From the recipe technology
Semi-metal, less metal, asbestos, ceramic.
With the rapid development of modern technology, like the components of other brake systems, the brake pads themselves have been constantly developing and changing in recent years.
In the conventional manufacturing process, the friction material used on the brake pad is a mixture of a plurality of binders or additives, and fibers are added thereto to increase the strength and provide reinforcement. Brake pad manufacturers are often tight-lipped on the publication of materials, especially new formulations. Of course, some ingredients such as mica, silica, rubber fragments are public. The final effect of brake pad braking, wear resistance, temperature resistance and other properties will depend on the relative proportions between the different components.
(1) According to the role of the brake system
The brake system can be divided into the service brake system, the parking brake system, the emergency brake system and the auxiliary brake system. A brake system for reducing the speed or even stopping a moving car is called a service brake system; a brake system for parking a stopped vehicle in place is called a parking brake system; In the case of failure of the service brake system, the brake system that ensures that the vehicle can still achieve deceleration or stop is called the emergency brake system; during the driving process, the auxiliary service brake system reduces the speed or keeps the speed stable, but cannot emergency the vehicle. The brake system that is stopped is called the auxiliary brake system. In each of the above brake systems, the service brake system and the parking brake system are required for each vehicle.
(2) Operating energy by brake
The brake system can be divided into a human brake system, a dynamic brake system and a servo brake system. The braking system that uses the driver's body as the sole braking energy is called the human braking system; the system that is completely braked by the potential energy of the air or hydraulic form converted from the power of the engine is called the dynamic braking system; The brake system that brakes manpower and engine power is called a servo brake system or a power brake system.
(3) According to the transmission mode of braking energy
Braking systems can be divided into mechanical, hydraulic, pneumatic, electromagnetic and so on. At the same time, two types of braking systems that use the uploading energy mode are called combined braking systems.
