The Adjusted Angular Roller (AAR) joint uses a tripod plunging design suitable for the inboard gearbox joint of a constant velocity sideshaft for most vehicles. The low plunging resistance and low axial forces of the AAR tripod plunging joint deliver NVH refinement, making it appropriate for high working angles. It has a maximum articulation angle of 26 degrees and 50mm plunge.
The AC (Angular Contact) is a fixed ball joint suitable for passenger cars and light vehicles. Providing a maximum articulation angle of 47 degrees to meet the criteria for steering and suspension movement, it is the most popular choice for the wheelside of a constant velocity sideshaft.
AYC systems allow individual driving torque distribution to the wheels of a driven axle to generate a YAW-Moment in the vehicle to support steering action and improve the stability and agility of a vehicle at the same time.
This system is also known as Full Time Four Wheel Drive. The transfer case or Power Transfer unit provides a fixed torque distribution to the front and rear axles via a centre differential.
This is the angle between inclined shaft axes.
