Whether the motorcycle brake is better than hub brake or disc brake

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.

Disc brakes have the characteristics of fast heat dissipation, light weight, fast braking and easy adjustment. Especially when high load, the high temperature resistance is good, the braking effect is stable, and it is less affected by external environmental factors, and it is easier for disc brakes to stop the car in a short time than drum brakes when driving in severe cold climate and extreme driving conditions. In addition, some high-performance cars also have many small holes in the brake disc to speed up ventilation and heat dissipation and improve braking efficiency.

However, disc brakes also have their disadvantages, first of all, the manufacturing cost is significantly higher than that of drum brakes, and in addition, they are not as good as drum brakes in terms of durability. And don't look at the disc brake, the size of the brake disc and caliper, as well as the design of the brake pump will directly affect the braking effect of a car, so you can't arbitrarily say which car has a better braking effect just by what structure of brakes a car is equipped with.

When the driver steps on the brake pedal, the sub-cylinder in the drum is driven by the pressure of the oil pipe to push the brake shoe to the brake drum to produce a braking effect. In fact, the drum brake has been used in the automotive industry for a very long time, its biggest advantage is that the structure is simple, the cost is economical, but it can provide a strong braking force, under the same braking conditions, the strength of the drum brake is not weaker than the disc brake, and the vehicle braking system using the drum brake is easier to install and maintain.

However, the disadvantages of the drum brake are also obvious, because the drum brake is sealed, so a large amount of heat energy generated in the braking process is not easy to quickly dissipate, and the heat is an important reason for the decline of braking performance; In addition, the diameter of the brake drum increases slightly when heated, which increases the travel of the brake pedal and reduces the braking effect. Therefore, when a vehicle equipped with drum brakes encounters a mountain road that requires continuous braking for a long time, special attention should be paid to the temperature of the braking system to prevent the performance degradation caused by overheating of the braking system.

In fact, whether it is a disc brake or a drum brake, as long as it is used normally, it can ensure a good braking effect, and there is no obvious superiority or disadvantage. However, according to the use environment, manufacturing cost and driving style, the two types of brakes will show their own advantages and disadvantages.

Disc brake is the use of brake pads and calipers to cooperate with each other, friction when braking will convert kinetic energy into heat energy, the advantage is good effect, fast heat dissipation, sensitive. It can be made into brake pads with a large diameter (for example, the diameter of a high-performance sports car can reach 35 cm or even larger), and generally the car with better power uses disc brakes, but its cost is high, and the cost of accessories is also high. Drum brakes, on the other hand, are hydraulic or air-driven drum brakes to brake the wheels.

The drum brake was applied much earlier, and the truck used this way, the advantage is cheap, and the disadvantage is the advantage of the disc brake.

Due to poor heat dissipation, a large amount of heat can accumulate during braking. Under the influence of high temperature, brake shoes and wheel drums are prone to extremely complex deformation, which is easy to produce brake recession and vibration, resulting in a decrease in braking efficiency.

Of course, if the quality is qualified, the disc type is better, it dissipates heat better, and continuous braking will not affect the braking effect greatly, and the arm is larger, and the force is significant. But considering the cost and use we often use drum brakes on the rear wheels, yes.

The disc brakes of the motorcycle are good.

Because the disc brake has many advantages compared to the drum brake, these advantages slowly let the motorcycle manufacturers eliminate the old drum brake, have assembled the current easier to use disc brake, some positioning slightly high-end models will also be equipped with ABS system on the disc brake.

Advantages of disc brakes

1.Good heat dissipation

The process of braking is to convert the kinetic energy inertia of the vehicle into heat energy on the braking system, so the process of braking each time is accompanied by the temperature increase of the braking system, whether it is disc brake or drum brake, it will become hot in the process of braking, from the structural point of view, the structure of the drum brake is relatively closed, and the brake shoe works in the brake drum, and the brake drum is relatively closed and the air is not circulated, so the heat dissipation performance is not very good.

2.Strong braking effect

The drum brake of the motorcycle is basically a cable-type structure, or the mechanical structure presses the brake shoe to brake; The disc brake is basically a hydraulic structure, composed of the brake upper pump and the lower pump, the brake oil pipe is connected to the upper and lower pumps, and the braking force is applied from the upper pump and the lower pump is applied through the brake oil pipe, so as to complete the braking.

3.Not easily disturbed by debris

As mentioned earlier, the structure of the drum brake is relatively closed, so the debris from the wear of the brake shoe or the fine sand and dust from the outside world are not easy to emit out; The structure of the disc brake is open, in addition to better heat dissipation performance, it can also allow the debris from the brake wear to be washed away by the air, so that the brake system can be kept clean and not easily disturbed by debris.

The strand brake is better.

Drum brake is a brake device that uses 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 via the brake fluid to the brake cylinder pistons of each wheel.

Note: Although there are many types of vehicles, the structure is similar. This should be said to be the credit of standardization, but also the need for large-scale production lines.

With the development of society, the progress of science and technology and the change of demand, the shape of railway vehicles has begun to change, especially the passenger car is no longer the same old face. However, their basic structure has not changed significantly, but the specific parts have a more scientific and advanced structural design.

Generally speaking, the basic structure of the vehicle is composed of five parts: the car body, the undercarriage, the running part, the coupler buffer device and the braking device.

The body is the part of the vehicle that is used to load goods or passengers, and is the basis for the installation and connection of other components of the vehicle. The body of the early vehicles was mainly made of wood, supplemented by steel plates, bow rods, etc. In modern times, the car body is mainly steel structure or light metal structure.

Generally, it is a front disc and a back drum. Many people are not used to the rear disc brake. Generally, large-displacement cars are like this.

Rear dish. It's hard to control. It's easy to flick your tail if you step on it more.

The braking power of disc brakes is faster, more sensitive and more effective, and it looks like it is more classy than drum brakes, but the maintenance is slightly more complicated, and if it needs to be replaced, it is more expensive. Drum brakes are relatively inexpensive, simple and reliable, easy and cheap to maintain, and have enough braking power for the front brakes. Disc brakes are very sensitive because they are not skilled in driving, so they may be relatively dangerous, but in fact, safety mainly depends on the operation of people and not in the disc brake or drum brake, if used improperly, the front drum brake is as dangerous as the brake, and it will also hold the brake.

To be honest, when manufacturing the car, the manufacturer has considered the problem of what kind of brake to use in the back, as we all know that the disc brake effect is good, but it is not easy to control the strength of the brake, if the disc brake is used too hard when stepping on the brake, the car will flick the tail and even have an accident when braking. The drum brake is different, you can choose how much force to use according to the speed of the car to step on the brake, and the drum brake also has an advantage in terms of maintenance, if the disc brake is in the rain or on the muddy road, the brake pads are easy to be worn by the mud and sand, so don't change it, keep the original best !!

First of all; It depends on what kind of car the scooter brakes left and right front.

For example, if there is a foot brake, only the right front brake will cancel the left rear brake, because the brake epidemic has been replaced by the foot brake. If it's a big motorcycle.

15 and 150 and the like, generally only have the right front brake, because our motorcycles also have foot brakes, and the left front brake is canceled.

Small displacement scooters or riding straddles, the speed will not be too fast, and the power and torque of the engine will not be too large, so basically the rear brake is used more. If it is a pedal, then it must be more of the rear brake, because the engine of the pedal is generally at the rear wheel, the weight is concentrated in the rear, the friction between the rear wheel and the ground is also greater, and the braking effect is also the highest when the rear brake is pressed.

When braking on a motorcycle, is it safe to brake in front or back? The average rider understands it wrong!

For us motorcycle enthusiasts, motorcycle brakes are a feature that is often used. However, it is not the same as the braking system of the car, the car is just a foot down and it is over, but the motorcycle is different, its braking method is still very particular, and different motorcycle braking methods are also different, especially there are many types of motorcycles.

In fact, more knowledgeable riders, a look at the configuration of the motorcycle can understand that when the front wheel specification of the general motorcycle is higher than the rear wheel, the linear brake is generally used. In this braking method, when the motorcycle brakes, the wheel pressure of the front wheel is much greater than that of the rear wheel. Now the more popular braking method is pedal linkage brake, which means that when the front wheel brake is used, it can be single-braked, but the rear wheel must be linked to brake, this is because when you brake the rear wheel, the center of gravity of the motorcycle will still move forward, and the rear wheel pressure will become smaller, so the friction will drop very quickly.

Of course, this is only one of the methods, the correct braking method of a motorcycle is also related to the type of braking of your motorcycle and your driving speed, and among them, the small displacement of the motorcycle, the body will be relatively light, so the general use of the rear brake-based, front brake as a supplement to the "routine".

We talked about the small displacement above, and then let's talk about the braking method of the displacement of 250cc and above. If equipped with ABS, it is very easy to say, but not equipped with ABS anti-lock braking system, then riders can use the index finger of the right hand and the middle finger to hook the brake when braking, at a speed of 70km per hour below the front wheel 5 components, rear wheel 5 components to brake, between 70-90km per hour, you can use the front wheel 7 components of force rear wheel 3 components, if the speed reaches 100km per hour, you can no longer brake like this, at this time it is necessary to use the front brake intermittent point brake, Then wait for the speed to drop down and then pinch the front brake to death, and gently press the rear brake, of course, this takes time to practice.

How do you brake a motorcycle without ABS anti-lock braking system? It comes down to braking as much as you want, but there is a premise that a motorcycle without ABS must definitely adopt the braking method of the first seven and the last three. Generally, like the old rider when braking, basically will not use the rear brake, because the center of gravity of the scooter is backward, and the rear brake can be OK in an emergency, and the center of gravity of the straddle bike is forward, and the rear brake is used in an emergency, which is easy to lock the wheels, and may lead to a crash in serious cases.

Therefore, the configuration of the front brake of the motorcycle will be higher than the rear brake, and the small displacement generally uses the front disc brake and the rear drum brake, while the motorcycle with 400cc displacement and above generally uses the front double disc and the rear single disc.

: Why can't you use the rear brake for motorcycle brakes?

Hello, motorcycle brakes should not be said can not use the rear brake, generally speaking, the rear brake is commonly used.

When the motorcycle is moving, the rear brake is used for predictive deceleration and parking, and the front brake is used at the same time for emergency braking, and the front brake is used for emergency braking.

When the motorcycle is driving, do not use the front brake suddenly, so as not to cause the danger of falling to the ground and reversing.

: Why can't you use the rear brake for motorcycle brakes? Do you ride a motorcycle with only the front brake?

This brake is not easy to use and this brake disc must have something to do with it, if the brake disc is worn out more or the brake disc is worn out particularly smooth, this will definitely affect the brake performance. It must have something to do with the brake disc, it needs to be removed and checked, if the wear is relatively large, then it needs to be replaced, if the surface is worn out particularly smooth, then this must also be a problem, and it also needs to be polished and polished. There is also a need to check the brake pad to see if there is a large amount of wear, and it is also necessary to check the position of the brake air pump or brake cable to see if it is loose, and it needs to be checked or adjusted.
