Comparison of Various Concepts of Twin Leading Brake Performance by Method of Virtual Simulation 2014-01-2500

Prevailing cut-throat competition in Indian Two wheeler market requires design engineers to enhance performance of traditional braking systems with reduction in cost and weight. The increasing need of road safety however requires the braking system to minimize stopping distance and increasing Mean Fully Developed Deceleration (MFDD). The purpose of this study is to augment the braking performance of two wheeler by comparing various combinations of twin leading drum brake layouts by method of Virtual Simulation.
The conventional drum brake system utilizes one cam, one pivot, one leading shoe member and one trailing shoe member. In the event of braking, leading shoe causes the generation of drag force. The other shoe is “trailing”, moving against the direction of rotation, is thrown away from the friction surface of the drum and is far less effective. The present study highlights the incorporation and enhancement of braking characteristics of bigger brake drum system into smaller brake drum system through the adoption of double leading shoe concept with the added advantage of reduction in cost. The study necessitates the designing of a multi body dynamic model so as to extract the best braking performance with respect to typical braking system against different double leading shoe geometry and actuation mechanisms.
