Abstract

The utility model relates to a maneuver pedal dual-purpose power machine which comprises a motor, a rotor shaft of a sleeve barrel (2), a centre shaft (1), a planet speed reducing wheel train (4), a planet speed reducing wheel train (9), an external ratchet wheel (12), an internal ratchet wheel (14), a chainwheel shaft (13) and a chainwheel (15), wherein, the rotor shaft of a sleeve barrel (2) which is driven by the motor drives the chainwheel shaft (13) and the chainwheel (15) through the planet speed reducing wheel train (4), the planet speed reducing wheel train (9) and the external ratchet wheel (12). The centre (1) shaft which is driven by a pedal to rotate drives the chainwheel (15) and the chainwheel shaft (13) by the internal ratchet wheel (14). Two kinds of drive input do not influence each other and are conveniently exchanged because the internal and the external ratchet wheels are drivn in a single direction. When the utility model is used on a dual-purpose vehicle, the same chainwheel and the same chain can be shared to drive a wheel with the same speed ratio so as to drive a driving wheel. The utility model has the advantages of integral and compact structure, convenient and reliable operation and low cost.

Description

Motor-driven, pedal double-purpose engine

The utility model belongs to the mechanical ﹠ electrical technology field.

Use at present the engine on motor-driven, autocycle, generally be compact internal combustion engine or electrical motor, as the electric dual-purpose car, two kinds of power transmission processes of its electric pedal are, minor sprocket on the pto transmission shaft on the electrical motor, the big gear wheel of slowing down on the chain gear drive wheel drives the drive wheel walking, is deceleration transmission between output shaft and the drive wheel.When riding to power, the hinge wheel on the axis is through chain, and the minor sprocket on the transmission drive wheel drives the drive wheel walking, is the speedup transmission between axis and the drive wheel.So engine that uses on existing motor-driven, the autocycle, motor-driven and foot-operated transmission is independent separately, separate, promptly on power machine output shaft and foot-operated axis, the large and small sprocket wheel that does not wait is arranged respectively, increasing on chain gear drive wheel separately, reducing gear are to reach the motor-driven and foot-operated needed safe command speed that travels.This motor moped engine when power conversion, the switching mechanism complexity, in addition accessory is many, manufacturing cost is high, poor reliability.

The purpose of this utility model provides a kind of when motor-driven or pedal power conversion, a shared output shaft, sprocket wheel, and through same chain, motor-driven, the pedal double-purpose engine of change gear transmission drive wheel.

The utility model with as, technical scheme realizes that motor-driven, pedal double-purpose engine comprises, electrical motor, sleeve rotor shaft, axis, planetary reduction gear train, outer ratchet, handle ratchet wheel, sprocket shaft and sprocket wheel.Gear on the ro-tors in electrical quill shaft is passed on Gong the planetary reduction gear train through the sprocket shaft of ratchet forward drive sleeve in satellite gear center gear dish in addition that slow down, and driving chain wheel rotates.Axis with bearing fixing in the rotor sleeve axle, the handle ratchet wheel on the axis, reverse drive is enclosed within the outer sprocket shaft of handle ratchet wheel and rotates, foot-operated in during shaft drive because outer ratchet one-way transmission, sprocket shaft rotates the no longer planet circular system of driving chain wheel outer shaft sleeve.During electric motor drive, because the unidirectional messenger chain of handle ratchet wheel, wheel shaft rotates also the not interior axis of messenger chain wheel shaft.

Press that the utility model design-calculated is motor-driven, the pedal double-purpose engine, owing to used inside and outside ratchet device, when motor-driven transmission, outer ratchet drive sprocket shaft, and axis breaks away from rotation owing to the unidirectional transmission of handle ratchet wheel, and the planet circular system of handle ratchet wheel driving chain wheel during central shaft drive and motor-driven transmission is owing to outer ratchet one-way transmission breaks away from rotation.Simultaneously because the planetary reduction gear train is adopted in motor-driven transmission, the rotating speed that is transferred to sprocket shaft has reduced to ten sixths of motor speed, the sprocket wheel of shared foot-operated transmission and drive wheel gear, the speed of travel of its motor-driven transmission drive wheel meets the powered travel rate request fully for 2-3 times of foot-operated walking.

The utility model is owing to adopt the unidirectional transmission of handle ratchet wheel, outer ratchet one-way transmission and planetary reduction gear train, sprocket shaft motor-driven, and foot-operated transmission is not disturbed mutually, so it is motor-driven, when foot-operated transmission is changed, very convenient fast, do not need to add in addition any conversion steering unit and speed-changing mechanism.This is motor-driven, and the pedal double-purpose engine is suitable for using on electronic, the autocycle especially.

Fig. 1 is a kind of embodiment section-drawing of the present utility model.

Fig. 2 is Fig. 1 .A-A ' face section-drawing.

Fig. 3 is Fig. 1 .B-B ' face section-drawing.

Do following describing in further detail in conjunction with the embodiments according to above-mentioned accompanying drawing.

Axis 1 motor-driven, the pedal double-purpose engine is fixed in the motor sleeve rotor shaft 2 with ball bearing of main shaft, coaxial fastening gear 3 is arranged on the sleeve rotor shaft 2, three planetary wheels 4 on the gear 3 transmission planet circular system upper planet wheel discs, there is gear ring 5 planetary wheel 4 rotational trajectory outers, the rotating shaft 6 of three satellite gears is fixed on the planet wheel disc 7 of planet circular system, the rotation and on gear wheel shaft 10 of three planetary wheels 9 in the sun gear 8 transmission second stage planet circular systems on the wheel disc 7, satellite gear 9 along gear ring 5 rotation.Fixedly have on the planet wheel disc 11 of planetary wheel rotating shaft 10 and wheel disc 11 single-piece ring-type minor axises 12, have the zig-zag ratchet in the ring of minor axis 12, closed chain wheel shaft 13 holds and is engaged in minor axis 12 ring to roll stud shaft, and the two ends of ring diameter are very heavy with two of very heavy spring jack-up outside on the sprocket shaft 13.The interior ring of closed chain wheel shaft 13 also has the zig-zag ratchet.The axle sleeve 14 that is fixed on the axis 1 holds with closed chain wheel shaft 13 and cooperates to roll stud shaft, and the very heavy of two very heavy spring jack-up also arranged on the axle sleeve 14.Sprocket wheel 15 is fixed on the sprocket shaft 13.Electrical motor, planet circular system, inside and outside ratchet is wrapped in the casing 16, and the two ends of sprocket wheel 15 and axis are outside casing 16.

After electrical motor inserted power supply, the rotor sleeve axle slowed down through gear, planet circular system, and outer ratchet one-way messenger chain wheel shaft drives the sprocket wheel rotation.When PTO Power Take Off, axis two ends bonded assembly crank drove the axis rotation, the axle sleeve on the axis drove the sprocket wheel rotation through the unidirectional messenger chain wheel shaft of handle ratchet wheel.

1440 rev/mins of the utility model design motors speed, slow down 16 times through the secondary planet train, the chain wheel speed is 90 rev/mins, sprocket wheel 36 teeth, flywheel 18 teeth on the drive wheel, the drive wheel rotating speed is 180 rev/mins, and drive wheel adopts 22 cun-24 cun diameters, and the drive wheel speed of travel is 18.9KM/ inch-21.2KM/ inch.

Implement the utility model, can simplify Power train motor-driven, autocycle, make it integrated, realizes motor-drivenly riding, transmission transmits on same sprocket shaft.Power conversion is very convenient, and is reliable.Also reduce simultaneously the manufacturing cost of transmission device significantly.Can be widely used in motor-driven, foot-operated on the motor moped of power.
