CV Joint (Constant Velocity Joint) for Driveshaft

A driveshaft CV joint (constant velocity joint) is a mechanical part that helps transfer power from a vehicle's engine to its wheels smoothly and at a constant speed, regardless of the angle of the driveshaft.
It is made up of two parts connected by steel balls and can wear out over time.

-Signs of a failing CV joint include clicking noises while turning and vibrations while driving.

驱动轴CV接头是车辆传动系统中的机械部件，可使动力从发动机平稳地传输到车轮，而且无论驱动轴的角度如何都能以恒定速度传输。它通常位于驱动轴末端，有助于实现连续的动力传输。
CV接头由内部环和外部环两个主要部件组成，两者之间由钢球连接。内部环与驱动轴连接，而外部环与轮毂连接。随着驱动轴的旋转，钢球沿着环滚动，实现平稳的动力传输，即使驱动轴由于路面颠簸而上下移动也不会影响传动效果。CV接头对于前轮驱动车辆以及许多全轮驱动车辆至关重要，会随着时间的推移而磨损

-CV接头失效的迹象包括转弯时出现点击声或爆裂声，加速或高速行驶时出现振动以及从接头处泄漏润滑油。及时更换失效的CV接头非常重要，以防止对传动系统造成进一步损坏。
