The secret of the braking method of Flatbed semi trailers

Flatbed semi trailers are large and small, and can pull various different goods. But don't think that it is just a change in size, its braking method is also very particular. If you want to know more about Flatbed semi trailers, you must first understand its braking method. Today, I will tell you about the braking method of Flatbed semi trailers so that you can know more about your trailer.

1. Pneumatic braking

Pneumatic braking is the most commonly used braking method for Flatbed semi trailers. When you step on the brake pedal, the brake valve will open, and the compressed air will run to the brake air chamber through the pipe, and then push the brake pads and brake drums to contact, generating friction, and the car will stop. This method has a simple structure, good braking effect, and convenient maintenance. It is especially suitable for vehicles pulling heavy goods.

2. Hydraulic braking

Hydraulic braking is also useful on some small Flatbed semi trailers. It uses hydraulic oil as power, which is transmitted through hydraulic pumps and pipes to achieve braking. This method has sensitive braking and uniform braking force, but it is not suitable for large vehicles. Some small Flatbed semi trailers that pull light goods may use it.

3. ABS anti-lock braking

ABS is a high-tech braking method. It uses sensors to see how fast the wheels are turning. If a wheel is about to lock, the ECU (electronic control unit) will control the solenoid valve to quickly adjust the braking force of that wheel to prevent it from locking, so that the car can remain stable and will not slip or lose control.

4. Auxiliary braking

In addition to the above main braking methods, Flatbed semi trailers also have some auxiliary braking systems, such as engine braking and exhaust braking. These auxiliary brakes can help reduce the burden on the main braking system when going downhill or pulling heavy goods, making the braking effect better and safer.
