The cage, also known as the universal joint, is a mechanism that can turn direction and can transmit power. Pentium also separates the outer cage and the inner cage. The outer cage is on the front wheel and can be changed horizontally when turning; the inner cage is The center is near the gear box and can be changed up or down when jolting. There is a transmission rod connection between the cage, the cage system transmits power from the gear box to the front wheel, and there are two flexible angle transformations between them, so it is called universal joint.
The cage is actually a complex ball bearing that drives a huge amount of torque and requires good lubrication. It is stuffed with grease. In order to prevent the loss of butter, it is generally necessary to put a dust jacket on the jacket of the ball cage, which is shaped like a rubber sleeve of a “pago pagodaâ€. The function of this boot is very important. If it is broken or not tight, dust will run into the cage. The ball will wear out and the ball cage will be scrapped.
After the cage is damaged, it will generally “click†when turning or jolting, and lose power when it is serious. If you make a "squeaky" sound when you turn, it is usually that the outer cage is broken. In a few cases, the inner cage is broken; if it is a bump, it is a broken inner cage. It should be noted that in most cases of damage, the cage is only "squeaked" when the car refuels "strength" and seldom rings when taxiing.
After the ball cage is broken, long-term wear will cause damage to the ball cage. It should be checked frequently during oil change or other time. If any problem is found, replace the dust boot in time.
Therefore, it is absolutely good to encourage everyone to lift the car up or crawl under the car to check the ball cage. When the dust cover is inspected, it only looks at the appearance of the dust cover. If there is any damage, it will throw off many lubricants inside the cover. It is not difficult to judge.
Under normal conditions of use, the cage is less damaged because it is surrounded by a special high-temperature resistant lubricant, and more damage is caused by dust entering the damaged dust cover. Causes of damage to the dust cover are defects in the manufacturing process itself, and there are also long-term aging branches that have been drilled into the car, and iron and other valuables are punctured.
