Abstract

The invention belongs to the technical field of automobile hub bearings, and particularly relates to an integrated automobile hub bearing based on fiber bragg grating sensing and a manufacturing method of the integrated automobile hub bearing. The integrated automobile hub bearing based on fiber bragg grating sensing comprises an automobile hub bearing body, a fiber bragg grating sensing system and a fiber bragg grating demodulator. The automobile hub bearing is a third-generation automobile hub bearing with a double-row structure, the fiber bragg grating sensing system is fixedly installed onthe hub bearing so as to monitor the temperature and the strain state of an outer ring of the automobile hub bearing, and the fiber bragg grating demodulator is connected with the fiber bragg gratingsensing system and used for displaying test data. The integrated automobile hub bearing is manufactured by fully utilizing the one-line multi-point advantage of the fiber grating sensor based on theintegrated automobile hub bearing based on fiber grating, so that the multi-point synchronous test of temperature and strain can be realized.
