Glossary “torsional vibration” Definition:
1). A rotary vibration that causes a twist-untwist action on a rotating shaft. 2). Low frequency vibration that is produced by components while thay are under a twisting stain. Usually felt in the seats and floor of the vehicle and is heard as a rumbling sound. Most noticeable during steady, hard acceleration.
torsional strength
Glossary “torsional strength” Definition:
The property of a material that withstands a twisting force.
torsional stabilizer bar
Glossary “torsional stabilizer bar” Definition:
Stabilizer bar made of spring steel reduces the body roll, thereby reducing the effect of centrifugal force when a vehicle rounds a corner. Some stabilizer bars are hollow.
torsional springs
Glossary “torsional springs” Definition:
Round, stiff coil springs placed in the driven disc to absorb the torsional disturbances between the driving flywheel and the pressure plate and the driven transmission input shaft.
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.
torsional rigidity
Glossary “torsional rigidity” Definition:
Resistance of a structure to twisting and flexing.
torsional force
Glossary “torsional force” Definition:
Twisting force or movement, which if excessive can cause considerable damage to a transmission, or other driven components.
torsional balance
Glossary “torsional balance” Definition:
Term used for vibration damper.
torsion rods
Glossary “torsion rods” Definition:
Type of rod that when twisted, acts as a spring. Usually found attached to deck lid hinges to assisting in opening the deck lid.
torsion bar suspension
Glossary “torsion bar suspension” Definition:
A suspension featuring a torsion bar rather than a coil or leaf spring.
torsion bar steering gear
Glossary “torsion bar steering gear” Definition:
A rotary valve power-steering gear.
torsion bar spring
Glossary “torsion bar spring” Definition:
Term used for torsion bar.
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.
Torrington bearing
Glossary “Torrington bearing” Definition:
Common name for a radial, needle thrust bearing.
Torqueflite
Glossary “Torqueflite” Definition:
A three-speed, plus reverse, automatic transmission used by Chrysler.
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.
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 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-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 test
Glossary “torque test” Definition:
Starting motor test to determine torque produced and current required while the specified voltage is applied.
