Double Wishbone Suspension

[ISO2015]

Hi Friends

Is double wishbone suspension is really better (comfortable) than MacPherson Strut?

Tata Safari/Scorpio is having double wishbone but Safari is more comfortable than scorpio why is that?

XUV 500 is having MacPherson strut. How does it compares with Safari suspension?

Is it true that Double wishbone is more rugged and retains wheel alignment over longer time?

Double wishbone simply refers to the way the wheels are connected to the car. Comfort of suspension comes from how the wheels are sprung and damped. Only point- in a double wishbone setup, the wheels remain upright even when the body moves i.e. camber doesnt change which keeps more of the tyre in road contact & tyre wear even

Thanks Ameyan

Any more inputs friends?

I think JLR also uses double wishbone tech.

Below is the info for the reference from net:
ouble wishbone suspension provides the engineer more free parameters than some other types do. It is fairly easy to work out the effect of moving each joint, so the kinematics of the suspension can be tuned easily and wheel motion can be optimized. It is also easy to work out the loads that different parts will be subjected to which allows more optimised lightweight parts to be designed. They also provide increasing negative camber gain all the way to full jounce travel, unlike the MacPherson strut, which provides negative camber gain only at the beginning of jounce travel and then reverses into positive camber gain at high jounce amounts.

Conversely, it may take more space and is slightly more complex than other systems like a MacPherson strut. Due to the increased number of components within the suspension set up it takes much longer to service and is heavier than an equivalent MacPherson design. At the other end of the scale, it offers less design choice than the more costly and complex multi-link suspension system.
