Strut Suspensions
→Kinematics corresponds to double-wishbone suspension, where upper wishbone is of infinite length or replaced by a sliding guide.
Sliding guide→The telescopic shock absorber whose casing is firmly fixed to the wheel carrier and whose shock-absorber rod is also used for wheel guidance.
Advantages: → Reduced design expenditure and space requirements at the wheel axles.
→Specially useful in FWD automobiles with transversally mounted engine-transmission units.
Diadvantages: →Less room for design of the kinematics of wheel guidance compared to double-wishbone suspensions.
In the strut suspension concept according to the McPherson principle (Earl McPherson, 1945), the lower transverse arm is made up of a wishbone and a stabilizer, see figure.
