the modern car ride comfort, so that consumers tend to buy car comfort
as an important measure. In fact, in addition to car ride comfort
softness of the seat, the support force and other factors, the most
relevant is the car's suspension system which is connected between the
frame and the axle force transmission parts, such as traveling to other
properties security, through sex, stability and adhesion properties have
a significant impact.
Basic structure of the suspension system
Simply put, automotive suspension including elastic components, shock
absorbers and power transmission devices, three parts, namely, a buffer,
damping and force transmission effect.
From cars in terms of the
elastic element multi-finger coil springs, only withstand the vertical
loads, uneven road surfaces and inhibition of easing the impact of the
body, with a footprint no lubrication filial filial quality advantages,
but because there is no friction and no damping itself effect. Hydraulic
Shock Absorber shock absorber also refers, its function is to
accelerate the attenuation of the vibration of the body, it is also the
suspension system is the most sophisticated and complex piece of
machinery. Power transmission device refers to the upper and lower arm,
etc. fork frame steel frame, steering knuckles and other components used
to transmit longitudinal forces, lateral forces and moments, and to
ensure that the wheels relative to the frame to determine the relative
motion of a law.
In practice, as long as the same with the possible role of the three.
Cars with independent suspension into a trend
Suspension system
car diagnostic tool two classifications:
(L) Non-independent Suspension: non-independent suspension mounted on a
wheel axle ends of the whole, so that when the wheels running while
beating, it will also affect the other side of the wheel to make
corresponding beating, so that the whole body vibration or tilt. Take
this car suspension system generally poor stability and comfort, but
because of its simple structure, large capacity, the suspension used for
trucks, buses and some other common special vehicles.
(2) independent suspension: independent suspension axle

is divided into two sections, each wheel independently with coil spring
mounted on the frame below, so that when the wheel while beating
occurred, the other side of the wheel is not directly affected,
significantly reducing body vibration , automotive comfort also able to
greatly improved, especially in the high-speed roads, it can also
improve the car's driving stability. However, this suspension structure
is relatively complex, a small capacity, but also related to the car
drive system, steering system becomes complicated. Most cars have front
and rear suspension independent suspension uses a form, and has become a
trend.
Independent suspension structure divided candle, McPherson,
link type etc., which are similar in shape candle and McPherson, both
the coil spring and shock absorber together, but the structure there are
significant differences different. Candle using the pin moves along the
main wheel suspension form, shaped like a candle is named, is
characterized by kingpin position and wheel alignment angle is not
jumping up and down with the wheels of change, is conducive to vehicle
handling and stability. McPherson strut type is twisted with the lower
wishbone suspension consisting of forms of shock absorbers can cater
steering kingpin, steering knuckle can rotate around it, is
characterized by kingpin position and wheel alignment angle with the
wheels jumping up and down and change, with candle suspension just the
opposite. The suspension structure is simple, compact arrangement, small
changes in wheel alignment, with good driving stability. So, now the
most used cars independent suspension is MacPherson suspension.
