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

The automobile-used shift motor gearbox designs of a kind of electrical salf-walking
Technical field
The present invention relates to a kind of gearbox designs, the automobile-used shift motor gearbox designs of especially a kind of electrical salf-walking.
Background technique
The shift motor that conventional electric bicycle is installed, its gearbox designs can only adopt grease lubrication, but because grease is solid-state, motor is in rotation process, engaged gears can squeeze out occlusal surface grease, and after running a period of time, gear can not get sufficient lubrication, thus cause gear wear, cause that noise is large, high, the gear life of consuming energy reduces greatly; In addition, after motor works long hours, grease can slowly reduce, and user cannot annotate voluntarily, and finally because grease is exhausted, cause performance degradation, parts damages speed is accelerated.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcome in background technique, there is provided a kind of electrical salf-walking automobile-used shift motor gearbox designs, this gearbox designs, thin oil is adopted to splash interchangeable lubricating system, solve the problem causing parts Fast Wearing because of oil disappearance, component life is multiplied.
For solving the problem, the present invention takes following technological scheme:
The automobile-used shift motor gearbox designs of a kind of electrical salf-walking of the present invention, comprise motor room and gearbox, described motor room and gearbox are separated by housing, in described motor room, live axle is installed, gearbox is stretched in one end of described live axle, be provided with output shaft in described gearbox, one end of described output shaft extend out to the outside of gear shift cover.Described live axle forms rotatable cooperation by motor room's bearing and housing, and described output shaft forms rotatable cooperation by gearbox bearing and gear shift cover; The cooperation place of described live axle and housing is provided with oil sealing, described in state output shaft and gear shift cover cooperation place oil sealing is installed; The top of described gearbox is provided with oil filler, and the bottom of described gearbox is provided with fuel outlet, and the top of described gearbox is provided with labyrinth.
The automobile-used shift motor gearbox designs of a kind of electrical salf-walking of the present invention, due to motor room is separated with gearbox, at motor indoor location live axle, gearbox is stretched in one end of described live axle, in gearbox, output shaft is installed, one end of described output shaft extend out to the outside of gear shift cover, live axle by driving gear by transmission of power to output shaft, described live axle forms rotatable cooperation by motor room's bearing and housing, described output shaft forms rotatable cooperation by gearbox bearing and gear shift cover, the cooperation place of described live axle and housing is provided with oil sealing, the described cooperation place stating output shaft and gear shift cover is provided with oil sealing, and the top of gearbox is provided with oil filler and labyrinth, fuel outlet is provided with bottom gearbox.Therefore, the automobile-used shift motor gearbox designs of a kind of electrical salf-walking of the present invention, thin oil can be adopted to splash interchangeable lubricating system, liquid lubricant is filled in gearbox, driving gear is immersed in oil for a long time, and the effect of ventilative decompression can be played in labyrinth, and user can according to service manual requirement, carry out intermittent oiling and maintenance of draining the oil, the invention solves the problem causing parts Fast Wearing because of oil disappearance, component life is multiplied, also there is low cost of manufacture, the advantage such as easy for installation.
