The MacPherson strut suspension system offers excellent responsiveness and handling, is simple in structure, occupies minimal space, is low-cost, lightweight, and suitable for accommodating large engines and fitting into small vehicle bodies.
Other Advantages
Additionally, other advantages of the MacPherson strut suspension include:
a. Due to a larger effective distance C, the forces acting on body connection points E and D are smaller;
b. There is only a small distance D between points G and N;
c. Large spring travel;
d. Three support points are eliminated;
and
Facilitates the construction of the front floor pan shape.
Disadvantages
However, the MacPherson strut suspension system has some disadvantages, such as:
When driving on uneven roads, the wheels tend to self-steer, requiring the driver to exert effort to maintain the steering wheel's direction. The strut is prone to bending under severe impact, which can affect steering performance. Furthermore, stability is poor, and its resistance to body roll and brake dive is weak. While adding a stabilizer bar can alleviate these issues, it cannot fundamentally resolve them. Additionally, durability is not high, shock absorbers are prone to oil leaks, and require regular replacement.
