集成驻车式后制动钳回敲研究

Research on the Integrated Parking Brake Caliper Knock Back

文章介绍了引起制动钳回敲的两种工况,深入分析集成驻车式后制动钳的工作原理,分别建立活塞、调整螺母及密封缸的受力分析方程,推导制动钳回敲产生的机理;进行道路载荷谱采集,构建双向共振试验台架,建立制动钳回敲的室内整车模拟台架试验方法;以某回敲的制动钳为例,描述了如何进行钳体结构参数优化设计,彻底解决该问题的发生。

The cause of two kinds of brake caliper knockback is introduced, and the principle of integrated parking brake caliper is analyzed. Respectively, the force analysis of piston, the adjusting nut and seal cylinder equation is set up, and the mechanism of brake caliper knock back is derived. The road load spectrum is collected, two -way resonance test bench is built, and the indoor vehicle braking caliper to knockback simulation bench test method is established. Taking a knockback brake caliper for example, how to optimize the caliper structural parameters is described, and the problems are completely solved.
