Abstract:
In order to study the mechanical performance of leading-trailing brake system accurately with an opening device by a cam, this paper builds the finite element model of floating-shoe brake. The braking process of the brake system is simulated by applying the input torque on the cam axis. The friction contact between brake lining and drum is analyzed, and the contact stress cloud-chart, as well as distribution curve of brake torque are gotten. This paper also analyzes and compares it with the traditional shoe brake. The results indicate that: the leading-shoe's contact stress of floating-shoe brake is less than the traditional one, because of its larger contact area in the condition that brake torque keeps invariant. As the trailing shoe floats upward, the trailing shoe's friction torque of floating-shoe brake is larger than the traditional one. The total brake torque of floating-shoe brake is larger than the traditional one. 2 tabs, 9 figs, 6 refs.
