Influence of vanes shape on flow velocity of ventilated disc in heavy truck braking

Abstract

Today, the ventilated disc brakes are the most common type of disc brakes used on road vehicles, especially on heavy-duty vehicles. The reason for such wide application mainly lies in the fact that they allow the best dissipation of heat that is generated during brake process. The influence of vanes shape on air flowing velocity trough the disc, and pressures that occur as consequence of air flowing, and the influence of disc speed on air flowing velocity is studied in this paper. Air disc brakes for heavy duty commercial vehicle applications with three types of vanes shape are analysed. The analysis how disc speed influencing on air flow velocity
