What type of independent suspension combines spring, shock absorber, and control arm into one compact unit?

The strut-type suspension integrates the spring, shock absorber, and control arm into a single compact unit, effectively functioning as a damping and support mechanism in one assembly. This design provides several advantages, such as saving space and reducing overall weight, which can enhance vehicle performance and handling dynamics. The strut is mounted to the vehicle's body and connects to the wheel assembly, allowing for smooth motion during various driving conditions. This system is commonly used in many modern vehicles due to its efficiency in absorbing road shocks while maintaining proper wheel alignment.

Multi-link suspension setups, while sophisticated, consist of multiple links and do not combine the spring and shock absorber as a single unit. Coil spring suspension refers to a configuration that primarily uses coil springs for support but does not include the integration of shock absorbers and control arms in a compact design. Torsion beam suspension, generally found in simpler setups, links the wheels through a beam and is not compact in the same way as strut-type suspension systems.
