Abstract
The utility model relates to an electric bicycle speed reducing mechanism, which is characterized in that the utility model is provided with one driving gear arranged on an inner rotor of a motor of an electric bicycle; three planetary gears are uniformly distributed on the circumference of the driving gear; the planetary gears are arranged on an overrunning clutch assembly through a short shaft; the three planetary gears are engaged with one inner ring gear; the inner ring gear is installed on a rotating hub of the electric bicycle. The driving gear can be driven after the inner rotor of the motor rotates; the planetary gears are driven by the driving gear; the inner ring gear can be driven by the planetary gears; the hub is driven by the inner ring gear; the hub is connected with wheels; thereby, a speed reducing transmission purpose can be achieved. The torque of the electric bicycle can be increased through the speed reduction of a planetary mechanism; thereby, the utility model is especially good for climbing. Because the planetary gears are connected with the overrunning clutch assembly (the overrunning clutch assembly is the same with the prior art), the utility model is good for the gliding of the electric bicycle, the energy consumption can be saved and the continued mileage can be increased.
Description
Technical field
The utility model relates to speed reduction gearing, mainly is applicable on the battery-driven car (as Electrical Bicycle, electro-tricycle, battery-operated motor cycle).
Background technology
Battery-driven car (as Electrical Bicycle) adopts slowspeed machine, and motor changes hub outside needing to drive behind speed reduction gearing.Though the existing motor that is used for Electrical Bicycle is through gear reduction, the battery-driven car moment of torsion is little, and hill climbing ability is poor; And existing applied slowspeed machine does not have power-transfer clutch, and the ability that therefore continues is also poor, and energy consumption is big.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of moment of torsion big, again the Electrical Bicycle speed reduction gearing of energy saving.
The technical scheme of the utility model Electrical Bicycle speed reduction gearing is: it is characterized in that the driving gear that has one to be installed on the electric bicycle motor internal rotor, peripheral uniform three planetary wheels of driving gear, each planetary wheel is installed on the overriding clutch assembly through minor axis, three planetary wheels are meshed with an internally toothed annulus, and internally toothed annulus is installed on the commentaries on classics hub of Electrical Bicycle.The technical program is rotated the back by the motor internal rotor and is driven driving gear, and driving gear drives planetary wheel, and planetary wheel drives internally toothed annulus, and internally toothed annulus drives wheel hub, and wheel hub is connected with wheel, reaches the deceleration transmission purpose.Moment of torsion by planetary mechanism deceleration having increased battery-driven car is particularly conducive to climbing.Because of planetary wheel is connected with overriding clutch assembly (the overriding clutch assembly is a prior art), help sliding of battery-driven car again, energy efficient increases mileages of continuation.
The utility model Electrical Bicycle speed reduction gearing, its planetary wheel are that nylon material is made, between planetary wheel and minor axis deep groove ball bearing are installed, and help rotating.In the both sides of deep groove ball bearing circlip for shaft and circlip for bore are arranged, fixing reliable.

The specific embodiment
The utility model discloses a kind of Electrical Bicycle speed reduction gearing, as shown in Figure 1 and Figure 2, its major technology is characterised in that a driving gear 7 that is installed on the electric bicycle motor internal rotor, peripheral uniform and three planetary wheels 2 that are meshed of driving gear 7, each planetary wheel 2 is installed on the overriding clutch assembly 3 through minor axis 8, three planetary wheels 2 only are meshed with an internally toothed annulus 1, and internally toothed annulus 1 is installed on the commentaries on classics hub of Electrical Bicycle.So this speed reduction gearing is one group of planetary gear speed reducing mechanism, the moment of torsion through planetary gear speed reducing mechanism increase battery-driven car helps improving hill climbing ability.While driving gear 7 adopts modification coefficient with planetary wheel 2 and with internally toothed annulus 1 when designing, make and mesh between each tooth better, increases gear life.It is made that particularly planetary wheel adopts MC oil-containing nylon material, carries lubricatedly, and performance is good, the gear life height.8 of planetary wheel 2 and minor axises are installed deep groove ball bearing 5, rotate flexibly.And circlip for shaft 4 and circlip for bore 6 are arranged in the both sides of deep groove ball bearing 5, fixing reliable.
