针对传统盘式制动器制动"热衰退"和液压制动响应慢等问题,综合汽车摩擦制动与电涡流制动的工作原理,实现电磁摩擦一体化制动器的创新设计。基于电磁感应定律,推导了集成制动器制动力矩公式,为磁场分析提供了理论基础。应用Ansoft Maxwell对电磁制动部分磁感应强度分布情况及制动力矩响应曲线进行了分析。仿真结果表明,集成制动器电磁制动部分可以得到较大制动力矩,可以有效的分担部分摩擦制动的负担,降低"热衰退"。

Aiming at the problem of traditional disc brake"heat fade"and hydraulic brake response is slow,Comprehensive consideration the friction brake and eddy current brake working principle,completed the design of electromagnetic-friction integrated brake innovation.Based on the law of electromagnetic induction,the formula of integrated brake torque is deduced,provides a theoretical basis for the analysis of magnetic field.Applied Ansoft Maxwell electromagnetic brake part of the magnetic induction intensity distribution and braking torque response curves are analyzed.and the simulation results show that integrated brake the electromagnetic braking scheme can obtain certain braking torque,can effectively share the part of the friction brake,reduce the“heat fade”.
