What appearance is universal joint when it was broken?

The symptoms of a broken directional double u joint half shaft are:

1. The universal joint is broken running straight road will appear cough cough sound, the universal joint is broken steering willdouble universal joint half shaft best-Xinsanming appear tap-tap-tap-tap-tap-tap sound. In severe cases, the car will not go;

2. The function of the universal joint on the car: the universal joint is the component that realizes the power transfer between the rotating shafts at different angles. Cross - shaft rigid universal joint is more commonly used in automobile rigid universal joint. The cross shaft rigid universal joint is simple in structure, reliable in operation, and allows a large Angle of intersection between the two shafts specially connected. It is most commonly used in automobiles. Construction and lubrication, constant speed conditions for cross - shaft universal joint drive. Double universal joint drive;

3. The Angle α1 between the two axes of the first universal joint is equal to that of the second universal joint. The driven fork of the first universal joint and the active fork of the second universal joint are in the same plane;

4. Quasi constant speed universal joint and constant speed universal joint, allowing a large Angle between shafts, bearing sealing, high efficiency, simple manufacturing process, convenient processing, reliable work and so on. Used mostly for off-road vehicles.

The reason why the double u joint half shaft is broken

1. Oblique imprint, when the total circumference clearance of the bearing in the universal joint cross shaft assembly is quite large, the needle roll is prone to skew phenomenon, so it will make the cross shaft between the journal and the axis of a certain Angle of imprint;

2. Fatigue spalling, the radial clearance between the cross shaft and the bearing gradually expands due to wear, and the load is concentrated. Fatigue indentation is caused where the load is quite large, and large area of fatigue spalling eventually occurs;

3. Lack of oil ablation, improper or insufficient lubricating oil, affecting the universal joint cross shaft assembly in the use of too high temperature, so that the bearing and journal appear bite phenomenon, damage needle roller and sealing parts, and finally make the ring surface ablation phenomenon; Needle or gasket failure.
