Manual shift brushless large hub motor

Abstract

The invention relates to a manual gear-shifting brushless large-hub motor. The manual gear-shifting brushless large-hub motor is composed of a half axle type hub wheel, a rear wheel bracket, an outer rotor brushless motor, a flywheel transmission, an axle clutch, a manual rotation handle and a controller; the inner left end of the hub of the half axle type hub wheel is provided with the outer rotor brushless motor; the right end of the hub of the half axle type hub wheel is provided with the flywheel transmission; the axle clutch can fully utilize the space of the left half shaft of the half axle type hub wheel, so that the axial dimension of the half axle type hub wheel can be decreased; the gear-shifting mode of the manual rotation handle is simple and effective; when the rotation handle is tightened, a high-speed gear is enabled, the outer rotor brushless motor performs direct driving and has an anti-charging flexible braking function; when the rotation handle is relaxed, a low-speed gear is enabled, slope-climbing driving is more powerful after gear speed reduction; and the idle resistance of the motor is very small, so that an electric car can be ridden easily like a bicycle when having no electricity. With the manual gear-shifting brushless large-hub motor adopted, problems in gear speed variation and gear shifting of a current hub motor can be solved, and troubles caused by the uncontrollability of the driving of the clutch of the current hub motor can be eliminated.

Description

technical field [0001] The invention relates to an electric wheel hub motor, to be precise, a manual gear-shifting brushless large wheel hub motor. Background technique [0002] At present, in the whole country, most of the motors used by various electric vehicles on the road are brushless and toothless large hub motors. It has become the current Mainstream products in the market. But it is not perfect. First of all, it does not have a high-speed and low-speed transmission, and it cannot take into account both high-speed driving and low-speed climbing. The ride is pretty heavy. There is a patent with the application number: "2007200020424" and the name is: "Two-speed electric wheel hub motor using forward and reverse speed change of the motor". The self-locking one can only rotate forward, but not reversely, and the electric vehicle cannot reverse, which affects normal use, and the structure is complicated and the cost is high.

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the existing brushless and toothless large hub motors, the present invention introduces a manual shifting brushless large hub motor. The anti-charging flexible braking function of the large-toothed hub motor also overcomes the contradiction that the hub motor can only rotate forward and cannot reverse, and it can be easily ridden like a bicycle when the electric vehicle is out of power
