The symptoms of broken car cages are: abnormal noise or jamming will occur during use. There are two kinds of ball cages on the car: inner ball cage and outer ball cage. To judge the quality of the ball cage, it is recommended to shake the ball cage by hand to feel the gap between the ball cages. Generally, the interior of the ball cage is closely matched, and there is almost no gap. If you feel that the gap is relatively large, it means that the ball cage is seriously worn, that is, it needs to be replaced. The inner ball cage of the car is connected to the differential of the gearbox, and the outer ball cage is connected to the wheel. Whether it is the power take-off or when the car turns, the outer ball cage plays a role. Automobile ball cage is generally composed of bell shell, Trident bearing steel ball, dust cover, harness ring and lubricating grease.

If there is no professional inspection equipment, it is necessary to check the car ball cage mainly:

1. The size of internal and external splines and threads affects the loading size of the cage,

2. Check the size of the oil seal of the outer ball cage. Generally, the oil seal of different models is different,

3. Check whether the groove of internal spline circlip is correct. The width of the groove affects the movement of the cage on the axle shaft after loading;

4. Insert a shaft into the internal spline and swing the cage to see if it can rotate flexibly;

5. Materials, heat treatment performance, etc. need special equipment to check

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!
