Brake knowledge

Automobile brakes are the braking devices of automobiles. Almost all brakes used in automobiles are friction type, which can be divided into two categories: drum type and disc type. The rotating element in the friction pair of the drum brake is the brake drum, and its working surface is a cylindrical surface; the rotating element of the disc brake is the rotating brake disc, and the end face is the working surface.
Automobile brakes are components that generate a force (braking force) that hinders the movement or tendency of a vehicle to move, including devices in auxiliary braking systems.
Concept and role
Drum brakes are divided into: two-way self-energizing shoe brakes, double leading shoe brakes, leading follower shoe brakes, and double follower shoe brakes according to their different structures. The braking efficiency decreases in turn, the lowest is the disc brake; but the stability of the braking efficiency increases in turn, and the disc brake is the highest. It is for this reason that disc brakes are commonly used. However, in order to improve its braking efficiency, it is necessary to add a brake booster system, which makes the cost higher, so low-end cars generally still use the front disc and rear drum type.
The equipment used to increase the friction coefficient between the tire and the ground is mainly divided into drum type and disc type, which is also used for parking. Braking technology is great, and the instant braking force is not large enough for the drum type, but it can maintain a relatively good braking effect after heating, and the advanced disc brake has 6 brake pumps, which can do a good braking comparison. , so modern cars all use disc brakes.
Automobile brake related - brake fluid
Brake fluid, also known as brake fluid or mineral oil brake fluid, is a brake fluid made of refined diesel fractions with thickeners and antioxidants, including mineral oil brake fluid, alcohol-based brake fluid and synthetic brake fluid. types. Among them, the alcohol type has two grades of No. 1 and No. 3; the mineral oil type has two grades of No. 10 and No. 15, and these two varieties have been eliminated. Synthetic brake oil is mainly used, and synthetic brake oil has three types: alcohol ether type, ester type and silicone oil type, but the most used are alcohol ether type and ester type.
Characteristics of brake fluid
The requirements for brake oil have good viscosity-temperature properties, can work at wider and lower temperatures, and have good oxidation stability, anti-foaming, anti-rubber expansion, and rust resistance. Brake oil is an important product related to traffic safety. High-quality brake oil not only ensures that the vehicle is not damaged, but also ensures the personal safety of drivers and passengers in emergency situations, while poor-quality brake oil is called "traffic killer". The two most important indicators of brake fluid are high temperature resistance to air resistance and kinematic viscosity. The high temperature resistance to gas resistance includes two indicators: the equilibrium reflux boiling point and the wet boiling point, which respectively control the high temperature boiling point of the brake oil and the wet boiling point after water infiltration. The braking force of the car is transmitted through the brake oil, so the presence of air resistance in the brake oil will cause the brake force transmission to lag or even fail. Kinematic viscosity is a requirement for brake fluid to have suitable viscosity under high temperature or low temperature climate conditions. It specifies the viscosity of brake oil at -40℃, 50℃ and 100℃. Failure to meet the requirements will lead to brake system wear or poor transmission.
