Automobile shock absorbers are a very simple but important purpose - they prevent the loss of wheel contact with the road surface and eliminate resonance. The better adhesion, the more precise handling. In general, then, is a truism. Adhesion is determined primarily by two factors - the stiffness of springs and shock absorbers. By the shock absorbers, however, to apply the word "rigidity" is not quite correct. Their characteristics are determined by performance of valves and chokes, bypass oil, the quality of the oil itself, and of course design features in each case. Surely every motorist holding a strut tower or cartridge, slide and pull rod. Many people probably noticed that the effort of compression and rebound are very different. Manufacturers of shock absorbers adjust past in accordance with the design of suspensions for each individual vehicle. For example, if the suspension spring, it is now used two-pipe hydraulic design, torsion - Single-pipe with high pressure gas (option). It is known that the automaker is using the experience and the work of other firms to create the final product - the car under its own brand. It's no secret that Japanese automakers are using shock absorbers are basically of two firms - Kayaba and Tokico. On the sports version put more progressive Bilstein, electrician used by Mitsubishi or Hitachi and so on. On models of the European assembly, you can see the lights Hella, injectors Bosch. In general, the "capitalist" integration in action. In Russia alone, the production cycle previously carried out completely - machine made from a piece of iron. Now the situation has slightly changed, but the quality is somehow stagnated. Without detracting from the shock absorber themes, we see that consumer characteristics of the car is the ultimate design and characteristics of the suspension. Dampers here play an important role. It is clear that no one will enter into a contract with the company for the development of Koni suspension components for the Chevrolet Aveo, for example - is too expensive, but for the Subaru Impreza WRX STi - easily. The developers of each model of car trying to create the best option for price / quality ratio. But not everyone turns out. "Podvesochniki" constantly struggling with the decision of the most important problem - handling / comfort. Unfortunately, these concepts are diametrically opposed, as well as methods for their solution. Therefore, begin to appear custom designs - pneumatic rack with variable stiffness and variable ground clearance. It is known that it is quite expensive and not always justified, and the failure of even one such stand would cause serious financial harm to the owner of this car. Most motorists are not particularly fond of pinpoint handling. Drove to work or testimony - and right. When buying a used car performance shock absorber struts are usually tested in three ways: 1) visual inspection - is there any oil leaks, and 2) there is a knock on the rack while driving irregularities, 3) attempt to swing in a vertical plane of the body. If the car does not have more than one vibration state of shock absorbers is recognized as satisfactory. In fact, of course, not everything is so primitive, stand, even at 50% wear completely extinguish oscillations of the present machine, but can not cope with the problem at the speed of rotation, etc. However, in all honesty, who the owners of used cars, rides on a fully serviceable sling? There are even anecdotal cases. For example, the owner of one old foreign cars complained of a strange incident that happens with the car every time on the street temperature varied from plus to minus (it was winter). Worth it to hit a frost, as the car gets tough, like a rally car and jumpy, like a ball. Revealed the following - shock absorber stand him since time immemorial were completely empty, and the anthers and glands due to a solid path has long been absent. At zero temperature in the rack were recruited water, which, in principle, did not interfere with driving. At the "minus", this water turns to ice, and became a solid stand - rozen-in stock did not give a compression spring. A few days later under the weight of stock car broke the ice, ride became more comfortable. Then again, the "plus", then "minus", and everything is repeated. The driver moved only in the city in the style of the first, second, stand, so no shock absorbers on the car and the deterioration of the controllability is simply not noticed. Somewhere on the road at a car "ubitsya" It would be extremely easy, as the absence of damping effect, it is most of the time spent would be in the air, rather than on asphalt. Imagine a "teapot" which turns the steering wheel and the car continued going straight ahead, as the wheels do not touch the ground. But he needs something right! Frightened by the driver turns the steering wheel at a larger angle, then restore the wheel contact with the asphalt and shock absorbers provide a single, but very important purpose - to maintain a constant connection to the road wheels. They do not give a swing machine on the gentle waves, helping to keep control on the "washboard" and most importantly - is quenched in the bud resonant phenomena. The car, like any physical body has its own frequency of vibration, so the coincidence of adverse conditions the body simply enter the resonance. Then - and so clearly. Prevents such troubles phenomenon is only one element of the design - a shock absorber. Vibration when braking, but these elements, too, pay nothing, so the braking distance in the "dead" rack increases significantly. In general, in a modern car there are many different parts, which in the end, "the speed is not affected." Shock absorbers, unfortunately, is one of them. The brakes, by the way, too. Broken tie rod and ends, knocking ball joints, steering kardan with a huge backlash, "hernia" on wheels - the list goes on. Dampers immediately occupy a separate position - the car at some point simply ceases to obey the driver, although just a moment ago, there were no signs of trouble. Therefore I'd like to give a little advice to all motorists - it is better to pay money for diagnosis and repair of suspension than for washing / polishing body and Dry cleaning. It is my firm opinion. Ride on a clean machine definitely nicer, but I think the priorities need to set correctly. Ideal option, of course - new, clean car with low mileage, which are serviced from an authorized dealer. Monthly income in excess of cost of living at least 100 times, too, is a welcome phenomenon. Unfortunately, not all citizens of Russia, this is available, but all I want to live, despite the low level of material prosperity. Therefore, the technical condition of machines needed to pay full attention. At the end of this article will try to elaborate on the designs and varieties of shock absorbers, and also try to give advice on how to optimize the cost of replacement struts, if the time has come. To be completed.
