Although driving a car and stepping on the accelerator is as simple as anyone can do, it is a more advanced knowledge compared to acceleration and deceleration. Whether it is a racetrack or a general street, the requirements for brakes are absolutely different. Of course, the requirements for parts of Rodless Cylinder brakes are also completely different. Some people like a strong sense of hitting the wall, while others like a linear progressive feeling. So, let's learn about the working principle of the rodless cylinder brake system together!
Today, we will start with the basic theory of the rodless cylinder brake system, introduce the working principle of the rodless cylinder brake system, and the types and related knowledge we should know.
When we need to slow down or brake, it is very easy to step on the brake pedal, and the car will naturally slow down and brake. However, have car friends ever thought about why using a step without any effort can make tons of cars slow down and brake? In fact, the important thing is to slow down under the action of "friction" until the moving vehicle stops.
In fact, the braking force we talk about in daily life is "friction". The so-called insufficient braking force actually refers to the friction between the brake pads and the shoe and the brake disc and the wheel hub, and the energy of the wheel rolling is reduced through this strong friction. Of course, there is actually the friction of the tire on the road surface.
In a broad sense, the brake of the rodless cylinder moves in the opposite direction on the contact surface, that is, resistance, but what is important is the pressure between the contact surfaces, which determines the magnitude of the friction. The principle of the brake caliper is very simple. As long as pressure is applied, the brake disc will slowly rotate and stop the car together with the rotating wheel. This is the source of the braking force.
In addition to the pressure it bears, the "friction coefficient" also determines the strength of the friction on the brake due to different materials (roughness, temperature, humidity, etc.). Therefore, when choosing various grades of brake discs and brake pads, it can also play an important role in the braking system.
In addition, the structure of ABS can be briefly introduced. When the brakes are applied, the friction of the tires will cause effective deceleration. The reason is "static friction", and the friction coefficient and positive pressure have the greatest effect. On the other hand, if the tires are completely locked and immobile, they will be stuck. The friction coefficient against the road surface gradually decreases, and the friction becomes smaller. You can't brake urgently even if you apply the brakes to the end. Therefore, here, through the intervention of ABS, the locked state is released, and the chopper-like pressure is applied to separate and lock the tires, which can keep the friction of the brakes at the highest state.
In fact, many friends asked me a general question. After the rodless cylinder replaces the caliper with a large number of pistons, do I need to replace the brake master pump? My answer is actually very simple. In fact, measuring the power of the master pump to calculate whether the force is sufficient is a reliable method. What is this brake master pump? Let me briefly introduce it. Regarding the brake master pump of the rodless cylinder, in simple terms, it is to isolate the cylinder area into the "pressure end" and the "vacuum end". When the brake is stepped on, the central connecting rod of the booster begins to drive, and the atmospheric valve of the "pressure end" opens. At this time, the atmospheric pressure instantly hits the pressure end, generating a strong pressure, working on the central diaphragm, driving the master pump of the brake, and using the Pascal principle to make the caliper work. It is to use this pressure difference to double the force of the foot, and apply enough force to the caliper through the oil to stop the vehicle.
Regarding the types of brakes, the most common types of rodless cylinders are disc brakes and drum brakes. Compared with disc brakes, drum brakes have the advantages of small space occupation and good sealing. But the disadvantages are also very obvious, such as slow braking force response, poor heat dissipation, and troublesome maintenance. Therefore, there are fewer and fewer civilian cars with drum brakes on the market.
The above is the working principle of the rodless cylinder brake system. If you need to know more, please feel free to contact us!
