Constant velocity universal joint (c.v.joint & c.v.axle) is a mechanism that connects two axes that are not coincident with each other and that transmits the two axes at the same angular velocity. It is an important component in the transmission system of a car. Its role is to transfer the power of the engine from the transmission to the drive wheels of the car to meet the requirements of the outer corner of the drive shaft of the car. The power of the engine is transmitted smoothly and reliably to the wheels; Suspension of the end suspension. Drive the car at high speed.
There are many types of constant velocity joints (cvjoint & cvaxle) used in cars. Among them, the most widely used ones are the CV joint (cvjoint & cvaxle) and tripod type constant velocity joints (cv). Joint & cvaxle), which consists mainly of sliding sleeves, three-way shafts, drive shafts, star sleeves, cages and bell-shaped shells. Due to the heavy driving torque transmitted by the constant velocity universal joint, with the heavy load, high transmission accuracy, large demand, and safety components, the main parts are all made of precision forgings.
Power for front-wheel drive vehicles is transmitted directly from the powertrain consisting of the engine, transmission and final drive to the front wheels. The front wheel is not only the driving wheel but also the steering wheel. The angle of deflection during steering is very large, with a maximum of 400 or more. At this time, it is not possible to use a conventional universal transmission shaft with a small deflection angle. This is because ordinary joints (c.v.joint & c.v.axle) produce large fluctuations in rotational speed and torque when the deflection angle is large. Therefore, constant velocity joint shafts with large deflection angle and uniform angular velocity must be used.
Constant velocity joint (cvjoint & cvaxle), English name: CVJoint (ConstantVelocityJoint) constant velocity joint, is the universal joint (cvjoint & cvaxle) that the rotational speed (angular velocity) of the master axis and the slave axis is equal . In front-wheel drive vehicles, the front axle is equipped with a constant velocity joint drive shaft (drive and steering).
