Abstract

The invention relates to an electric bicycle driving force ratio detecting device that includes testing platform body, and control cabinet. Data lines are connected to the testing platform body and the control cabinet. Road condition simulation device of double hub is set on the testing platform body. One hub is installed location / movement sensor that can test the angular velocity and torque moment of the main driving wheel of the electric bicycle, and sends to control cabinet. Brace driving device is set in the testing platform body to simulate the stepping action to drive the bicycle to do circular motion. The brace driving device has toque moment / speed sensor to test the rotating speed and the toque moment to send to control cabinet. The invention could test the ratio of electromotor driving force to human force.

Description

technical field [0001] The invention belongs to the technical field of testing, in particular to testing equipment for electric bicycles, and more specifically to testing equipment for testing the driving force ratio of electric bicycles. Background technique [0002] Electric bicycles are non-motor vehicles that use batteries as energy sources to provide power assistance. In recent years, many cities have eliminated motorcycles and mopeds powered by fuel engines. Electric bicycles have become the new darling of urban transportation because of their lightness, labor-saving, green and environmental protection. many. Consumers always want electric bicycles to be as labor-saving as possible and as fast as possible, but from the perspective of traffic safety, this is obviously not the case. Since the electric bicycle itself is a light non-motor vehicle, its frame structure and braking device are all designed according to low speed and low load. Blindly pursuing high speed and ...
