Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
A kind of double rolling key clutch, the present invention is shown in Fig. 1,2,3,4, 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 and big mono-directional overrun clutch join 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, the free end of steamboat ratchet 1 is positioned at steamboat Spring Steel Wire 2 free-ended outsides, the internal surface design of steamboat overcoat 13 has steamboat tooth 12, steamboat ratchet 1 and steamboat tooth 12 be toe joint mutually, 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, the free end of bull wheel ratchet 5 is positioned at bull wheel Spring Steel Wire 4 free-ended outsides, the internal surface design of bull wheel overcoat 15 has bull wheel tooth 6, 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 direction of bull wheel tooth 6 and steamboat tooth 12 is opposite, and cover 14 is an integral body with steamboat overcoat 13 in the bull wheel.
The present invention 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, as inclined-plane, roller and noiseless ratchet etc.; Steamboat is opposite with the clutch action of bull wheel, and the overcoat of steamboat promptly is the interior cover of bull wheel.
Use when of the present invention, cover initiatively just changes in the steamboat, the steamboat ratchet embeds the steamboat tooth and locks, driving the steamboat overcoat just changes, cover 14 is an integral body with steamboat overcoat 13 in the bull wheel, cover 14 is same with steamboat overcoat 13 in the bull wheel, be that cover 14 is just changeing in the bull wheel, because the opening direction of steamboat ratchet 1 and bull wheel ratchet 5 is opposite, the fluting direction of bull wheel tooth 6 and steamboat tooth 12 is opposite, so bull wheel ratchet 5 is squeezed away by the bull wheel tooth of bull wheel overcoat 15 internal surfaces and can not lock, then bull wheel overcoat 15 does not change, otherwise, bull wheel overcoat 15 initiatively just changes, and bull wheel ratchet 5 embeds the bull wheel tooth of bull wheel overcoat 15 internal surfaces and locks, and driving the interior cover 14 of bull wheel is that steamboat overcoat 13 is just changeing, steamboat ratchet 1 is squeezed out by the steamboat tooth of steamboat overcoat internal surface and can not lock, and cover does not change in the steamboat.
The present invention can be applied in the electric motor car, the present invention is installed on the motor power output shaft, wherein the steamboat among the present invention is connected with trailing wheel with chain, trailing wheel is mounted on the rear-wheel spindle, and its bull wheel is connected with the pedal axle bull wheel by chain, and the pedal axle bull wheel is mounted on the pedal axle, when the motor power output shaft initiatively just changes, the steamboat overcoat of the double rolling key clutch of installing on it just changes because of the locking of steamboat ratchet thereupon, and driving trailing wheel with chain just changes, and electric motor car moves ahead; This moment, the bull wheel overcoat of double rolling key clutch did not rotate because of the disengagement of bull wheel ratchet, and pedal axle sprocket wheel and pedal axle all do not rotate.Otherwise, when pedal axle is initiatively just changeing owing to riding, the pedal axle bull wheel just changes because of the one fixed installation thereupon, and the bull wheel overcoat that drives in the double rolling key clutch by chain just changes, and because of the locking of bull wheel ratchet, the steamboat overcoat of double rolling key clutch is just changeing thereupon and driving trailing wheel with chain and just changeing, electric motor car moves ahead, throw off because of double rolling key clutch steamboat ratchet this moment, and motor output shaft does not change, and promptly motor does not change.
