1. Describing a type of mechanical coupling#Noun that allows constant power to be transmitted through a variable angle.

Examples of Using CONSTANT-VELOCITY in a Sentence

• The relative movement between the wheels and the differential is achieved through the use of swinging driveshafts connected via universal joints (U joints), analogous to the constant-velocity (CV) joints used in front-wheel-drive vehicles.
• A constant-velocity joint (also called a CV joint and homokinetic joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase in friction or backlash) and compensates for the angle between the two shafts, within a certain range, to maintain the same velocity.
• The hard steering was attributed to not having constant-velocity joints for the front halfshafts and to unequal-length halfshafts without matching torsional characteristics.
• A Hobson's joint or Hobson's coupling is a type of right-angle constant-velocity joint; rods bent 90° are able to transmit torque around a corner because they are all free to turn in their mounting holes in both legs of the coupling.
