Problems solved by technology

[0003] However, this technical improvement is more dependent on the improvement of materials, and cannot actually solve the problem of unreasonable design of the transmission structure, that is, the transmission mechanism with the planetary gear as the main body is subject to a large impact when the clutch is engaged during the transmission. Affect the riding experience and the service life of the internal gear hub

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] like figure 1 As shown, the present invention provides an auxiliary power bicycle speed change control device with a rotating inner hub, which includes a rotating inner gear hub (SHIMANOSG-8R36), which is set on the rotating inner hub gear rotation mechanism A magnet 2 at one end, and an induction mechanism 3 for sensing the position of the magnet 2 is provided at a position corresponding to the magnet 2. The induction mechanism 3 can sense the movement of the magnetic steel 2, record and transmit the pulse signal of the magnetic steel 2 movement, and the motor of the auxiliary power bicycl...

Abstract

The invention discloses an auxiliary-power-bicycle speed change control device with a rotating inner hub and a control method. The auxiliary-power-bicycle speed change control device comprises magnetic steel and an induction mechanism. The magnetic steel is arranged at one end of a rotating mechanism. The induction mechanism used for inducting the position of the magnetic steel is arranged at a position corresponding to the magnetic steel. A motor of an auxiliary power bicycle adjusts an output current according to pulse signals outputted by the induction mechanism, the output current is reduced during speed changing and gear shifting, and the output current reverts to a normal value during normal constant-speed travelling, so that stable and smooth speed change is realized, riding experiment is improved, and service life of the inner speed-changing hub is prolonged.

Description

technical field [0001] The invention relates to the field of auxiliary power bicycle manufacturing, in particular to a speed change control device for an auxiliary power bicycle with a rotating inner hub, and a method for controlling the speed change of an auxiliary power bicycle by using the control device. Background technique [0002] There are two types of bicycle transmissions: external transmissions and internal transmissions. Although the structure of the external transmission is simple, its shifting action is unstable and its life is short. The internal transmission mainly uses a closed planetary gear train as the main body of the transmission. It has a compact structure and is usually installed in the rear. On the wheel hub, the action is reliable and the service life is long. However, in actual use, it is found that when the internal transmission is used on an auxiliary power bicycle, since the motor continues to output power during the speed change, when riding, s...
