Embodiment Construction

[0023] An embodiment of the present invention will be described below with reference to the drawings.

[0024] See attached picture. The equipment of this embodiment includes a test bench body 1, a control cabinet 2 and a host computer 3. The test bench body 1 and the control cabinet 2 are electrically connected with data lines at the same time, and the host computer 3 and the control cabinet 2 are connected. An electric bicycle 4, which is a test object, is placed on the test bench body 1, and the present invention tests the electric bicycle 4. The test bench body 1 is equipped with a clamping device 11 to fix the front wheel of the electric bicycle 4; there is also a pneumatic loading device 12 on the test bench body, which can simulate the load of the human body; the front wheel hub 13 and the rear wheel hub 14 constitute a road condition simulation device, A magnetic powder brake is provided on the front hub 13 to provide damping to the electric bicycle, and a photoelectric en...

Abstract

The invention relates to an electric bicycle driving force ratio detecting method that adopts brace driving device to simulate the stepping action to drive the bicycle to do circular motion. When the motor is shut down, the main driving wheel of the bicycle would be driven by the brace driving device to test the rotating speed and torque moment of the brace driving device, and the angular velocity and torque moment of the main driving wheel of bicycle. The consumption power would be calculated. Starting the electromotor, the main driving wheel would be driven to rotate by brace driving device and electromotor, testing the rotating speed and torque moment of brace driving device and the angular velocity and torque moment of the main driving wheel to calculate the driving force ratio of the electromotor bicycle. The invention would test different speed points and comparing the gained force ratio to the preset standard.

Description

Technical field [0001] The present invention belongs to the field of detection technology, especially the detection of electric bicycles, and more specifically, relates to a detection method for detecting the driving force ratio of electric bicycles. Background technique [0002] Electric bicycles are non-motorized vehicles that use batteries as energy sources and provide auxiliary power. In recent years, many cities have eliminated motorcycles and scooters powered by fuel engines. Electric bicycles have become the new favorite of urban mobility due to their light weight, labor-saving, and green environmental protection. The number of electric bicycles is increasing, and the manufacturers are also increasing. many. Consumers always hope that electric bicycles will save effort and be as fast as possible, but from the perspective of traffic safety, this is obviously not the case. Since the electric bicycle itself is a portable non-motor vehicle, its frame structure and braking devi...
