Glossary “torsional force” Definition:
Twisting force or movement, which if excessive can cause considerable damage to a transmission, or other driven components.
t
torsional rigidity
Glossary “torsional rigidity” Definition:
Resistance of a structure to twisting and flexing.
torsional rings
Glossary “torsional rings” Definition:
Rings that have a slight twist when placed within the cylinder wall, made by adding a chamfer or counterbore on the ring.
torsion bar
Glossary “torsion bar” Definition:
A long, spring-steel bar replacing the coil springs, connected from the chassis to the lower control arm, to provide the necessary springing effect on the front suspensions by twisting rather than compressing or bending.
torsion bar spring
Glossary “torsion bar spring” Definition:
Term used for torsion bar.
torsion bar steering gear
Glossary “torsion bar steering gear” Definition:
A rotary valve power-steering gear.
torsion bar suspension
Glossary “torsion bar suspension” Definition:
A suspension featuring a torsion bar rather than a coil or leaf spring.
Torrington bearing
Glossary “Torrington bearing” Definition:
Common name for a radial, needle thrust bearing.
torque tube
Glossary “torque tube” Definition:
Drive shaft system that is enclosed in a tube extending from the transmission tailshaft to the rear-axle housing.
torque turn
Glossary “torque turn” Definition:
When a bolt is tightened to a specific torque and then turned an additional 35 to 180¡ã.
torque wrench
Glossary “torque wrench” Definition:
Wrench that indicates the amount of torque being exerted when used, to enable threaded parts to be tightened a specified amount.
Torqueflite
Glossary “Torqueflite” Definition:
A three-speed, plus reverse, automatic transmission used by Chrysler.
torque test
Glossary “torque test” Definition:
Starting motor test to determine torque produced and current required while the specified voltage is applied.
torque-to-yield bolt
Glossary “torque-to-yield bolt” Definition:
Bolt that has been tightened to a specified yield or stretch point. May need to be torqued in several steps. Must not be reused.
torque spec
Glossary “torque spec” Definition:
Force required to tighten a nut or bolt to specification.
torque steer
Glossary “torque steer” Definition:
An outside influence, such as uneven front tire-tread wear, causing the steering wheel to turn right or left during hard acceleration, relating to the dual torque and steering requirements that are applied to the drive axle of front-wheel-drive vehicles. When there are different length shafts, the long one wraps and there is a slight lag before it puts its torque to the wheel, causing the vehicle to pull to one side.
torque rod shims
Glossary “torque rod shims” Definition:
Thin metal shims used to rotate the axis pinion to change the operating angle of the U-joint.
torque sequence
Glossary “torque sequence” Definition:
Order in which a series of bolts or nuts should be tightened.
torque multiplication phase
Glossary “torque multiplication phase” Definition:
Period of torque converter operation when the vortex flow is redirected through the stator to accelerate impeller flow to the turbine and increase engine torque.
torque pattern
Glossary “torque pattern” Definition:
A tightening sequence that assures that parts are clamped down evenly by several bolts or nuts.
