Technical field

The utility model relates to a kind of improved Electrical Bicycle actuating device, this improved Electrical Bicycle actuating device is when running into fault or wearing and tearing, can simple and easyly fast actuating device and unidirectional transmission be split into independent individual, detected the dismounting and change spare and accessory parts respectively, make and reduce maintenance time and cost, avoid whole group to change.

Background technology

Have leisure function because Electrical Bicycle removes, necessary fashion can be the vehicle of riding instead of walk, and can not make problems such as waste gas and noise pollution, and therefore along with the storage battery development of technology, the use of Electrical Bicycle and sales volume increase progressively day by day; Yet the actuating device of commonly using Electrical Bicycle then is to be fixed on the Vee formation hack lever, and be arranged at the both sides of wheel hub respectively with the flywheel that chain drives, utilize Direct Current Motor to drive big small umbrella gear and produce deceleration transmission, again with unidirectional transmission body driven wheel hub rotation, make do not change and shadow to trampling function, and can reach manpower and the dual-purpose effect of electric power, but this unidirectional drive sleeve body is positioned at actuating device, and whole one-tenth seal construction, when running into fault or wearing and tearing, field-strip is inconvenience very, often must change the actuating device of whole group, cause cost quite high, it is necessary to be improved so have.

Summary of the invention

Main purpose of the present utility model is exactly the defective that overcomes above-mentioned prior art, promptly be at commonly using the Electrical Bicycle actuating device, inconvenience in assembling and maintenance and time-consuming, and studied improvement, and a kind of improved Electrical Bicycle actuating device is provided, it can make when running into fault or wearing and tearing, can simple and easyly fast actuating device and unidirectional transmission be split into independent individual, detected the dismounting and change spare and accessory parts respectively, make and reduce maintenance time and cost, avoid whole group to change.

The purpose of this utility model realizes by following technical proposals, improved Electrical Bicycle actuating device provided by the utility model is a side that unidirectional transmission directly is cemented in wheel hub of electric bicycle, and be fixedly arranged on the both sides of wheel hub respectively with the flywheel that drives with pedal chain, unidirectional transmission also forms interlocking with one with the actuating device of rotational speed governor modulation rotating speed, this actuating device is for to be fixedly arranged on the Electrical Bicycle frame via one, can produce the motor of high speed revolution with the D.C power supply, on its output shaft, be installed with a transmission gear, around the transmission gear and bridle joint have number form to become the pinion gear of deceleration effort, mesh large umbrella gear in rotating disk leading section with bevel pinion again for the pinion gear socket, to form the switching of orthogonal formula, and then impel the wheel hub rotation with the unidirectional transmission that large umbrella gear drives interlocking, cause wheel revolutions to advance, and when fault or wearing and tearing are arranged, can simple and easyly fast actuating device and unidirectional transmission be split into independent individual, detected the dismounting and change spare and accessory parts respectively, make and reduce maintenance time and cost, avoid whole group to change.

The technology that relevant the utility model adopted, means and effect thereof are lifted after a preferred embodiment and conjunction with figs. be described in more detail in now, believe the above-mentioned purpose of the utility model, structure and feature, can be goed deep into and concrete understanding.

Description of reference numerals: 1 vehicle frame; 2 storage battery devices; 3 actuating devices; 5 rotational speed governors; 8 unidirectional transmissions; 16 pedals; 17 chains; 30 output shafts; 31 motors; 32 connecting supports; 33 large bevel gears; 34 permanent seats; 35 bearings; 41 wheel hubs; 42 flywheels; 43 axostylus axostyles; 81,82 ring bodies; 300 transmission gears; 301 pinion gears; 303 rotating disks; 304 axostylus axostyles; 311 small bevel gears; 340 screws.

The specific embodiment

Please cooperate and consult shown in the accompanying drawing, the utility model is combined by storage battery device 2, rotational speed governor 5, actuating device 3 and unidirectional transmission 8; Wherein storage battery device 2 is for being fixedly arranged on the vehicle frame 1, can rotational speed governor 5 modulation in addition, the D.C power supply that is produced, for making motor 31 produce high speed revolution earlier, then promote to be installed with the actuating device 3 on the Electrical Bicycle frame, on its motor 31 output shafts 30, be installed with a transmission gear 300, around the transmission gear 300 and bridle joint the pinion gears 301 of number for deceleration efforts are arranged, then be provided with on the rotating disk 303 and protrude out axostylus axostyle 304 for pinion gear 301 sockets, the place then is provided with a bevel pinion 311 in rotating disk 303 other end axle center, bevel pinion 311 peripheries then are formed with connecting support 32, and be meshing with each other in the annular groove 321 of connecting support 32 with another large bevel gear 33, large bevel gear 33 in addition side then with a permanent seat 34 fitted bearings 35, utilize screw 340 to be locked on the connecting support 32, again with inside and

outside ring body

82,81 constitute the unidirectional transmission 8 that the unidirectional revotating card of tool ends effect, direct wheel hub 41 1 sides of locking outside Electrical Bicycle axostylus axostyle 43 then, make with pedal 16, the flywheel 42 that chain 17 drives is fixedly arranged on the both sides of wheel hub 41 respectively, and form interlocking with the large bevel gear 33 of actuating device 3, and drive shaft rod 43 and run through large bevel gear 33 and connecting support 32 is fixedly arranged on the vehicle frame.

During actual the use, when Electrical Bicycle is switched to automatic running, and with rotational speed governor 5 modulations, supply the D.C electric currents to motor 31 with storage battery device 2, the rotating speed of control motor 31, impel output shaft 30 to produce high speed revolution, the pinion gear 301 of bridle joint rotates and drive on every side with the transmission gear on it 300, and then drive rotating disk 303 and slowed down and increase the mode of torsion and produce and circle round, and with external large bevel gear 33 rotations of bevel pinion 311 drives of leading section, power is through turning to and then cause the unidirectional transmission of rabbeting with other side of large umbrella gear 8 because of inside and

outside ring body

82,81 turns become mutually only to block, and then drive wheel hub 41 impels wheel revolutions to advance; And when Electrical Bicycle switched to foot-operated the driving, when with foot pedals 16 conduction chains 17, impel flywheel 42 to drive wheel hub 41, cause wheel revolutions to advance, though unidirectional transmission 8 is locked in wheel hub 41 opposite sides and since opposite inside and

outside ring body

82,81 turns of transmission trend reverse escape, therefore can form idling conditions, drive large bevel gear 33 turns and can not draw, cause and to reach with foot-powered effect.

Because unidirectional transmission 8 is locking sides at Electrical Bicycle hub 41, and form interlocking with the large bevel gear 33 of actuating device 3, cause actuating device 3 and can be assembled into one in advance, and then interlocking is to the outside of unidirectional transmission 8, it is convenient not only to assemble, when maintenance, dismounting actuating device 3 is also very convenient, during failure wear, also is easy to be changed with regard to spare and accessory parts, cause the reduction maintenance cost, the effectiveness of avoiding whole group to change.

In sum; above for only being part embodiment of the present utility model; but be not in order to restriction the utility model, cause variation a little or the modification made according to intention spirit of the present utility model and feature, then should be included within this novel claimed claim.
