torsion bar

[′tȯr·shən ‚bär]
(mechanical engineering)
A spring flexed by twisting about its axis; found in the spring suspension of truck and passenger car wheels, in production machines where space limitations are critical, and in high-speed mechanisms where inertia forces must be minimized.

Torsion Bar

 

a bar that operates by twisting and acts as a spring. Torsion bars are manufactured from heat-treated steel, which tolerates great torsional stress and twisting through large angles (tens of degrees). They are used mainly in vehicle suspensions and multistage reducers to equalize the torque between parallel gears.
