Proride Absorbers

What is Shock Absorber?

Other names for a shock absorber include damper and dashpot. The automotive suspension component is often called just shock. During the early 20th century in the U.S., the then-well-knownHoudaille brand (pronounced WHO-dye) was in some places a genericized trademark for the device,^[but has since disappeared from use.

Pneumatic and hydraulic shock absorbers include cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston. 

The shock absorber absorbs and dissipates energy. One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most dashpots, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of dashpots, such as electromagnetictypes, the dissipated energy can be stored and used later. In general terms, shock absorbers help cushion vehicles on uneven roads.

Application

Shock absorbers are an important part of automobile and motorcycle suspensions, aircraft landing gear, and the supports for many industrial machines. Large shock absorbers have also been used instructural engineering to reduce the susceptibility of structures to earthquake damage and resonance. A transverse mounted shock absorber, called a yaw damper, helps keep railcars from swaying excessively from side to side and are important in passenger railroads, commuter rail and rapid transitsystems because they prevent railcars from damaging station platforms. The success of passive damping technologies in suppressing vibration is demonstrated by its market size—around US $4.5 billion.

In a vehicle, shock absorbers reduce the effect of traveling over rough ground, leading to improvedride quality and increase in comfort. While shock absorbers serve the purpose of limiting excessive suspension movement, their intended sole purpose is to dampen spring oscillations. Shock absorbers use valving of oil and gasses to absorb excess energy from the springs. Spring rates are chosen by the manufacturer based on the weight of the vehicle, loaded and unloaded. Some people use shocks to modify spring rates but this is not the correct use. Along with hysteresis in the tire itself, they dampen the energy stored in the motion of the unsprung weight up and down. Effective wheel bounce damping may require tuning shocks to an optimal resistance.

Spring-based shock absorbers commonly use coil springs or leaf springs, though torsion bars are used in torsional shocks as well. Ideal springs alone, however, are not shock absorbers, as springs only store and do not dissipate or absorb energy. Vehicles typically employ both hydraulic shock absorbers and springs or torsion bars. In this combination, "shock absorber" refers specifically to the hydraulic piston that absorbs and dissipates vibration.

dgn kata lain....
KETIKA memandu, pernahkah anda mengalami kereta melantun terlalu kuat apabila termasuk ke dalam lubang atau bonggol jalan? Kereta akan terasa melantun-lantun lebih daripada sekali sebelum kembali ke posisi asal.

Ada ketikanya kereta terasa membuai-buai dan sukar dikawal pada kelajuan tinggi di lebuh raya. Pemandu akan sering membetulkan posisi stereng ketika sedang mengambil selekoh.

Situasi ini...
ada kaitan dengan Shock Absorber atau Penyerap Hentak kereta anda. Apa yang pasti ia adalah adalah salah satu komponen terpenting kenderaan yang membabitkan keselamatan dan keselesaan memandu.

Shock Absorber yang rosak boleh menyebabkan kerosakan lain pada kenderaan dan di dalam kes yang lebih serius, mampu menyebabkan kemalangan. Pada kelajuan tinggi, kereta akan terasa bergerak tidak lurus dan anda terpaksa membetulkan kedudukan stereng terlalu kerap (over-correct). Kereta juga akan terasa seperti "terapung" di atas lebuh raya. Ini bermakna Shock Absorber telah rosak dan perlu diganti dengan segera.
