Learning Objectives

Indicator: 2.1.2.LI.5 - Describe an independent suspension system and its working principles

By the end of the lesson, learners can:

Define independent suspension and distinguish it from the rigid beam suspension system studied in Week 5.
Sketch and label the key components of both the double wishbone and Macpherson strut suspension systems.
Compare the construction and working principles of the wishbone and Macpherson type suspensions, identifying the advantages and disadvantages of each.
Explain how each wheel responds independently to road irregularities using the principles of geometry and linkage movement.
Justify the choice of one independent suspension type over another for a given vehicle application based on criteria such as cost, space, ride comfort, and handling.
