The working principle of the brake cylinder braking system

Although it is as easy as anyone can do, compared with accelerating and decelerating, it is a relatively advanced knowledge. Whether it is a track or a street, the braking requirements are absolutely different. Of course, the brake cylinder brake on the parts requirements are also completely different. Some people like a strong sense of hitting the wall, while others like a sense of linear progression. So, let's understand the working principle of the brake cylinder braking system.

Today, we will start with the basic theory of the brake cylinder braking system, introduce the working principle of the brake cylinder braking system, as well as the types and related knowledge we should know.

When we need to slow down or brake, it is very easy to press the brake pedal and the car will slow down and brake naturally. However, have you ever wondered why a ton of cars can be slowed down by a single step that has no strength? The important thing is to slow down under the force of friction until the moving vehicle stops.

In fact, the braking force we commonly speak of is "friction." The so-called brake force is insufficient, in fact, refers to the brake pad and shoe friction brake disc and wheel hub, through this strong friction to reduce the energy of wheel rolling. And of course, there's actually the friction of the tire against the road.

Broadly speaking, the brake of the brake cylinder moves in the opposite direction on the contact surface, that is, the resistance. But the important thing is the pressure between the contact surfaces, which determines the size of the friction force. The principle of the brake caliper is very simple, as long as the pressure is applied, the brake disc will slowly rotate and stop the car with the spinning wheels. That's where the braking force comes from.

In addition to the pressure, the "friction coefficient" is also determined by the different materials (rough friction, temperature, humidity, etc.) to the friction force of the brake. Therefore, in the choice of various grades of brake discs and brake pads, for the brake system can also play an important role.

In addition, the structure of ABS can also be briefly introduced. When the brakes are applied, the friction of the tires causes an effective deceleration action. The reason for this is "static friction", where the coefficient of friction and positive pressure act the most. On the other hand, if the tire is completely locked, it will cling to death. The friction coefficient on the road surface decreases gradually and the friction force becomes smaller. Apply the brakes to the end can not brake. Therefore, HERE, through the intervention of ABS, the locked state is released, and the chopper pressure is applied to separate and lock the tire, on the contrary, can keep the friction of the brake at the highest state.

Actually, a lot of my friends asked me general questions. Whether the brake main pump needs to be replaced after the brake cylinder is replaced with the caliper with more pistons. My answer is also very simple, in fact, measuring the power of the main pump to calculate whether the force is sufficient is a reliable method. What is this brake main pump? Let me tell you a little bit about it. As for the brake main pump of the brake cylinder, in simple terms, the cylinder area is isolated into the "pressure end" and "vacuum end". When the brake is applied, the central link of the booster is driven, and the atmospheric valve of the "pressure end" is opened. At this time, atmospheric pressure instantaneously impinges on the pressure end, producing strong pressure, working on the central diaphragm, driving the master pump of the brake, and using PASCAL's principle to make the caliper work. Is to use this pressure difference to double the force of the foot, through the oil to apply enough force to the caliper, to stop the vehicle.

About the type of brake, brake cylinders are common disc brakes and drum brakes. Compared with disc brake, drum brake has the advantages of small space and good sealing. But the shortcomings are also very obvious, braking force response slow, poor heat dissipation, maintenance trouble and other obvious shortcomings. Therefore, the current market to see the drum brake civilian cars are less and less.
