Section type: RF + AAR

Advantages: The AAR profile of the moving section can well avoid the aggravation of the wear of the ordinary section when the swing angle is higher than 5.5 °, which improves the life of the drive shaft of the SUV and off-road vehicle .

product description:

AAR constant speed drive shaft assembly also has a name --- efficient drive shaft. This section is a drive shaft designed to adapt to today's high chassis cars and SUVs. The maximum working angle can reach 26 °, and the normal angle is> 5 °. When the car has a high chassis, the normal working angle of the drive shaft will increase. When the normal working angle of the ordinary joint reaches 5 °, the axial derived force and high-frequency slip resistance of the drive shaft will increase. In other words, there will be noise and jitter in the car. By improving the internal bearing structure at the sliding end, the AAR joint can reduce the friction between the ball ring and the ball cage, thereby reducing the source of noise and then achieving the effect of noise reduction.
