Including with output shaft and rotating cylinder, the rotating cylinder both ends are respectively fixed with the gear driven gear and use for being engaged with tumbler gear
In the two gear driven gears engaged with two gear driving gear, the rotating cylinder is internally provided with axis hole, and middle part secures unidirectionally in axis hole
Device, axis hole is interior to secure bearing positioned at isolator both ends, and the rotating cylinder is fixedly connected by isolator, bearing with output shaft.
The operation principle of this base case is：In the gearbox of battery-operated motor cycle, it can be used mechanism as output machine
Output shaft is rotatably installed on the babinet of gearbox by structure, and one end of output shaft passes through the wheel of gear box and motor
It is fixed.One gear driven gear is engaged with tumbler gear, two gear driven gears are engaged with two gear driving gear.
Mechanism can drive a gear driven gear to rotate in use, keeping off driving gear and tumbler gear by one, can also lead to
It crosses two gear driving gear and drives two gear driven gear rotations, can adjust as needed, to drive output shaft to rotate, make electronic rub
The wheel of motorcycle rotates so that battery-operated motor cycle has certain speed.When motor stops, output shaft wheel inertia
It continues to rotate under effect, since rotating cylinder is fixedly connected by isolator, bearing with output shaft, under the action of isolator,
Output shaft rotation rotating cylinder can't rotate therewith so that a gear driven gear or two gear driven gears will not be by speed changers
Structure drive motor rotation, to avoid the structure in motor and speed changer from forming resistance to the forward of battery-operated motor cycle,
Effectively reduce the waste of the energy.Mechanism one keeps off driven gear simultaneously and two gear driven gears are wholely set, and installation makes its dress
With simplification, and rotating cylinder is rotated when operation, makes operating steadily for output shaft, to make the traveling of battery-operated motor cycle balance.
The advantageous effect of this base case is：Mechanism is by isolator and bearing, energy when realizing the rotation of bidentate mechanism
Output shaft rotation is enough driven, and the rotation of bidentate mechanism will not rotate when output shaft rotation, to avoid electric motorcycle wheel
Inertia reversely drives structure in speed changer to run, and on the one hand avoids energy dissipation, on the other hand effectively reduces in speed changer
Structural damage.Mechanism is made by the setting of rotating cylinder in a gear driven gear and two gear driven gear assembly, it is only necessary to
Assembly is primary, and its isolator is public, simple in structure, and assembly is easy, operates steadily.Compared with prior art, mechanism structure
Simply, it operates steadily, energy dissipation will not be caused in use.
Preferred embodiment one：As the preferred of basic scheme, the gear driven gear, two gear driven gears and rotating cylinder one
Molding.Mechanism can be made more secured, operation is more steady, and performance is more preferably.
Preferred embodiment two：As the preferred of basic scheme, isolator is internally provided with spline, and output shaft is equipped with spline fitted
Keyway.By the cooperation of spline and keyway, isolator may make to be connected with the more firm axial restraint of output shaft.
Preferred embodiment three：As the preferred of basic scheme, a gear driven gear and two gear driven gear diameters are identical.So that
It is more steady during drum rotation, to keep the operation of battery-operated motor cycle more steady.
Preferred embodiment four：As the preferred of basic scheme, the axis hole both ends are equipped with snap ring.On the one hand it can make bearing firmly
It is fixed in axis hole, on the other hand can prevent isolator, bearing from being loosened using process.
Description of the drawings
Fig. 1 is structural schematic diagram of the utility model battery-operated motor cycle speed change with unidirectional bidentate mechanism embodiment.
Specific implementation mode
The utility model is described in further detail below by specific implementation mode：
Reference numeral in Figure of description includes：Output shaft 10, keyway 11, rotating cylinder 20, axis hole 21, one keep off driven gear
30, two gear driven gears 31, isolator 40, spline 44, bearing 50, snap ring 51.
As shown in Figure 1, the unidirectional bidentate mechanism of battery-operated motor cycle speed change, including with output shaft 10 and rotating cylinder 20, rotating cylinder 20
Both ends are respectively fixed with the gear driven gear 30 for being engaged with tumbler gear and two for being engaged with two gear driving gear
Keep off driven gear 31；Rotation is more steady when in order to use, and a gear driven gear 30, two keeps off 20 one of driven gear 31 and rotating cylinder
Molding, and a gear driven gear 30 is identical with two gear 31 diameters of driven gear.The inside of rotating cylinder 20 is provided with axis hole 21, in axis hole 21
