Examples of how to use “torsion bar” in a sentence from the Cambridge Dictionary Labs Some vehicles use torsion bars to provide automatic levelling, using a motor to pre-stress the bars to provide greater resistance to load and, in some cases (depending on the speed with which the motors can act), to respond to changes in road conditions. In most cars with this type of suspension, swapping torsion bars for a different spring rate is usually an easy task. Pre-loading puts a specified amount of tension on the bar to support the weight of the vehicle and ensure proper height while the vehicle is at rest. In most torsion bar systems, ride height (and therefore many handling features) may be changed by simply adjusting bolts that connect the torsion bars to the steering knuckles. Its first use in a passenger car was in 1966, starting with the E-platform vehicles (Oldsmobile Toronado, Cadillac Eldorado), 4 wheel drive S-10 pickups & Astro vans with optional all-wheel drive, and since 1988, full size trucks and SUVs with four wheel drive (GMT400, GMT800, and GMT900 series). This stepped piece rests on a large bolt which contacts the bottom edge and adjusts the amount of tension and pre-loads the bar. These bars do this by absorbing some of that force by moving with the bumps rather than acting in opposition to them. The system was applied to many new combat vehicle designs during the Second World War. The durability of the torsion bar as well as the ease of adjustment have combined to make it a very well received addition to many truck lines. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. [1] The Czechoslovakian Tatra cars designed by Professor Hans Ledwinka in the mid-1930s used all round independent torsion bar suspension, along with air cooled rear engines. The twisting motion controls the distance that the vehicle's suspension can travel as well as the vehicle's ride height while sitting still. In automobiles a torsion bar is a long spring-steel element with one end held rigidly to the frame and the other end twisted by a lever connected to the axle. Turn the torsion bar bolt counterclockwise to lower the vehicle. [2] Needing bars longer than the width of the tank to get the required spring rate and maximum elastic bend angle from available steel alloys, designer Professor Ernst Lehr created a suspension that effectively folded the bars in half. Drehstabfedern können zylindrischen oder anderen Querschnitt haben, rechteckige können gebündelt verwendet werden, z.

Manufacturers change the torsion bar or key to adjust the ride height, usually to compensate for heavier or lighter engines. The coil-spring suspension of the T-38 was replaced by a modern torsion-bar suspension with four pairs of road wheels. It was used extensively in European cars Renault, Citroën and Volkswagen, as well as by Packard in the 1950s. 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. Because the torsion beam acts in the lateral plane, not vertically, the twist beam axle cannot provide ride height adjustment, and it suffers, to some extent, similar car handling limitations as other beam axle suspensions. Torsion bar, rod or bar that resists twisting and has a strong tendency to return to its original position when twisted.
