Constant Velocity (CV) joints, crucial for front-wheel-drive and independent suspension systems, ensure smooth power transmission across varying angles.
The tripod joint represents a specific category of CV joints.
This joint comprises a three-roller spider affixed to the drive shaft, which is housed within a casing.
The three rollers are designed to move within internal grooves in the housing, permitting both axial displacement and angular articulation.
This configuration facilitates compensation for suspension movement and ensures uninterrupted power delivery.
In contrast, Rzeppa joints employ balls and a cage mechanism, rather than a spider and three rollers.
Terms like "flexible" or "rigid" do not denote distinct CV joint types.
Consequently, the appropriate designation is tripod.
