Air Brake Systems and Caliper Repair Kits in Truck, Trailers and Buses
Modern commercial vehicles are equipped with air brake systems. The principle of operation of air systems is based on the use of compressed air energy. Using air as a working gas is a kind of technical solution. This is the main feature of this type of air brake systems and the main difference from others seen in practice. Air brake systems are equipped with many controls and designs. Air brake systems use a general operating principle
STRUCTURE AND PARTS OF AIR BRAKE SYSTEM
Compressed air in the air braking system is produced by a compressor, driven by the engine. Reciprocating type compressors are generally used in vehicles with air braking system
Compressed air is transmitted to the brakewheel mechanisms by various auxiliary elements. Braking is achieved bytransferring the pressure force to the pads. Air brake system consists of compressor, pressure regulator, brake pedal valve, brake bellows, air relief valves, hand brake valves, water relief valves, air tanks and safety valves
GENERAL PRINCIPLE OF ACTION OF AIR BRAKE AIR SYSTEM
Simplified principle of action can be described as follows: Air pump - a compressor that is driven by an engine pumps air from the atmosphere into the system. Thanks to the pressure regulator, the air pressure provided by the characteristics is created and maintained in the system. The stock of air compressed by the compressor is accumulated in special cylinders - receivers attached to the vehicle frame. When the driver presses the brake pedal, air from the receivers through the tubes and hoses fills the brake chambers. With their rods, the chambers act as brake pad mechanisms. The brake pads transmit compressed air energy to the brake drums (discs) of the wheels. When the driver releases the brake pedal,the air from the brake chambers returns to the atmosphere. The mechanical partsof the system with the help of built-in springs take their initial position.The truck picks up speed again
THE BASIC OPERATING ELEMENTS OF AIR BRAKE SYSTEM
Compressor, air pump, pressure regulator, air dryer, four-circuit safety valve, circuitreceivers, foot brake valve, brake chambers, manual brake valve, poweraccumulators, pressure gauge
OPERATIONOF THE BRAKE AIR SYSTEM
When the engine starts, the compressor is simultaneously turned on. It takes in atmospheric air and feeds it into the system until the operating pressure is reached. The pressure in the system determines and limits the pressure regulator. Excess air is directed through the exhaust valve back into the atmosphere. After the pressure regulator, air is driven through a dehumidifier. This device is necessary for filtering various impurities and retaining atmospheric moisture vapor. Dry air ensurestrouble-free operation of the system, especially in frosty times. In most systems, the pressure regulator and dehumidifier are combined into a singleunit, equipped with a small separate receiver. The receiver helps the dehumidifier to perform a regeneration function. After the dryer, air is distributed by a four-circuit safety valve
In addition to air flow separation, thevalve provides: sequential filling of circuits with compressed air
The driver controls the main brake valve through the brake pedal. Through the cavity of the brake valve, air under pressure is pumped into the brake chambers of the front wheels, and through the control elements, the brake chambers of the rear wheels. Chambersby rods act on the mechanisms of breeding (compression) of brake pads. The truck is braking
In the circuit of the parking and emergency brake systems, air from the receiver is fed to a manual brake valve, which controls the air supply to the energy accumulators, which are usually installed on the rear wheels. A manual brake valve relieves pressure from such an accumulator. As a result, the spring acts on the actuating mechanisms. It forces pressure on the brake chamber rod, ensuring the safe parking of the truck. Power accumulators help to avoid an accident while driving. When the pressure of the system drops below permissible, they brake the machine
From the receiver of the circuit of the parking and emergency brake systems,power is supplied to the trailer brake control valve. The air systems of the vehicle and the trailer are connected by means of supply connectingheads. The control signals to the trailer braking system are simultaneously received from the brake systems ofthe vehicle: working, parking, and emergency
The airbrake system of a truck is a technically complex mechanism. A heavy dimensional machine must behave reliably and predictably on any road. Knowledge of the device, the principle of action of the caliper repair kits of the brake system such as caliper adjusting mechanism set, caliper boot pin repair kits, caliper boot set will help in the proper care of it. In gratitude, the brakes will not fail the driver in an emergency
