Unit 1 quiz review: powertrains
False
4WD driveline includes rear transaxle and center differential, rear differential and rear drive axles
True
4WD driveline includes transfer case, front and rear drive shafts and axle assemblies
Steel
High strength material commonly used to make gears
Gear Ratio
If the driving gear is smaller than the driven gear, torque increases
FWD drive train
Includes a transaxle with half shafts, and hub assemblies
AWD/4WD drive train
Includes a transfer case with front and rear differentials
RWD drive train
Includes a transmission, drive shaft, and differential
Bronze
Material used to make gears that can tolerate high loads
False
RWD driveline includes half shafts and center differential
Spur gears
Straight-cut teeth and make noise when operating
True
AWD driveline includes half shafts, drive shafts, center and rear differential, and rear drive axles
Manual transmission
Uses a clutch to engage the engine power to the transmission
CVT
Uses belt, pulleys, or pumps to change gear ratio
True
RWD driveline includes U-joints, drive shaft, and axle shafts
False
AWD driveline includes transfer case, two drive shafts, front, and rear differentials
Automatic transmission
Changes gears with little input from the driver
False
FWD driveline includes U-joints, axle shafts and a PTU
True
FWD driveline includes half shafts, transaxles, and CV joints
Plastic
Gears made from this material are not very strong and cannot withstand high temperatures
Technician A
Technician, a states of cars use RWD, FWD, a WD, and 4W D drivelines. Technician be says that the heavy equipment typically uses a FWD driveline
Helical gears
Teeth cut on an angle to evenly distribute the load across the gear tooth, making it quieter
Worn gears
Teeth of this gear are cut so they resemble screw threads
Bevel gears
Teeth of this gear are mounted at a 90-degree
Half shafts
The differential assembly transfers torque to the
Hub Assembly
The half shaft transfers torque to the
Drive shaft
The transmission output shaft transfers torque to the
Gear trains
This is a set of gears that transfers torque
Gear Reduction
This is also known as torque multiplication
Drive shaft
Which component is located between the front and rear U-joint ?
Slip yoke
Which component is splined to the transmission output shaft ?
Differential assembly
Which component transfers power to the drive axles and half shafts ?
U-Joints
Which component transfers torque at varying angles to the drive shaft ?
Axle shafts
Which component transfers torque to the driving wheels ?
