The utility model discloses a rear fork, rear fork assembly and electric motorcycle car as CN217649588U, it is through all arranging the first installation position and the second installation position that are used for installing control assembly and motor assembly on the rear fork, and then effectively improved the compactness that controller and motor in the electric motorcycle car were arranged, that is, reduced the controller and brought the complexity that the pencil was arranged when too dispersed for the motor (processes such as trend and fixed in the car of pencil), simultaneously, also will effectively reduce the length of pencil with the controller with the motor arrangement together, and then reduced the manufacturing cost of motorcycle. However, this structure drives the driven sprocket on the rear wheel only through the driving sprocket mounted on the motor, and has only one transmission ratio as a whole, resulting in insufficient output power.

Disclosure of utility model

In order to solve the problem of insufficient output power, the utility model provides an integrated power device for an electric bicycle or an electric motorcycle, which comprises the following specific technical scheme:

the integrated power device for the electric bicycle or the electric motorcycle comprises a motor, a front sprocket, a driving gear, a primary gear, a secondary gear, a middle hub and a front sprocket, wherein the driving gear is arranged on a shaft of the motor and is positioned in the driving seat, the primary gear is rotatably arranged on the driving seat and meshed with the driving gear, the secondary gear is rotatably arranged on the driving seat and meshed with the primary gear, the middle hub is arranged on the secondary gear and connected with the front sprocket, and the diameters of the driving gear, the primary gear and the secondary gear are sequentially increased.

Preferably, the transmission seat comprises a transmission base arranged on the motor and a transmission cover plate arranged on the transmission base, wherein the primary gear and the secondary gear are both rotatably arranged on the transmission base and the transmission cover plate.

Preferably, the device further comprises a primary bearing arranged between the primary gear and the transmission seat, and a secondary bearing arranged between the secondary gear and the transmission seat.

Preferably, the device further comprises an oil seal arranged between the middle hub and the transmission seat.

Compared with the prior art, the utility model has the following beneficial effects:

The integrated power device for the electric bicycle or the electric motorcycle has the advantages that the multi-stage transmission ratio is realized, the output torque is greatly improved, the power is ensured, the motor is not arranged on the rear fork, and meanwhile, the integrated structure is convenient to install and compact in structure.
