Description
Technical field
The utility model relates to Mould Machining field, particularly relates to a kind of electric bicycle driver.
Background technology
At present, domestic main Electrical Bicycle production firm, all uses lead-acid battery, and DC machine is rearmounted, pure driven by power, its main shortcoming be exactly battery seriously polluted, post-processed is difficult, contaminated environment; Secondly because direct-drive type drives, make the operating mode of motor very poor; Last shortcoming carries heaviness exactly.
Till now, no matter be home market, or world market, the Electrical Bicycle used almost all adopts lead-acid battery as propulsion source, motor adopts rear-mounted installation, and ubiquitous problem is that this Electrical Bicycle is heavy, removes very inconvenient; Battery seriously polluted, recovery and the subsequent treatment of refuse battery bother very much, endanger environment greatly.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of Moped Scooter of sports type and the electric bicycle driver of the Moped Scooter of type of riding instead of walk.
A kind of electric bicycle driver of the present utility model, it comprises harmonic speed reducer, axle drive shaft, housing, the motor be socketed in housing; Described axle drive shaft is horizontally installed on harmonic speed reducer inside and is positioned at housing; Described harmonic speed reducer comprises wave producer, just wheel and flexbile gear; Described harmonic speed reducer is connected with axle drive shaft by wave producer, described flexbile gear is located at the outer ring of described wave producer by bearing, described firm wheel is fixed at described housing inner ring and is positioned at the outer ring of described flexbile gear one end, and described flexbile gear is provided with flexbile gear axle sleeve with the cooperation place of just taking turns; The outer wall of described firm wheel and the inwall of housing are fitted and are provided with radiating groove; Described firm wheel outer wall is provided with temperature sense warning device.
As preferably, described wave producer laterally extension set connects on the driving shaft and is connected with motor.
As preferably, described axle drive shaft both sides are respectively arranged with foot-operated.
As preferably, described radiating groove is built-in with filtering net.
As preferably, described electric bicycle driver also comprises silencer mechanism; Described silencer mechanism is arranged on and coordinates with flexbile gear axle sleeve and to be arranged on the side of housing.
Compared with prior art the beneficial effects of the utility model are: a kind of electric bicycle driver of the present utility model, its by harmonic speed reducer and DC micromotor integrated, be placed on the axis of boosted vehicle, utilize the large output torque of the deceleration of harmonic wave, DC machine, reach the in-use performance requirement of Moped Scooter.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of a kind of electric bicycle driver of the present utility model.
Wherein, 1, housing; 2, motor; 3, wave producer; 4, foot-operated; 5, flexbile gear; 6, just take turns; 7, flexbile gear axle sleeve; 8, temperature sense warning device; 9, radiating groove; 91, filtering net; 10, silencer mechanism; 11, axle drive shaft.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
A kind of electric bicycle driver of the present utility model as shown in Figure 1, it comprises harmonic speed reducer (not identifying in figure), axle drive shaft 11, housing 1, the motor 2 be socketed in housing 1; Described axle drive shaft 11 is horizontally installed on harmonic speed reducer (not identifying in figure) inside and is positioned at housing 1; Described harmonic speed reducer (not identifying in figure) comprises wave producer 3, just wheel 6 and flexbile gear 5; Described harmonic speed reducer (not identifying in figure) is connected with axle drive shaft 11 by wave producer 3, described flexbile gear 5 is located at the outer ring of described wave producer 3 by bearing, described firm wheel 6 is fixed at described housing 1 inner ring and is positioned at the outer ring of described flexbile gear 5 one end, and described flexbile gear 5 is provided with flexbile gear axle sleeve 7 with the cooperation place of just taking turns 6; The outer wall of described firm wheel 6 and the inwall of housing 1 are fitted and are provided with the radiating groove 9 of oblique design, described radiating groove 9 annular to be arranged on housing 1 and it is through, described radiating groove 9 is built-in with the filtering net 91 preventing extraneous foreign matter from entering housing 1 inside; Described firm wheel 6 outer wall is provided with temperature sense warning device 8; Described electric bicycle driver also comprises silencer mechanism 10; Described silencer mechanism 10 is arranged on and coordinates with flexbile gear axle sleeve 7 and to be arranged on the side of housing 1, greatly reduces noise when harmonic speed reducer (not identifying in figure) high-speed operation like this.
Above-mentioned a kind of electric bicycle driver, described wave producer 3 laterally extension set to be connected on axle drive shaft 11 and to be connected with motor 2.
Above-mentioned a kind of electric bicycle driver, described axle drive shaft 11 both sides are respectively arranged with foot-operated 4, and what it was arranged rides 4 can provide power resources by pedal, also can temper the health of user.
Compared with prior art the beneficial effects of the utility model are: a kind of electric bicycle driver of the present utility model, its by harmonic speed reducer and DC micromotor integrated, be placed on the axis of boosted vehicle, utilize the large output torque of the deceleration of harmonic wave, DC machine, reach the in-use performance requirement of Moped Scooter.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
