how does torsion bar suspension work
It’s called a torsion bar. Now, in the context of 1950s-60s American barges quite what they mean by 'well' is open for discussion, but using shocks to make up for springing problems is by no means a dead art even now. Jan Zuijdijk (of JRZ fame) has a book that he put out through Race Tech Magazine. frequency.

The more tightening applied to a torsion bar's bolt/key, the firmer the ride. When one end of the torsion bar is affixed to an object that cannot be moved, the other end of the bar is twisted, thus causing torque to build up. They minimize the force of bumps and holes in the road felt by the car's occupants. Did they include graphs? Longitudinal torsion bars extend under the passenger compartment, cutting into interior space by raising the floor, while in transverse systems, torsion bar length is limited by vehicle width. As the wheel passes over a bump the bar twists. My apologies!! How to check and change your car’s auxiliary drive belt. This is where the shock absorber, or damper, comes in. The torsion bar keys are turned to apply the twist necessary to adjust vehicle ride height. So we compensate for non perfect corner frequencies (which were a stab in the dark anyway) by changing the shock tune.
This affects the car’s ride and handling, and accelerates tyre wear. There are some elements of a modern anti pitch F! So it's not all bad...... Find below some pictures of the torsion bar suspension I incorporated into my Kurtis replica speedway car. Its chief virtue is simplicity and a lower price. Twist-beam rear suspensions were pioneered on the Volkswagen Golf[citation needed] in the early 1970s, and remain common on compact cars and minivans. The revolutionary Jaguar E-Type introduced in 1961 had a torsion bar front suspension very similar to the Citroen and Morris Minor, and an independent coil spring rear suspension using four shock absorbers with concentric springs. Another type of spring doesn’t actually look like a spring at all. On some vehicles, the CV joints can wear prematurely if the ride height is over adjusted. A disadvantage is that torsion bars, unlike coil springs, usually cannot provide a progressive spring rate. This is not recommended for shared computers. As each air spring moves up or down, the system removes or adds air to maintain comfort and reduce body lean in corners. Named for the General Motors engineer who designed it, this independent suspension system takes the form of a damper inside a coil spring. The top section is called the outer tube. Pretty easy to work on. You currently have javascript disabled. It's more of a thing where it seems to work, but I'm curious at what point it won't. Haynes shows you how on YouTube: Mk1 Ford Focus, Haynes shows you how on YouTube: Volkswagen Polo. By coiling the wire instead of having it straight makes it more compact and obscures the similarity between the two. Page 1 of 2 - How does a torsion bar suspension work?
Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota. The main difference is how the load is fed into the spring to create the torsion. There are a lot of videos on YouTube explaining them such as this one: https://www.youtube....h?v=huWNurDnGB8. A typical longitudinally designed torsion bar is a long steel bar fitted between the frame of the vehicle and one of the control arms. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. It is also a possibility that the adjuster bolts may have been wound too far. Because they have "give," the torsion bars minimize the impact of road bumps, and the car passengers stay more comfortable. They are also used in the front suspension of the 914 as well as the rear suspension of the 924, 944, and 968. The flexibility of the spring is the main reason that a torsion bar is used. Hi Greg. It permits greater independent movement than an axle but not as much as a fully independent system. Whatever the type of damper, its job is to release the spring’s energy in a controlled manner. For example, magnetic dampers are filled with a ferrous fluid. Mind you, the 72 did win a lot of races so on that basis well worthwhile. It is interconnected like a 2CV or BMC 1100 and has self levelling too. If you get really clever and put a third spring element in the middle of the AR bar you can control all three motions, bump, roll and heave almost independently. Many contemporary main battle tanks use torsion bar suspension, including the American M1 Abrams,[3] German Leopard 2,[4] and Chinese MBT-3000,[citation needed] though the newest generation of tanks such as the Russian T-14 Armata utilize an adjustable hydraulic suspension. I hadn't noticed the year 2000 date! Some cars, such as the Volkswagen Golf S Mk 7, have a halfway version at the rear called twist beam rear suspension. This has to take a lot of stress and have a long fatigue life. 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. Panhard did a similar thing with three torsion bars but used simple bars linked by a sort of steel doughnut at the inner end. 23 videos FREE with every online Peugeot 208 Workshop Manual!
Check the vehicle's wheel alignment, because changing a vehicle's ride height affects several steering angles. I may never be able to show my face here again. The meat in this particular sandwich are the ride guys, at the cost of making our life more difficult we can keep everybody else happy. I believe Classic Team Lotus still has a large stock of the original bars as getting new ones made is mega expensive. and am suffering the shame of being a torsion bar ignoramus. When the car hits a bump, the suspension moves, causing the bar to twist and absorb the energy. Nathan, try wikipedia https://en.wikipedia..._bar_suspension.
I have had the misfortune over the years to have driven that buggy, an early Holden with a broken front shock and a broken rear shock and recently my Supermodified with a broken l/r shock on a torsion bar set up. The top of the damper is attached to a so-called suspension turret (visible when you lift the bonnet).
Twisting motion of the bars, rather than compression of springs, provided the cars with soft but stable suspension. What sort of springing problem would/could not be rectified in the production line Greg? After making a change to the height of the torsion bar, it is a good idea to have the alignment of your vehicle checked to make the sure the weight of the vehicle body is properly distributed. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsionresistance. 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.
