Technical Problem
相比于传统的液压制动系统，电子机械式制动系统有着更快的制动响应速度，更高的强度的优势，而目前现有的滚珠丝杠都不具有调心功能，因此在实际使用的过程中，无法很好的过渡卡钳制动时由于变形带来的径向力，降低了制动系统的效率
Benefits of technology
[0008]本实用新型通过丝杠端面球面调心槽与调心杆圆头结构的球面配合，使传动机构具备自适应调心能力，可吸收卡钳制动变形产生的径向偏载力，避免钢球与滚道受偏载磨损，改善传动效率与运行寿命；整体结构集成度高、轴向尺寸紧凑，可适配汽车轮边的狭小安装空间，满足电子机械式制动系统的使用需求。推力轴承结构可承载轴向载荷，保障传动过程的稳定性；弧面配合的支撑盘与垫片可进一步适配角度偏差，扩大调心范围；六角面配合结构可限制调心杆周向转动，保证传动精度。
