| description | The invention discloses an ultrasonic suspension hub bearing of an electric automobile. The ultrasonic suspension hub bearing comprises piezoelectric transducers, a bearing box and a retainer assembly, the piezoelectric transducers are mounted on three small box bodies of the bearing box; the retainer assembly is mounted in a circular through hole of the bearing box; each piezoelectric transducercomprises a radiation head, an amplitude-change pole, an insulating sleeve, a rear cover plate and a prestressed bolt; the bearing box comprises a hexagonal box body and the three small box bodies; and the retainer assembly comprises two groups of large retainers, two groups of small retainers and balls. According to the ultrasonic suspension hub bearing of the electric automobile, friction between shafts can be reduced by utilizing the antifriction characteristic of ultrasonic vibration, friction heat generated in the operation process is reduced, the ultrasonic suspension hub bearing is superior to a double-row angu |
