SISTEM SUSPENSI

VIBRATIONS and quality of driving

In the subject of vibration and quality of driving a car, there

are terms:

Sprung weight: Weight ditumpu car by the spring suspension

Unsprung weight: Weight axle and parts - Other parts are

located

Between the wheels - wheels and springs

Note:

Sprung weight the greater the better quality of driving

GETARAN GETARAN PADA AUTOMOBIL

~ Pitching: Vibration resulting front and rear end of car

moving around the center of gravity of the vehicle (car)

~ Rolling: swinging movement laterally

~ Bounching: Movement up and down

SPRING ( PEGAS )

LEAF SPRINGFunction

To connect the frame to the axle and also

to cushion the shock absorber caused by

road surface

Spring constant

Nature of the materials change shape when

a load, and back into shape when the load

is released. The event is called the

elasticity

The amount of deflection is proportional to

the force exerted.

Comparison between the force exerted by

the deflection is called "spring constant"


6/27

COIL SPRING

Long steel rod rolled.Compared with leaf springs, coil spring is longer so as

to have a better resistance to shock, there is no friction

when there deflexi, so as to provide better comfort.

Coil spring does not have the shock absorbing

properties, is sufficient and can not guarantee its axis.

Spring constant

If the forces acting = W

The amount of deflection = A

High free = L

So spring constant = W / A


7/27

HELPER SPRING

Helper spring is paired with an additional spring above the main spring on the truck

in heavy transport vehicles.Helper spring working together - together with the main spring, when the vehicle got

a load on the number of specifications


8/27

HOLLOW SPRING

Spring Hollow is a hollow piece of

rubber in the middle and bolted to

the top of the axle, control arm or

in part, located above the frame.

When the hole closed and the air

trapped in the hole serves as a

springSpring Hollow is generally used

as an additional spring to protect

the frame from the impact of the

spring


9/27

AIR SUSPENSION

Containing air bellows attached to the place where the leaf springs are usually

placed screw or spring, to ensure heavy vehicles. Action produced by the elasticity

of the absorption of air compression within the bellows and additional air space.

Violence springs are subject to change - change in accordance with the load

SUSPENSI MODEL RIGID DENGAN PEGAS DAUN

In the rigid model of the wheel suspension - wheels mounted on one axis and attached

to the body through the spring

Advantages:

~ Construction of simple and powerful

~ Changes tread or chamber caused by a small axle movementDisadvantages:

~ Quality tabilitas wheel drive and less

~ Tendency occurs horizontal movement

SUSPENSI MODEL INDEPENDENT

In the model of independent suspension, left and right wheels are not attached to a

single axis, but on each - each axle, so that the work alone - alone in absorbing the

shock. Called "knee action"Advantages:

Better ride qualityTangent ability is a better way (rod holding)Disadvantages:

Construction complex

onstruction:Upper Arm, Lower Arm, Knuckle form a rectangle with a coil spring and shock

TORSION SPRING

Stabilizer

Torsion spring

Lower control arm

Upper control arm

When a steel rod, tied one end firmly on the rod is at rest, the other end tied to the arm, butwhen the arm moves down and up, then this steel rod of movement will tend to resist this.

Thus arose the absorption effects such as a spring leaf (leaf spring) or a screw spring (coil

spring)


16/27

MACHPERSON SUSPENSION

Suspension machperson model has no upper arm,

so the simple construction and does not need

tuning "FRONT WHEEL alignment" unless "TOE


17/27

SHOCK ABSORBER

The function of the spring is to prevent collisions received by the wheels of thevehicle body be forwarded to

But without a vehicle shock absorbers to be a bad way.

Shock absorber serves to absorb excess elasticity of the spring which tends to

swing - swing.


18/27

PRINSIP KERJA SHOCK ABSORBER

Single action Double action

direct-acting type

In the shock absorbers to shrink, the piston inside the cylinder slides and encourage

existing oil under the piston, the oil will move upwards through the orifice, with the

prisoners on the elasticity of the spring orifice restrained. And vice versa.

JENIS DUCARBON

This type of shock absorber contains high pressure

gas which has properties very stable silencer.

Benefits of ducarbon

Good heat radiation due to a single tube

Hydraulic shock does not occur when there ischange in motion

No hissing sound occurs when the oil flows

via a valve (orifice)

STABILIZER

Function:

To prevent vehicles flying at the time of inflection.


22/27

STRUT BAR

Function:

To support the lower arm so as not to move forward and

backward at the time the vehicle running
