Outer CV Joint – CVJ-18235

The automobile ball cage is divided into an inner ball cage and an outer ball cage, also called a constant velocity universal joint. It is an important component in the automobile transmission system. Its function is to transmit the engine power from the transmission to the two front wheels, driving the car to travel at high speed. The inner ball cage is connected to the differential part of the gearbox, and the outer ball cage is connected to the wheels. The function of the outer ball cage is both power output and vehicle turning.
Outer ball cage: The steel balls of this kind of ball cage are fixedly placed in the six windows of a cage between the star sleeve and the bell-shaped shell. The steel balls are located exactly half of the way in the star sleeve and the bell-shaped shell. The angle of action with the universal joint is determined at one time. The smooth surface treatment makes the universal joint move like a helical gear. The six steel balls push the fairways in their respective star sleeves and bell-shaped shells, but the torque is transmitted through the steel balls instead of the teeth of the gears.
1. When turning or driving on bumpy roads, the vehicle will make regular abnormal noises.
2. Observe the dust cover of the ball cage with naked eyes. If the dust cover is damaged or leaks oil. Since the lubricating grease in the dust cover is specifically designed to reduce ball head wear, oil leakage will cause the lubrication to decrease, and the ball head wear will increase, resulting in a larger gap and abnormal noise.
In addition to the above symptoms, we can raise the vehicle for inspection and dismantle it if necessary. After the vehicle is raised, hold the axle shaft tightly with your hands, and then turn it back and forth quickly. If you can feel an obvious gap, it means the ball cage is seriously worn. Or remove the half shaft and check whether there is excess clearance in the ball cage. In addition, if there are sand and stones in the ball cage, they should be replaced in time, otherwise it will have a serious impact on the entire transmission system.
