Is it better to have drum or disc brakes? Which is better, drum brake or disc brake

We all know that there are two ways to brake on a car, disc brake and drum brake. So is it better to have disc brakes or drum brakes for cars?

Disc brakes are more effective than disc brakes compared to drum brakes, but they are slightly less stable.

Drum brake is to install a brake drum at the tire brake, it rotates at the same speed as the tire, the brake pad will actively open when braking, and the inner surface of the brake drum is violently rubbed to produce braking force to achieve the effect of braking. There are many advantages, first of all, the installation cost is small, so many car companies will use it, and the braking capacity is much stronger than the disc brake, which can complete the braking in a short time.

Disc brake is the brake fluid will push the brake block, let it clamp the brake disc to produce the effect of braking, the advantage is that the heat dissipation speed is fast, the brake sensitivity is high, but the braking force is not as strong as the drum brake, if you want to increase the braking force, you need to increase the diameter of the brake disc.

Because of the drum brake, the safety performance will be a little higher, and the configuration of the car will be a little higher, so it is better for people to choose the drum brake when they choose.

Disc brakes are basically superior to drum brakes in every way. However, drum brakes have a lower level of manufacturing technology and are the first to be used in the brake system, so the manufacturing cost is lower than that of disc brakes.

Disc brakes are also called disc brakes, which are divided into two types: disc and ventilated disc. It is composed of brake discs, friction pads, brake master cylinders, sub-cylinders, brake calipers and oil pipes. The brake disc is generally made of a metal composite material, which is fixed to the wheel and rotates with the wheel.

The cylinder is fixed on the bottom plate of the brake, and the friction plates on the brake caliper are installed on both sides of the brake disc respectively, and the piston of the cylinder is driven by the hydraulic action of the oil pipe to push the friction plate to the brake disc to produce friction braking, and the action is like clamping the rotating plate with pliers, so that the tire stops quickly.

There is no absolute good or bad for disc brakes and drum brakes, but because disc brakes have a more obvious braking effect, they have become a mainstream braking system.

Disc brakes, also known as disc brakes, are driven by a hydraulic pump to push the brake calipers and clamp the brake pads to generate friction, so as to achieve the braking effect.

Advantages and disadvantages of disc brakes:

The disc brake is an external braking system, with good ventilation and heat dissipation, linear braking, good control, and not easy to lock; The disadvantage is that no matter how hard you increase the braking, you can't reach the high braking force of the drum brake self-locking.

Drum brake introduction:

Drum brake, very simple and crude, by the brake plate, brake cylinder, brake shoes and other related connecting rods, springs, pins, brake drums. It is to push the piston hydraulically to make the brake shoes on both sides close to the inner wall of the wheel to achieve the effect of braking, and at this time the wheel rolls forward, and the forward rolling force will react on the brake drum to amplify the braking force. To put it bluntly, the brake pads and the wheel hub rub against each other to slow down.

Advantages and disadvantages of drum brakes:

The cost of drum brakes is low, and the braking force is large, and it can be braked in time. The disadvantage is that the heat dissipation effect is poor, the thermal attenuation is serious, it is not suitable for high-frequency braking, it is not linear, it is difficult to control, and the response is relatively slow.

Although the braking strength of the drum brake is not weaker than the disc brake, the disc brake will be used for family cars that do not need large braking force, or the configuration of the front disc and the rear drum; And for large trucks, the absolute braking force of drum brakes is irreplaceable!

There is no absolute good or bad for motorcycle disc brakes and drum brakes, but because the braking effect of disc brakes is more obvious, it has become a mainstream braking system.

Although the motorcycle disc brake is also a mechanical structure, because of the intervention of hydraulic oil in the process of force transmission, the instantaneous braking effect will be significantly better than that of the drum brake, and the whole control process will be lighter.

The principle of drum brakes.

To put it simply, drum brakes are brake devices that use the static brake pads in the brake drum to rub the brake drum that rotates with the wheels to generate friction and reduce the rotation speed of the wheels.

When the brake pedal is pressed, the force applied by the foot causes the piston in the brake master cylinder to push the brake fluid forward and create pressure in the oil circuit. The pressure is transmitted to the piston of the brake cylinder of each wheel through the brake oil, and the piston of the brake cylinder pushes the brake pad outward, so that the brake pad and the inner surface of the brake drum rub, and produces enough friction force to reduce the speed of the wheel, so as to achieve the purpose of braking.

Hello! This must be a good disc brake, first of all, the disc brake has good heat dissipation, the brake comes quickly, the vehicle is not easy to brake after being parked for a long time, and the drum brake does not have this advantage! Look at the current car configuration, as long as it is not too low, it is standard disc brake!

Disc brake and drum brake have their own advantages, disc brake, good heat dissipation, slightly longer life, beautiful, but the braking force is not as good as the drum brake, and the maintenance cost is slightly more expensive; Drum brake, braking force is larger, maintenance cost is low, parking brake design is more convenient, but heat dissipation is not good; Nowadays, many cars use 4-wheel disc brakes, and the parking brakes of some of them use disc with drums, generally there is a small drum in the center of the rear wheel disc brake. Whether it is a disc brake or a drum brake, it can meet the requirements of braking, and with the continuous maturity of technology, the application of disc brake will be more and more.

Of course, the disc brake is better, compared with the drum brake, the braking and heat dissipation of the disc brake are stronger than the drum brake. Moreover, the disc brake does not need to adjust the brake, and the brake clearance is automatically adjusted.

We all know that there are two ways to brake on a car, disc brake and drum brake. So is it better to have disc brakes or drum brakes for cars?

Is it better to have disc or drum brakes for cars?

Drum brakes are better.

From the analysis of the braking force of the vehicle, the drum brake is better than the disc brake, the braking torque of the drum brake is greater than the disc brake, and the drum brake is supported at both ends through the brake shoe on the structure, which is similar to something like a lever and plays a good role in balancing. The disc brake is equivalent to the friction formed by the clamp to achieve the effect of braking, and the braking force is much worse than the drum brake.

The difference between drum brakes and disc brakes

1. The working principle is different.

The basic working principle of the disc brake is to clamp the brake disc with a stationary brake disc, which then causes a lot of sliding friction and reduces the speed.

The basic working principle of drum brakes is to make the brake system bulge and the car brake pads expand and the brake system drum causes a lot of friction, which in turn reduces the speed.

2. The composition is different.

The disc brake design is a bit like a disc, so it is also called a disc brake, which is mainly composed of a brake disc and a brake caliper.

The drum brake is composed of a rotating part, a fixed part, a pushing part and a precise positioning adjustment device.

3. The advantages are different.

The braking force of the drum brake is relatively large, and the car can be braked in time in case of emergency, which can effectively avoid accidents. Due to the large inertia of large trucks, the requirements for braking strength are relatively high, so the application of drum brakes in large trucks has always been irreplaceable.

The disc brake is an external braking system, with good heat dissipation and easy control, which can be used for high-frequency point brake and ABS point brake.

Disc brakes are better than drum brakes, with larger disc diameters as much as possible, more pistons on calipers, and less weight on their own.

Drum brake shoes are divided into collar shoes and slave shoes, and it is the collar shoes that can automatically increase the force. There are two brake shoes on one wheel. It is generally in the form of collar hooves, but there are also double collar hooves or double hooves.

Sometimes the brakes will make a chirping sound, that is, the sound of the collar shoes, although the braking force is large, but it will damage the brake shoes.

Drum brakes also have their own advantages, in addition to the low cost, under the same diameter conditions, the absolute braking force of the drum brake is greater than that of the disc brake, and the drum brake can increase the braking force with the help of the wheel forward rotation. Of course, drum brakes are more likely to lock up, and thermal decay is faster.

Summary. Pro, and the disc brake is equivalent to the clamp, which makes the brake formed by the friction between the two much worse than the drum brake in terms of braking force. However, from the analysis of comprehensive performance, the braking torque of the drum brake is worse than that of the disc brake, and the drum brake is in a sealed state, which is easy to <>heat up when the vehicle is in use
