Embodiment Construction

[0035] Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

[0036] figure 1 It is a sectional view showing a transmission of the present invention in which a sprocket 130 provided with a freewheel, that is, a one-way clutch 132 is used.

[0037] figure 2 is expressed in figure 1 A cross-sectional view of a transmission in which a normal sprocket 130 is combined with a spline fitting groove formed in the joint part between the center and the freewheel. A one-way clutch 137 is attached to the driving wheel 135 so that the movement of the carrier 210 by the motor 120 is not transmitted to the sprocket 130 side.

[0038] here, in figure 1 Inside the transmission 100 shown, since the driving wheel 135 and the planet carrier 210 are combined by splines 136 , a one-way clutch 132 must be provided on the sprocket 130 .

[0039] figure 1 and figure 2 There is the following difference, that is, in fi...

Abstract

The invention provides a transmission with both an electric motor and a pedal device and a speed changing method, which are applicable to hub embedded type transmissions of electric bicycles or small-sized motorcycles and common bicycles so that the power of the electric motor or the pedal is output to a hub shell of the wheel through a speed changing device. The speed changing device comprises a sun gear, a gear ring, a quick-use rod and a speed changing control part, wherein the sun gear is engaged with each section of planet gear; and by using an external speed changing rod, the sun gear is selectively limited by a shaft; the gear ring is engaged with the planet gear and used for transmitting the power of the speed changing device after changing the speed to the hub shell; a pin of the quick-use rod is combined on a planet gear frame; and by using the external speed changing rod, the speed changing control part enables the sun gear to be selectively limited by the shaft. The gear ring and the hub shell are connected with each other through an output rod; and the power cannot be inversely input while the hub shell rotates at a higher speed larger than the speed of the gear ring.

Description

Technical field [0001] The invention involves the transmission and transmission method built in the hub built by the bicycle wheels. More specifically, it involves an electric bicycle or small motorcycle that can be applied to an electric motor, the electric motor and the transmission and the transmission and pedal devices of all pedal devices bicycles and the pedal devices.Gas change method. Background technique [0002] Usually a bicycle is a transportation of the wheels to rotate the wheels to rotate the wheels. [0003] This kind of bicycle has developed as an electric bicycle driven by electric motor -driven motor. [0004] Electric bicycles can adjust the rotation power of the motor by operating the acceleration device, which can control the speed of the bicycle from low speed to high speed. This driving method that uses the acceleration device is called a small motorcycle type. [0005] In addition, electric bicycles also have the pedal auxiliary or PAS method that can be...
