Advantage of BAIYUN Drum Truck Brake Linings

Why Choose BAIYUN Drum Truck Brake Linings

1, Definition of Vehicle Brakes

Automobile brake pad refers to the friction material fixed on the brake drum or brake disc that rotates with the wheel, in which the friction lining and friction lining block bear external pressure and produce friction effect so as to achieve the purpose of vehicle deceleration.

The braking principle is mainly from the friction, using the brake pad and brake disc (drum) and the friction between the tire and the ground, the kinetic energy of the vehicle into the heat after the friction, the car will stop.A good and efficient braking system must be able to provide stable, adequate and controllable braking force, and have good hydraulic transmission and heat dissipation ability, to ensure that the driver from the brake pedal applied force can be fully and effectively transferred to the main pump and sub-pump, and to avoid high heat caused by hydraulic failure and brake recession.There are two major types of brake systems, disc and drum, but apart from the cost advantages, drum brakes are far less efficient than disc brakes.

3, Brake Performance
1). Braking performance: friction coefficient (FF level: 0.35-0.45) braking force: braking force, braking sensitivity
2), wear resistance: wear rate (6-100,000km) wear resistance.(with driving habits, road conditions, climate, brake disc material (different models, brake disc material is different, the weight of the car is different)).
3). Comfort: whether there is noise, whether there is a sense of braking, whether it is smooth.
4). Thermal recession: whether it is heat resistant -- the degree of thermal recession.
5). Shear strength: whether it falls off, whether it is easy to break, the density, whether the density is balanced, whether there are bubbles and gaps.
Other items: whether damage brake disc, whether waterproof - water recession degree, whether environmental protection, and brake disc fitting degree.

4, Factors affecting product quality/performance:
1). Formula and materials:
a. What kind of materials are included in the recipe?Is the ratio of various materials in the formula scientific and reasonable?There are dozens of commonly used materials such as: Arron, copper fiber, ceramic fiber, carbon fiber, synthetic graphite, six titanium potassium acid whisker, powder nitrile, antimony sulfide, etc

b. Purity and quality of materials purchased by the company

2). Components:
The quality of the components used, such as the disc brake sheet's steel back and muffler, also affects the performance and quality of the entire brake pad.

3). Processing technology:
a. Control management and protection of materials and components.
b. Pressing effect of pressing process, pressing pressure, whether it is equal ratio pressing, pressing temperature and duration, etc.
c. Whether the heat treatment temperature and time are appropriate, and whether the grinding process is fine and standardized.
d. Procedures such as sandblasting and polishing, adhesive coating, marking and packaging, and control of semi-finished products and finished products
