Alfred H. Rzeppa was an engineer working at Ford who invented a version of constant velocity joint in 1926. He proposed an improved design in 1936. An engineer is someone who practices the engineering profession; a professional practitioner of engineering; someone who uses scientific knowledge to solve practical problems and produce goods for society. ... Ford may mean a number of things: A ford is a river crossing. ... Cross-section through a typical outer CV joint (Saab 96) Constant Velocity Joints or CV joints allow a rotating shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. ...
It uses six balls, and an inner and outer race to provide constant velocity torque transfer regardless of the joint angle. The joint works something like a bevel gear with the balls bisecting the joint angle and functioning as the "teeth" to transmit torque.
A constant velocity joint is one that provides consistent velocity regardless of the operating angle of the joint.
A disc shaped type of inner CV joint that uses balls and V-shaped grooves on the inner and outer races to accommodate the plunging motion of the halfshaft.
A type of CV joint invented and introduced in 1926 by AlfredH. eppa.
