Ball cage: selects the import high strength wear resistant steel, after the rough machining of precision forging, cold extrusion, in order to ensure the stability of the internal steel structure of blank, coupled with the appearance of anti-corrosion treatment makes our products more wear-resisting, durable. Greatly prolong the service life of the product.

Shrouds: adopt high quality chloroprene rubber, acid and alkali resistance, abrasion resistance, tensile and tearing resistance, can withstand 38 degrees below zero Celsius to 90 degrees centigrade temperature change and not within the scope of crack; And special formula materials can withstand erosion caused from butter.

Butter: complex lithium grease add 5% molybdenum disulfide, where provide protection for abnormal wear and tear. In the face of the friction of metal and metal and high load condition is the best choice.

Ball cage (C.V.J oint) is short for "ball cage patterned constant speed universal joint". Is an important part in auto transmission system, its role is to transfer power from the transmission of the engine to the wheels, drive the car speeding more for cars. Patterned constant speed universal joint type many, of which the application is one of the most ball cage patterned constant speed universal joint and the triangle frame patterned constant speed universal joint, it has a sliding sleeve, three main shaft, drive shaft, star, cage, bell-shaped shell main parts. Patterned constant speed universal joint transmission heavy driving moment, owing to heavy load, high driving accuracy and high demand, and security, so its main parts are made from fine forging processing.

Outside of the ball cage: the ball cage of steel ball is fixed star set in place and clock form shell of a cage between six window, steel ball in star and clock shape shell is just the half of the position, in order to determine and the role of universal joint Angle, smooth surface treatment that the movement of the universal joint is like a helical gear, six star ball, respectively, to promote their respective sets and clock shell in the fairway, is just a through ball instead of the gear tooth to transmit torque.

Ball cage (fork type) : three goals without steel ball inside the pin type constant velocity universal joint, but instead USES three with needle roller bearings, can be in three bell housing orbital glide. Mainly used in four drove the ball inside the cage, is suitable for the torsion Angle is not in the position of the ball cage, inward and outward slip, in order to adapt to the drive shaft length changes produced during vehicle movement.

Ball cage (six steel-ball) : within such slippage patterned constant speed universal joint products have a different design idea, by the steel ball within the inclined orbit transfer torque and performance of the product excellence, beyond the inside the ball cage of TJ type, but the sliding distance is shorter, can solve the problem of noise, widely used in four-wheel drive vehicle.

Half shaft: half shaft is made up of half shaft rod connects ball cage outside and inside the ball cage, and make the inside and outside the ball cage in the same angular velocity transmission power of the mechanism.

Q: how bad the ball cage?

Answer: because of the great ball cage pass driving moment, the heavy load, under normal wear and tear can make smooth surface becomes rough, to a certain life, will be damaged.

Q: how to judge the ball cage is broken?

Answer: be in commonly steering or turbulence will regularly "kaka" sound, serious when run out of steam. If the steering, "kaka" sound is generally outside the ball cage is broken, a small amount is within the ball cage is broken; If it is bumpy "kaka" sound it is inside the ball cage is broken. Inside the ball cage damaged straight will ring. It is important to note that most of the damage situation, the ball cage is in the "power" gas "kaka" sound, and glide with little noise.

Q: whether must change the entire root half shaft is? Can only change the ball cage?

A: you can only change the ball cage. Usually in the ball cage is ok.

Q: can only change dustproof set?

Answer: after half shaft to be removed, check whether there is ball cage kuang, have into the dust, as the case decided to replace the ball cage dustproof set or change of inside and outside the ball cage.

Q: how to maintenance and inspection at ordinary times?

A: don't use high gear start at ordinary times, or lift the clutch pedal. Overloading, speeding will lead to the damage of the ball cage. Should always check the half shaft connection parts loose kuang, deformation. Have aging dustproof set of ball cage, have crack? Dustproof cover was broken after to change as soon as possible, because the dustproof cover protect the ball cage, inside with grease, dustproof set is broken, if you don't change, time grew fat, dust into the ball cage will cause the ball cage accelerated wear and tear, it is fatal for ball cage. Dustproof set can not be ignored, be safe is the most cost-effective.

Dust cover is one of the key components of the ball cage products, main effect is to prevent dust from entering the ball cage and prevent butter out of the cage. Damage to the ball cage with dustproof set of good or bad has a direct relationship. Special high temperature resistant grease must be used in the ball cage, cannot be replaced with other grease.
