Shock Absorbers

In most mechanical mechanism, a shock absorber is also called a damper, which is mechanical or hydraulic equipment which is designed to absorb and damp the shock impulses. This device does this by converting the kinetic energy of the shock into another form of energy, which is then dissipated through natural process. Regarding the shape design, most shock absorbers are a form of dashpot, and that is a damper which resists motion through viscous friction. 

Shock absorbers are widely used in the automotive industry as well as motorcycle sectors to help drivers and riders handle the vehicle with better stability by forming a sensitive suspension system, which serve the purpose of limiting excessive suspension movement. Shock absorbers’ targeted purpose is to damp spring oscillations, and shock absorbers use valving of oil and gasses to absorb excess energy from the springs. Speaking of the spring, the spring rates are determined by the manufacturer based on the weight of the vehicle, loaded and unloaded.

Spring based shock absorbers

There are different kinds of shock absorbers, and one of the commonly used type is the spring-based shock absorbers which are constructed by using coil springs or leaf springs, though torsion bars are used in torsional shocks as well. Although ideal springs alone, are not shock absorbers. In fact, because springs only store and do not dissipate or absorb energy effects, this is the reason why.
 
In the automotive industry, vehicles typically employ both hydraulic shock absorbers and springs or torsion bars. In this combination, the term shock absorber refers specifically to the hydraulic piston that absorbs and dissipates vibration. currently, composite suspension system are utilized mainly in 2 wheelers and also leaf spring are made up of composite material in 4 wheelers.

 

The development of shock absorbers

Generally speaking, in common with carriages and railway locomotives, most early motor vehicles adopted leaf springs as the primary tools. One of the critical characteristics of these springs was that the friction between the leaves offered a degree of damping, and in a review of vehicle suspension issued around the 1910s, the lack of this characteristic in helical springs was the reason it was impossible to use them as the main spring units. Meanwhile, the amount of damping provided by leaf spring friction was limited and variable according to the conditions of the springs, no matter whether wet or dry, and it also operated in both directions. Motorcycle front suspension adopted coil sprung Druid forks from about the year of 1906, and similar designs later added rotary friction dampers, which damped both ways - but they were adjustable by people. These friction disk shock absorbers were also fitted to many cars.

 

Other types of vehicle shock absorbers

Among the constructions of shock absorbers for the vehicle usages, there are mainly two kinds of classifications, one is mono tube and the other is twin tube composition. The mono tube appeared in the era of 1950s and it is a gas-pressurized shock and also comes in a coil-over form, consists of only one tube, and the pressure tube. Although it has two pistons as the basic frame, it is a mono tube. These pistons are called the working piston and the dividing piston, and they move in relative synchrony inside the pressure tube in response to changes in road smoothness. As a matter of fact, the two pistons also completely separate the shock's fluid and the gas components. The mono tube shock absorber is consistently a much longer overall design than the twin tubes, granting it difficult to mount in passenger cars designed for twin-tube shocks. Such design has its own advantages.
 
On the other hand, two tube, which is also called twin tube, which is consists of two nested cylindrical tubes, an inner tube, or the pressure tube, and an outer tube called the reserve tube. At the bottom of the device on the inside, there is a compression valve or base valve. When the piston is forced up or down by bumps in the road, hydraulic fluid moves between different chambers through small holes or orifices in the piston and through the valve, converting the shock energy into heat, and that must then be dissipated as we have introduced in the previous paragraphs due to the physical laws.

 

Installation

The installation of the shock absorbers must be done by professional technicians who will first do a series of technical estimations of the loading, materials, anticipated road conditions, and many other critical issues into account. After the comprehensive calculations of the variables, the installation of the shock absorbers also takes serious professional knowledge in order to make the best usages of the inner parts of the shock absorbers and grant the maximum safety of the users of the vehicle. Among most mechanical mechanisms, a shock absorber is mechanical or hydraulic equipment which is made to absorb and damp the shock impulses. This equipment does this by converting the kinetic energy of the shock into another form of energy, which is then dissipated through natural process. Regarding the shape design, most shock absorbers are a form of dashpot, and that is a damper which resists motion through viscous friction.
