Vehicle Components and Systems I

None

The development of competences in the various modules that constitute the curricular unit will be carried out through theoretical classes, theoretical-practical classes, and practices with description and discussion about the respective components, using as pedagogical supports several platforms, namely the internet and audiovisual media.

Knowing in theoretical and practical aspects the constitution, operation, technologies and processes of manufacturing vehicles and their respective systems of transmission, steering, braking, wheels and tires.
At the end of the course, students should be able to describe the constitution, operation, technologies and manufacturing processes of vehicles and their transmission, steering, braking, wheels and tires systems; they must also have knowledge of terminology, classifications, and vehicle categories.

1. VEHICLE DYNAMICS
