Gearing Devices of Vehicles (FSI-QRU)

Academic year 2024/2025
Supervisor: Ing. Aleš Prokop, Ph.D.  
Supervising institute: ÚADI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:

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.
Learning outcomes and competences:
 
Prerequisites:
 

Links to other subjects:
compulsory co-requisite: Driving Mechanisms [QHL]
compulsory co-requisite: Tractors [QT]
Course contents:

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.
Teaching methods and criteria:
 
Assesment methods and criteria linked to learning outcomes:

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.
Controlled participation in lessons:
 
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Laboratory exercise  4 × 2 hrs. compulsory
