Wheel hub structure 【0001】

This creation relates to a vehicle wheel hub structure, especially a design through a hub, a fixed shaft, an internal rotary DC motor and a stepless transmission.

According to the issue of energy conservation and carbon reduction in recent years, more and more people are discussing. In addition to reducing carbon dioxide emissions to protect the earth and reducing dependence on oil, many people have begun to replace bicycles by walking or walking. Car or ride locomotive.

[0003]

At present, most of the bicycles use the pedaling method to let the chain drive the gears to rotate, so that the wheels can rotate forward in the direction of the gears. However, because of the gradual development of cycling in recent years, To achieve the efficiency of riding and saving, some manufacturers have designed electric bicycles with automatic shifting to allow consumers to choose.

[0004]

However, most of the existing electric vehicles with automatic shifting use an externally-rotating motor to provide electric power, and the externally-rotated motor has the disadvantage that a large current needs to be output at the start to change the wheel frame from a stationary state to a rotating state, and The automatic shifting mode is driven by the externally-rotating motor to rotate the shifting gear so that the wheel frame can be rotated forward. However, because of the shifting relationship, the externally-rotating motor and the shifting are easily caused when a large current is output. Damage to the gears, which in turn reduces the overall service life.

[0005]

In addition, the conventional automatic transmission electric vehicle or the transmission gear mechanism is provided, but the mechanism is mostly implemented by combining fixed gears, and the motor output is limited by the existing gear ratio, and the motor cannot be automatically adjusted according to the driving road condition. Azimuth torque output, after long-term operation, it is easy to cause excessive overload of the motor mechanism components. The conventional automatic transmission electric vehicle is faulty or the parts must be replaced frequently, and the convenience and efficiency of the intended use of the electric vehicle cannot be achieved.
