How to maintain semi-trailer axle?

The maintenance of semi-trailer axle is the key to ensure its normal operation and prolong its service life. The following is a detailed maintenance guide:

1. Regular inspection

Bolts and nuts:

Check regularly whether the bolts and nuts 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.

Bearings and gears:

Check the wear of bearings and gears, and replace badly worn parts in time.

Ensure that bearings and gears are well lubricated to avoid wear due to insufficient lubrication.

Tires:

Check the tire wear regularly to ensure that the tire pressure is normal.

Timely replacement of severely worn tires to avoid tire problems affecting the normal work of the axle.

2.lubrication maintenance

Bearing lubrication:

Lubricate bearings regularly and use appropriate grease to ensure smooth running of bearings.

According to the frequency of use and working environment, establish a reasonable lubrication cycle.

Gear lubrication:

Check the lubricant level in the gear box regularly to ensure that the lubricant is sufficient.

According to the manufacturer's recommendation, change the gearbox oil regularly to avoid the lubricating effect due to the aging of the oil.

3.cleaning and maintenance

Clean the axle:

Clean the axle regularly to prevent dust, dirt and other impurities from entering the bearings and gears.

Use a high pressure water gun or detergent to clean the axle surface and ensure thorough cleaning.

Anti-rust treatment:

Anti-rust treatment of the axle surface, especially in wet or corrosive environments.

Use anti-rust agent or anti-rust paint to extend the service life of the axle.

4.brake system maintenance

Brake disc and drum:

Check the wear of brake pads and brake drums regularly, and replace severely worn parts in time.

Ensure that the brake system is working properly to avoid safety accidents caused by brake failure.

Brake fluid:

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

According to the manufacturer's recommendation, replace the brake fluid regularly to avoid the braking effect due to aging of the brake fluid.

5.suspension system maintenance

Springs and shock absorbers:

Check suspension springs and shock absorbers regularly to ensure they are working properly.

Timely replacement of damaged or aging springs and shock absorbers to avoid suspension problems affecting the normal operation of the axle.

Air suspension system:

For the air suspension system, check the integrity of the air bag and air pipe regularly to ensure that there is no air leakage.

Regularly check the working status of the air compressor and control system to ensure the normal operation of the air suspension system.

6. Other maintenance items

Electrical system:

Check the electrical wiring and sensors on the axle regularly to ensure that they are working properly.

Replace the damaged electrical parts in time to avoid affecting the normal operation of the axle due to electrical failure.

Records and reports:

Establish axle maintenance records, and record the time, content and results of each maintenance in detail.

Regularly report the use and maintenance of the axle to the manufacturer or professional maintenance organization for professional advice and support.

The maintenance of semi-trailer axle is the key to ensure its normal operation and prolong its service life. DARO trailer axle reminds you that regular inspection, lubrication maintenance, cleaning maintenance, brake system maintenance, suspension system maintenance and other measures can effectively improve the reliability and safety of the axle.
