Abstract

The invention discloses a central system based on wireless torque detection. The system comprises a first shell, an intermediate shaft, a crankset and a second shell, wherein the intermediate shaft penetrates through the first shell, the crankset is fixed to the intermediate shaft through a clutch, the second shell is fixedly connected with the first shell, the first shell comprises a torsion barrel, a torque transducer and a first clutch, the torsion barrel is arranged on the intermediate shaft in a sleeved mode, and one end of the torsion barrel is fixedly connected to the first clutch; the torque transducer is fixed to the torsion barrel, and when the intermediate shaft is stressed, the torque is transmitted in the sequence of a left / right side pedal-the intermediate shaft-the torsion barrel-the first clutch-the crankset. The system can achieve zero starting, and the riding effect is outstanding; the system adapts to all road conditions, better assistance effect can be obtained on both low-speed riding and high-speed riding, the system has the advantages of being convenient to install and maintain, stable in work and the like, and the real relax riding purpose can be achieved for a user.

Description

technical field

[0001] The invention relates to the technical field of power-assisted bicycle drive, in particular to a mid-mounted system based on wireless torque detection that can realize zero start. Background technique

[0002] Power-assisted bicycles, also known as power-assisted electric bicycles, are a riding tool between bicycles and electric vehicles. They provide the kinetic energy needed for bicycles through electric power to assist manpower. The product of an environmentally friendly lifestyle. The central system is the core component of the power-assisted bicycle, which integrates torque detection, controller, and motor drive to control the normal driving of the vehicle.

[0003] At present, power-assisted bicycles are more popular in foreign markets, such as Germany, Japan and other relatively developed countries. In my country, electric bicycles still occupy the main market, and most electric bicycles are driven by wheel hubs, which have obvious disadvantag...
