303b

Question 1

The 3 V’s of energy transfer?

Answer 1

Volume
Velocity
Viscosity

Question 2

What is an impeller?

Answer 2

Impeller receives torque from the engine flywheel and delivers oil to the turbine

Question 3

Advantages of fluid couplers?

Answer 3

No mechanical connection

Shock absorption

Gradual start up of load

Question 4

Disadvantages of fluid couplers?

Answer 4

Efficiency is lost due to slippage.

Question 5

What is vortex flow?

Answer 5

This occurs when the turbine is spinning at a lower rpm than the impeller. Accompanied by high heat, low output speed and high torque. Also called converter phase

Question 6

What is rotary flow?

Answer 6

When the impeller and the turbine are spinning at the same speed, creating a coupling effect. Also known as coupling phase

Question 7

What decides flow in a torque converter?

Answer 7

The transmissions resistance to flow

Question 8

What is the purpose of a split guide ring?

Answer 8

Prevent turbulence within the unit while it is in operation

Question 9

The impeller is sometimes called?

Answer 9

Pump

Question 10

What’s the turbine?

Answer 10

Converts the kinetic energy in the fluid into mechanical energy. The mechanical energy is transmitted to the driveline

Question 11

What’s the stator?

Answer 11

Also called the reaction member, is designed to change the direction of the oil flow so that it assists in torque multiplication

Question 12

What are the two types of stators?

Answer 12

Fixed

Freewheeling

Question 13

What are lockup clutch’s?

Answer 13

The lockup clutch mechanically connects the turbine and the impeller giving a true 1:1

Question 14

What are phases?

Answer 14

Phases refer to the relationship between the impeller and turbine relative to energy transfer.

Converter, coupling, lockup

Question 15

What are stages?

Answer 15

Stage refers to the number of times the oil strikes the turbine before it returns to the impeller

Question 16

Variable capacity torque converters

Answer 16

Multi impeller

Multi turbine

Variable pitch stator

Question 17

Multi impeller converters?

Answer 17

Both impellers locked together for high torque and one released and free wheels for light work

Question 18

Multi turbine?

Answer 18

Use two turbines that are connected together by an overrunning clutch

Question 19

Where does oil go directly after the torque converter?

Answer 19

Oil cooler

Question 20

What is the purpose of an outlet relief?

Answer 20

Keeps the converter full of oil

Question 21

Dry housing characteristics?

Answer 21

No pto, torque converter is sealed so no oil leaks into the housing

Question 22

Wet type converter?

Answer 22

Uses oil to line gear train in housing for a pto or scavenge pump.

Question 23

Scavenge methods?

Answer 23

Gravity drain

Scavenging pump

Question 24

Functions of a torque divider?

Answer 24

Provide automatic clutching

Multiply engine torque

Absorb power train shock loads

Question 25

The prime mover in a torque divider is connected to what?

Answer 25

Sun gear

Question 26

Output shaft in a torque divider is connected to what?

Answer 26

Planetary carrier

Question 27

Converter mounting options?

Answer 27

Engine mount Remote mount

Question 28

When are stall tests generally conducted?

Answer 28

Highest gear

Question 29

What could be happening with a slipping 1 way clutch on a stator?

Answer 29

Low stall speed

Question 30

What must you check after installing a torque divider/converter?

Answer 30

Crankshaft endplay
