Modern cars use an array of sensors, which are essential for its operation. An example are electric vehicles, which require measuring of the rotation of the steering wheel axis. In this final paper, a sensor in the form of a potentiometer is examined. It should be installed in such a way that it is directly connected to the steering wheel. The first step was selecting the location of its installment and modelling it in a CAD environment. To install it a bracket was designed, which enables the attachment of the sensor in the vicinity of the position of measurement. As the subject of this thesis a belt drive with a timing belt was designed. It connects the steering wheel axis to the measuring axis of the potentiometer. Because of limited space the drive includes nonstandard pulleys. To provide tensioning of the timing belt an additional element was included. The pulley and bracket were manufactured using additive manufacturing. During production certain parameters were varied to achieve the adequate results. Different manufacturing technologies and finished parts are compared. After production the quality of the final products was inspected, and they were installed. A new sensor was successfully added to the automobile and its operation was ensured with the help of the belt drive.
