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 SPRING Function 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"

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

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

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 spring Spring Hollow is generally used as an additional spring to protect the frame from the impact of the spring

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

JENIS – JENIS SUSPENSI 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 movement Disadvantages: ~ Quality tabilitas wheel drive and less ~ Tendency occurs horizontal movement

SUSPENSI MODEL RIGID DENGAN PEGAS ULIR

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 quality Tangent ability is a better way (rod holding) Disadvantages: Construction complex

MACAM – MACAM SUSPENSI INDEPENDENT

MODEL WISHBONE DENGAN PEGAS COIL onstruction: Upper Arm, Lower Arm, Knuckle form a rectangle with a coil spring and shock

TORSION SPRING Stabilizer Torsion spring Upper control arm Lower control arm When a steel rod, tied one end firmly on the rod is at rest, the other end tied to the arm, but when 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)

MACHPERSON SUSPENSION Suspension machperson model has no upper arm, so the simple construction and does not need tuning "FRONT WHEEL alignment" unless "TOE “

SHOCK ABSORBER The function of the spring is to prevent collisions received by the wheels of the vehicle 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.

PRINSIP KERJA SHOCK ABSORBER Single action Double action Orifice Orifice Piston Piston 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.

CARA KERJA SHOCK ABSORBER

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 is change 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.

STRUT BAR Function: To support the lower arm so as not to move forward and backward at the time the vehicle running
