    • 摘要: To meet the requirements of the automated production of motorcycle brake block,clamp the friction plate and horseshoe-shaped aluminum block and maintain pressure under high temperature,a kind of cam-slider clamping apparatus was designed in this paper,maintaining pressure between friction plate and brake block.The effect of cam speed and transmission speed on clamping force was gained through simulated analysis analyzed of different operational speed on the clamping force,through kinematics and dynamics simulation of clamping mechanism.Coupling analysis of temperature field and stress field was conducted in the thermal insulation box for the brake block in clamping state to gain the displacement changes of clamping mechanism and work piece.Thermal-structural coupling analysis of the clamping apparatus was conducted to analyze the change in displacement of the various components of the clamping mechanism,with the help of the finite element software,in the incubator.The results of the simulation demonstrate that the displacement of the slider in the thermal-structural coupling state was 0.7 mm larger than that in the normal temperature structural state,and leading clamping force to increase by 1 1 .6 N. Owing to the special structural characteristics of clamping mechanism,the change of clamping force will not affect normal loosening of clamping mechanism,so this kind of clamping mechanism,in the paper,can release normally in spite of the change of clamping force, thus working properly meet working requirements under high temperature environment.%为了满足摩托车制动蹄自动化生产要求,实现摩擦片与蹄形铝块之间夹紧并在高温下保压,设计了一种凸轮滑块式夹紧机构。通过对夹紧机构运动学和动力学仿真分析,获得了凸轮转速和输送速度对夹紧力的影响。对夹紧状态下的制动蹄在保温箱内进行温度场和应力场耦合分析,得到夹紧机构和工件的位移变化情况。结果表明:在热-结构耦合状态下夹紧滑块位移较常温下增加了0.7 mm,夹紧力增大了11.6 N。由于夹紧机构的结构特点,夹紧力的变化不会影响夹紧机构的正常松开,故该夹紧机构能满足高温环境下的工作要求。

    • 摘要: 介绍了重型卡车车桥用STR后制动蹄的铸件结构及技术要求,并详细阐述了原铸造工艺及存在的问题.为解决铸件出现的夹渣、缩孔问题,进行了分析和对比试验,得出以下结论:(1)制动蹄属于壁厚相对均匀的球墨铸铁件,采用无冒口、分散内浇道进铁液工艺能防止缩孔缺陷;(2)在挡渣效果不良的浇注系统内设置SiC陶瓷过滤器能较好地解决STR后制动蹄夹渣缺陷问题;(3)在保证不出现其它缺陷的前提下,严格控制浇注温度和化学成分对铸件的稳定生产很重要.

    • 摘要: 为评估某鼓式制动器的制动蹄在提高制动气压使用时的可靠性,应用ANSyS Workbench建立了该制动蹄的弹塑性有限元分析模型,并对制动气压提高前后制动蹄的结构强度进行了计算和比较。计算结果表明,制动气压提高后从蹄强度不足,在其滚轮轴支耳根部容易产生破坏。根据有关计算结果,对制动蹄进行了设计改进,得到了可以满足使用要求的结构方案。
