Course detail
Gearing Devices of Vehicles
FSI-QRU Acad. year: 2025/2026 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.

Entry knowledge
Basic knowledge corresponding to subjects of theoretical foundations of bachelor study at FME BUT, especially statics, kinematics, dynamics, elasticity and strength.
Rules for evaluation and completion of the course
The course-unit credit is conditional on active participation in the exercises and passing the credit test with the achievement of more than half the number of points.
The exam verifies the knowledge gained in lectures and seminars, is written and in case of necessity also oral.
The basis for the overall grade is the point evaluation of the written and possibly oral part of the exam, as well as points from the credit test and voluntary semester work.
Exercises are compulsory, the form of replacing the missed lessons is solved individually with the lecturer or with the course guarantor.
Aims
The aim of the course is to acquaint students with the problem of transmission of torque from powertrain unit 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.
By completion of this course, the student will acquire knowledge that is a prerequisite for independent design work in the field of vehicle transmissions, the ability to evaluate and optimize design designs from the point of view of their practical implementation.
