ABS is several channels, ABS is classified according to the number of control channels type three

As far as I understand, the ABS pump is a 4-channel tubing.

Nowadays, the vast majority of cars have long taken ABS (brake anti-lock braking system) as a standard configuration, but to say that they really understand the main functions of ABS, know what ABS can do, there are not many such people, so there are some misunderstandings about ABS.

Friends who have driven a car without ABS know that if you press the brake pedal to the end in an emergency, you can hear a squealing of tires, so two black tire marks are left on the road, which is left by the sliding friction with the road surface because the wheels cannot rotate (the technical term is called "wheel locking").

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.

All of the cars with ABS in production today are four-aisle, and most of them are ABS systems from Bosch Bosch in Germany.

Pacific Automobile Network] The front and rear wheels are equipped with ABS, which is called dual-channel Chinese translated as anti-lock brake system, which is a sock guess with anti-skid, anti-lock and other characteristics of the automotive safety control system. ABS is an improved technology based on conventional braking devices, which can be divided into mechanical and electronic types.

The full name of ABS is anti-deadlock brake system (anti-lockingbreaking system), which was invented by the famous German company BOSCH, and the most advanced version is already the tenth generation, which is lighter than the previous version, smaller in size, and has better braking ability, so readers can pay attention to it when buying a car, the same ABS, there are also differences between brands and versions.

When the motorcycle brakes, it relies on the braking device on the axle to reduce the rotation of the wheel belt, but during the emergency braking, the braking force is too large to make the wheel belt completely stop rotating, which is called deadlock, and the tire becomes oiled like a complete loss of grip, and the vehicle will lose control and skid, resulting in more serious accidents.

The ABS system is activated by the wheel speed sensor, when the wheel speed is zero when braking, the system will intervene to release the caliper within half a second to restore the wheel rotation, and then repeatedly release and brake at a frequency of 6 50 times per second, so as to achieve effective deceleration without letting the tire lock up.

The ABS system can only be used on the disc brake device, and if the drum brake with weaker braking force is used, there will be no ABS option.

ABS is classified according to the number of control channels: () formula; Three-channel type; Two links are only simple and simple; A faction of channel style.

Correct answer: Four-channel; Dusty mountain He four-channel type.
