The quality of brake system has a significant influence on the safety and reliability of agricultural vehicles, but the quality problems of brake system can easily cause accidents and increased maintenance costs, so the improvement of brake system quality is extremely important .
1. The source of quality defects
The braking system is a complex combination of mechanical, hydraulic, and electrical systems. Defects may occur due to various factors such as errors in design, manufacturing errors, wear and aging of parts, lack of maintenance, etc. Design errors include miscalculation of braking force, incorrect use of materials, etc. Manufacturing errors are caused by incorrect assembly or incorrect raw materials, etc. Wear and aging of parts result in reduced braking effect, increased noise, and uneven sensitivity. Maintenance faults can easily cause a decrease in braking force and an increase in noise.
2. Quality defects and their solutions
(1) Reduced braking force. This problem can be solved by checking and replacing the brake pads, brake lines, brake discs, and wheel cylinders; checking the state of the master cylinder; adjusting the brake balance; replacing the brake fluid; and checking the braking system for air leakage.
(2) Uneven sensitivity. This issue can be solved by check the brake system for air leakage. Additionally, the brake master cylinder and the brake proportion valve should be checked and adjusted.
(3) Excessive noise. This can be solved by replacing the brake pads, cleaning the brake disc groove, and replacing worn out parts; checking the brake caliper and disc for any damage.
(4) Rapid wear and tear. This can be solved by using high quality raw materials and parts, making sure the brake system is regularly maintained and inspected, and avoiding overuse of the brake system.
3. Improvements in quality
(1) Imporve the design. The performance of the brake system can be improved by optimizing design parameters such as correct brake cylinder bore, valve tuning, and proper valve displacement.
(2) Use higher quality components. Higher quality components should be used, such as high-grade brake discs and pads, improved quality diaphragms, wear-resistant rubber components, and corrosion-resistant steel components, to reduce wear and tear.
(3) Improve process quality. To reduce defects in manufacture, production processes such as stamping, forging, casting, welding, and machining should be strictly controlled.
(4) Improve assembly quality. Proper assembly techniques should be used and a team of highly trained technicians should be employed to make sure all components are correctly and safely installed.
(5) Improve maintenance. Regular maintenance, such as brake fluid replacement, brake disc cleaning, and inspection of the brake system for air leakage, should be carried out periodically or after a specified amount of operation time.
In conclusion, improving the design, quality, and maintenance of agricultural vehicle braking systems is essential to ensure their reliability and safety. The proper use of high-quality components, rigorous control of production processes, correct assembly techniques, and regular maintenance will help to reduce defects and improve brake system quality.
