The specific embodiment

For making the inspector can further understand structure of the present utility model, feature and purpose thereof, the attached now detailed description with graphic and preferred embodiment as after.

Wherein, Fig. 1 is the front elevation of the engine hookup mechanism of the utility model power bicycle, Fig. 2 is the A-A section-drawing of engine hookup mechanism shown in Figure 1, Fig. 3 is the B-B section-drawing of engine hookup mechanism shown in Figure 1, and Fig. 4 is that engine hookup mechanism shown in Figure 3 is wherein in order to the scheme drawing of the handle axostylus axostyle of actuating spindle power-transfer clutch.

Shown in these were graphic, the engine hookup mechanism of the utility model power bicycle included an engine apparatus 1, one electronic starter gear 2, a transmission fluted disc device 3 and a foot pedal apparatus 4.

Above-mentioned this engine apparatus 1 has a bent axle 11, first end of this bent axle 11 and second end are respectively equipped with one first unidirectional automatic clutch device 12 and one second unidirectional automatic clutch device 13, and are equiped with one first unilateral initiative gear 14 and one second unilateral bearing starter toothed wheel 15 respectively.

Above-mentioned this electronic starter gear 2 has a starter motor 21, and the output shaft of this starter motor is provided with an output gear 22, and this output gear is engaged to the first unilateral initiative gear 14 of this engine apparatus behind an intermediate gear 23.

Above-mentioned this transmission fluted disc device 3, has a transmission fluted disc 31, this transmission fluted disc 31 is meshed with the second unilateral bearing starter receiver 15 of engine apparatus 1, this transmission fluted disc device 3 also is integrally formed with a transmission gear 32 and a unidirectional transmission flywheel 33, can combine with following toothed disc 47 and unilateral initiative flywheel 43 respectively.

Above-mentioned this foot pedal apparatus 4 has a pedal shaft 41, its both sides respectively are provided with a pedal 42, and be respectively equipped with a unilateral initiative flywheel 43 and be provided with a unidirectional drive flywheel 44 via an engagement sleeve 44a, and the periphery of this pedal shaft 41 is provided with a shaft clutch 45, this shaft clutch can be according to leader's axostylus axostyle 46 control its move axially and lotus root is bonded to a toothed disc 47 or leave this toothed disc 47, this toothed disc 47 is engaged to above-mentioned this transmission gear 32.Unilateral initiative flywheel 43 is bonded to unidirectional transmission flywheel 33 through a driving chain 48 chains, and unidirectional drive flywheel 44 then is bonded to a wheel shaft (for example rear axle of bicycle, not icon) through a chain drive-belt 49 chains.

When desiring power by engine apparatus 1 and advance, operating handle axostylus axostyle 46 makes and drives shaft clutch 45 lotus roots and be bonded to toothed disc 47, makes the transmission of power generation connection relationship of foot pedal apparatus 4 and engine apparatus 1.

When the electronic startup of desire engine apparatus 1, the starter motor 21 of electronic starter gear 2 is started, then can be in regular turn via output gear 22, intermediate gear 23 and the first unilateral initiative gear 14, and the bent axle 11 that starts this engine apparatus 1 rotates.This engine apparatus 1 is after startup and importing fuel (gasoline or gas) acceleration, then the rotary power of this engine apparatus can advance and bicycle is rotated automatically in regular turn via the first unidirectional automatic clutch device 12, the second unilateral bearing starter receiver 15, transmission fluted disc 31, transmission gear 32, toothed disc 47, shaft clutch 45, pedal shaft 41, engagement sleeve 44a, unidirectional drive flywheel 44 and chain drive-belt 49.

Desire with foot-operated when starting engine apparatus 1 in for example unregulated power, then its foot-operated power will drive unilateral initiative flywheel 43, driving chain 48, unidirectional transmission flywheel 33, transmission fluted disc 31 and 15 rotations of the second unilateral bearing starter receiver, and start bent axle 11 rotations of engine apparatus 1.This engine apparatus 1 is after startup and importing the fuel acceleration, then the rotary power of this engine apparatus advances and bicycle is rotated automatically also in regular turn via the first unidirectional automatic clutch device 12, the second unilateral bearing starter receiver 15, transmission fluted disc 31, transmission gear 32, toothed disc 47, shaft clutch 45, pedal shaft 41, engagement sleeve 44a, unidirectional drive flywheel 44 and chain drive-belt 49.

In the time of can't advancing automatically in the energy of for example engine apparatus 1 is exhausted, or the bicycle knight wants to change to rely on oneself and tramples when advancing, operating handle axostylus axostyle 46 makes shaft clutch 45 leave toothed disc 47, then foot pedal apparatus 4 is promptly removed and the connection relationship of engine apparatus 1 on transmission of power, therefore, bicycle knight's stampede power does not need to be used for simultaneously to bear all members that drive engine apparatus 1, becomes 100% bicycle completely, thereby can alleviate stampede power significantly.

The above person, it only is a preferred embodiment of the present utility model, be not to be used for limiting the scope that the utility model is implemented, such as the equalization of doing according to the described shape of the utility model claim, structure, feature and spirit changes and modifies, and all should be included in the claim of the present utility model.
