Cage, also called "constant velocity universal joint", is an important component in the car transmission system. Its function is to transfer the power of the engine from the transmission to the drive wheel to drive the car at high speed.
There are many types of constant velocity joints for cars. Among them, the ball cage type constant velocity joints and the tripod type constant velocity joints are mainly used for sliding sleeves, three-way shafts, transmission shafts and stars. The main components of the sleeve, the cage and the bell shell.
Because the constant velocity universal joint transmits heavy driving torque, the load is heavy, the transmission precision is high, the demand is large, and it is a safety part. Therefore, the main parts are processed by precision forgings.
Where is the cage in the car?
The way to find the position of the cage is: first lift the vehicle, find the drive wheel, find the drive shaft, with the rubber sleeve, the outer cage is close to the tire, and the inner cage is close to the transmission, which is a wearing part.
The composition of the outer cage:
Bell shell
2. Inner star wheel
3. Cage
4. Steel balls
5. Dust cover
6. Bundle
7. Grease (unlike normal butter, the main component is molybdenum disulfide).
Outer Cage: The steel ball of this cage is placed in six windows of a cage that is fixed between the star sleeve and the bell shell. The steel balls are exactly half in the star sleeve and the bell shell. The position, once to determine the angle of action of the universal joint, the smooth surface treatment makes the movement of the universal joint like a helical gear, and the six steel balls respectively push the respective star-shaped sleeve and the bellows in the bell-shaped shell. It's just that the torque is transmitted through the steel balls instead of the teeth of the gears.
The composition of the inner cage:
Bell shell
2. Trigeminal bearings or steel balls. (There are two separates here)
3. Dust cover
4. Bundle
5. Grease (unlike normal butter, the main component is molybdenum disulfide).
Inner Cage (Triple): The three-ball pin type constant velocity joint has no steel balls inside, but uses three bearings with needle rollers that can be slipped in three tracks in the bell casing. It is mainly used for the inner cage of the four-wheel drive. It is suitable for the position of the inner cage with a small torsion angle. It can slide inward and outward to adapt to the change of the length of the drive shaft when the vehicle is moving.
Inner Cage (Six-Pear): This type of slip-type constant velocity joint has a different design concept, in which the torque is transmitted by the steel ball in the inclined track, and the performance of the product is excellent, exceeding the TJ type. The ball cage, but the short distance of the slip, can solve the noise problem and is widely used on the four-wheel drive.
