Precautions for the use of semi-trailer disc axle

Because of its excellent braking performance and good heat dissipation effect, the disc axle of semi-trailer has gradually become the first choice in many transportation scenarios. However, in order to ensure its safety and service life, the following matters should be noted when using:

1.Daily use precautions

Avoid overloading:

Although the disc axle has strong carrying capacity, overload will aggravate the wear of the brake system and axle and affect the driving safety.

Strictly in accordance with the rated load of the axle to avoid overload operation.

Smooth driving:

Avoid rapid acceleration, sharp braking and sharp turns to reduce the impact on the brake disc and axle.

In long downhill sections, try to use engine auxiliary braking to reduce the burden of the braking system.

Pay attention to road conditions:

When driving in muddy, sand and other complex road conditions, pay attention to avoid foreign bodies into the brake system, resulting in brake disc wear or stuck.

After passing through the waterlogged section, gently step on the brake to remove the water on the brake disc and restore the braking performance.

2.Brake system maintenance

Check brake discs and pads regularly:

Check the thickness and surface of the brake disc is smooth, if there are cracks, serious wear or deformation, need to be replaced in time.

Check the wear of the brake disc to ensure that its thickness is within the safe range, and replace it in time when the wear is serious.

Keep the brake system clean:

Clean the dust, oil and foreign matter on the brake disc and brake disc regularly to avoid affecting the braking effect.

Check that the brake calipers are flexible and that they are working properly.

Check brake fluid:

Check brake fluid level and quality regularly to ensure that brake fluid is adequate and pollution-free.

Replace brake fluid regularly as recommended by the manufacturer to avoid brake fluid aging affecting brake performance.

3. axle maintenance

Regular lubrication:

The axle bearings, gears and other moving parts are regularly lubricated to ensure smooth operation.

Use high quality grease to avoid wear due to poor lubrication.

Check fasteners:

Regularly check whether bolts, nuts and other fasteners on the axle are loose to ensure that the connection is firm.

Use a torque wrench to tighten according to the manufacturer's specified torque values.

Clean the axle:

Regularly clean the surface of the axle to prevent the accumulation of dust, soil and other impurities, affecting heat dissipation and performance.

When used in corrosive environment, anti-rust treatment is performed on the axle.

4.temperature management

Avoid overheating:

The disc brake will produce high temperature during frequent braking, and attention should be paid to avoid overheating of the brake system.

In long downhill or frequent braking sections, the rational use of auxiliary braking systems (such as retarders) to reduce the load of the brake disc.

Check heat dissipation performance:

Ensure that the heat dissipation channels of the brake disc and brake disc are smooth to avoid performance degradation due to poor heat dissipation.

Check the ventilation design of the brake system regularly and clean or repair it if necessary.

5. Troubleshooting

Abnormal noise:

If there is abnormal noise (such as sharp sound or friction sound) during braking, it may be that the brake disc is worn or foreign matter stuck, which needs to be checked and dealt with in time.

Braking effect decreases:

If the braking distance becomes longer or the braking force is insufficient, it may be insufficient brake fluid, brake disc wear or brake disc deformation, and it needs to be repaired immediately.

Vibration or jitter:

If you feel the steering wheel or body shaking during braking, it may be that the brake disc is deformed or worn unevenly, and it needs to be replaced or repaired in time.

DARO trailer axle reminds you that disc axle has excellent braking performance and heat dissipation effect, but in the process of use, attention should be paid to avoid overload, smooth driving, regular maintenance of the brake system and axle, and attention to temperature management and fault handling. Through scientific use and careful maintenance, the advantages of disc axle can be fully utilized to ensure driving safety and extend its service life.
