Designing of Double Arc of the Ball Channel,that thestress points are point A and point B.The reason ofdouble arc design because When the vehicle is startedor braked, the gap between the steel balls and theball channels will cause the steel balls to move.
lf there is no stress point contact between the steel ball and the channel,it will lead to abrasion of the steel ball surface and the channel surface.
The double arc design changes the surface to surface contact to pointto pointcontact, reducing the abrasion of ball channel and steel ball effectively,and improving the service life of C.V.Joint and Drive shaft.
