It consists of an enclosed cylinder that bolts to the top of the hub; within it is the shock absorber or damper. At the top it has a wide collar that cups the coil spring, while the damper shaft runs all the way through the centre of the coil to the top of the spring unit, which is bolted fast to the structure of the car.
In this way the MacPherson strut creates a three-point fixing structure for the wheel that proves very strong and versatile, and can easily be tailored to more demanding usage like track driving. Some cars also now use a wishbone instead of the old control arm and radius rod combination. A double-wishbone setup allows more adjustment for camber and roll centre, which can reduce body roll.
The fact remains that the MacPherson strut is a brilliantly effective way to combine strength, spring and stability at a low manufacturing cost.

The example cited in the Oper requires that the link for the stabilizer bar be required to have rotational capability so as not to bind the steering of the vehicle.
Further, In the Opel example as the steering is changed during a cornering manuever, as the attachment of the rod to the strut is not on the steering axis, the roll stiffness of the vehicle will change. Hello David, Your feedback on this article is very interesting and give us more details concerning this type of suspension which has been used for decades and has seen lot of improvements.
Hello, i want to know, what is the best, pseudo macpherson independient, or macpherson, and for a rural way?? The independant version of this suspension is mostly used on sport cars and is more expensive. The MacPherson strut is used on several upscale cars.
Question: Are there any inherent limitations imposed by this type suspension on upward wheel movement? Hi Marvin, Thanks for your comment on this post. The MacPherson strut is not very used on new cars but the pseudo MacPherson is used a lot.
So, regarding the MacPherson, it has strong limitations on camber gain on upward wheel movements. For both suspension, vertical dimension is a limitation in term of space in the wheelhouse. I hope this answer to your question. You need to draw the crossing point between the line passing through the triangle and the perpendicular of the strut.
Then you draw a line from this point through your contact patch. You do the same thing on the other side and for your rolling center. You cross the two lines drawn and then you get it! I can send you a drawing if its not clear! The problem is that you need to update it at each iteration as your strut is moving in roll. Dear Sir, This is very knowledgeable article regarding suspension. I have one doubt is that , does by using this suspension system can we lift it around 60 degree with wheel.
This requirement is i need for defence weapon system. Can you help me to achieve this suspension system. This, as they call it, is a second generation Celerio. I found out recently that the unit does not have a stabilizer bar or anti-roll bar. Could it be that Suzuki has used that Pseudo-Macpherson type of suspension that it has eliminated stabilizer bar as a standard front suspension component?
