistance, no fuse, carbonization and thermal decomposition will occur at the friction working temperature.

3. It has a basic coefficient of friction.

4. The hardness should not be too high, so as not to produce braking noise and damage to the brake disc or drum, and the process operability is good.

5. Filler The filler in the friction material component is mainly composed of friction performance modifier and compounding agent.

Brake friction pads can be divided into brake pads (disc pads, drum pads), brake belts, brake shoes, clutch pads, and heterosexual friction pads according to the shape of the product. The disc is planar and the drum is curved. The brake shoe (train brake shoe and oil drilling rig) is an arc-shaped product, but it is much thicker than the ordinary arc brake pad, with a range of 25 to 30mm.

Brake belts are often used in agricultural machinery and construction machinery, and are soft friction materials. Clutch plates are generally made in the shape of a ring. Heterosexual friction plates are mostly used in various construction machinery, such as friction presses, electric hoists, etc.

One rubber-based friction material, two paper-based friction materials, three resin-based friction materials, four carbon fiber friction materials, and five semi-metal friction materials.

The function of the friction plate is to produce friction between the brake caliper, which is also the first of the braking force, and the friction plate will transmit the braking force to the tire, so that the tire rubs the ground braking, in addition, the friction plate also plays a role in heat dissipation to prevent the attenuation of the braking force.

Disc brakes, also known as disc brakes, are mainly composed of brake discs, brake calipers, friction pads, cylinders, oil pipes and other parts.

Disc brakes pass through the hydraulic system.

The pressure is applied to the brake caliper, so that the brake pads rub against the brake disc that rotates with the wheel, so as to achieve the purpose of braking.

Since the disc brakes are open. The heat generated during braking can be quickly dissipated, and it has good braking efficiency, and is now widely used in cars.

On the basis of common disc brakes, in order to improve the heat dissipation effect during braking and further improve the braking performance, ventilated brake discs came into being.

A friction brake is a mechanical part that stops or slows down a moving part in a machine. Commonly known as brakes. Using the frictional resistance generated when two moving surfaces are in contact with each other, the kinetic energy and potential energy when the automobile is moving are converted into heat energy, so as to achieve a device that makes the vertical lead car slow down or stop.

The performance of the friction material (brake parts) used on the brake directly affects the braking process, and the main factors affecting its performance are the temperature and temperature rise rate after working. Friction materials should have a high and stable coefficient of friction and good wear resistance.

Friction materials are divided into two categories: metal and non-metal. The former is commonly used in cast iron, steel, bronze and powder metallurgy friction materials, etc., and the latter is leather, rubber, wood and asbestos. The temperature condition and distribution characteristics of the surface of the brake friction pair will directly affect the braking performance and service life of the brake.

The friction brake produces a large amount of friction heat in the work, which can make the working surface of the brake produce local high temperature, and the surface oxidation and even thermal fatigue wear will eventually make the friction brake fail, so it is of great significance to study the influence of temperature on the performance of the friction brake. The friction brake temperature is a very complex problem, involving a wide range of disciplines, which requires the comprehensive application of multiple disciplines, especially the flexible use of computer, mathematics, physics, chemistry and materials science

For the design of brakes and the development of friction materials, the main problem to be solved is to seek a material matching scheme with sufficient heat capacity, sufficient mechanical strength and wear resistance under normal and high temperature conditions.

The friction coefficient of the brake pad is too high or too low will affect the braking performance of the car. Especially when the car needs emergency braking at high speed, the low friction coefficient will cause the braking insensitivity, and the high friction coefficient will cause the tire to lock, causing the rear of the vehicle and skidding, posing a serious threat to safety.

According to the national standard, the brake pads are suitable for the working temperature of 100 350 °C. However, when the temperature reaches 250 degrees, the coefficient of friction of many bad brake pads will drop dramatically, and the brakes will fail completely. In general, according to the SAE standard, the brake pad manufacturer will select the FF rating factor, i.e. the friction rating factor is:

The friction brake is a mechanical part that makes the moving parts in the machine stop or slow down, commonly known as brakes. Using the frictional resistance generated when two moving surfaces are in contact with each other, the kinetic energy and potential energy when the automobile is moving are converted into heat energy, so as to achieve a device that makes the car slow down or stop.

To put it simply, a brake disc is a round disc that rotates with the car when it is moving, and it works together with the brake calipers and brake riser blades. When we step on the noisy pants and brake, we rely on the brake calipers and brake pads to clamp the brake disc to slow down or stop.

What is Brake? Friction pads are actually brake friction pads are the brakes in the machinery before braking early type installation of the position, that is, brake pads and the like, just like when we drive, the inside of the car, the brake emergency recording device is the same.

Brake pads, also known as brake pads, are actually brake pads, in the braking system of automobiles, brake pads are very important safety parts, play a very key role. The brake pad determines the quality of the braking effect and is closely related to the safety of the car, so the daily maintenance of the brake pad is particularly important.

What does it mean that the brake pads are worn.

In the process of using the car, it will often brake, the brake pad will be gradually worn out due to friction, and the braking effect will become worse and worse, if it is not replaced in time, it will eventually lead to the loss of braking effect and affect driving safety. For your driving safety, check and replace your brake pads regularly.

Brake pads also need to be replaced when they are worn to a certain extent to ensure that the braking effect is not affected. Because the wear and tear of the braking system is affected by a variety of factors, it is best to check the most stupid infiltration every 3,000 kilometers or so. For the new brake pads, it needs to go through a certain run-in period in order to effectively maximize the braking role of Wang Xiao.

Under normal circumstances, the life of the brake pad is about 30,000 kilometers, but this value is not absolute, and it is necessary to decide the replacement cycle according to the actual use and personal driving habits, and the most important thing is to develop the habit of regular inspection and timely maintenance.

Brake pads are brake pads.

Brake pads are brake pads, which are actually brake pads. In the braking system of the car, the brake pad is an important safety part, and the brake pad determines the quality of the braking effect, which is closely related to the safety of the car.

The car often brakes during use, the brake pad will be gradually worn out due to friction, and the braking effect will become worse and worse, if it is not replaced in time, it will lead to the loss of braking effect and affect driving safety. Under normal circumstances, the brake pads are replaced about 30,000 kilometers.

Brake pad authenticity identification method:

1. Material: Really: It is made of environmentally friendly organic materials that are wear-resistant and noise-suppressing, and has stability that is not affected by temperature differences. False: The surface of the friction plate is relatively smooth, the friction coefficient is not up to standard, the friction ability is weak when braking, and the braking effect is poor.

2. Welding process:

Really: the friction material is in firm contact with the metal plate, which is not easy to detach, and effectively guarantees the safety of driving. False: The friction material is not in good contact with the metal plate, and there is a possibility of falling off during emergency braking, which threatens driving safety.

The role of brake shoe friction pads:

1. At present, there are two ways to process the brake friction plate, one is to take it off from the car, and fix it on the special fixture for grinding or turning processing, although this mode can improve the processing quality, save man-hours, and is suitable for professional division of labor and flow operations, but due to the limitation of China's current overhaul and maintenance technology, the brake shoes processed in this way often cannot meet the vehicle assembly requirements, thereby affecting the braking efficiency in the early stage of driving;

2. The other way is to process the brake shoe friction plate on the car, because it is positioned and processed from the actual situation, it is more suitable for the assembly requirements of the brake, although it consumes more man-hours, but it is flexible and flexible, and it is convenient for general maintenance plants or workshops to use;

3, the use of the first two ways of processing equipment for self-made, from the whole machine structure can be divided into integral and separate, the latter is the moving cutter head and the feed mechanism is installed on a trolley, and the tool holder and positioning device are fixed on the front axle or rear axle of the car; The former of these institutions are made as a whole mounted on the car.

Answer: The friction plate of the motor brake can be divided into two categories of friction materials according to the function, Yinminxing transmission and braking, and the Chuanfeng uproar system is through the fitting and separation of the motor friction plate in the clutch assembly, and the power is transmitted in the motor to make the motor run.

Question 8: What is the material of the friction pad of the automobile brake For the brake pad, the most important thing is the choice of friction material, which basically determines the braking performance of the brake pad. Friction materials are divided into three basic materials: asbestos, semi-metal, and organic (NAO).

In 1999, China banned the use of asbestos in friction plates, and at present, semi-metal friction materials are commonly used in China, and steel or copper materials are mostly used.

The quality of brake pads is directly related to the reliability of vehicle braking. Brake pads are like candles, silently consuming their lives for our safety.
