FAQ:
Q1:What is a ventilation disc?
A1: The full name of the ventilated disc is the ventilated brake disc. Its interior is hollow, and there are many holes on the circumference leading to the center. The centrifugal force during car operation can cause air to circulate in these holes, thus achieving a good heat dissipation effect. Its heat dissipation performance is far superior to that of ordinary brake discs.
Q2:What are the differences between a ventilated disc and a solid disc?
A2: Solid discs are mainly used for the rear wheels, while ventilated discs can be used for all four wheels. The ventilation disc has many process holes, a wide range of friction material options, is lightweight but has a relatively high manufacturing process and price. Ventilated discs have better heat dissipation performance and can dissipate heat through holes, thus having a longer service life. During braking, they can quickly dissipate heat and maintain good braking performance. In contrast, solid discs may have their braking effect affected by the heat generated during braking.
Q3:Why are ventilation discs usually not used on the rear wheels?
A3: For most ordinary front-wheel drive cars, braking mainly relies on the front wheel brake discs, with the rear wheel brakes playing an auxiliary role. The rear wheels have less braking force and generate less heat, and ordinary brake discs are sufficient to handle it. In addition, ventilated discs are expensive. To cut costs, many vehicles do not use ventilated discs on the rear wheels.
Q4:What is the function of the holes on the ventilation tray?
A4: The holes on the ventilation disc are mainly used as ventilation holes to help cool the brake disc, which can accelerate ventilation and heat dissipation, improve braking efficiency, and at the same time, it can also suppress braking noise, reduce weight, clean and exhaust.
Q5:Why is the heat dissipation effect of the ventilation disc better than that of the solid disc?
A5: The ventilated disc has a unique structure. Its interior is hollow and has numerous holes. When the car is in motion, the centrifugal force causes the air to flow through the holes, forming convection, which quickly takes away the heat generated by braking. However, the solid disc does not have such channels for air convection. Its heat dissipation mainly relies on the heat conduction of the disc itself, so its heat dissipation effect is not as good as that of the ventilated disc.
Q6:Is the service life of a ventilation disc longer than that of a solid disc?
A7: Generally speaking, the service life of ventilation discs is longer than that of solid discs. Because the excellent heat dissipation performance of the ventilated disc can reduce the wear and performance decline of the brake disc caused by high temperatures, under normal usage conditions, the ventilated disc can be used for a longer time.
Q8:Will ventilated discs reduce the strength of brake discs?
A8: Yes. The holes on the ventilated disc will to some extent reduce the strength of the brake disc. The more holes there are, the lower the strength will be, and the service life will also be shortened accordingly. Therefore, it is not the case that the more holes a brake disc has, the better. The number and layout of the holes should be reasonably designed under the premise of ensuring sufficient strength.
