[1] Also in the 1930s, prototypes of the first Volkswagen Beetle incorporated torsion bars—especially their transverse mounting style. At a time when the mechanics of stress and metal fatigue in monocoque body frames was poorly understood, torsion bars were very attractive to vehicle designers as the bars could be mounted to reinforced parts of the central structure, typically the bulkhead. The bar absorbs impact because only one end of the bar is attached; the other is left free to move with the car's bumps. General Motors first used torsion bars on their light-duty pickup trucks in 1960 until it was phased out in 1963 where traditional coil springs are used up front for their 2WD trucks. A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. Height adjustable suspension has been used to implement a wheel-change mode where the vehicle is raised on three wheels so that the remaining wheel is lifted off the ground without the aid of a jack.

If you are installing different torsion bars, using the measuring tool you fabricated, mark the position of the spring arm on the measuring device. A disadvantage is that torsion bars, unlike coil springs, usually cannot provide a progressive spring rate. The torsion beam functions both as wheel locating arm and as an anti-roll bar to resist lateral motion of the wheels as the body leans in turns. The main advantages of a torsion bar suspension are soft ride due to elasticity of the bar, durability, easy adjustability of ride height, and small profile along the width of the vehicle. 2wd, with torsion bar, 1500 series.

Due to the massive weight of a main battle tank, compared to an automobile, there is a much greater risk of breaking a torsion bar on sudden bumps or maneuvers, and if it is not replaced in short order the reduced suspension can affect the maneuverability of the vehicle, and in extreme cases risk immobilizing the vehicle as the reduced capacity of the suspension causes additional torsion bars to break. Torsion Bar Suspension The torsion bar is basically a length of metal rod anchored at one end to the car body and at the other end to the suspension lower link. Some front-wheel drive automobiles use a related type of torsion beam suspension, usually called a twist-beam rear suspension, in which the rear wheels are carried on trailing arms connected by a laterally mounted torsion beam, as found on the Mitsubishi Debonair.
