Torsion bar is a tube or bar and acts as a spring, it replaces the conventional coil spring. Torsion bars are made of metal (generally some form of steel) with shorts splined ends to connect to the rocker on one end, and chassis on other.
Major Role
The torsion bar is mainly used in suspension system because of its durability, easy adjustability of ride height, and small profile along the width of the vehicle. It takes up less of the vehicles interior volume than coil springs. Torsion bars reached the height of their popularity on mass production road cars in the middle of the 20th century at the same time that unitary construction was being adopted.

Part Description
From Wikipedia, the free encyclopedia Jump to:navigation, search A torsion bar with no load applied. A torsion bar with a load applied. A front VW beetle suspension crossectionA torsion bar suspension, also known as a torsion spring suspension or incorrectly torsion beam, is a general term for any vehicle suspension that uses a torsion bar as its main weight bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, mounted perpendicular to the bar, that is attached to a suspension arm, spindle or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, diameter and material.
