A sideshaft is a system that transfers power from a differential to the wheels allowing wheel, thus movement due to steering or suspension movement.
This system has three major elements:
Inboard Constant Velocity Joint (CVJ)
– Including lubrication and sealing system interconnecting shaft.
Outboard Constant Velocity Joint (CVJ)
– Including lubrication and sealing system
In most applications, the inboard CV joint is a plunge joint that allows the effective length of the sideshaft to adjust due to suspension movement. In front (or steer) axle applications, the outboard joint must transfer power effectively through wide range of angles (up to 52 degrees). In rear axle applications, joint operation angles are much lower.
