What are the advantages of ventilated brake discs? What is the difference between car brakes, ventil

The ventilated brake disc has an inclined spiral structure in the middle, which will blow a large amount of air into the brake disc when it advances, which can cool down the braking system. Compared with the drum brake of the car, the structure of the disc brake is more conducive to the heat dissipation of the brake, and the detection and maintenance of the brake pad is more convenient, and the use of the brake pad can be directly observed. If it helps, hopefully.

1. Solid brake disc.

A physical brake disc is a metal disc used for braking. This type of brake disc has a simple structure and is cheap. However, the heat dissipation effect is poor, so the thermal braking effect is relatively poor.

2. Ordinary ventilation type.

The normal ventilated type is an improvement on the basis of the physical brake disc. The heat dissipation performance has been enhanced, and the braking effect is more stable, which is currently used in most cars.

3. Perforated brake discs.

The perforated brake disc has better cooling, shortens the braking distance, and has a more stable braking effect, which is generally suitable for high-end cars.

4. Scribing brake discs.

The dust and debris attached to the brake disc can be discharged, and the rainwater can also be discharged when the road surface is wet in rainy days, so that the car will not be affected by excessive rain on the brake disc.

5. Ceramic composite brake disc.

It is made of a mixture of carbon fiber, graphite and silicon, whether it is hot or cold braking, it has better braking performance and longer service life, and is generally used on high-end cars or high-end sports cars.

1. The position of action is different.

Disc brakes: The main position of disc brakes is on the rear wheels.

Ventilated disc brakes: Ventilated discs act on four wheels.

2. The structure material is different.

Ventilated disc brakes have many more process holes than disc brakes. The quality of ventilated disc brakes is lighter than that of disc brakes, but the manufacturing process and ** are more expensive than those of disc brakes.

3. The heat dissipation effect is different.

The heat dissipation performance of ventilated disc brakes is stronger than that of disc brakes, because ventilated disc brakes can improve the heat dissipation effect through the holes in the disc, so the life of ventilated disc brakes is longer than that of disc brakes.

4. The braking effect is different.

Ventilated disc brakes can quickly dissipate heat during the braking process, and the braking effect is also very good.

Disc brakes can affect their braking effect due to the heat brought by the brakes.

5. The maintenance cost is different.

Disc brakes cannot be used for a long time, but they bring lower maintenance costs.

The difference between automobile brakes, ventilated discs and discs is not the same as the heat dissipation effect. Hope.

The difference between disc brakes and ventilated disc brakes is: different styles, different heat dissipation methods, and different applicable models.

First, the style is different.

1. Disc brake: There are several exhaust ports in the center of the brake disc of the disc brake.

2. Ventilated disc brake: Ventilated disc brake has many cavities leading to the center of the circle in the circumference of the brake disc.

Second, the heat dissipation method is different.

1. Disc brake: The disc brake passes through the exhaust port, which can make the heat dissipate quickly.

2. Ventilated disc brake: The centrifugal force generated by the vehicle in the exercise can make the air convection, and the natural wind brought by the driving can achieve the purpose of heat dissipation through the cavity leading to the center of the circle through the ventilated disc brake.

3. The applicable models are different.

1. Disc brake: Disc brake is low in cost and generally used in low-end cars.

2. Ventilated disc brake: The cost of ventilated disc brake is more expensive than that of disc brake, and it is generally used in high-end cars.

The main differences between solid disc brakes, i.e., ordinary disc brakes, and ventilated disc brakes are as follows:

1. Position difference: the main position of the solid disc is on the rear wheel, while the position of the ventilated disc is all four wheels.

2. Structural differences: The choice of friction materials of the ventilation disc is very wide, but there are many more process holes than the solid disc. The mass is lighter than that of a solid disc, but the manufacturing process and ** are more expensive than that of a solid disc.

3. Effect difference: the heat dissipation performance of this ventilation disc is stronger than that of the solid disk, and the ventilation disc can improve the heat dissipation effect through the holes on the disk. The life of the ventilated disc used is also longer than that of the solid disc, and it can be said that the ventilated disc is a kind of improvement of the solid disc.

4. Difference in use: Because the ventilation disc can quickly dissipate the heat in the process of braking, the braking effect is also very good. Solid discs will affect the braking effect due to the heat brought by the brakes, and the higher weight will lead to increased fuel consumption and maintenance costs.

The solid type cannot be used for a long time, but the maintenance cost is much lower.

1. The location is different

Disc type usually refers to the ordinary disc type, that is, the solid disc type, the solid disc is mostly gray iron, the material dissipates heat quickly, and is mostly used for the rear wheel of the car or the front wheel of the micro car; The position of the ventilated disc is that all four wheels can be used, but it is mostly used for the front wheels.

2. The structure is different

The choice of friction material of the ventilated disc is very wide, and there are ventilation holes in the middle of the brake disc, which has many more process holes than the solid disc type; The mass is lighter than that of a solid disc, but the manufacturing process and ** are more expensive than that of a solid disc.

3. Different heat dissipation performance:

The heat dissipation performance of the ventilation disc is stronger than that of the solid disc type, and it can improve the heat dissipation effect through the holes in the disc, and the life of the ventilated disc is also longer than that of the solid disc type, which is an improvement of the solid disc.

4. The braking effect is different

Because the ventilated disc can quickly dissipate the heat during the braking process, the braking effect is also very good.

Solid disc type will affect its braking effect because of the heat brought by the brake, because the weight is greater to bring the increase in fuel consumption, the cost of maintenance is also increased, and can not be used for a long time, but the cost of maintenance is much lower.

The disc brake of the car is divided into two kinds, one is the solid disc brake, the other is the ventilated disc brake, the principle of the brake is the same, but the manufacturing process and braking effect are different.

The brake disc size of the solid disc brake is small, and there is no ventilation hole on the disc, the long-term braking is easy to produce thermal attenuation, and it is easy to produce a short-term brake failure phenomenon after passing the water, you can step on a few feet, there is no big problem. It is relatively cheaper to build, but the braking capacity is much stronger than that of drum brakes.

The size of the brake disc of the ventilated disc brake is larger, and there are regularly arranged ventilation holes on the disc, the long-distance brake thermal attenuation is less, and the brake is sensitive, but the cost is more expensive and the process is more complex.

Generally, medium and high-end cars mostly use the brake system of front solid disc and rear ventilated disc, and only high-end cars, sports cars, and racing cars use four-wheel ventilated disc brakes in order to maintain sufficient braking capacity.

Disc brake pads (discs) are divided into ordinary disc type and ventilated disc type. The ordinary disc type is easier for us to understand, and to put it bluntly, it is solid. Ventilated disc, as the name suggests, has the effect of ventilation, which refers to the centrifugal force generated by the car during the exercise of the air convection to achieve the purpose of heat dissipation, which is determined by the special structure of the disc disc.

Externally, it has many holes in the circumference that lead to the center of the circle, which are made by a special process (slotteded & drilled), so the heat dissipation effect is much better than that of ordinary discs. Due to the relationship between manufacturing process and cost, brake pads with front ventilated discs and rear ordinary discs are generally used in middle and high-end cars. Such as Passat, Vento, Corrado and other cars, some high-end cars use front and rear ventilation discs.

Most of the economy cars use front disc and rear drum brake pads (brake pads), and the front disc used here is generally only an ordinary disc rather than a ventilated disc. It is worth mentioning that the use of ventilated discs in the front wheels is gradually replacing the use of solid discs.

The ventilation plate is good, the weight is light, and the heat dissipation is fast. However, the manufacturing cost is high.

The difference between a solid disc and a ventilated disc is the presence or absence of ventilation holes.

There are generally two types of ventilated disc brakes. One is a hollow disc, which has many cavities leading to the center of the circle at the circumference, so the heat dissipation area is large, and it can make full use of the air flow to dissipate heat, which can effectively reduce the thermal degradation of braking. Since it is hollow, it is lighter in weight than a solid disc of the same size.

Generally, the front wheels of ordinary cars adopt this structure. And, ventilated discs are gradually replacing solid discs.

There is also a hole and groove on the friction surface, which not only increases the heat dissipation area, but also has the function of drainage and impurities. Brake discs of this construction were first used in racing cars, but are now mostly only used on high-performance street cars. Racing cars are basically useless, because of the following two defects:

1.The heat dissipation is uneven, and the hole is easy to crack.

2.It is easy to cause uneven wear of brake pads.

Due to the fact that the worn brake pads are severe and have a short lifespan. Therefore, it is not used by ordinary vehicles.
