MacPherson Strut Suspension Explained: Pros and Cons

The MacPherson strut suspension system is a highly effective type of independent suspension that is widely used in automobiles. In fact, it was invented by Earl S. MacPherson in the 1940s and has become a popular choice due to its simple yet efficient design. This system integrates a shock absorber, coil spring, and steering knuckle into a single assembly, making it a reliable and durable option for any vehicle.

The basic components of a MacPherson strut suspension system include:

1. Strut Assembly:

   The main component of the system is the strut itself, which acts as both the structural and damping element. It's a vertically oriented tube that houses the shock absorber and provides a structural link between the wheel and the body of the vehicle.

2. Coil Spring:

   A coil spring is situated around the shock absorber within the strut assembly. It supports the vehicle's weight and provides the necessary suspension compliance to absorb road shocks and bumps.

3. Steering Knuckle: The bottom end of the strut assembly is connected to a steering knuckle, which holds the wheel hub and allows for steering movement.

4. Mounts and Bearings:

   The top end of the strut is mounted to the vehicle body using rubber mounts and bearings. These allow the strut to pivot and absorb vertical movement while minimizing the transmission of vibrations to the vehicle body.

The MacPherson strut system boasts several advantages over other suspension systems. Its simple design reduces manufacturing costs and makes maintenance a breeze. Plus, its compact size frees up valuable space in the engine bay for other components. This cost-effective system also provides a comfortable ride by effectively absorbing bumps and road irregularities with its coil spring and shock absorber. Furthermore, its design flexibility allows it to be adapted for use in a variety of vehicle types, from compact cars to SUVs, by adjusting the components' sizes and tuning the suspension characteristics.

MacPherson strut systems have some limitations that should be taken into account when considering them for your vehicle. Firstly, these systems offer limited adjustability compared to more complex suspension systems, which can limit the fine-tuning of handling characteristics. Additionally, in high-performance applications, more advanced suspension systems (like double wishbone) can provide better control over wheel movement and handling precision. There is also a tendency for camber changes during cornering, which can affect tire contact and handling. Moreover, the integrated design of the strut assembly can transmit some road vibrations and impacts to the steering system, potentially affecting the steering feel. Lastly, the compact design can limit the size of brake components and hinder the installation of large-diameter wheels. Therefore, it is important to carefully consider the advantages and limitations of MacPherson strut systems before making a decision on whether or not to install them in your vehicle.

The MacPherson strut suspension system is a popular choice for many vehicles due to its simplicity, affordability, and decent ride comfort. However, it does have its limitations in terms of adjustability and high-performance handling. As a result, more sophisticated suspension systems have been developed for specialized applications.
