Abstract

The invention discloses a torque sensing device used for a moped transmission system. The torque sensing device comprises a shifting lever, a small gear, an elastic part and a Hall element. The shifting lever comprises a mounting part, a tip part connected with one end of the mounting part and a set of teeth connected with the other end of the mounting part, wherein a rotary shaft is sleeved with the shifting lever through the mounting part, and the shifting lever is engaged with the small gear through the set of teeth; one end of the elastic part is connected with the tip part, and the other end of the elastic part is connected with a box; a magnetic pole is arranged on the small gear; and the Hall element is mounted on the box and is arranged above the magnetic pole. The design structure and principle are simple, cost is low, treading torque of a pedal can be monitored, and thus output of a central system can be adjusted according to treading force. Accordingly, assistance can be provided more comprehensively and flexibly by combining speed monitoring. The moped transmission system is further disclosed, torque of a pedal main shaft can be transferred to the rotary shaft, and normal rotation of the pedal main shaft is not influenced.

Description

technical field [0001] The invention relates to the technical field of the power-assisted vehicle transmission system, in particular to a torque sensing device used in the power-assisted vehicle transmission system. Background technique [0002] At present, most electric power-assisted bicycles on the market control the output of the central system by detecting the speed when riding. Specifically, they provide high output when the speed is high and low output when the speed is low. This control method has the following problems : When encountering an uphill, headwind, or rough road, the cyclist needs the system to provide greater assistance, but the system provides lower assistance due to the low speed; when the vehicle speed is fast when going downhill, but the general cyclist does not need assistance, the system instead will provide greater assistance. Although a small number of models can adjust the output of the system according to the torque of the pedals during riding...
