The invention discloses a driving wheel mechanism treading force sensing device which comprises a driving wheel mechanism installed on a motor shaft on the outer side of an end cover of a hub motor and a torque sensing assembly arranged in the driving wheel mechanism, the driving wheel mechanism comprises a driving wheel installation sleeve, and at least one driving wheel is fixed to the outer portion of the driving wheel installation sleeve. The transmission wheel is used for being connected and fixed to an output wheel on a center shaft of the electric bicycle through a flexible traction piece, and pedals are fixed to the two ends of the center shaft through cranks. The torque sensing device is characterized in that the torque sensing assembly comprises a deformation shaft sleeve arranged on the motor shaft, a strain gauge is attached to the deformation shaft sleeve, and the inner circumference of the transmission wheel installation sleeve makes contact with the outer circumference of the deformation shaft sleeve through a plurality of bearings so that the radial component force, transmitted to the transmission wheel installation sleeve, of the middle shaft treading force can be transmitted to the deformation shaft sleeve. The pedal force sensing device of the driving wheel mechanism is higher in torque signal acquisition precision, simple in structure and easy to assemble.

    本发明公开了一种传动轮机构踏力传感装置,包括装于轮毂电机的端盖外侧电机轴上的传动轮机构及设置其中的力矩传感组件,传动轮机构包括传动轮安装套筒,传动轮安装套筒外部固定有至少一传动轮,传动轮用于经柔性牵引件连接固定于电动自行车中轴上的输出轮,中轴两端经曲柄固定脚踏;其特征在于:力矩传感组件包括一套设于电机轴上的变形轴套,变形轴套上贴附有应变片,而传动轮安装套筒内周经由若干轴承与变形轴套外周接触,用以将传递至传动轮安装套筒上的中轴踏力的径向分力传递至变形轴套上。本发明提供的这种传动轮机构踏力传感装置不仅力矩信号采集精度更高,且结构简单,易于装配。
