While discussing the CVT transaxie used in Toyota hybrid vehicles: Technician A says that the transaxie contains two electric motor/generators, a differential, and a simple planetary gearset. Technician B says that the planetary gearset adjusts the diameter of the pulleys to provide the various speed ratios. Who is correct?
a. Technician A only
b. Technician B only
c. Both A and B
d. Neither A nor B
The correct technician among the two i.e. A and B who are discussing about CVT transaxle used in Toyota hybrid vehicles.
Answer to Problem 1SA
The correct answer is option (a) i.e. Technician A.
Explanation of Solution
The statement given by technician A, the transaxle used in Toyota hybrid vehicles is comprised of two electric generators, a differential, and a simple planetary gearset, is correct, as the CVT transaxle of hybrid vehicles contains these things only. Hence, technician A is correct.
The statement given by technician B, the diameter of the pulleys is adjusted by the planetary gearset to provide many speed ratios, is not correct, as the various speed ratios are provided when there is a change in the torque which is applied to the gearsets. Hence, technician B is not correct.
Conclusion:
Thus, the statement given by technician A is correct.

- While discussing AWD systems: Technician A says that some systems are electronically controlled and use an electromagnetic clutch to engage and disengage the drive axles. Technician B says that some cars do not use a transfer case, but they are equipped with a third differential unit. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardWhich of the following would not cause noise while driving in 2WD under a heavy throttle? a. Faulty ignition switch b. Worn transfer case clutch c. Inoperative locking hubs d. Bad front half shaftarrow_forwardTechnician A says that if a drive belt does not have the proper tension, it may produce squealing and chirping noises. Technician B says belt tension should be checked even if the engine has an automatic belt tensioner. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- Technician A says that some AWD systems have a center differential. Technician B says that some AWD vehicles have a viscous clutch. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardSome CVT transaxles do not have torque converter. What is used is its place? A. A flywhell with a start cluth B. A flywheel with a regular clutch assemlby C. A viscous coupling D. A multiple-disc clutcharrow_forwardTechnician A says a purpose of a lockup piston clutch is to improve fuel economy. Technician B says a lockup piston clutch is designed with a damper assembly to transmit driving torque and absorb shock. Who is correct?arrow_forward
- Technician A says that the clutch-style limited slip differential uses a multi-plate clutch pack between each side gear and the differential case. Technician B says that if the clutch discs are worn, rotating torque will be higher than specifications. Who is correct?arrow_forwardwhen discussing shift problems, technician A says that worn or broken engine and transaxle mounts can cause a transaxle to have shifting problems. technician b says that poor shift boot alignment can cause a transaxle to jump out of geararrow_forwardWhen the input and output shafts are turning at the same speed, the transmission is in ____ drive.
