What is ABS car brake explosion proof

Abbreviation for Anti-Lock Brake System Automatic Anti-lock Braking System.

Because wheel locking is a very dangerous thing, the front wheel locking leads to the inability to control the steering, and the rear wheel locking causes the car to flick and skid, in order to avoid these situations, the ABS automatic anti-lock braking system is adopted. The basic principle is to detect the speed of each wheel through a sensor, and when the speed of a wheel is 0 (locked) when braking, the brake of the wheel is terminated by the hydraulic system to get it out of the lock state.

In fact, the wear and tear of the tires is still secondary, once the wheels are locked, the car is very easy to lose control, resulting in dangerous situations. If the front wheels are locked, the most direct thing is to lose the ability to steer, and hitting the steering wheel at this time will not help at all, but can only pray that the car will stop quickly!

If the rear wheels are locked, the steering ability is present, but there is a high probability that the rear wheels will slip sideways, and in severe cases, there will be a tail flick. Once the car skids or flicks, especially at high speeds, the body completely loses control and can only be resigned to fate!

Based on the fact that the wheel locking during braking will make the driver lose control of the car, so that the life safety of the driver and passengers is seriously threatened, how can the wheel lock during braking be effectively solved? This is where ABS (Anti-lock Braking System) was born.

As the name suggests, the anti-lock braking system means that the wheels do not lock when braking.

It is conceivable that when the driver quickly presses the brake pedal during emergency braking, the front wheels will not lock up, and the steering ability will still exist, so it is completely possible to take measures to avoid the danger ahead when braking. If the rear wheels don't lock up, there will be no side slip and tail flick, and control of the body remains in the driver's hands.

After the previous simple analysis, it can be concluded that in fact, the most important function of ABS is not to shorten the braking distance, but to be able to maintain the directional stability of the car when braking as much as possible.

When the anti-lock braking system is in effect, the friction between the wheels and the road surface is rolling friction, which will make full use of the maximum adhesion between the wheels and the road surface for braking, so as to improve braking deceleration and shorten the braking distance, but the most important thing is to ensure the directional stability of the car.

When ABS works, it is equivalent to a very high frequency of point brake, so in an emergency to press the brake pedal, you will definitely feel the brake pedal is shaking, and at the same time, you will hear the "click" sound from the brake master cylinder, which is ABS is working normally. Since the brake master cylinder is constantly adjusting the brake pressure, there is a continuous feedback force on the brake pedal. Therefore, in this case, it is necessary to "unwaveringly" press the brake pedal and at the same time take active measures to avoid danger.

In short, ABS is only an auxiliary safety system, and its role is very limited, so it is important not to rely on these systems 100%, only safe driving is the most important thing.

It is the technology of point brake, so that there will be no accidents due to tire locking and the car will not be uncontrolled.

abs" translates to "anti-lock braking system" in ChineseIt is an automotive safety control system with the advantages of anti-slip and anti-lock. ABS is an improved technology based on conventional braking devices, which can be divided into mechanical and electronic types.

A large number of anti-lock braking systems are installed on modern automobiles, ABS has the braking function of the ordinary braking system, and can prevent the wheels from locking, so that the car can still steer in the braking state, ensure the stability of the braking direction of the car, prevent the occurrence of side slip and deviation, is the most advanced braking device on the car at present, the best braking effect.

In the past, when consumers bought cars, they all regarded the presence or absence of ABS as an important indicator. With the development of technology, at present, the vast majority of cars in China have ABS as a standard configuration. However, many drivers are not very clear about the understanding of ABS and how to use it correctly, and there are even some misunderstandings about ABS.

Some drivers think that ABS is a device to shorten the braking distance, and the braking distance of a vehicle equipped with ABS on any road is definitely shorter than that of a vehicle equipped with ABS, and some people even mistakenly believe that the braking distance on ice and snow roads can be comparable to the braking distance on asphalt roads; There are also some drivers who believe that as long as they are equipped with ABS, they will not lose control of their vehicles even if they are driving at high speeds in rain or on snow and ice. ABS is not the limit of dramatically raising the physical performance of a car, as some people think. Strictly speaking, the function of ABS is mainly within the physical limit of performance, to ensure the handling and stability of the vehicle itself when braking.

At the same time, when accelerating, it can also prevent the pure slippage of the tire, which improves the acceleration performance and operation stability.

The role of ABS system: Antilock brake system (antilock brake system) is abbreviated as ABS. The function is to automatically control the braking force of the brake when the car is braking, so that the wheels are not locked and are in a state of rolling and slipping (the slip rate is about 20%), so as to ensure that the adhesion between the wheels and the ground is at the maximum.

To put it simply, the ABS system will only work when the vehicle needs to brake suddenly, which is to switch without listening to the zero boundary point of tire sliding and rolling, which can effectively shorten the braking distance and prevent the vehicle from sliding when braking suddenly.

This system plays a great role in driving safety starting, so the current vehicle ABS must be equipped.

ABS stands for: Brake Anti-lock Braking System. Its function is to automatically control the braking force of the braking system when the car is braking, so that the wheels are not locked, so that the wheels are in a state of rolling and slipping, so as to ensure that the adhesion between the wheels and the ground is at the maximum.

It is possible to shorten the braking distance of the brakes. ABS usually consists of wheel speed sensors, brake pressure regulators, ABS electronic control units and ABS warning lights. When the system fails, the ABS fault light of the dashboard will be lit to remind the driver to drive carefully and check and repair as soon as possible.

Let's take a look at what are the common reasons for ABS fault lights to light up and how to eliminate them.

1. ABS wheel speed sensor is damaged or dirty. The sensor needs to be cleaned or replaced.

2. The ABS signal wheel is damaged or dirty. Bearings need to be cleaned or replaced.

3. The ABS line is broken due to external force or the sensor plug is connected to the water. Repair of the wires as well as plug connections is required.

4. The fault lamp is lit due to the damage of the ABS control unit. The control unit needs to be replaced.

5. The power supply voltage is unstable, and ABS cannot work normally, resulting in the fault light being lit. The vehicle's power supply system needs to be checked.

6. The four-wheel alignment is incorrect, and the speed and direction angle of the four wheels of the vehicle are different, which causes the ABS light to be lit. Wheel alignment is required, and damaged parts need to be replaced if necessary.

If the ABS lamp is lit, it is recommended to go to a professional maintenance company for maintenance as soon as possible.

When the wheels are braked, the front wheels are locked, the car will lose the ability to steer, if the rear wheels are locked, it will cause the rear wheels to deviate or slip sideways, ABS can prevent the vehicle from locking up, help you control the control of the car when braking, so that you can avoid obstacles by steering, so that you can improve driving safety.

What exactly is the ABS anti-lock braking system used for?

Prevents sideslip when braking.

The brakes of ABS are riot-proof, while ordinary brakes will die violently if they are pressed too tightly.

1. Release the brake once before the vehicle completely stops: If the purpose of our brake is to stop the vehicle, we will step on the brake until the vehicle stops driving in an instant, and the spine grip technique is to release the brake once before the vehicle completely stops, and then tap the brake until the vehicle stops driving.

2. Press the brake pedal hard during emergency braking: some vehicles do not have ABS devices, so it is not recommended to step on the brakes with all your strength at one time, but to step on the brakes twice separately to prevent tail flicking and direction locking after the wheels are locked. The ABS system is now standard on the vehicle, so in the event of an emergency, be sure to press the brake pedal with all your might.

3. Brakes on dirt roads or floating sand roads: This is still dangerous not only on rural roads, but also on urban asphalt roads, due to urban construction and other places on both sides of the road, some floating soil or sand particles will be piled up, at this time, Ye did not advise you to be cautious in the operation of emergency brakes.
