A Calculating Method for Braking Toque of Vehicle Brake

In calculating the braking torque of a brake, the braking efficiency factor method is often used. In the paper, the formulae for calculating braking toque of leading shoe and trailing shoe brake are analyzed. Although they are different in forms with different parameters, these formulae can be changed into the same form,which shows that they are identical.Examples shown also verify this.In fact these formulae are all based on the same hypothesis,i.e.,both drum and shoe are inflexible and the unit pressures between them are of sinusoidal distribution.Some proposals for choosing among them are also given.
