Our truck and semi-trailer slack adjuster is a crucial braking component that ensures driving safety. It is meticulously crafted in strict accordance with industry standards, boasting exceptional quality and stable performance, providing protection for your transportation operations.
| I. Core Functions: Precise Adjustment | 1. Automatic Clearance Adjustment: It can accurately identify and compensate for the excessive braking clearance caused by the wear of the brake friction linings. It ensures that there is always a stable and reasonable theoretical braking clearance (usually around 1.00mm) and an elastic working clearance between the brake drum and the brake shoe. This effectively avoids problems such as weak braking and an extended braking distance due to an overly large braking clearance, or issues like the friction linings dragging, jamming, and locking up caused by an overly small braking clearance, ensuring the stable and reliable operation of the braking system. |
| 2. Stable Braking Torque: During the braking process, it precisely records the changes in the braking clearance. Through its internal precision structure, it enables the smooth output of the braking torque, ensuring consistent and stable braking performance. Whether the vehicle is fully loaded or empty, it can achieve safe and smooth braking. | |
| II. Outstanding Features: Safety Upgrade | 1. Efficient Braking: The push rod stroke of the brake cylinder is short, and the response is rapid. The braking action is agile, which can significantly shorten the braking distance. In emergency situations, it can brake in a timely manner, effectively preventing accidents and providing a strong guarantee for driving safety. |
| 2. Extended Component Lifespan: It reduces the consumption of compressed air and the working load of components such as the air compressor, brake cylinder, and other parts in the compressed air system. This, in turn, extends the service life of these components, reduces maintenance costs and downtime, and improves operational efficiency. At the same time, the stable braking clearance reduces the wear of the braking components, extending the replacement cycle of the braking components. | |
| 3. Protective Design: The adjustment mechanism is tightly enclosed in a sturdy housing, effectively preventing moisture, dirt intrusion, and damage from collisions. It ensures that it can still function properly in harsh working environments, maintaining stable performance and adapting to various complex road conditions and climatic conditions. | |
| 4. Convenient Installation: With a reasonable structural design, the installation process is simple and straightforward. It does not require complex tools or professional skills, reducing the number of manual repairs, lowering maintenance costs, and improving economic benefits. | |
| III. Precise Structure: The Source of Quality | It is mainly composed of parts such as the rack and tooth groove (control arm), clutch, thrust spring, worm and worm gear, housing, and auxiliary components. The rack and tooth groove (control arm) precisely control the theoretical braking clearance value; the combination of the thrust spring and the clutch can keenly identify the elastic clearance and excessive clearance value during the braking process and achieve the rapid connection, disconnection, start, and stop of the force transmission system; the worm and worm gear structure efficiently transmits the braking torque on the one hand and skillfully adjusts the braking clearance when the brake returns on the other hand; the housing and auxiliary components play a key role in transmitting the torque and maintaining the stability of the system. All components work in harmony to ensure the excellent performance of the slack adjuster. |
| Installation Precautions | 1. Model Matching: Before installation, carefully check the compatibility between the model of the slack adjuster and the braking system of the truck and semi-trailer. Different vehicle models and braking specifications require different models of slack adjusters. Incorrect installation will lead to abnormal braking performance. |
| 2. Cleaning Work: Thoroughly clean the installation position to remove oil stains, rust, and impurities. Avoid these foreign matters from entering the braking system, which may affect the normal operation of the slack adjuster and the braking effect. | |
| 3. Correct Installation Position: Install the slack adjuster accurately at the designated position in strict accordance with the design requirements of the vehicle's braking system. The installation angle and direction need to be precise to ensure that its connection and coordination with components such as the brake drum and brake shoes are in the best state. | |
| 4. Tightening of Connecting Components: Use tools with the specified torque to evenly and firmly tighten the bolts, nuts, and other components connecting the slack adjuster. If it is too loose, the components are likely to loosen, affecting braking safety; if it is too tight, it may damage the threads or cause component deformation. | |
| 5. Clearance Inspection: After installation, initially check the braking clearance to ensure that it is within a reasonable range. Generally, the clearance between the brake drum and the brake shoe should meet the standard value specified by the vehicle manufacturer, usually between 0.5 - 1.5 millimeters. | |
| Maintenance Precautions | 1. Regular Inspection: Develop a regular inspection plan. Generally, inspect the slack adjuster at least once every 10,000 - 20,000 kilometers of driving or once a month. Check whether there is any damage or deformation on the appearance, and whether the connection parts are loose. |
| 2. Lubrication Treatment: According to the requirements of the product instruction manual, regularly lubricate the moving parts of the truck and semi-trailer slack adjuster. Use suitable lubricants, such as special high-temperature and wear-resistant greases, to ensure that the internal components such as the worm gear, worm, and push rod move smoothly and reduce wear. | |
| 3. Braking Clearance Adjustment: Regularly check the braking clearance and adjust it in a timely manner. As the vehicle runs and the brake pads wear, the braking clearance will change. When the clearance is too large and the braking effect deteriorates, precise adjustment should be carried out through the slack adjuster to restore it to the normal range. | |
| 4. Dust and Water Protection: Keep the slack adjuster clean to prevent dust, sand, and other substances from entering the interior. At the same time, pay attention to water prevention to avoid rust and corrosion of internal parts due to water ingress, which may affect the performance and service life of the slack adjuster. | |
| 5. Replacement Cycle: Although there is no fixed mandatory replacement cycle for the slack adjuster, when there is irreparable wear, deformation, or damage, or the braking clearance still cannot be maintained within the normal range after multiple adjustments, the slack adjuster should be replaced with a new one in a timely manner to ensure the reliability of the braking system. |
