Abstract:
A power steering system in which an output shaft of a driving unit and an input shaft of a steering unit that produces a rotational torque in response to an impact force transmitted by the steering unit are coupled via a torque limiter, the torque limiter comprising:a substantially-cylindrical limiter cover with a bottom, the limiter cover combined with and rotatable together with one of the output shaft and the input shaft; anda limiter plate contained within the limiter cover, the limiter plate being combined with and rotatable together with the other of the output shaft and the input shaft;a forcing member supported by the limiter cover for forming the limiter plate toward the limiter cover;a supporting member for supporting the forcing member fit in a concave portion formed in an inner-peripheral area of the limiter cover; and whereinthe torque generated by impact force transmitted from the steering unit is absorbed by the sliding action generated by rotation of the limiter cover relative to the limiter plate.
