Abstract

The utility model relates to an integral boosting device of a bicycle, comprising a casing, an engine comprising a cylinder, a crankshaft and a crankcase, a middle shaft, a middle shaft of the bicycle, a coaxial line, and a sleeve shaft sheathed on the periphery of the middle shaft in a sliding mode. The crankshaft is horizontally arranged, so the three shafts are parallel to each other. An overrunning clutch whose outer gear is a driving gear and a centrifugal clutch connected with the driving gear are arranged on the crankshaft. An underdriving gear set is positioned on the middle shaft. An end tooth clutch is arranged on the sleeve shaft. The shafts and the components of the shafts are positioned in the casing body; the casing and the crankcase are connected into an entirety. The utility model has the advantages of compact structure, reliable transmission, high transmission efficiency, convenient starting, convenient manipulation and convenient repair.

Description

Assembled energy saver of bicycle

The relevant Accelarators for bicycles of the utility model, especially relevant bicycle integral type servo-unit.

The more employing bicycle middle shaft of Accelarators for bicycles chain transmission mode because of this type of drive reliable transmission, and also has certain cushion characteristic.

Yet, the Accelarators for bicycles of present this employing chain gear is generally split type, put-put and the reduction gear apparatus of promptly forming Accelarators for bicycles are respectively two individual components, be connected with belt pulley by belt between the two and carry out transmission of power, not only there is the not compact problem of structure in this, and owing to increased belt and pulley drive link, driving efficiency is reduced, and the belt transmission is easily skidded, especially in the sleet sky, because of slipping of the belt, often cause servo-unit can not send enough driving power.In addition, separately make, also be unfavorable for improving servo-unit overall performance and anufacturability because servo-unit is divided into two individual components.

Therefore, the utility model purpose is to provide compact conformation, reliable transmission, driving efficiency height, easy to operate bicycle integral type servo-unit.

Integral type servo-unit according to the utility model bicycle, comprise housing, comprise cylinder, piston crank mechanism, the put-put of bent axle and crankcase, tween drive shaft and bicycle middle shaft, and the above-mentioned overriding clutch on each in position respectively, centrifugal clutch, under drive gear group and output clutch, above-mentioned bent axle, tween drive shaft, bicycle middle shaft is level and is parallel to each other, comprise coaxial line in addition, sliding sleeve is positioned at the sleeve of bicycle middle shaft periphery, described under drive gear group comprises driving gear, train of reduction gears and output gear, its foreign steamer is that the overriding clutch of described driving gear is fixed on the described bent axle successively with the centrifugal clutch that its foreign steamer links to each other with described driving gear, above-mentioned output clutch is positioned on the described sleeve, described train of reduction gears comprises the reducing gear parts that are positioned on the tween drive shaft, these above axles and be positioned at parts on shaft and all be positioned at described housing, in addition, also comprise the output chain gear that is positioned on outer described sleeve one end of described housing, and be fixed on bicycle middle shaft one end, the ratchet device that is fixedly linked with described output chain gear.

Followingly the utility model example structure is described with reference to accompanying drawing.

Fig. 1 is the figure that schematically illustrates the utility model embodiment overall structure.

Among the figure, 19 is the utility model bicycle integral type servo-unit housing, and and following crankcase 18 fuses, put-put is substantially by cylinder 17, crankcase 18, piston crank mechanism 16 and bent axle 1 are formed, in addition, on an end of bent axle 1, also fixedly install flywheel 12 and magneto generator 13.Bent axle 1 is arranged to level, 2 is tween drive shaft, 3 is bicycle middle shaft, these maintenances are parallel to each other, 14 for axis 3 coaxial lines, be positioned at the sleeve of axis 3 peripheries, 10 and 11 are the centrifugal clutch that is fixed on the bent axle successively, overriding clutch and its foreign steamer that its foreign steamer is drive gear teeth 9 link to each other with driving gear 9, on tween drive shaft 2, set gradually and free rotating reducing gear to overlap 7,8, setting gradually on sleeve 14 can free rotating geared sleeve 15 and the output clutch of being with output gear 6.

In the present embodiment occasion, this output clutch is a terminal formula power-transfer clutch 5, band output gear 6 on its terminal on one side, be with hole, a plurality of garden on the end face that makes output gear 6 but also can adopt in addition, on sleeve 14, fixedly install in addition the disk that can combine with output gear 6, with latch make this disk and output gear in conjunction with or the separated structures form; Above-mentioned train of reduction gears also can only comprise the reducing gear cover that is positioned on the tween drive shaft 2, as long as reduction ratio is met design requirement.Present embodiment makes the pinion of output gear 6 and geared sleeve 7 respectively, the pinion of the big gear wheel of geared sleeve 7 and geared sleeve 15, the pinion of the big gear wheel of geared sleeve 15 and geared sleeve 8, the big gear wheel of geared sleeve 8 and driving gear 9 engagements.

Effect to the utility model servo-unit structure describes below.As mentioned above, when Accelarators for bicycles is in riding condition, the starting that tramps with one's feet, this gyroscopic movement drives bent axles 1 through ratchet device 4, sleeve 14, contrate-gear-type clutch 5, output gear 6, geared sleeve 7, geared sleeve 15, geared sleeve 8, driving gear 9 and overriding clutch 10 and makes gasoline starting.

After the engine petrol starting, when power raises when bent axle 1 rotating speed through bent axle 1, centrifugal clutch 11(, overriding clutch is inoperative, replacing centrifugal clutch works), driving gear, geared

sleeve

8,15 and 7, contrate-gear-type clutch 5, sleeve 14, to output chain gear 20(ratchet device this moment is clockwise, and axis 3 does not rotate).Drive bicycle rear revolution by chain this moment.

When the bicycle use manpower is ridden, depress the bar handle (not shown) of contrate-gear-type clutch, contrate-gear-type clutch is separated, power is through pedal, bicycle middle shaft 3, ratchet device, arrival output chain gear.Drive bicycle rear revolution by chain this moment.Sleeve revolution this moment, but because of contrate-gear-type clutch is in released state, reducing gear is motionless, and riding this moment, firmly degree is identical with ordinary bicycle or similar.

Zong the above, the utility model Assembled energy saver of bicycle has compact conformation, transmission of power is reliable, transmission efficiency is high, starting and riding manipulation and Wei Xiu be the obvious You point such as very convenient.
