Question

When discussing CV joints, Technician A says that they are called constant-velocity

joints because their rotational speed does not change with their operational angle. Technician B says that conventional universal joints cannot operate properly at the angles needed in a FWD axle arrangement.
Who is correct?
A: A only
B: B only
C: Both
D. Neither

Answer 1

A only is correct.

Constant-velocity joints are able to transfer torque with zero angular velocity variation and near-zero vibration to the drive wheels at a constant rotational speed, while still accommodating the up-and-down movement of the suspension. In most cases, they are used in front wheel drive vehicles.
