Abstract
The motor driver unit for bike or tricycle is composed of drive gear, driven gear and drive motor. Said driven gear is installed to back wheel. Its advantages are simple structure, small size, light weight and saving labour because the number of teeth for drive gear is very less than that of driven gear.
Description
The present invention relates to a kind of bicycle motor actuating device.
At present bicycle is one of comparatively main vehicle of generally using of China cities and towns and cottar, and use amount is very big.The engine installation of past electric bicycle is constituted with the coaxial chain-wheel mechanism of permanent-magnet disk wound motor and motor siamesed multi-stage gear speed reduction gearing and the output shaft of speed reduction gearing mostly.This engine installation complex structure needs through multi-stage speed-reducing; Weight is big, can only be installed on the special-purpose vehicle frame; Commonality is poor, is not suitable for ordinary bicycle, uses inconvenience also not light reliable.
The objective of the invention is to overcome above-mentioned defective, provide a kind of simple in structure, in light weight, can be installed on the ordinary bicycle, simple installation, use bicycle motor actuating device light, flexibility and reliability.
Purpose of the present invention is achieved through the following technical solutions: it is to be made of ring gear, driving gear, drive motor etc.Ring gear is fixedly installed on the bicycle rear, driving gear and ring gear engagement, driving gear is contained on the output shaft of drive motor, is provided with gear reduction in the drive motor, is provided with free-wheel clutch in the junction of driving gear and drive motor.
Bicycle motor actuating device of the present invention has simple in structure, and volume is little, and is easy for installation, uses light, flexible, reliable characteristics.Apparatus of the present invention are installed does not have special structural requirement to cycle frame, and apparatus of the present invention are taken turns on the wooden handcart applicable to bicycle, the three-wheel vehicle and two of disposable type and structure.The utility model device is installed on ordinary bicycle, ordinary bicycle can be transformed into the motor-driven bicycle.Now all in the world electric bicycle and motor bikes have all been ignored the most important on aufbauprinciple, i.e. the size of driving wheel and follower, and biggest advantage of the present invention just is the most laborsaving, because driving wheel is very little, follower is very big.
Fig. 1 is the structural representation of ring gear embodiment 1 of the present invention.
Fig. 2 is the structural representation of ring gear embodiment 2 of the present invention.
Fig. 3 is the structural representation of ring gear embodiment 3 of the present invention.
Fig. 4 is a kind of structural representation of the free-wheel clutch of drive motor and driving gear junction.
Fig. 5 is the fundamental diagram that has the drive motor of pull bar and gear reduction.
The structure of ring gear has three kinds among Fig. 1, and wherein Fig. 1 is the structural representation that is installed on the internal-gear type ring gear on the bicycle rear steel ring.Fig. 2 is the structural representation that is installed on the internal-gear type ring gear on the bicycle rear steel wire head.Fig. 3 is the structural representation that is installed on the tooth-like ring gear of face on the bicycle rear steel wire head.Ring gear 1 structure of Fig. 1 is flat, about the about 2mm of the thickness of gear, the diameter of the bicycle rear of diameter and required installation is complementary, and is distributed with bolt hole 1 '-1 at gear edge, by bolt with ring gear 1 ' be fixed on the bicycle rear steel ring that has openning hole in advance.The ring gear 1 of Fig. 2 " be Fig. 1 ring gear 1 ' architecture basics on, gear 1 ' the edge set up convex edge 1 " 1, make ring gear 1 " be formula, " have on 1 can for the recess 1 that links to each other with bicycle rear steel wire head "-2 in the convex edge 1.Ring gear 1 of Fig. 3 is a tubulose, and it also is provided with the part that links to each other with bicycle rear steel wire head, and the structure of this part is similar to figure's, the tooth of its ring gear 1 be distributed in gear axially on.Ring gear 1 of the present invention except can adopt internal-gear type, face tooth-like, also can adopt external tooth type, the structure of external tooth type ring gear basically with the structural similitude of Fig. 1 and Fig. 2.
Driving gear 2 and ring gear 1 engagement, the number of teeth of driving gear is far smaller than the number of teeth of ring gear.As shown in Figure 4: driving gear 2 is enclosed within on the output shaft 3-1 of drive motor 3, drives the driving gear rotation by drive motor 3.As shown in Figure 4: be provided with the centering block of controlling by spring 5 that swings up and down 6 in the end of drive motor axle shaft 3-1, have the groove 7 that matches with centering block 6 at the core wheel place of driving gear 2.By spring 5, the free-wheel clutch that centering block 6 and groove 7 are formed between driving gear 2 and the drive motor 3.This free-wheel clutch can stop power driven with drive motor 3 at rider, and during merely with manpower pedal's powered vehicle, when perhaps adding that with the power of drive motor 3 manpower pedal comes common powered vehicle, can make the rotation of driving gear not influence the rotation of drive motor.As shown in Figure 5: in order when drive motor does not have electricity, to overcome the transmission resistance between driving gear and ring gear, can be provided with at the shell surface of drive motor 3 one with drive motor output shaft bonded assembly pull bar 4, by engagement or the jump out of mesh of pull bar 4 control driving gears 2 with ring gear 1.In drive motor 3, also be provided with gear reduction, make the rotating speed of drive motor output shaft drop to a certain particular value.The drive motor that different users can have different gear reduction ratios according to the needs selection of oneself, drive motor is once selected, and the speed of a motor vehicle promptly is fixed.Drive motor of the present invention both can adopt DC machine also can adopt the gasoline motor.Use for convenience, in DC machine, also be provided with the electronic stepless speed regulation device, make the speed of a motor vehicle adjustable.Bicycle or three-wheel vehicle or two are taken turns one or two drive motor can be installed on the wooden handcart.
Ride the bicycle that apparatus of the present invention are housed, 3,4 circles that should tramp with one's feet earlier after getting on the bus, the switch of connecting with the mains again, bicycle can travel automatically.As meet the slope, can add foot-operated.If road is crowded, can cut off the electricity supply, the drive vehicle that tramps with one's feet advances.If storage battery does not have electricity, pull bar 4 can be pulled out, make driving gear 2 and ring gear 1 jump out of mesh.
