SHOCK, I always wanted to know WHY THEY SERVE? Its functions are:
- Keep tires contact the pavement
- Dar
cornering stability - Increased comfort
vehicle
In performing these functions, also help:
- Reduce braking distances
- Avoid skids in surfaces with jumps
- Avoid "lancheo" in fords
- Helping a uniform wear on tires
HOW IT WORKS: Actually a damper is a hydraulic piston with limited flow.
The purpose of a buffer is to prevent the tire bounce harmonic motion generated by the spring or torsion bar. To accomplish this
using 2 cameras (deposits) of oil and travels from one to the other when activated the shock.
There is a valve that regulates the flow of oil between the chambers, "holding back" the advance of the shock, thus avoiding the annoying wobble of the rim.
WHAT ARE THE SHOCK "GAS"? : Shocks "gas" are not really "gas" are hydraulic and they also come loaded with pressurized nitrogen gas, this means that instead of air trapped in the chambers when the oil leaves is nitrogen gas.
The gas provides advantages are:
- Prevents bubbles: Bubbles are formed when the shock works intensely and seriously diminish the functions of the shock.
- Increases the rate of return: Decrease the time needed after a jump to the tire contacts the pavement.
These advantages result in greater control over the steering and braking of the vehicle.
The only disadvantage of gas-pressurized shock absorbers is that they are more "rigid", the suspension of your vehicle becomes more "hard."
These dampers are recommended for vehicles that are used intensively or frequently out of freeway.
TYPES OF SHOCK
For the construction of the suspension:
The "normal" usually referred to simply as "shock absorbers": is the classic design of the shock, is characterized by mounting (the way it is attached to the vehicle) is performed using 2 to 4 screws, not a structural component of the suspension (vehicle could flow without shock!, do not try ...) and is the cheapest type of cushion there.
Those who use the system Mac.Pherson usually simply called "struts" cushion These structural part of the suspension of the vehicle, usually used for front-drive cars from 1978 onwards (although there are many exceptions and Variety in designs suspension), this form of
suspension design is economical and efficient in terms of static and dynamic geometry of the suspension, but the very high performance cars (and price!) use more complex and better mechanisms to achieve a geometry more perfect in the suspension.
This type of damper is attached on top of a turntable and at the bottom to the "hub" (the hardware that holds the wheel and brakes). There are some more complex than the buffer contains parts of the suspension.
gas springs: For applications on trunk, hood, 3 rd and 5 th door, are the equivalent of a spring but loaded with gas, help the safe and easy removal of the parts shown.
SHOCKS SOME SPECIAL FEATURES: damper rates mentioned below can be purchased usually hydraulic or pressurized gas with consequent additional differences: Reinforced
: generally are those that use a valve closer (making them slightly stiffer), and are designed for use in large cars, pickup trucks, some manufacturers also use larger diameter pistons designed to withstand more.
With air bag overload: This shock it is ideal for trucks and / or trailer. Designed to keep the vehicle height can be inflated or deflated as needed. The units can accept an extra charge of 340 to 430 kg (Although the carrying capacity of the vehicle may be limited by the vehicle suspension, tires and transmission, see the manual for your vehicle owner for more information.) In these there is the option of installing an engine compartment in order to change the height level without declining to the vehicle. Are installed only on the rear axle of the vehicle.
With spring reinforcement: It works in much the same as above, except that the spring is not adjustable and not worry about "deflation" or "inflate" the shock.
of adjustable stiffness: usually are made for sports cars and vans are useful for off-road applications where you want a very hard shock for competitions or sporty handling and a smoother for everyday use. In these there is the option of installing an engine compartment in order to change the level of stiffness without the need to get off.
Some high performance cars also include a buffer such as original equipment for a sporty handling without sacrificing comfort.
with piston grooving: Monroe patented product (sensatrac) in which the shock is softer in short run (small imperfection in the road) and more rigid in long run (fords deep or cornering). It is a soft cushion as it was originally designed for the American Union where most of the highways are very smooth and no curves.
steering stabilizer damper
: are used to reduce vibration in the direction, are generally used in 4x4 trucks, although some vehicles like the VW sedan also wear it.
For competition applications, or heavy use outside way, some manufacturers sell a kit consisting of 2 steering stabilizer shocks, Dust Cover and bases for installation.
In conclusion, for each vehicle is a shock that was the one who decided their designers. Replace it, improve somewhat at the expense of anything worse. Use original spare parts. The lifesaving shock!
