Gearing Devices of Vehicles (FSI-QRU)

Academic year 2021/2022
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 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.
Learning outcomes and competences:
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.

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:
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.
Controlled participation in lessons:
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
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Laboratory exercise  6 × 2 hrs. compulsory                  
    Exercise  7 × 2 hrs. compulsory
