Structural plan of the Wheel Hub Assembly

The structure plan of the Wheel Hub Assembly, which is the key component that connects the suspension, braking and car wheels to keep the wheels rotating freely and safely.

Here is a detailed description of each component in assembly order:

1.Core Group and Bearings (Core & Bearings)

This part serves to load the car and reduce friction to keep the rotating wheels fluid:

• Dust Cap (Dust Cap): Closed over the outermost core to prevent dust, soil and moisture into damaging the ball bearing.

• Hub Flange (Hub Flange): A circular plaque with Wheel Studs (Male Knots) embedded. It is a point used to hold wheels and brake plates.

• Bearing (Inner & Outer Race): Wheel bearings. Divided into inner rails and outer rails. Inside, bearing pellets assist in rotation.

• Seal (Oil Resistant Seal): Prevent Lubricant Grease Flow Out, and Prevent Exterior Dirt Into Bearings

• Circlip (Lock Ring): Use to lock the bearing in place inside the hub top, not to move out.

2. Main Structure

• Hub Carrier (Hub / Horse Neck Top): The strongest piece of metal, serving as a housing for the bearings, and as a connection point to the suspension system (e.g., pinion props, and shocks)

• ABS Sensor Ring (ABS Sensor Ring): A ring with teeth, serving to send speed signals around the wheel to the ABS sensor for use in controlling the anti-lock system.

3.Braking & Wheel System

• Brake Disc (Brake Plate): It is worn on the wheel knots on the hub. When we step on the brakes, the brake pads clip on this plate to stop the car.

• Wheels (wheels and tires): The last part assembled into the wheel knots (Bolts) to transfer power down to the road floor.

How it works

1.Propulsion: The power from the driveshaft is transmitted to the Wheel Hub, causing the wheel to rotate.

2.Support: The Hub Carrier will load the car through the bearing (Bearing), allowing the hub to rotate while the car body is still on the suspension system.

3. Safety: The ABS Sensor Ring will always check how fast the wheel is rotating. If there is sudden braking, the system will prevent the wheel from dying. Note: If you hear a whining or a "blurry" noise when running, or feel that the steering wheel is often caused by Bearing, starting to deteriorate or dry grease. Manual inspection and repair of the car. In addition to saving costs, it will help you understand the operation of the car and increase the safety of driving. The main steps should be given as follows:

1.Fluid system Czech examination (Fluids)

Fluid is the centrepiece that helps lubricate and cool the engine.

• Engine Oil: Pull out the motor oil measuring rod, wipe it, and plug it back in to see the oil level (should be between the Min and Max dashes) and observe the color. If it is pitch black or thick sticky, it should be replaced.

• Coolant: Check if it is at the specified level (Do not open the radiator lid while hot)

• Brake Oil and Power Oil: Check the level at the engine room oil jar. If abnormally reduced, there may be a leak point.

2.Rubber and Suspension System Inspection (Tires & Suspensions)

• Tire Pressure: Check uniformly according to the standard value attached next to the driver's side door.

• Tread: Use the baht coin to plug into the groove to check the depth. If the tread is felt until the rubber bridge strip, it should be replaced immediately.

• Tear or swelling: Note whether the tire cheeks are convex or torn because it can cause the tire to explode while driving. 3. Lighting and Signal System (Lights & Signals)

Every Czech should be checked to make sure the companion sees signs from you:

• Headlights (high-low)

• Left-right turn signal and emergency light

• Brake light (can be checked by retreating the car near the wall and stepping on the brakes to see the glare)

4. Battery Care (Battery)

• Salt wax: If there is a green and white stain on the battery terminal, use the hot water to wash it off and dry it.

• Terminals tightness: Try to gently move the battery terminals if they are still tight.

• Refined water level: If it is a refined water-filled battery, it must always be checked to the right level.

5. Replacement of basic consumable equipment

If a small problem is encountered, you can fix it yourself as follows:

• Wiper Blade: If swiped and stained or noisy, it can be easily purchased to replace by unlocking the original latch.

• Fuse: If some electrical equipment is extinguished (such as a cigarette lighter or car light), check the fuse box and replace the original Ampere size. Caution: If you find complex abnormalities such as strange noises from the engine room, shaking steering wheel, or engine warning lights on the dial, you are advised to bring the car to the expert for safety.
