What type of suspension incorporates the shock absorber and coil spring in one assembly?

The MacPherson strut is a suspension design that combines the shock absorber and coil spring into a single integrated unit. This design is commonly used in many modern vehicles because it simplifies the construction and reduces the overall weight of the suspension system. The MacPherson strut offers several advantages, including space efficiency, as it requires less room compared to other suspension systems, and it allows for easier manufacturing and installation.

In this setup, the coil spring is mounted directly around the shock absorber, which helps to provide a compact and effective suspension layout. This arrangement not only supports the vehicle's weight but also absorbs road shocks, contributing to a smoother ride. The simplicity and efficiency of the MacPherson strut have made it one of the most popular suspension designs in the automotive industry.
