Abstract

Though conventional hydraulic disc brake has better braking steadiness, it also has poor braking efficiency factor. As a fact, the conventional hydraulic disc brake has no large-scale application to heavy duty vehicle. A novel wedge disc brake is presented in this paper, which not only has the special characteristic of self-reinforcement, but also has better braking steadiness just like conventional disc brake. Firstly, the self-reinforcement principle of this kind of wedge disc brake is analyzed and concluded. The reasonable angle of wedge block is calculated and chosen according to the demand of self-reinforcement and unexpected self-lock phenomena. Based on that, the braking efficiency factor is derived from the wedge angle and the friction coefficient between the wedge block and brake disc. After that, the mechanical structure of designed wedge disc brake is presented, then some material strength of the components are revised. In order to validate this designed novel wedge disc brake, a AMESim vehicle model with Simulink wedge disc brake model are built. Several items such as the effect of self-reinforcement and reset of wedge block are simulated. Simulation results show that this novel wedge disc brake can generate the same brake force only at nearly one third multiple hydraulic pressure of conventional disc brake.
