Course detail
Gearing Devices of Vehicles
FSI-QRU Acad. year: 2021/2022 Winter semester
The course acquaints students with basic gear mechanisms of motor vehicles, their purpose, principle of function, construction and current state of development. The theoretical, constructional and operational aspects are taken into the account. During the lessons, presentation materials of functional samples provided by industrial partners and experimental technology in laboratories are used.

Learning outcomes of the course unit
By completion of this course, students will acquire knowledge that is a prerequisite for independent design activity, the ability to evaluate and optimize design proposals in terms of their practical implementation.
Prerequisites
Basic knowledge corresponding to subjects of theoretical foundations of bachelor study at FME BUT, especially statics, kinematics, dynamics, elasticity and strength.
Planned learning activities and teaching methods
The course is taught in the form of lectures that have the character of explanation of basic principles and theory of the given discipline. The exercise is focused on practical mastery of the subject topics covered in the lectures. Teaching is complemented by laboratory exercises.
Assesment methods and criteria linked to learning outcomes
The course-unit credit is awarded on following conditions: – active attendance in the seminars, – elaborated reports, – passed a credit test. The exam verifies the knowledge gained in lectures and seminars, is written and in case of necessity also oral.
Language of instruction

Aims
The aim of the course is to acquaint students with the problem of transmission of torque from vehicle engine to vehicle driving wheels. The aim is to obtain a comprehensive idea of the individual possibilities of conceptual-design solutions of partial components of the drivetrain.
Specification of controlled education, way of implementation and compensation for absences
Attendance in the seminars and laboratories is required and controlled by teacher. The form of compensation the attendance for serious reasons of absence is solved individually with the course supervisor, mostly by elaboration of substitute tasks
