How Do Air Brakes Work on a Tractor Trailer
Introduction
Air brakes are a crucial component of tractor trailers, allowing them to safely stop and control their speed while on the road. Understanding how air brakes work is essential for both truck drivers and anyone sharing the road with these large vehicles. In this article, we will explore the inner workings of air brakes on a tractor trailer.
What are Air Brakes?
Air brakes are a type of braking system that uses compressed air to operate. They are commonly found on heavy-duty vehicles such as tractor trailers, buses, and commercial trucks. Air brakes work by using air pressure to apply the brakes when the driver steps on the brake pedal.
How do Air Brakes Work on a Tractor Trailer?
Air brakes on a tractor trailer work by using a series of components to control the flow of compressed air and apply the brakes when needed. Here is a breakdown of how air brakes work on a tractor trailer:
Air Compressor:
The air compressor is responsible for compressing air and storing it in the air tanks on the tractor trailer. This compressed air is used to power the braking system.
Air Tanks:
The air tanks store the compressed air from the air compressor. These tanks hold a reserve of air that can be used to apply the brakes in case of an emergency.
Brake Pedal:
When the driver steps on the brake pedal, it sends a signal to the brake valve to release the compressed air from the air tanks.
Brake Valve:
The brake valve controls the release of compressed air from the air tanks to the brake chambers on the wheels. When the brake valve is activated, it allows air to flow to the brake chambers, applying the brakes.
Brake Chambers:
The brake chambers are located at each wheel and use the compressed air from the air tanks to push against the brake shoes, causing them to press against the brake drums and slow down the tractor trailer.
Sample Data
Here is a sample table showing the pressure levels in the air tanks and brake chambers during braking:
| Air Tank Pressure (psi) | Brake Chamber Pressure (psi) |
|————————–|——————————-|
| 120 | 90 |
| 100 | 80 |
| 80 | 70 |
Conclusion
In conclusion, air brakes play a vital role in the safe operation of tractor trailers.
