Full Range and Cheapest Parabolic Leaf Springs

20/02/17

What is a parabolic spring?

Basically a Parabolic Spring is a spring that consists of two or more leaves. The leaves touch only in the center, where they are fixed to the axle and at the outer ends, where they are fixed to the vehicle. In between those two points the leaves do not touch each other as they do with conventional leaf springs.

Each leaf represents a complete spring in it’s self and will act as such. To enable this the leaf is tapered, from the center (thick) to the outer ends (thin). This tapering is parabolic, it means that every centimeter (or inch) the thickness of the leaf decreases in an amount that relates to the square function of it’s length.

Above: Tapering in an “ideal” mono leaf spring. You can see that one leaf has a similar shape as a multi-leaf spring.
Below: You can see the tapering in the leaves of the spring. The leaves taper from the center till the end (eye) and are separated by distance blocs to prevent contact.

This may sound complicated but in fact it is very simple. Every single leaf will have, more or less, the shape of a
complete multi leaf spring and thus it’s capable to cope with the same forces. This means that the ideal parabolic spring could have only one leaf, however, this type of “mono leaf” spring will have very limited articulation/weight ratio due to high internal stresses so a 2 or 3 leaf parabolic spring can divide the stresses more evenly across the
other leaves and thus more axle movement is possible. That is why we designed 2 and 3 leaf springs. An other reason to increase the number of leaves on a parabolic spring is to increase the rate (load capacity). Because every leaf is one spring we can ad or take out leaves without compromising the strength of the leaf it self. So for example we have a 3 leaf rear spring and we ad one similar leaf the rate will go up for about 30% which means that the load capacity increases by +/- 30% (depending on the shackle effect)

Advantages of Parabolic Springs
Parabolic springs are leaf springs that consists of two or more leaves that only make contact in the center and at the outer ends. Each leaf in a parabolic springs is tapered to be thicker at the center and slowly thins out towards the ends. This is different from the conventional leaf springs wherein the leaves are in contact with each other and in which each leaf has uniform thickness from end to end.

Compared to conventional leaf springs, parabolic springs are able to resist more compression and have better flexibility. The flexibility results to better ride quality. The vertical speed movements are also easier to adjust with these types of springs. Due to the structure and components involved, parabolic springs are also lighter. This is an important factor when the priority is for maximum performance.
Another great application for parabolic springs is for off-road vehicles in which the flexibility of the spring is more effective in keeping the wheels always in contact with the ground compared to stiffer conventional springs.
The only downside to parabolic springs is that it has lesser capability when it comes to carry heavy loads. As such, these types of springs are used for when comfort is more preferred such as the cases with passenger buses. Only the coil springs are offer more comfortable than parabolic springs. However, coil springs which are often attached only to a single point of the chassis have the disadvantage when it comes to load distribution.
There are also newer developments with parabolic springs with brings it close to coil springs when it comes to comfort

Do Parabolic Springs require any maintenance?650-23-Parabolic--ZType-Leaf-Spring

A little light oil between the leaves will deter corrosion and prevent squeaks. The rubber bushings should be checked
occasionally. It is also very important to check that the ‘U’ bolts are torqued up to 70 ft lb. The ‘U’ bolt torque should be checked frequently under difficult conditions. You should also check that the shackles are tight by loosening the lock nuts and tightening up the shackle bolts. The condition of the axle buffers and check straps should also be checked occasionally.

I notice you use a larger rubber bushing in your spring eyes. Why is that?

Parabolic springs flex more than conventional springs and having an eye 18% larger allows us to use a bushing which can withstand flexure much better than a conventional one. The larger bushing also reduces stresses in the spring eye of the main leaf and insulates the Land Rover better from transmitted road noise.

Actualité de Kim Kardashian et ses deux demi-soeurs

18/01/17

Kim Kardashian et ses deux demi-soeurs, Kylie et Kendall Jenner, ont été photographiées lundi soir à New York, près du lieu de tournage de «Ocean’s Eight». Le film, dont la sortie est prévue en juin 2018, avait déjà fait parler de lui grâce à son casting prestigieux.

Les trois stars de «L’incroyable famille Kardashian» ont été aperçues quittant le tournage, habillées de robe de soirée. Le spin-off de la célèbre saga de Steven Soderbergh, «Ocean’s Eleven», mettra en scène la soeur de Danny Ocean, héros des précedents films, incarnée par Sandra Bullock. S’ajoutent au casting d’autres grands noms d’Hollywood, comme Cate Blanchett, Anne Hathaway, Helena Boham Carter, Sarah Paulson, et même la chanteuse barbadienne Rihanna.

Le choix de Kim Kardashian peut paraître surprenant puisque le film, réalisé par Gary Ross, tournera autour d’une équipe de braqueuses décidées à s’emparer d’un collier. Un clin d’oeil au braquage de bijoux vécu par la star de téléréalité à l’automne dernier, alors qu’elle séjournait dans un hôtel parisien.

De nombreuses apparitions

La scène dans laquelle Kim Kardashian et ses deux jeunes soeurs sont censées apparaître se déroule lors d’un Met Gala fictif. Rien de surprenant alors que la production ait fait appel aux trois jeunes femmes, habituées de ce genre d’événements.

D’autres célébrités devraient faire des apparitions pour, à l’instar des Kardashian, jouer leur propre rôle et crédibiliser la scène. Anna Wintour, la terrible rédactrice en chef de Vogue, et le créateur Alexander Wang participeraient eux aussi à ce spin-off.

Kim Kardashian de nouveau sur le devant de la scène

La star avait déjà fait son retour début janvier après plus de trois mois d’absence sur les réseaux sociaux. Les internautes avaient cependant remarqué un changement dans les choix esthétiques de la star, passant de clichés dénudés à des photos principalement axées autour de sa vie de famille.

Ce futur cameo marque le retour de la star sous les projecteurs. Ses apparitions au cinéma dans le passé se limitent à trois films : «Film Catastrophe» en 2008, «Deep in the Valley» en 2009 et «Tentation : Confession d’une femme mariée» en 2013. Elle a aussi joué son propre rôle dans des séries télévisées, comme «30 Rock» en 2012 ou «2 Broke Girls» en 2014.

Hard to Find Leaf Springs for Classices Cars at New Truck Spring

26/12/16

You may have heard of the old saying, “They don’t make them like they used to anymore!”

In part, this is quite true when it comes to the automotive industry. Earlier cars were considered a luxury for only the rich, and they weren’t mass-produced on the level that they are today. Resources were plenty and the demand for such vehicles for those who could afford it was substantial, but for today’s numbers, the ownership of classic cars are still quite low.

As a result, the materials used back then were heavier, bulker, and today—expensive! What’s more, when it came to the smaller parts of the vehicle like the suspension system, inventors were still in the earlier stages of discovering what makes up a smoother ride—and in essence, still are today!

The Challenge of Finding Replacement Parts

Whether you want to refer to these earlier cars as old or classic, the truth somewhat remains that indeed, they don’t make them like they used to! So for car collectors and classic car owners who may have received their treasure through an inheritance, an auction, or the sheer luck of stumbling upon it in a junkyard, chances are you’re probably having a challenge finding replacement parts for your leaf spring.

The chances are quite slim that you’ll find leaf springs for a classic car at your local automotive store. Even if you’ve gotten by with combing junkyards for parts, when it comes to classic cars, you won’t have much luck. Even if you contacted the manufacturer, the response that you’ll most likely get is that particular model is obsolete and yes, they don’t make them anymore!

So if the manufacturer doesn’t make leaf springs for their earlier models, and finding replacement parts makes finding a needle in a haystack look easy, what exactly are your options? You could, like most ex-classic car owners, scrap the parts out and sell the material, or you can call New truck Spring, a leaf spring replacement and manufacturing company in New Century, KS.
