Application
Examples of the torque tube were the American cars of the Ford brand up through 1948, which used the less expensive transverse springs that could not take the thrust.
Buick started using coil springs in the 1930s, as did Nash's 1941 '600' model; these also necessitated using a torque tube. American Motors (AMC) also continued to use a coil spring rear suspension design with a torque tube on their large-sized cars (Rambler Classic and Ambassador) through the 1966 model year. The 1961-1963 Pontiac Tempest incorporated an unusual curved “torque-tube” with a 4-inch drop (about 10 centimeters) that housed a 3/4 inch (2 cm) solid steel driveshaft (nicknamed the "rope shaft") without universal joints on each end. The main purpose was to make the floor lower, thus increasing the car's interior room. The Peugeot 504, Peugeot 505, (except estate/station wagons) and the Volvo 300 Series also used a torque tube.
The torque tube driveline is also used in Sprintcars and Midget cars. The C5 and C6 Chevrolet Corvette, Lexus LF-A, Porsche 924, Porsche 928, Porsche 944, Aston Martin DBR9, Aston Martin DBS, Aston Martin DB7, Maserati Quattroporte V, Maserati GranTurismo and the Mercedes-Benz SLS AMG also use variations on this design, mostly with rear-mounted transaxles.
The Czech made Tatra truck is the only full size truck using a torque tube and independent suspension on all wheels.

Famous quotes containing the word application:
“There are very few things impossible in themselves; and we do not want means to conquer difficulties so much as application and resolution in the use of means.”
—François, Duc De La Rochefoucauld (1613–1680)
“Great abilites are not requisite for an Historian; for in historical composition, all the greatest powers of the human mind are quiescent. He has facts ready to his hand; so there is no exercise of invention. Imagination is not required in any degree; only about as much as is used in the lowest kinds of poetry. Some penetration, accuracy, and colouring, will fit a man for the task, if he can give the application which is necessary.”
—Samuel Johnson (1709–1784)
“It would be disingenuous, however, not to point out that some things are considered as morally certain, that is, as having sufficient certainty for application to ordinary life, even though they may be uncertain in relation to the absolute power of God.”
—René Descartes (1596–1650)
