t
torque curve
Glossary “torque curve” Definition:
Graphic depiction of the amount of torque available at different engine speeds.
torque in steps
Glossary “torque in steps” Definition:
Three steps are normally used to reach the specific torque. The final step will always be the specific torque value. Each step must be done in the specific torque sequence.
torque limiting clutch brake
Glossary “torque limiting clutch brake” Definition:
System designed to slip when loads of 20-25 pounds-feet are reached, to protect the brake from overloading and the high heat damage.
torque multiplication
Glossary “torque multiplication” Definition:
Torque increase as a result of converter action that allows the turbine to revolve slower than the impeller during acceleration and heavy-load conditions at a ratio as much as 2:1.
torque converter capacity
Glossary “torque converter capacity” Definition:
Ability of a torque converter to absorb and transmit engine torque in relation to the amount of slippage in the converter.
torque converter clutch
Glossary “torque converter clutch” Definition:
Clutch located inside the torque converter that locks the turbine and the impeller together to prevent any slippage. Also called a lockup torque converter.
torque converter valve
Glossary “torque converter valve” Definition:
Valve in the transmission control system which limits the amount of pressure that is fed to the torque converter.
torque boxes
Glossary “torque boxes” Definition:
The structural parts of the frame designed to allow some twisting to absorb road shock and collision impact.
torque converter
Glossary “torque converter” Definition:
1). Unit that transfers power from the engine to the transmission input shaft by directing and redirecting fluid flow. 2). A type of fluid coupling used to connect the engine crankshaft to the automatic transmission input shaft. Torque converter multiply the available engine torque under certain operating conditions.
torch shrinking
Glossary “torch shrinking” Definition:
Uses the heat of an oxyacetylene to torch to release tension in a panel.
torching
Glossary “torching” Definition:
To flame-cut metal.
torque
Glossary “torque” Definition:
1). Measure of a force-producing tension and rotation around an axis. 2). Twisting force which may or may not result in motion.
torque and twist
Glossary “torque and twist” Definition:
The forces developed in the vehicle and/or frame that are transmitted through the vehicle, is required to negotiate bumps, such as street curbs.
topcoat
Glossary “topcoat” Definition:
Usually the final paint film applied to a surface.
topcoat removal limit
Glossary “topcoat removal limit” Definition:
When making repairs on topcoats, no more than ? mil of clearcoat should be removed to maintain film intrgrity and durability on basecoat/clearcoat finishes, and no more than ? mil of clearcoat should be removed on single-stage finishes. When these limits are exceeded, appropriate clorcoat repairs are required.
