Chapter 42, Problem 1SA
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
Expert Solution & Answer
To determine
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.
