Introduction: Introduction to Automotive Brake Pads and Braking Principles
The current development of the automotive industry is getting faster and faster, and I believe the main reason is still the need for a larger market. Many friends have cars at home, so everyone must know what brake pads are, but many friends only know. I don't know any deeper knowledge about brake pads, but there are some editors here! Today, the editor will introduce car brake pads to you.
Automotive brake pads: Automotive brake pads
Car brake pads, also known as car brake pads, refer to friction materials fixed to the brake drum or brake disc that rotates with the wheels. The friction lining and pads bear external pressure, producing friction and achieving the purpose of vehicle deceleration.
Automobile brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. Steel plates need to be coated to prevent rust. During the coating process, SMT-4 furnace temperature tracker is used to detect the temperature distribution during the coating process to ensure quality.
Automotive brake pads: braking principles
The working principle of braking mainly comes from friction, which uses the friction between the brake pads and the brake discs (drums), as well as the friction between the tires and the ground, to convert the kinetic energy of the vehicle's movement into the heat energy after friction, and stop the vehicle. A good and efficient braking system must be able to provide stable, sufficient, and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities to ensure that the force applied by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder and various slave cylinders, and to avoid hydraulic failure and brake recession caused by high heat. The braking systems on cars can be divided into two categories: disc and drum brakes, but apart from cost advantages, drum brakes are far less efficient than disc brakes.
friction
Friction "refers to the resistance of motion between the contact surfaces of two relatively moving objects. The magnitude of friction force (F) is related to the coefficient of friction（ μ） The product of the normal pressure (N) in the vertical direction on the frictional force surface is directly proportional, expressed in physical formula as: F= μ N. For the braking system:（ μ) It refers to the friction coefficient between the brake pad and the brake disc, and N is the force exerted by the brake caliper piston on the brake pad (Pedial Force). The greater the friction coefficient, the greater the friction force generated. However, the friction coefficient between the brake pads and the disc will vary due to the high heat generated after friction, which means the friction coefficient（ μ） It changes with temperature, and each type of brake pad has different friction coefficient variation curves due to different materials. Therefore, different brake pads will have different optimal working temperatures and applicable working temperature ranges, which is something that everyone must know when choosing brake pads.
Transmission of braking force
The force exerted by the brake caliper piston on the brake pads is called the Pedal Force. The force exerted by the driver on the brake pedal is amplified by the lever of the pedal mechanism, and then amplified by the power boost using the principle of vacuum pressure difference to push the brake master cylinder. The hydraulic pressure generated by the brake master cylinder utilizes the incompressible power transmission effect of the liquid, which is transmitted to each slave cylinder through the brake oil pipe. The pressure is amplified using the "Pascal principle" to push the piston of the slave cylinder against the brake
