Sinotruk WG9000360609 Brake chamber original

Detailed product information

Structural composition: usually consists of an air chamber of the brake, diaphragm, pusher, return spring and other components. The hull of the air chamber of the brake is usually made of high -strength cast iron or aluminum alloy, which has good strength and corrosion resistance. The diaphragm is a key component, mainly made of rubber or composite materials used to convert the compressed air into a pusher's thrust. The pusher rod is usually made of steel, and its surface is chrome or subjected to other anti -corrosion treatment to guarantee that it will not rust or get stuck with frequent extensions and retraction. The return spring provides the force required to return the pusher to the starting position after braking.

The principle of operation: when the compressed air of the brake system enters the air brake chamber, the pressure affects the diaphragm, forcing it to deform, thereby pushing the pusher. Then the pusher transfers an effort to components such as a brake block or brake caliper to achieve the braking function. After braking, compressed air is released, and the return spring returns the pusher and the diaphragm to its original position.

Technical characteristics and models: There are various technical characteristics and models in accordance with various models and requirements for the Sinotruk brake system. For example, the diameter can be 245 mm, 305 mm and other different sizes, and the piston course can also be different: 50 mm, 80 mm, 100 mm, etc., to adapt to various requirements for braking and space for installation.

Productivity parameters: working pressure usually is 0.6-0.8 MPa, and maximum working pressure can reach about 1 MPa. The ensured braking force varies depending on specifications. Small brake chambers can provide braking for several thousand Newtonians, while large can reach tens of thousands of Newtonians or even higher.

Installation

Preparation before installation: check if there are damage or deformations of the brake chamber, are there any cracks or signs of aging on the diaphragm, and whether it is possible to flexibly extend or pull the pusher. Prepare the tools necessary for installation, such as wrenches, screwdrivers, calibrations, etc. Clean the installation site, remove oil, dust and rust and make sure that the installation surface is smooth and clean.

The specific stages of the installation: place the brake chamber in a given installation position and fix it on the frame or axis with bolts or clamps to ensure its reliable installation, and the moment of tightening the bolts must meet the specified requirements. Connect the brake highway and correctly connect the aeronage from the brake valve to the air intake of the brake chamber, making sure that the connection of the pipes is airtight and there are no leaks. Install the connecting parts between the pusher and the brake block or the brake caliper and adjust the length and angle of the pusher so that the brake chamber can effectively push the brake block or brake caliper during operation to achieve a good braking effect. After installation, check the reliability of all connections, the lack of twisting and pinching of the tubes, and then repair and pump the brake system.

Common errors

Leakage

Reasons: the diaphragm was old and cracked, which leads to a leakage of compressed air from the diaphragm; The seal of the brake chamber body is damaged, which leads to a leakage of air from the connection of the case; The connection of the brake tube is weakened and poorly sealed, which leads to air leakage.

Influence: insufficient air pressure during braking leads to a decrease in the brake force, an increase in the brake route and affects the safety of driving.

The pusher is stuck or does not return to its original position

Reasons: the surface of the pusher rustled and worn out, which leads to poor fit to the inner opening of the brake chamber body; The return spring is tired and broken and cannot provide a sufficient return force; Narround objects fall into the brake chamber, making the movement of the pusher.

Effect: if the wheels cannot release the brakes after braking in time, this will lead to a slip of the wheels, increase the wear of tires and fuel consumption. In severe cases, this can lead to overheating of the brake drum or brake disc, which will lead to the refusal of the brakes.

Insufficient braking force

Reason: In addition to air leakage causing insufficient brake force, a decrease in the area of ​​the diaphragm (for example, damage to the diaphragm), wear of the piston or pusher inside the brake chamber and low air pressure in the brake system can also lead to insufficient brake force.

Exposure: the braking distance of the car increases significantly, and in an emergency it is impossible to stop the car in time, which can easily lead to traffic accidents.

To Judge the Failure of Sinotruk Air Brake Chamber, We Can Start from the Following Aspects:

Appe their infection

Brake Chamber Housing: Carefully Check Cherke The Brake Chamber Housing Has Cracks, Damage Or Deformation. Cracks May Cause Compressed Air Leakage and Affect the Braking Effect. IFVVIOS CRACKS or DeFORMATION ARA Found on the Surface of the Housing, Especially At the Connection Part or Cures Greater, Further Institution and Treatment Are Required.

Diaphragm: Check Whather the Diaphragm Is Aged, Damaged or DeFORMED. The Diaphragm is a Key Sealing Component of the Air Brake Chamber. If the is a problem with the diaphragm, it Will Directly Lead to Air Leakage. IT Can Be Judged by Observing the Surface Condition of the Diaphragm, Such AS Whather the ARE CRACKS, Wear MARKS Or HARDING and Hardening of the Rubber.

PUSH ROD: OBSERVE HETHER THE PUSH ROD IS Bent, Worn Or Rusted. The Normal Extrance and Contract of the Push Rod Is Crucial to the Realization of Braking. IF the Push Rod Is Bent or Severely Worn, It May Cause Brake Jamming orufficent Bracking Force. Rusty Push Rods May Affect Their Sliding Inside The Brake Chamber and Need to Be Handled in Time.

Connecting Pipeline: Check Whather The Connection Between The Brake Chamber and the Brake Pipeline is Firm, and Whater the Pipeline Has Signs of Damage, Anging Org Leakage. Loose Conneptions or Broken Pipes Cause Compressed Air to Leak, Reducing the Braking Effect. You can Determine there is is a leak by Checking Whather there Bubbles Coming Out of the Connection Parts.

Air Pressure Detection

Static Air Pressure Detection: When The Vehicle Is Stationary, Start the Engine to Make the Air Pressure Reach The Normal Working Range (Generally 0.6-0.8MPA), and the Turn Off the Engine. OBSERVE The Reading of the Barometer. IF the Air Pressure Drops Significantly in a Short Period of Time, It Means that is a leak in the brimate system, Which May Be a Air Brake Chamber Or Related Pipes. At this time, you can check each brake chamber one by one, and Determine the leak point by applying water to each concretion? there are bubbles.

Dynamic Air Pressure Detection: Observe the Changes in the Barometer During Vehicle Driving. If the Air Pressure Drops too Quickly During Bracking, Or the Air Pressure Rates Slowly Inter Releasing the Brake Pedal, It May Indicate IS a Fault in the Air Brake Chamber. In Addition, You Canso Judge by Listening to the Sound During Bracking. Under Normal Circumstances, There Shoup Be Obvious Airflow Sound During Braking. If the Sound is Abnormal, Such as too Lawd or Too Small Airflow Sound, It May Indicate a Prince with The Brake Chamber.

Bracking Performance Test

Bracking Effect Test: Perform a Bracking Test in a Safe Venue to Feel The Braking Performance of the Vehicle. IF the Bracking Distance Is Found to Be Significantly Longer, Or the Vehicle Deviates During Bracking, It May Bet the Air Brake Chamber Is Fauty and the Bracking Force is insuffic or unven. For Example, If the Bracking Force of a Brake Chamber Decresses, The Vehicle Will Deviate to the Side with Normal Bracking Force During Bracking.

Brake Pedal Stroke Test: Check Whather The Brake Pedal Stroke is Normal. IF the Brake Pedal Stroke Is Too Large, It Means that May Be a Problem with the Bracking System, Which May Caused By Insucy Rod Stroke of the Air Brake Chamber or Diaphragm Failure. Under Normal Circumstances, The Brake Pedal SHOULD HAVE A CERTAINSISTANCE AND STROKE RANGE. IF the Pedal Stroke Feels Abnormally Soft or Too Large, The Brake Chamber Needs to Be Further CHECKED.

Abnormal Sound Inspection

During the Driving of the Vehicle, Pay Attend tohes There Is ABNormal Sound Coming from the Brake Chamber. For Example, When The Pushh Rod of the Brake Chamber Rubs or Other Parts, Metal Friction SoundCt Sounds May Be Generated. In Addition, if the Diaphragm is Damage or Return Spring is Broken, Abnormal Sounds May Also BE EMITTED. The Source and Characteristics of the Abnormal Sound Can Be Used to Preliminarly Determine the Fault of the Brake Chamber.

Through The Comprehensive Judgment of the ABOVE METHODS, IS Possible to More Accuramine Heremine is a Fault in the Sinotruk Air Brake Chamber and the SPECIC CAUSE OF THE FULT, SO AS CARRY OUT REPAIRS AND PROCESSING IN TIME to ENSURE THE SAFE and RELIABLE OFERATION OF THE VEHICLE BRAKING SYSTEM.
