Dual drive high-speed brushless hub motor of remote control gear clutch

Abstract

The invention discloses a dual drive high-speed brushless hub motor of remote control gear clutch, the top circle of the hub wheel aluminum alloy hub ring is the tire while the inner circle is provided with an umbrella type gear ring, the diameter position of the umbrella type gear ring is provided with an upper brushless motor and a lower brushless motor, the upper and lower umbrella type gears of the motor shaft are engaged at the circumference diameter point of intersection of the umbrella type gear ring, the upper brushless motor and the lower brushless motor are symmetrically mounted at the middle of the upper and the lower end of a sliding square tube shelf, the hub shaft is the bridge shelf type hub shaft symmetrically mounted on the straight line and composed of a left semi shaft, a right semi shaft, a left and right rhombus bracket and the front and rear guide connection shaft, the sliding square tube shelf is mounted on the front and rear guide connection shaft, the rotary handle is rotated by the hands for pulling the steel wire rope for remote controlling the sliding square tube shelf for sliding between the left side and the right side, the upper and lower umbrella type gears can be engaged with the umbrella type gear ring or separated. The contradiction caused by the uncontrollable drive clutch of the hub motor can be effectively solved, the sliding function and the reverse charge function can be unified perfectly, and the idle resistance of the hub motor is less than that of the hub motor provided with the overrun clutch, the electric vehicle can be rode as the bicycle while having no power.

Description

technical field [0001] The invention relates to a wheel hub motor of a light-duty electric bicycle, specifically, a remote-controlled gear clutch dual-drive high-speed brushless large hub motor. Background technique [0002] Currently on the market, the hub motor used in light electric bicycles is generally a miniature hub motor. Its main disadvantages are that the ratio of planetary gear reduction is not large enough, the efficiency of the motor is not high enough, the small sun gear is easy to wear, and the life of the motor is not long enough. , so there is still a lot of room for improvement in the existing light-duty electric bicycle hub motors. For example, the application publication number is "CN103036354A", and the name is an invention patent application for "ultra-thin multi-drive high-speed and high-efficiency brushless hub motor". It discloses the structural form It is beneficial to improve the various performance indicators of the hub motor, but it has a common ...

[0002] Currently on the market, the hub motor used in light electric bicycles is generally a miniature hub motor. Its main disadvantages are that the reduction ratio of the planetary gear is not large enough, the motor efficiency is not high enough, the small sun gear is easy to wear, and the motor life is not long enough. , so there is still a lot of room for improvement in the existing light-duty electric bicycle hub motors. For example, the application publication number is "CN103036354A", and the name is an invention patent application for "ultra-thin multi-drive high-speed and high-efficiency brushless hub motor". It discloses the structural form It is beneficial to improve the various performance indicators of the hub motor, but it has a common disadvantage with the mini hub motor, that is, because of the overrunning clutch, the reverse charging and flexible braking functions of the hub motor are lost. The two functions cannot be perfectly unified, and the structure is complex and the cost is high
