Does anyone know about the car s braking problems acceleration 10

This is due to inertia.

As long as an object is not affected by external forces, the original stationary will always be stationary, while the original moving object will always move in a uniform straight line. The question here is: is inertia a property of an object?

According to Newton's first law of motion, any object has inertia. This property is possessed by all objects, i.e. it has nothing to do with the individual characteristics of the object. Thus, inertia can only be a feature of existence, the manifestation of the environment around the subject under study on the object.

In other words, it is a condition, a constraint, that exists around the object.

When a person is in a car, the car gives people a forward friction force through the contact parts with the human body, such as the buttocks or hands and feet, so the person follows the person forward. People also have the inertia to move forward, but when the car does the braking action, the forward force given by the car is gone, and the person continues to maintain the original forward motion due to the principle of inertia, so the person will continue to move forward, that is, the performance of the "leaning forward" action, but due to the contact between the person and the car, the car will give people a backward friction at this time, so that the person will get rid of the inertia to do the stay action, so the person will not keep moving forward!

You're asking a lot more broadly.

So many models of cars are produced all over the world.

It's impossible to give you a detailed description of each model.

Say what you want.

Acceleration.

Acceleration when the car brakes:

There is a formula for 2as=v 2

Bring in there is s = so the displacement of the car within 5s is.

Acceleration is determined by the frictional resistance of the brakes and the mass of the car. The speed is reduced. When braking, basically the brake pads lock the tires in place. The acceleration at this time is generated by the friction f between the tire and the ground, and f divided by the mass of the car is the acceleration when braking.

When braking, basically the brake pads lock the tires in place.

In this case, the acceleration (or deceleration) is generated by the friction f between the tire and the ground.

f divided by the mass of the car is the acceleration when braking.

The magnitude of f is determined by the coefficient of friction of the tire against the ground and the weight of the car).

How much do you know about the problem of poor braking in cars? Because the adhesion to the ground is too small, the braking torque of the engine is too large, and in the process of vehicle braking, the braking torque is greater than the dynamic friction between the tire and the ground, resulting in the thrust of the vehicle exceeding the ideal sliding rate of the vehicle, resulting in lateral sliding. When the brake is depressed, the slip rate of the wheel is detected.

When a certain value is exceeded, the engine braking torque is quickly processed. When less than a certain slip rate within a certain continuous mileage, the brake torque limit of the engine is withdrawn.

<> ABS needs to receive a braking signal (hard wire or information) when working. Gently pressing the brake may not activate the brake button, causing it to open due to low air pressure. Energy** may clog the wheels (ABS is not activated).

Percentage of engine or engine torque received by ESC from VCUs, based on the historical situation of the past five years (2016-2020), this document analyzes the overall size, the main regional size, the scale of the main business and participation, the scale before the relaxation of the main product classification, the scale of the main downstream applications, etc. , the overall energy ** system of the car over the past few years. The sizing analysis includes sales,**, revenue, and market share.

For any car, the braking system is always the most important factor in ensuring driving safety. As Noem said, braking is used to suppress energy. Especially for car owners who blindly pursue high performance, you can also replace a set of large multi-piston brake calipers to directly improve braking performance.

The principle is also very simple, and the coverage area will be larger and larger. It would be very dangerous to only increase the energy without modifying the braking system.

When a vehicle collides, a large amount of kinetic energy is instantaneously converted into heat energy by the braking system, which is then dispersed across the braking components, wheels, and the road. In addition, if the wheels are not clogged during braking, most of the heat energy will be absorbed by the brake components. If it is not dispersed quickly, it will cause the brake discs and calipers to overheat and lose their original energy.

In addition, when modifying the car, you also need to pay attention to the weight of the brake calipers. It weighs more than twice as much as a cast iron caliper, and the former also has high heat dissipation performance. For example, as part of the unperformed weight, the weight has a direct impact on the handling in the first place.

If the force allows, it is recommended that he replace the high-caliber brakes, after all, it is safe to drive.

<> "Brake fluid, also known as the kinetic fluid, as a functional liquid, it also has a shelf life like engine oil. Generally speaking, the brake fluid needs to be changed once every two years.

Because of the long time in the brake fluid will enter some moisture and air, so that the boiling point of the brake fluid will be reduced, in the emergency braking due to the increase in oil temperature and reduce the braking performance, here is also to remind everyone that the brake fluid can not be mixed. Different brands of brake fluid may react after mixing, generating impurities and air, which affects the braking force.

This sounds the same as the first case, but it's not. The first is the natural deterioration of the brake fluid, while the second is the introduction of moisture and air into the brake fluid due to human error or a harsh environment.

Otherwise, after a long time, a large amount of water vapor will enter the brake fluid, which will seriously affect the physical properties of the brake fluid, and the consequences will be unimaginable when braking suddenly.

Now, with the popularity of technologies such as direct injection and turbocharging, most cars are equipped with independent vacuum booster pumps to pump air from the vacuum booster to create a vacuum.

But sometimes when the engine is under heavy load, such as when the air conditioner is turned on in the summer, the pumping strength of the engine will be weakened. This creates a situation where the vacuum level in the vacuum pump is insufficient. When you brake continuously, the braking force of the first foot is sufficient, and the braking force of the second and third feet will decay.

One foot brake is not effective, but the braking effect is very good when the pedal is pressed several times in a row, generally because the free stroke of the Kai brake pedal is too large or the brake clearance is too large. The free travel of the pedal should be adjusted, and then the brake clearance should be checked, and the brake disassembly repair should be carried out if necessary.

When the brake pedal is pressed, it is not soft or sinking, but the braking effect is poor, which is the fault of the wheel brake, such as the brake shoe with oil or poor contact, the aging and wear of the friction pad, and the uneven wear of the brake drum. The condition of the braking technology should be checked and adjusted and repaired if necessary.
