Difference: the inner ball cage is connected to the differential part of the gearbox, and the outer ball cage is connected to the wheel part. The function of the outer ball cage is the function of the outer ball cage whether it is the power output or the vehicle turning.

The ball cage, also known as "constant velocity universal joint", is an important part of the car transmission system. Its function is to transfer the power of the engine from the transmission to the two front wheels to drive the car at high speed.

Cage, also known as "constant velocity universal joint", is an important part of the car transmission system. Its function is to transfer the power of the engine from the transmission to the driving wheel and drive the car at high speed.

There are many types of constant velocity joints used in cars, among which ball cage type constant velocity joint and tripod type constant velocity joint are the most widely used. They are mainly composed of sliding sleeve, three-way shaft, transmission shaft, star sleeve, cage and bell shell. Because constant velocity universal joint transmits heavy driving torque, with heavy load, high transmission accuracy, large demand and safety parts, its main parts are processed by precision forging.

Outer ball cage: the steel ball of this kind of ball cage is fixed in six windows of a cage between the star sleeve and the bell shell. The steel ball just has half of the position in the star sleeve and the bell shell, once to determine the angle of action with the universal joint. The smooth surface treatment makes the movement of the universal joint like a helical gear, and six steel balls push the star sleeve where they are respectively And the fairway in the trumpet is just to transmit torque through the steel ball rather than the teeth of the gear.

Inner ball cage (Trident type): there is no steel ball in the three ball pin type constant velocity universal joint, but three bearings with needle roller are used, which can slide in three tracks in the bell housing. It is mainly used for the inner ball cage of the four-wheel drive vehicle. It is suitable for the position of the inner ball cage with small torsion angle. It can slide inward and outward to adapt to the length change of the driving shaft when the vehicle moves.

Inner ball cage (six ball type): this kind of sliding constant velocity universal joint product has a different design concept. The torque is transmitted by the steel ball in the inclined track. The performance of the product is excellent, which is beyond the TJ type inner ball cage. However, the sliding distance is short, which can solve the problem of noise. It is widely used in four-wheel drive vehicles.

Electrical equipment e68a84e8a2ade799bee5baa631333365666264 is composed of power supply and electrical equipment. Power supply includes battery and generator; electrical equipment includes engine starting system, ignition system of gasoline engine and other electrical devices.

1. Battery: the function of the battery is to supply power to the starter, and supply power to the engine ignition system and other electrical equipment when the engine starts or runs at a low speed. When the engine is running at a high speed, the generator generates enough power and the battery can store the extra power. Each single battery on the battery has positive and negative poles.

2. Starter: its function is to convert electrical energy into mechanical energy, drive the crankshaft to rotate and start the engine. When the starter is used, it shall be noted that the starting time shall not exceed 5 seconds, the interval of each use shall not be less than 10-15 seconds, and the continuous use shall not exceed 3 times. If the continuous starting time is too long, it will cause a lot of discharge of battery and overheating and smoke of starter coil, which will easily damage the parts.

Tire is one of the important parts of the automobile, which directly contacts with the road surface, and together with the automobile suspension to mitigate the impact of the automobile driving, to ensure that the automobile has good ride comfort and ride comfort; to ensure that the wheels and the road surface have good adhesion, improve the traction, braking and trafficability of the automobile; to bear the weight of the automobile, the tire plays an important role in the automobile People pay more and more attention to its function.

For car owners, nothing is more important than the health of the car, so what waxing, glaze sealing are all expensive, but often neglect the basic maintenance of the car. Many car owners like to repair the car in repair places such as auto parts city, but do not know that if they carelessly use counterfeit parts, they will cause serious damage to the car, the following Taizhou Delivery Machinery is limited. The company will introduce to you some common differences in quality and performance between genuine and fake parts.

Air filter

There is little difference between real and fake parts in appearance, but there is great difference in performance.

(1) From the point of view of filtering performance, the filtering performance of pure brand parts is about 10 times higher than that of counterfeit parts.

(2) From the dimension point of view, pure brand parts are more in line with the specifications required by vehicles than counterfeit parts.

(3) In terms of service life, the service life of pure brand parts is 2 times longer than that of counterfeit parts.

Harm: Long-term use of counterfeit air filters will cause a large amount of dust into the engine, causing serious damage to the engine.

Brake pads

(1) Performance comparison: After the experiment, the brake distance of the car with fake brake pads is 30% longer than that with pure brake pads.

(2) Comparison of heat resistance: The fake brake pads have bad heat resistance, which results in the friction pads falling off from the metal plate at high temperature for a long time, which affects the braking effect.

Harm: Brake pads are the most important parts to ensure human safety. If using counterfeit brake pads, it is likely to cause braking failure in driving, unable to control the speed and bring serious consequences.

Spark plug

(1) Thermal conductivity: From the point of view of the central electrode of spark plug, the central electrode of pure brand spark plug is made of copper material, which can achieve the best thermal conductivity. The thermal conductivity of counterfeit spark plug is much worse than that of pure brand parts.

(2) Heat resistance: The heat resistance of pure spark plug is 2 times higher than that of counterfeit spark plug through heat resistance test.

Harm: Long-term use of counterfeit low-quality spark plugs is likely to lead to electrode melting and engine damage.

As consumers can not recognize the obvious difference between counterfeit parts and pure brand parts from the appearance, so when choosing parts, you must go to the designated distributor to buy pure brand parts, so that you can use them safely and drive safely!

The functional fittings of the outer ball cage include dust-proof cover, clamp, grease and nut.

Dust shield is a protective cover made of rubber (synthetic or natural) or hard plastic (usually the same material). The function of dust cover is to protect oil from dust and water pollution. The dust shield broken, cracked or otherwise damaged should be replaced in time.

Dust-proof covers have been tested by professional machines to ensure that their low temperature resistance must be up to minus 40 degrees, and according to the requirements of the experiment, a number of tensile tests are carried out to ensure that no cracking occurs.

Good repair kit accessories can play an auxiliary role in prolonging the service life of the constant velocity universal joint ball cage.

Traffic safety has always been the most concerned topic of owners, especially now more and more cars, if you drive a little carelessly at ordinary times, it is likely to lead to a major accident. Especially when running at high speed, the speed of getting on the car at high speed is very fast. When driving, the car owners must concentrate on driving, and must not be careless. Therefore, many car owners say that running high speed is really a very tiring thing.

For the car, the performance of the good or bad effect is not too big, may not be accelerated when the blood spray back feeling, even in full load state climbing will feel a little laborious. But the importance of some parts on the car can not be neglected, such as the brake pads which play a very important role in the brake system, time will definitely involve replacement. So, how to judge whether the brake pads should be replaced? Old Driver: There are three ways to do it easily!

First, listen to the sound of the brake. If you can hear the scream of the friction between iron and iron when you brake lightly, it means that the brake pads have to be replaced. In fact, from the principle of the brake pad, we can also know that at this time the brake pad has actually rubbed directly with the brake pad, exceeding the limit of use, if not replaced in time, it is likely that the brake failure will occur. In addition, while replacing the brake pads, the owners should also check the brake disc to see if the brake disc is also worn. If the brake disc is also worn seriously, in case the brake disc should be replaced together.

Secondly, you can check the thickness of the brake pads. The brake pad is made of a certain thickness, and with constant use of friction, the thickness will continue to decrease. Owners can check the thickness of the brake pads. Generally speaking, the thickness of the new brake pads is about 15 mm, and the maximum wear limit is about one third. That is to say, if the brake pads wear down to only 5 mm, it must be replaced at this time. In addition, due to the relative friction between the brake pads and the brake discs, the wear of the brake pads is serious. At the same time, the owners should also check that the brake discs are beyond the wear limit.

The last point is relatively difficult, requiring the owner to feel, that is, to see the brake travel and foot feel at the same time, many old drivers do the same. When the brake pad is used for a long time, the response of the brake system after stepping on the brake will be slow, and the force required for the brake will become smaller, giving the impression that the brake can not be braked. In addition, in addition to brake pads need to be replaced, car owners also need to check the brake oil regularly, so as to ensure that the normal driving time is safe!

The replacement cycle of brake oil is usually determined according to the time. Most automobiles require replacement once every two years, but there is no special requirement for mileage. If we want to know more accurately whether the brake oil needs to be replaced, the best way is to test the moisture content of the brake oil. If this value exceeds 3%, we suggest replacing it; if the moisture content exceeds 5%, it must be replaced.

Normally, the moisture content of brake oil is less than 1%. If it is too high, the boiling point of brake oil will be lowered, which will lead to boiling vaporization of brake oil and brake failure in high-strength braking of automobiles. Experiments show that when the water content of brake oil reaches 3%, the boiling point of brake oil will be reduced by 25%. If the water content of brake oil reaches 7-8%, the boiling point of brake oil will be reduced by more than 50%. For example, the dry boiling point of some brake oil is 210 C. When the water content exceeds 3%, the boiling point has been reduced to 152 C. If the water content of the brake oil reaches 7-8%, the boiling point may have been reduced to about 100 C.

How long will the water content of brake oil exceed the standard? Experiments show that when a new car runs for 12 months, its brake oil may inhale about 2% of the water; when it runs for 18 months, the water content can reach 3%; when it runs for more than five years, the water content of the brake oil will reach 7-8%. If the water content is more than 3%, we suggest replacing it. This is also the reason why many automobile manufacturers stipulate that brake oil should be replaced once every two years.

Of course, you can also appropriately extend or shorten the replacement cycle according to the local environment and personal use conditions. If the local climate is dry and personal driving is not intense, it is no problem to replace the brake oil for three or four years; if the local climate is very humid or often wading, it is recommended to shorten the replacement cycle properly, preferably once a year.
