Advantages of front independent suspension system

Automotive industries use a large variety of suspension systems to sustain car weight. They develop unique characteristics and advantages in the sense of operating camber and caster angle, engine accommodation space sprung weight, etc. Among several suspension solid axle and independent axle systems used at a large scale. We already discussed the suspension system's function and principle and the classification suspension system depicted below figure.

Types of the suspension system

The reasons behind the development of an independent suspension system are several disadvantages of the rigid beam axle suspension system as mentioned below:

• As wheels' mounting is at the end of the rigid beam so, any movement in one wheel is directly the same as another end wheel. It leads to camber and caster angle act simultaneously on both sides, resulting in inaccurate steering geometry.
• Lower roll stiffness leads to producing the over-steering effect.
• Minimum wheel adhesion due to high un-sprung weight.
• Maximum spring deflection is the lower result in hard springing.
• Lower space for engine accommodation.

In contrast, the advantages of the independent suspension system are wheel movement and independence of each other. So, leads to several advantages over rigid beam axle suspension systems. And are;

• Lower Un-sprung mass.
• Softer suspensions just due to the low spring rate that enables large deflection of wheels.
• Front springs are located at enough that promotes understeer condition.
• Double wishbone provides good castor angle variation independently that overcomes the effect of steering geometry.
• And last it provides large space for engine accommodation.
