Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
A kind of double rolling key clutch; The utility model is like Fig. 1,2,3, shown in 4; A kind of double rolling key clutch comprises little mono-directional overrun clutch and big mono-directional overrun clutch, it is characterized in that: described little mono-directional overrun clutch joins with big mono-directional overrun clutch in the other direction.
In the present embodiment, little mono-directional overrun clutch comprises the interior cover 8 of the steamboat of wounded in the battle keyway, the cover 8 outer steamboat overcoats 13 that are with in the steamboat; Have semicylindrical opening 7 on the cover 8 in the steamboat, steamboat ratchet 1 is installed in the semicylindrical opening 7, also have spring eye 3 on the cover 8 in the steamboat; Be inserted with steamboat Spring Steel Wire 2 in the spring eye 3, the free end of steamboat ratchet 1 contacts with the free end of steamboat Spring Steel Wire 2, and the free end of steamboat ratchet 1 is positioned at steamboat Spring Steel Wire 2 free-ended outsides; The internal surface of steamboat overcoat 13 is designed with steamboat tooth 12, and steamboat ratchet 1 and steamboat tooth 12 be toe joint mutually, and ball 11 is housed in the steamboat overcoat 13; Be stamped steamboat end cap 9 on the steamboat overcoat 13, big mono-directional overrun clutch comprises cover 14 in the bull wheel, the cover 14 outer bull wheel overcoats 15 that are with in the bull wheel; Have semicylindrical opening on the cover 14 in the bull wheel, bull wheel ratchet 5 is installed in the semicylindrical opening, also have spring eye on the cover 14 in the bull wheel; Be inserted with bull wheel Spring Steel Wire 4 in the spring eye, the free end of bull wheel ratchet 5 contacts with the free end of bull wheel Spring Steel Wire 4, and the free end of bull wheel ratchet 5 is positioned at bull wheel Spring Steel Wire 4 free-ended outsides; The internal surface of bull wheel overcoat 15 is designed with bull wheel tooth 6, and bull wheel ratchet 5 and bull wheel tooth 6 be toe joint mutually, in the bull wheel overcoat 15 ball is housed; Be stamped bull wheel end cap 10 on the bull wheel overcoat 15; The opening direction of steamboat ratchet 1 and bull wheel ratchet 5 is opposite, and the fluting of bull wheel tooth 6 and steamboat tooth 12 is in the opposite direction, and cover 14 is an integral body with steamboat overcoat 13 in the bull wheel.
The utility model is installed on the pto of the mid-motor of electric motor car, its external structure be two-layer sprocket wheel as the power transmission device, in use the ball load and the power of reducing friction; Semicylindrical opening can limit the activity of steamboat ratchet and bull wheel ratchet, avoids deviating from voluntarily.
External structure can be used two-layer sprocket wheel or other transmission paries, and such as gear, belt pulley and friction wheel etc., its locking also comprises similar assembly with disengagement assembly steamboat ratchet and bull wheel ratchet, like inclined-plane, roller and noiseless ratchet etc.; The clutch action of steamboat and bull wheel is opposite, and the overcoat of steamboat promptly is the interior cover of bull wheel.
