Problems solved by technology

[0002] The motor rotor, sprocket and rear drive wheel of electric bicycles currently on the market are rigidly connected, and there are two problems as follows: 1. After starting the electric bicycle motor, the motor drives the wheel to rotate, and at the same time it will drive the pedals to rotate at a high speed , the high-speed rotating pedals can easily injure the user
2. When the pedals are used alone to provide power, it is necessary to overcome the resistance from the wheels and the mutual inductance resistance generated by the motor coil. It is very laborious during use, and it is a great waste of use to overcome the mutual inductance resistance generated by the motor coil. Physical strength of the user, resulting in a bad user experience

Embodiment

[0022] Such as figure 1 As shown, a new electric bicycle transmission mechanism includes a mandrel 1, a motor, a sprocket 8 and a planetary mechanism. The motor and the planetary mechanism are all arranged on the mandrel 1, and the motor is connected to the planetary mechanism. A first clutch 7 for disconnecting and connecting the sprocket 8 and the planetary mechanism is provided.

[0023] Wherein, the planetary mechanism includes a ring gear 6 , a planetary gear 9 , and a sun gear 13 . The ring gear 6 is arranged on the spindle 1 .

[0024] In addition, the ring gear 6 is connected to the sprocket 8 , and the first clutch 7 is disposed between the ring gear 6 and the sprocket 8 .

[0025] Wherein, the planetary mechanism also includes a planet carrier 10 , the planet carrier 10 is rigidly connected with a rear wheel 11 , and the planet wheel 9 revolves around the planet carrier 10 .

[0026] In addition, the rear wheel 11 is mounted on the spindle 1 via rolling bearings. ...

Abstract

The invention relates to the field of electric bicycle, and in particular to a novel electric bicycle transmission mechanism. According to the novel electric bicycle transmission mechanism, a single stage planetary gear mechanism is installed on a transmission line of an existing electric bicycle. A motor is connected with a sun wheel of a planetary mechanism. A chain wheel is connected with a gear ring of the planetary mechanism, and a rear wheel is connected with a planetary frame of the planetary mechanism. A planetary gear mechanism has the characteristic of being provided with two degreesof freedom, so that the problem of an existing electric bicycle is solved, the advantages of a bicycle and an electric vehicle are retained, and the novel electric bicycle transmission mechanism is especially suitable for the outdoor cycling.
