Abstract
MOHD-RAZMI, Ishak et al. Brake torque analysis of fully mechanical parking brake system: Theoretical and experimental approach. Ing. invest. y tecnol. [online]. 2018, vol.19, n.1, pp.37-49. ISSN 2594-0732. https://doi.org/10.22201/fi.25940732e.2018.19n1.004.
The effect of the reduction of drum brake temperature on the clamping force of the parking brake system has not been well addressed despite the fact that it may result in vehicle roll away. In view of this, parking brake model that takes into account the temperature reduction of the drum brake has to be developed and more importantly, it must comply with the applicable standards or regulations such as FMVSS 135. This paper develops a one dimensional (1D) model of leading-trailing drum-type parking brake model. This brake model is then verified with experiments carried out on a test bench that has been calibrated with the hand brake system in the vehicle. The results from the experiments show a good correlation with the predicted results from the brake model. With the verified brake model, parametric studies can be carried out as one of the tools during the design process.
