Chapter 7 Homework Differentials Flashcards
When discussing differential action,
Technician A says that when a car is making a turn, the outside wheel must turn faster than the inside wheel.
Technician B says that a locked differential may cause the car to slide around a turn.
Who is correct?
Both A and B
When discussing the torque multiplication factor of a rear axle,
Technician A says that all of the gears in a differential affect torque multiplication.
Technician B says that there is a gear reduction as the power flows from the pinion to the ring gear.
Who is correct?
B only
When discussion rear axle operation,
Technician A says that when a car is moving straight ahead, all differential gears rotate as a unit.
Technician B says that when a car is turning a corner, the inside differential side gear is locked to the differential case, causing the outside side gear to rotate faster.
Who is correct?
A only
When discussing the mounting of the drive pinion shaft,
Technician A says that drive pinion shafts may be mounted in a long bushing.
Technician B says that drive pinion shafts are held by two tapered roller bearings.
Who is correct?
B only
When discussing numerical final drive gear ratios,
Technician A says that lower gear ratios allow for better acceleration.
Technician B says that higher gear ratios allow for improved fuel economy but lower top speeds.
Who is correct?
Neither A nor B
When discussing different types of ring and pinion gear sets,
Technician A says that with a hunting gear set, each tooth of the pinion will always return to the same few teeth on the ring gear each time the pinion rotates.
Technician B says that when a nonhunting gear set rotates, any pinion gear tooth is likely to contact each and every tooth on the ring gear.
Who is correct?
Neither A nor B
When discussing electrohydraulic limited-slip differentials,
Technician A says that these differentials improve handling on slippery surfaces.
Technician B says that these differentials limit the amount of differential action between the side gears.
Who is correct?
Both A and B
When discussing the different designs of rear axles,
Technician A says that the bearings for full-floating shafts are located within the axle tubes of the rear axle housing.
Technician B says that C-type retainer axles are held in place by a pressed retainer ring against the axle bearing.
Who is correct?
Neither A nor B
When discussing differential lubricants,
Technician A says that limited-slip differentials require a special lubricant.
Technician B says to fill the differential approximately one inch below the opening to avoid foaming.
Who is correct?
A only
When discussing gear ratios,
Technician A says that they express the number of turns the driven gear makes compared to one turn of the drive gear.
Technician B says that the gear ratio of a ring and pinion set expresses the number of teeth on the ring gear divided by the number of teeth on the pinion gear.
Who is correct?
B only
