Are ventilated brake discs hollow? Is there a difference between disc brakes and ventilated disc bra

The ventilated disc is a hollow disc. Generally speaking, the disc type is solid. Ventilated disc type heat dissipation is better, whereas disc type heat dissipation is slower. Their differences are as follows:

First of all, these two brakes belong to disc brakes, but the ventilated disc punches holes in the brake disc to make the brake disc cool down more quickly, and is generally used in sports cars or racing cars. Because the process is more cumbersome than disc brakes, the cost will go up, and family cars do not need ordinary brakes, and the brake discs will not often be in a high-heat working state, so to save costs, just use ordinary disc brakes.

Disc brakes work in a similar way to regular bikes – the brake pads on the calipers interact with the brake discs linked to the wheels when braking until the wheels stop turning.

The ventilated discs are perforated in the brake discs to help dissipate heat by using the natural wind brought by driving.

Yes, as the name suggests, the ventilated brake disc has the effect of ventilation, their main difference is that the ventilated disc has many holes leading to the center of the circle in the circumference, these holes are manufactured by a special process, the ventilated disc can make full use of the flowing air for the braking system heat dissipation, which can effectively reduce the thermal decline of the brake, so it is much better than the ordinary disc heat dissipation effect. However, the manufacturing process of the ventilated disc type is much more complicated, and it is relatively expensive.

However, the manufacturing process of the ventilated disc type is much more complicated, and it is relatively expensive.

This kind of ventilated disc is more common in high-end cars, it can make full use of the flowing air for braking system heat dissipation, which can effectively reduce the thermal degradation of braking, so it is much better than ordinary disc heat dissipation.

In order to achieve a better braking coefficient, as well as to prevent thermal decay and improve the service life of the friction block, air-cooled brake discs with excellent cooling performance are generally used. In some cases, air-cooled discs can reduce temperature rise by 20% to 30%. Solid brake discs, on the other hand, are mainly used on the rear wheels.

There are scientific calculations in the selection of materials, sizes and shapes to achieve the best results, I hope to help you.

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.

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.

Disc brakes, also known as disc brakes, are divided into two types: disc and ventilated disc. The size of the brake disc of ventilated disc brake is larger, and there are regularly arranged ventilation holes on the disc, so that the thermal attenuation of long-distance braking is less and the brake is sensitive, but the cost is more expensive.

The cost of drum brake is low, the braking effect is good, but the heat dissipation is slow, so large trucks generally use drum brakes, disc brakes have high cost, and fast heat dissipation is generally used for small cars.

There are two types of disc brakes for automobiles, one is solid disc brakes and the other is ventilated disc brakes. The principle of the brakes is the same, but the manufacturing process and the 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 brakes and drum brakes are the two basic forms of vehicle braking. Regardless of whether it is a disc brake or a drum brake, it is necessary to test the ventilation and heat dissipation, and the ventilation disc brake should increase the ventilation energy in some form, and then coined such a word.

1. Disc brake discs are divided into ordinary disc type and ventilated disc type. The ordinary disc type is relatively easy to understand, that is, it is solid. As the name suggests, the ventilation disc has the effect of ventilation, the main difference is that the ventilation disc has many holes leading to the center of the circle in the circumference, these holes are manufactured by a special process, the ventilation disc can make full use of the flowing air for braking system heat dissipation, which can effectively reduce the thermal decline of braking, so it is much better than the ordinary disc heat dissipation effect.

2. The difference between automobile ventilation disc and solid disc:

1) Position difference: The position of the solid disc is mainly used to guess the resistance branch on the rear wheel, while the position of the ventilated disc is four wheels. Spike Min.

2) Structural differences: The choice of friction materials of the ventilated 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 piece of ventilation disc is stronger than that of solid disk, and the ventilation disc can improve the heat dissipation effect through the holes in 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 ventilated 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.
