The invention belongs to the field of production of an automobile hub bearing unit and especially relates to a drive hub bearing unit spin riveting pressure measurement system and measurement method. The measurement system comprises an outer ring, an external steel ball, an internal steel ball, a flange plate, an external holder, an internal holder, a bolt and foil gauges. The system is reasonable in structure design and simple in measurement method, and can accurately measure axial pressure remaining on the hub bearing unit after the hub bearing unit finishes spin riveting process to determine axial pre-tightening effect under a bearing loading state, thereby preventing the problem of flange shaft rupture due to inner ring loosening and skid, and ensuring driving safety. The measurement can check reasonability of structure design of a spin riveting structure and select reasonable process parameters. 本发明属于汽车轮毂轴承单元生产领域，尤其涉及种驱动轮毂轴承单元旋铆压力测量系统及其测量方法。该测量系统包括外圈、外列钢球、内列钢球、法兰盘、外保持架、内保持架、螺栓和应变片。本发明结构设计合理，测定方法简便，并精准地测定
