Technical Field
[0001] The utility model relates to the technical field of electric motorcycles, in particular to a novel motor reducer for electric motorcycles. Background Art
[0002] The electric motorcycle uses a handlebar to steer the front wheel, which allows for flexible steering and fast motor response.
[0003] In order to achieve the deceleration effect, the internal structure design of the reducer of a traditional motorcycle is very complex, which leads to a high cost of the reducer. At the same time, due to the complex internal structure, there cannot be a large gap between the reduction gears, and the gear meshing needs to be very precise, which is not conducive to manual maintenance.
[0004] Therefore, a novel electric motorcycle motor reducer is proposed. Summary of the invention
[0005] The purpose of the utility model is to provide a novel electric motorcycle motor reducer to solve the problems raised in the above background technology.
[0006] To achieve the above object, the utility model provides the following technical solutions: a novel electric motorcycle motor reducer, comprising a driving motor, a transmission shaft is installed on the driving motor, and a transmission gear is installed on the outer side of the transmission shaft;
[0007] The driving motor is provided with a front end cover, an output shaft is provided on the front end cover, an output gear is provided on the outer side of the output shaft, and the output gear is meshed and connected with the transmission gear.
[0008] Preferably, a secondary bearing is installed on the front end cover, and the output shaft is rotatably connected to the front end cover via the secondary bearing.
[0009] Preferably: a reducer housing for limiting and protecting is installed on the front end cover.
[0010] Preferably, one end of the output shaft passes through the reducer housing and is provided with a pulley.
[0011] Preferably, a main bearing is installed on the reducer housing, and the transmission shaft is rotatably connected to the reducer housing through the main bearing.
[0012] Preferably, the diameter of the transmission gear is smaller than the diameter of the output gear.
[0013] Compared with the prior art, the utility model has the following beneficial effects: the output gear is driven to rotate by the transmission gear and the transmission gear diameter is smaller than the output gear diameter, so that the single-stage reduction capability can be achieved. The main bearing and the auxiliary bearing are half-wrapped by the outer convex shape of the reducer housing, which can effectively limit the positions of the two bearings, thereby ensuring the close fit between the transmission gear and the output gear, and also facilitating disassembly and maintenance.
