Sinotruk az2203210317 Pneumatic amplifier assembly

Product representation

1. The main stages of work

1.1. Entering air

Air compression ： Pneumatic storage is connected to the compressor of the air compression system. The compressor accumulates air in the tank under pressure (usually 8-10 bar).

The preliminary pressure valve ： When you press the brake pedal, the valve opens, passing the compressed air into the amplifier working chamber.

1.2. Transformation of force

The arc membrane ： compressed air acts on a bilateral membrane with an area of ​​320 cm². This is a creative pressure that multiplies the force attached to the pedal by 4-6 times.

The mechanical transmission of the ： membrane is connected by the catfish, which directs the effort to the main cylinder of the brake system, increasing the pressure in the brake highways.

1.3. Pressure control

The regulation system ： amplifier is equipped with a pressure sensor that signals the controller about the current value. The controller automatically adjusts the air supply to maintain stable pressure (for example, 12 bar for Sinotruk Howo).

Operating modes ：

Rapid pressure growth (up to 12 bar in 0.3 seconds) for emergency braking.

Sustainable pressure on the steepness mode.

2. Technical design features

2.1. Materials and tightness

A stainless steel body with an anti -corrosion coating, protected from exposure to salt solutions and acids.

A sealed membrane of silicone rubber from -40 ° C to +120 ° C, preventing air leaks.

2.2. Safe systems

Emergency shutdown ： If the pressure in the system falls below 5, the valve automatically blocks the air supply, preventing complete brakes.

The anti -blocking system ： integrated with ABS, prevents wheels lock during sharp braking.

2.3. Energy saving

A pneumatic pump with an inverter system ： reduces energy consumption by 25% due to automatic speed control depending on the load.

3. Compatibility and maintenance

Installation on Sinotruk Howo and Steyr ： Standard mounts and the diameter of intake pipes (1/2 ") provide compatibility without modifications.

Diagnosis ： Built -in error sensor signals the malfunctions through the on -board computer.

Replacing parts ： membrane and valves can be replaced for 30 minutes using a standard tool.

4. Efficiency in numbers

Reaction time ： 0.3 ​​seconds (standard - 0.5 seconds).

Acceleration of pressure drops ： decreases by 40% compared to previous models.

Trinous operating time ： 500,000 cycles (24 months warranty).

Submissive air: the system begins to work when the compressor accumulates compressed air in the battery. When the driver presses the brake pedal, the preliminary pressure valve opens, allowing the compressed air to get into the air -stitching.

The effort from the membrane: in the pneumopoliter, compressed air acts on the membrane. The pressure difference on both sides of the membrane creates the force that is transmitted to. Due to the large size of the membrane of and the pressure, the force attached to KU, is much more than the force attached to the pedal of the brake by the driver. Thus, an increase in braking force is achieved.

The transfer of force to the brake system: ， Having received strength from the membrane, moves and presses on the main cylinder of the brake system. This leads to an increase in the pressure in the brake highways, and then the brake pads are pressed against the brake discs or drums, creating the inhibitory force that stops the machine.

Control and security systems

Pressure regulation system: A pressure sensor is installed in the pneumatic altel, which constantly monitors the pressure in the system. The controller, having received a signal from the sensor, can automatically adjust the supply of compressed air to maintain optimal pressure in the brake system. For example, if the pressure becomes too high, the controller reduces the air supply; If too low, increases.

The emergency braking system: in the case of a breakdown of the main brake equipment or a drop in pressure in the system below the critical level, the air -cane can activate the emergency system of braking. For example, reserve valves are provided, which can automatically block the air supply in certain situations in order to ensure a certain degree of inhibition and safety.

Integration with the ABS system: AZ2203210317 pneumatic power system is integrated with the brake anti -lock system (ABS). When the ABS system determines that the wheels begin to be blocked, it interacts with the pneumatic submarine in order to adjust the pressure in the brake system and prevent complete locking of the wheels, while ensuring the maximum brake efficiency and stability of the car during braking.

Design features affecting work

Building materials: the case of the pneumatic power of the capacity is made of high-strength and corrosion-revistant materials, such as special alloys or stainless steel. This allows the device to work in various environmental conditions, including humidity, high and low temperatures, and be resistant to various chemicals.

System tightness: to ensure the proper operation of the pneumatic capacity, it is important to have good tightness. The membranes, seals and connections in the system should be sealed to avoid compressed air leaks. If there is a leak, the pressure in the system may decrease, which will negatively affect the efficiency of braking.
