The brakes are definitely not to be neglected. I have heard the old driver say, "If you want to learn to drive, you must first learn how to brake." Especially for heavy-duty trailers, the brake system is a very complicated As a whole, problems in any one of these links may pose a threat to traffic safety. The brake cylinder is one of the important components in the whole process. Its performance is directly related to the braking force of the vehicle.
Newly purchased trailers can be equipped with six Ryril branch pumps if they do not use the brake cylinders that are standard in the original car. The most important thing about the truck is the braking system. This is directly related to life safety. No one step can be sloppy. Even a small brake cylinder, we must put an end to the cottage products.
The master of maintenance during assembly said that the brake cylinder is a wearing part and the structural principle is very simple. According to his maintenance experience, the push rods and cups inside the brake cylinders are often easily damaged structures, especially the cottage products. The direct result is that the sub-pump leaks when braking and the brakes are not working.
Poor quality cottage brake cylinders, where the top cover screws are also very easy to damage, the quality is simply not off.
Authentic energy storage spring is obviously much higher than Shanzhai products, do not underestimate this gap, a little difference in elasticity can be far worse. The spring is usually used as the power for the parking brake, but in emergency situations, such as the abrupt loss of air pressure, the role of the spring is to allow the truck to stop in an emergency. If the spring does not have enough spring force, it may cause a very serious accident. This is one of the most important gaps between the sub-cylinder and the genuine sub-pump. This aluminum part is the middle part of the brake cylinder. It is made of cast aluminum and is responsible for dividing the cylinder into two working chambers. From the appearance alone, the authentic products are obviously more delicate than the cottage products, and the return spring in the middle is also stronger than the cottage products. The middle putter part was intended to continue dismantling, but it was found that the authentic product was connected by riveting. Although there is no way to dismantle, it is highly reliable. Shanzhai products use ordinary screw connection. In actual use, this screw is easy to loose. Loose screws often cause the diaphragm to leak and make the pump leak. The push rod is responsible for transferring all the braking force generated by the compressed air to the adjusting arm, and the working intensity is very large, which is one of the most easily damaged parts of the entire internal pump. It is believed that many card members have experienced failures in the subpump leak caused by rupture of the diaphragm at the pusher disc, and the root cause of such failure is insufficient strength at the pusher disc.
Inferior parts look cheap, but the overall cost actually used is not cheap. In the case of a high-strength use environment, a poor quality product has a very short life span, and the failure of the housing to burst or the push rod to damage the air leakage will soon occur. While the famous and high-quality products are slightly higher in price, they are difficult to use for a long time, and the overall accounting is still very suitable, and the safety is also much stronger than inferior products.
At this stage, many trailer manufacturers on the market are not perfect in the brake system. The brake cylinders are also mixed. If there are problems during use, it will cause a heavy burden on the maintenance. Therefore, we must be cautious when choosing the brake air chamber, and try our best to choose famous brand products.
