Consider the following statements regarding torque converter:
1. It has a stationary set of blades in addition to the primary and secondary rotors.
2. it can be used for multiplication of torques
3. The maximum efficiency of a converter is less than that of a fluid coupling
4. In a converter designed to given a large increase of torque, the efficiency ......... speed ratio approaches unity.
Of these statements
Option (A)
1, 2, 3 and 4 are correct
Option (B)
1, 2 and 3 are correct
1, 2 and 4 are correct
3 and 4 are correct
Correct Option:
Question Solution:
Torque convertors
It is a hydrodynamic power transmission device analogous in function to that of a mechanical gear box. It is used to transmit power from the driver shaft to the driven shaft while augmenting the torque on the driven shaft. It is used to multiply or reduce the torque shaft. It is used to multiply or reduce the torque available. it is designed which utilize two or more sets of turbine runners and fixed guide vanes, the fixed vanes being located between the turbine runners the efficiency converter is better at smaller speed ratio than that of the hydraulic coupling
