Problems solved by technology

The structure of this one-piece flywheel is unreasonable, the coaxiality of the ratchet and the pawl cannot be adjusted, there are many production costs, and the replacement of the flywheel is not convenient enough. After the flywheel is installed, it is easy to cause problems such as flywheel deviation and jamming.

Embodiment Construction

[0026] Figure 1 to Figure 5 It shows a specific embodiment of the split-type flywheel rear drive motor for electric bicycles of this application, which mainly includes a main shaft 1, a hub shell 2, a ratchet 4, a sleeve 5, a flywheel chainring 6 and a pawl 7, etc. part. in:

[0027] In actual application, the main shaft 1 is horizontally fixed on the rear frame of the electric bicycle. The hub shell 2 is composed of a screw-connected shell body and an end cover (not marked in the figure), and the hub shell 2 is rotatably mounted outside the main shaft 1 through a bearing. The ratchet 4 is detachably fixed on the hub shell 2 by screws, and the ratchet 4 is arranged coaxially with the main shaft 1 . The sleeve 5 is coaxially movably sleeved on the outside of the main shaft 1 . The flywheel toothed disc 6 is coaxially fixed on the sleeve 5, and the flywheel toothed disc 6 and the sleeve 5 may be of an integrated structure or may be of a separate structure. In this embodimen...

Abstract

The application of the invention discloses a split type free wheel real-wheel driving motor for an electric bicycle. The split type free wheel real-wheel driving motor comprises a main shaft which is horizontally arranged, and a hub housing which is rotatably mounted outside the main shaft. The split type free wheel real-wheel driving motor further comprises a ratchet wheel which is fixed on the hub housing in a dismountable manner, a sleeve which is movably arranged on the main shaft in a sleeving manner, and a free wheel fluted disc which is fixed on the sleeve, wherein a ratchet which is connected with the ratchet wheel is arranged on the sleeve; and the ratchet and the ratchet wheel are matched to form a ratchet wheel-ratchet one-way clutch, and are connected in a dismountable manner. According to the split type free wheel real-wheel driving motor disclosed by the invention, the structure is ingenious, and the coaxiality of the ratchet wheel on the main shaft and the coaxiality of the ratchet on the main shaft can be separately adjusted when the motor is assembled, so that problem that the motor is deflected and stuck can be solved.

Description

technical field [0001] The present application relates to the field of electric bicycles, in particular to a split flywheel rear drive motor for electric bicycles. Background technique [0002] At present, an integrated flywheel structure is usually installed on the rear drive motor of an electric bicycle. The integrated flywheel mainly includes a ratchet pawl one-way clutch and a flywheel tooth plate integrally arranged on the ratchet pawl one-way clutch, and the ratchet pawl one-way clutch The ratchet assembly and pawl assembly on the clutch are non-detachable integral structures. The structure of this one-piece flywheel is unreasonable, and the coaxiality of the ratchet and the pawl cannot be adjusted. There are many production costs, and the replacement of the flywheel is not convenient enough. After the flywheel is installed, it is easy to cause problems such as flywheel deviation and jamming. Contents of the invention [0003] The purpose of this application is: to ...
