Abstract

The invention provides a variable-gear motor gearbox structure of an electric bicycle. The variable-gear motor gearbox structure comprises a motor chamber and a gearbox. The motor chamber and the gearbox are separated from each other by a shell. A driving shaft is mounted in the motor chamber. One end of the driving shaft extends into the gearbox. An output shaft is mounted in the gearbox, and one end of the output shaft extends to the outer side of a gearbox cover. Oil seals are respectively mounted at a matching position of the driving shaft and the shell as well as a matching position of the output shaft and the gearbox cover. An oil filling port and an oil discharging port are arranged at the top and the bottom of the gearbox respectively. A labyrinth is arranged at the top of the gearbox. The variable-gear motor gearbox structure of the electric bicycle has the advantages that a thin-oil splashing replaceable lubrication mode can be adopted, the labyrinth can play a role in ventilation and pressure relief, the problem of quick component abrasion caused by oil shortage is solved, and service life of components is multiplied; the variable-gear motor gearbox structure is low in production cost, convenient to mount and the like.

Description

technical field [0001] The invention relates to a gearbox structure, in particular to a gearshift motor gearbox structure for an electric bicycle. Background technique [0002] The shifting motor installed in conventional electric bicycles can only be lubricated with grease, but because the grease is solid, the gears will squeeze the grease out of the occlusal surface during the rotation of the motor. After running for a period of time, the gears will not In addition, after the motor works for a long time, the grease will gradually decrease, and the user cannot refill it by himself, and finally the grease will be exhausted, resulting in Performance is severely degraded and components break down at an accelerated rate. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies in the background technology, and to provide a transmission structure of a shifting motor for electric bicycles. This transmission structure ...
