What does MacPherson independent suspension mean?
2 Answers
The suspension system refers to a connecting structural system between the body, frame, and wheels. The MacPherson independent suspension is one type of suspension system, mainly consisting of components such as shock absorbers, suspension springs, lower control arms, longitudinal rods, steering knuckle arms, rubber bushings, and connecting rods. The primary structure of the MacPherson independent suspension is formed by a coil spring mounted over the shock absorber. The shock absorber prevents the coil spring from shifting forward, backward, left, or right when under force, restricting the spring to only vertical vibrations. Additionally, the length and tightness of the shock absorber's stroke can be adjusted to set the suspension's stiffness and performance.
As an ordinary driver with over a decade of experience in family sedans, MacPherson strut suspensions are widely used in my cars—they're a common type of independent suspension system. Simply put, it integrates the spring and shock absorber into a single unit mounted above the wheel, allowing each wheel to move up and down independently. This design saves space and is cost-effective, offering agile handling for city driving with quick responses over speed bumps. However, it struggles with large potholes or high-speed cornering, where body roll becomes more noticeable. The upside is easy maintenance; during my own checks, I mainly look for oil leaks in the shock absorbers and ensure regular tire balancing. Commonly found in the front wheels of most compact cars and SUVs, this suspension helps reduce vehicle costs while remaining practical for daily commuting.
