Shock Absorbers
Passengers from the modern period is lucky since they do not have
to worry of rolling cars because of rocks and other hindrances that can
cause the driver to loose control of the vehicle. From the desire to
have better vehicle control, car suspensions were used to provide
smoother pivots. Together with suspensions are shock absorbers to damp
the up and down oscillation of the car's leaf springs. Early shock
absorbers lack durability and efficiency but as new technology arise;
various improvements were done to aid the driver in various road
conditions.
How do shock absorbers work? First and foremost,
the basic purpose of shock absorbers is to manage the movement of the
spring and suspension done by converting the kinetic energy produced by
the suspension to thermal or heat energy degenerated by means of
hydraulic fluid. Shock absorbers work like an oil pump. On the end of
the piston rod is a piston that works with the hydraulic fluid on the
car's pressure tube. The up and down movement of the suspension forces
the hydraulic fluid to the tiny holes inside the piston but since the
holes are just small enough, the piston slows down and thus also
decreases the movement of the suspension and spring.
The
resistance produced by the shock absorber is dependent on the quantity
and size of the holes or orifices in the piston and the speed of the
suspension movement. Technologically advanced shock absorbers are
equipped with velocity hydraulic damping devices which provide
increased speed in the movement of the suspension to attain greater
resistance. The outcome is a versatile shock absorber that can easily
jive with various types of roads. Bounce, sway, brake dive and
acceleration squat are then reduced.
Common designs of shock
absorbers used nowadays are twin tube designs and mono tube designs. A
twin tube shock absorber is made up of an inner and outer tube that
work together to achieve the intended purpose. A mono tube on the other
hand, as the name implies, is made up of one tube mounted in an upside
down position to decrease weight.
