Production Description:
Cage (cage) is also called "constant velocity universal joint" is the important parts of the automobile transmission system, its role is to the power of the engine from the transmission is transmitted to the driving wheel, driving the car at high speed. For a lot of car of constant velocity universal joint type, one of the most widely used is of ball cage patterned constant speed universal Festival and tripodal constant velocity section, it is mainly the sliding sleeve, three to shaft, drive shaft, star, keep frame, bell housing the main parts of the composition. Due to the constant speed universal joint transmission of heavy driving torque, with the load weight, high transmission accuracy, high demand, and safety parts, so the main parts are processed by precision forging.Originally our country used for car production and car maintenance of constant velocity universal joint mainly rely on imports, every yearNeed to spend a lot of foreign exchange. For the development of China's automobile industry, after more than ten years of research and development of constant velocity universal joint for automobile mainly blank precision forging technology and production technology. Now with the production technology of the domestic manufacturers, but also a lot of, like Wafangdian Hongda (ZWZ), Shanghai GKN (SDS), Hangzhou Wanxiang, Taizhou Jutai (bik), Taizhou Hongli (Lee), Wenzhou Guansheng (GSP), Ningbo million navigation domestic manufacturers factory production of ball cage has been with the domestic and foreign OEMs to provide supporting! The production line is composed of spherical shell, cylindrical shell, forging line and star set, set three to the axle temperature of closed die forging line.Dust cover for cage products is a key component, the main role is to prevent dust entering the inner ball cage and prevent the outflow of inner ball cage of butter. Must use special high-temperature grease ball, can not be replaced by other grease.An outer ball cage:1 bell type shell2 star3 holder4 ball5 dust cover6 beam ring7 grease (unlike butter, is the main component of molybdenum disulfide).In the service composition:1 bell type shell2 trigeminal or ball bearing. (there are two kinds of respectively in this)3 dust cover4 beam ring5 grease (unlike butter, is the main component of molybdenum disulfide).Ball: the ball of the ball is fixed placed between the star and bell housing a maintained in six window frame, ball in the star shaped sleeve and bell housing just the half of the position, to identify and gimbal angle, smooth surface treatment makes the gimbal motion like a helical gear, six steel balls are respectively to promote their respective of star shaped sets and bell housing in the fairway, but is through the ball and not the gear teeth to transmit torque.Inner ball cage (Trident): three ball pin type constant velocity universal joint which do not have the ball, but the use of three with a needle roller bearing, can in the bell housing three track in slip. Is mainly used for four-wheel drive in ball cage, applicable to reverse the position of the small angle of inner ball cage, can the inward and outward slip, so as to adapt to the drive shaft when the vehicle is moving in length changes.Inner ball cage (six bead type): such slip type constant velocity universal joint with a different design philosophy, which by the steel ball in the oblique orbit transfer torque, excellent product performance, beyond the TJ in the cage, but the slip distance is short can solve the problem of noise. In the Raider Buggies used more widely.Commonly known as the ball CVJ cage and the outer cage, it should. A steel shaft is connected with the middle and ball cage, referred to as the drive shaft, just as its name implies, it is transferring the power of the axis of rotation, and in turn drives can transfer constant, then its fault can be used emergency refueling doors and made a U-turn to the judge. Two simple to check in metal such as a U-turn to hear a "click" sound is generally outside the cage damage, in the general case outside the cage of life is very long, about two hundred thousand kilometers above, and our car maintenance if not attention to the ball and dust cover is damaged, so that a large number of dust in running the incorporation of cage, the life also is a few months, so in this sense speaks regularly often check ball and dust cover is damaged, the basic can guarantee the cage can not be damaged, you only need to look down at close to the front tire inner ball cage dust cover and close to the gearbox of the two ball and dust cover is black grease exudation. When you in the straight line driving, low speed urgent step on the accelerator, at this time such as the inner ball cage damage will send metal "KaKa" sound, because the ball to transfer power, so when the load of ball cage urgent step on the accelerator to the limit because of damaged parts will be issued abnormal sound. The outer cage not only transmit power, and is also responsible for the steering speed transmission, cage damage not only U-turn large angle steering has abnormal noise, serious, in the straight line driving, feel someone in and you grab the steering.
