Basic Principles of Automotive suspension system constitutes

Increasingly focused on LAUNCH X431 iDiag 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 LAUNCH X431 iDiag 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.
