What is the stability of the car s braking? How to improve the braking performance of your car

The evaluation index of automobile braking performance stability includes three aspects: braking efficiency, the constancy of braking efficiency, and the directional stability during braking

1. Braking efficiency.

Braking efficiency refers to the ability of the car to quickly reduce its driving speed until it stops, or to maintain a certain speed and park on the ramp when going downhill, which is the most basic evaluation index of braking performance. Generally, it is evaluated by braking deceleration, braking force, braking distance, etc.

1. Braking deceleration.

It refers to the amount of change in the speed of the vehicle per unit time when braking. It reflects the magnitude of the braking force on the ground, which is related to the braking force and adhesion of the brakes.

2. Braking force.

1) Ground braking power.

2) Braking power.

3) The relationship between ground braking force, brake braking force and adhesion.

The greater the ground braking force of the car, the greater the braking deceleration and the shorter the braking distance; The braking force on the ground depends first on the braking force of the brakes, and at the same time is limited by the adhesion conditions on the ground. Therefore, sufficient braking power can only be obtained if the car has sufficient braking power and the ground can provide high adhesion.

3. Braking distance.

It refers to the distance made by the vehicle from the driver's right foot touching the brake pedal to the vehicle stopping when the vehicle is pressed the brake pedal with the specified pedal at the specified speed.

The main factors that affect the braking distance: the time the brake is in action, the maximum braking deceleration (determined by adhesion and brake braking force), and the braking speed. Therefore, timely maintenance of the vehicle can shorten the brake action time and stabilize the braking performance.

The stability of a car's braking refers to the ability of a car to maintain a straight line or drive in a predetermined curve during braking. Brake mistracking and rear axle slippage or loss of steering ability of the front wheels are all braking stability problems.

Car deviation refers to the phenomenon that the car cannot slow down or stop in a straight line when braking, and the car automatically deviates to the left or right.

Sideslip refers to the phenomenon that the wheels of a certain axle slide laterally or the wheels of two axles slide laterally at the same time when the car is braking.

1. Tire adhesion:

Replacing the tires is the most straightforward way to improve braking performance, and low-spec models can consider replacing the tires and wheels of high-spec models, so that you can increase braking capacity with minimal changes. If you're not satisfied, consider switching to wider tires, or choose tires that suit you better and perform better, considering your actual use.

2. Braking strength:

Replace a good set of brake pads.

It can have an immediate effect, but you must pay attention to it when purchasing, many high-performance brake pads are required by the beam stove to have a higher initial working temperature. It should be noted that the coefficient of friction.

The brake pads that are too high are not suitable for street use, and the brakes will become extremely sensitive after modification, which is extremely detrimental to driving comfort.

Change the brake fluid.

The tube is also a cost-effective solution to improve the braking feeling, and many of the original brake hoses are too soft, and the expansion is large when braking, which slows down the flow speed of brake oil and brake pedal.

When you press it, the brake response is slower. A good brake hose hose is wrapped with steel wire, which can reduce deformation and improve brake texture.

If you have wider tires installed, consider replacing them with larger brake discs.

With brake calipers, four pistons or even more than six pistons, but remember to increase the number of pistons, the sub-cylinder needs more brake fluid to push, if necessary, you need to replace the master cylinder, otherwise there will be a phenomenon such as the brake pedal travel becomes longer, and the brake foot feeling will decrease.

3. Weight:

Built-in weights will not only increase fuel consumption but also reduce the handling of the whole car, brakes, etc., for the sake of their own safety, quickly take the time to clean the trunk, braking distance one or two meters more can often decide a lot of things.

Brake system maintenance:

1. Brake pad replacement. Usually the brake warning light on the dashboard is lit as the basis for judging whether the brake shoes should be changed, but this is the final bottom line, and some cars will only light up when the brake shoes have been completely worn out warning lights.

At this time, the metal base of the brake pads and the brake disc are already in a state of iron grinding, and will be rubberized near the rim of the tire.

The edges are shiny iron cuts. Therefore, it is necessary to check whether the brake pads can be used at every time they enter the factory for maintenance, and replace the brake pads that are close to the bottom line of life early.

2. Daily maintenance of the brake system. Clean, high-quality brake fluid.

It is the basic for the safety and braking system to function well. You should buy a good quality brake fluid on the market. All discharged brake fluid should be discarded.

To put it simply, a brake disc is a round disc that rotates with the car when it is moving, and it works together with the brake calipers and brake riser blades. When we step on the noisy pants and brake, we rely on the brake calipers and brake pads to clamp the brake disc to slow down or stop.

I believe everyone knows the importance of brakes for cars, but the brakes of many original cars are relatively poor, and it is difficult to meet the needs of car owners, so people often modify the brakes. Modified brakes have a high cost performance and are one of the items that many car owners often modify.

The two most cost-effective equipment to improve the performance of the car are shock suspension and brakes. Regarding the suspension, most people choose to use BC twisted teeth to improve the handling, which makes people feel that people and vehicles are one; So about the brakes, how do people modify them?

The owner used the Odyssey's large single piston and scribing punch disc on the Swift Spring, although it is also very easy to make, but it is too ordinary on the outside, and the owner also wants to improve the performance of the car, so he began to study the brakes again. This time, the owner intends to use the yellow ultra-thin small six-piston to improve the performance of the car, so can this modified brake effectively improve the performance of the car? Let's take a look at the case of Swift modification yellow brakes.

1. Unpacking. The blue calipers are pretty to be. Precautions for calipers and a family photo.

2. Dismantle, there is also a large single caliper of Odyssey on it.

3. Replace the screws on the hub and install the bridge bracket.

4. Compared with the previous Odyssey 280mm plate, the marking split disc is much better.

5. Install the blue caliper on the scribing split plate, and it is being installed.

6. After installation, the effect comes out, the position of the disc is very accurate, and the brake hose is installed.

1. Tire adhesion:

Replacing tires is the most direct way to improve braking performance, and low-spec models can consider replacing the tires and wheels of high-spec models, so that you can increase braking capacity with minimal changes. If you are not satisfied, you can consider changing to wider tires, or consider your actual use and choose tires that are more suitable for you and have better performance.

2. Braking strength:

Many car owners will feel that their vehicle brakes are soft after buying a car, and they always have no bottom when they need to brake vigorously, if they only need to improve this, there is no need to spend a lot of money to modify the entire braking system, and only a small change before the boring can meet the needs.

Several factors affect the brakes:

1. Vehicle weight: The heavier the vehicle, the greater the force required for braking.

2. Tire adhesion: As the only part of the car that is in contact with the ground, the size of the adhesion determines the different characteristics of handling, acceleration, brake cover, etc., and is also the most critical factor.

3. Braking strength: the greater the braking force, the better the braking performance, but no matter how large the braking force exceeds the tire adhesion, it is also in vain.

Meaning:When the car is braking. Excessive braking force.

If the front or rear wheels are locked, sideslip and mistracking will occur. Then the direction will change. So that the direction is unstable.

If you are blind, you will definitely die. Then the ideal state is that the front wheel is slightly ahead of the rear wheel locked. This direction does not change much.

The direction has been to the right, and the braking performance of the car itself will not turn to the right much because of completeness. The car sometimes has brake deviation, rear axle skidding or front wheels lose steering ability, etc., resulting in the car losing control and leaving the original driving direction, and even crashing into the other vehicle's driving track, ditch, sliding down the hill dangerous situation, which is also the directional stability of the car when braking.

Directional stability refers to the ability of the object to drive according to the trajectory specified by the person in the process of braking the object, that is, the ability of the macro to maintain a straight line or drive according to a predetermined curve, which has an important impact on the safety of vehicles and aircraft. Stability is an extremely important characteristic of the system, and the analysis of the motion stability of the system is an important part of the system and control theory. There are two definitions of system stability:

External stability is characterized by an input-output relationship; Internal stability as represented by state motion under zero input conditions.

Hello dear, improve the reliability of the working brake of the hoist, improve its pressure regulation performance, and replace the original nozzle baffle type pressure regulating device controlled by cross spring with an electro-hydraulic proportional relief valve pressure regulating device. The electro-hydraulic proportional relief valve is composed of a proportional solenoid, a pressure pilot valve, a main valve, and a safety valve, etc., and the force proportional to the input current is generated by the proportional solenoid to act on the core of the pressure pilot valve, changing the size of its throttle hole, so as to control the pressure of the pressure valve inlet. This kind of device has the characteristics of compact structure, stable pressure regulation, good linearity, strong follow-up ability, and excellent dynamic performance.

Hope it can help you, dear <>

1. The directional stability of the car when braking refers to the performance of the car without deviation, side slip and loss of ability to turn and lose direction when braking.

2. Brake deviation refers to the phenomenon that the car automatically deviates to the left or right when the car is driving in a straight line and braking. Most of the deviation is caused by abnormal technical conditions, which can be eliminated through maintenance and adjustment. Sideslip refers to the phenomenon that the wheel of a certain axle or the wheel of two axles slides laterally when the car is braking, and the biggest danger is the sideslip of the rear axle during high-speed braking.

3. There are many factors that affect the stability of the braking direction of the car, and even the wind direction will lead to the instability of the braking direction. Therefore, when studying the braking direction stability of automobiles, the main factors should be identified and solved to improve the braking stability.
