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.
