Mid-motor having reverse braking function and installed on common bicycle

Abstract

The invention discloses a mid-motor installed on a common bicycle. The mid-motor comprises a motor case fixed on a bottom bracket of a frame. A magnet ring is fixedly connected to a bicycle axle. A hall sensor corresponding to the magnet ring is fixed to the outer side of the motor case. A motor shaft, a core component, an inner ring II, a ball II, a shift rack II, a controller and a sucker are disposed in the motor case, wherein the motor shaft is in drive connection with an outer ring of the bicycle, the core component surrounds the motor shaft, the inner ring II in clearance fit with the core component is fixedly sleeved outside the motor shaft and located between the core component and the motor shaft, the ball II is disposed between the core component and the inner ring II in a rolling manner, the shift rack II is capable of moving the ball II, both the hall sensor and the core component are electrically connected with the controller, and the sucker with an inner coil and electrically connected with the controller is used for sucking the shift rack II and adjusting the shift rack II. The bicycle mid-motor has the function of reversely braking the bicycle.

Description

technical field [0001] The invention relates to a driving device of a bicycle, in particular to a middle motor installed on an ordinary bicycle. Background technique [0002] At present, the middle motor installed on the ordinary bicycle does not have a reverse brake function, that is to say, when the motor runs to drive the bicycle to advance, the rider can not power off the motor by stepping on the bicycle pedal backwards. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a mid-mounted motor applied to ordinary bicycles with a reverse brake function. [0004] The technical solution of the present invention is: a central motor installed on an ordinary bicycle with a reverse brake function, comprising: a central shaft pierced in the bottom bracket tube of the bicycle frame, and a central shaft fixedly sleeved outside the central shaft. Inner ring Ⅰ, an outer ring that surrounds the inner ring Ⅰ and has a gap...
