Patent ID: 10760625

Abstract:
A double-ratchet type one-way clutch, in which pawls do not knock the surfaces of ratchets when the double-ratchet type one-way clutch rotates in an idling direction, mainly comprises: a driving ratchet, a driven ratchet set, a pawl set, and rolling bearings. The pawl set comprises: a pawl base cover, a plurality of pawls, and a plurality of elastic elements. The driven ratchet set comprises: a ratchet of the driven ratchet set, balls, a ball cage, and a driven ratchet set supporting ring. When the double-ratchet type one-way clutch rotates in the idling direction, the driving ratchet firstly rotates relative to the ratchet of the driven ratchet set. After a top tooth surface of the ratchet of the driven ratchet set and a top tooth surface of the driving ratchet are complementary in an axial direction, the driving ratchet drives the ratchet of the driven ratchet set to rotate together.
