Chapter 5 homework CV Shafts Flashcards
When discussing CV joints,
Technician A says that they are called constant-velocity joints because their rotational speed does not change with their designed operational angle.
Technician B says that conventional universal joints cannot operate properly at the angles needed in a FWD axle arrangement.
Who is correct?
Both A and B
When trying to decide which is the most commonly used type of CV joint,
Technician A says that the ball-and-socket type is the most common.
Technician B says that the Rzeppa type is the most common.
Who is correct?
Both A and B
When discussing the differences between RWD and FWD front-wheel bearings,
Technician A says that most FWD cars use one tapered roller bearing, whereas RWD cars use two.
Technician B says that most FWD front bearings are pressed onto the spindle end of the drive axle.
Who is correct?
Neither A nor B
When discussing Rzeppa CV joints,
Technician A says that the inner race of the joint is connected to the drive axle.
Technician B says that the ball bearings rotate on a trunnion within the outer housing.
Who is correct?
A only
When explaining torque steer to a customer,
Technician A says that joints on the longer axle shaft operate at less of an angle than the shorter axle shaft.
Technician B says that cars with more powerful engines tend to have more torque steer issues.
Who is correct?
Both A and B
When discussing the purposes of the protective boot on a CV joint,
Technician A says that the boot prevents contamination of the joint’s lubricant.
Technician B says that a manufacturer can specify boots of silicone or thermoplastic materials to withstand severe operating conditions.
Who is correct?
Both A and B
When discussing the differences between the various designs of CV joints,
Technician A says that most joints use the tripod design and all are basically inter changeable.
Technician B says that the fixed tripod-type joint uses needle bearings, not ball bearings like the ball type.
Who is correct?
B only
Which of the following statements about FWD drive axles is not true?
Select one:
a.The outer part of each drive axle is supported by a steering knuckle.
b. The drive axle assembly comprises three pieces attached together in such a way as to allow the wheels to turn and move with the suspension.
c. A short spindle shaft runs from the outer CV joint to mate with the wheel assembly.
d. Half shafts operate at angles as high as 40 degrees for suspension travel and 20 degrees for turning.
Half shafts operate at angles as high as 40 degrees for suspension travel and 20 degrees for turning.
While discussing the ways manufacturers try to reduce the effects of torque steer,
Technician A says they sometimes use a combination of solid and hollow axles to help control torque steer.
Technician B says some manufacturers divide the longer shaft into two pieces: one piece comes directly out of the transaxle and is supported by a bearing. The other piece is a half shaft made to the same length as the axle on the other side of the car.
Who is correct?
Both A and B
While discussing FWD drive axles,
Technician A says the axle shaft is connected to the differential by a fixed CV joint.
Technician B says the axle shaft extends from the differential to a plunge CV joint on the wheel end.
Who is correct?
Neither A nor B
