Embodiment Construction

[0028] refer to figure 1 and 5 , the present invention provides a center shaft torque sensing system for an electric bicycle with a central motor, which includes a center shaft 1, a strain sleeve 8, a sprocket bracket 10, a torque sensor 7 and a bottom bracket, and one end of the strain sleeve 8 passes through a bearing 2. It is fixed on the bottom bracket and connected with the sprocket bracket 10. The other end is set on the center shaft 1 and is fixedly connected with the center shaft. The inner surface of the strain sleeve fits the outer surface of the center shaft. The sleeve and the center shaft only There will be a relative micro-rotation without shaking up and down and left and right. When the foot pedals, no matter the left foot or the right foot, the pedaling force is transmitted to the strain sleeve 8 through the connection between the central axis and the sleeve, and the other end of the sleeve transmits the pedaling force through the chain wheel bracket 10 Get o...

Abstract

The invention provides a middle axle moment sensing system of an electric bicycle with a built-in motor. The middle axle moment sensing system comprises a middle axle, the built-in motor and a controller, and further comprises a torque sensor and a strain sleeve, wherein the controller is connected with the torque sensor and the built-in motor respectively; the motor comprises a main shell, a coil stator, a rotor, a motor output gear shaft, a planet speed reducing mechanism and a double-ratchet-wheel clutch; one end of the strain sleeve is connected with the double-ratchet-wheel clutch and the other end of the strain sleeve is arranged on the middle axle in a sleeving manner and is fixedly connected with the middle axle; the torque sensor is mounted on the sleeve; the motor output gear shaft is arranged on the middle axle in a sleeving manner and is connected with the motor rotor to form a whole body; the coil stator is fixed on the main shell; the rotor covers the outer side of the coil stator and is fixedly connected with the motor output gear shaft; the planet speed reducing mechanism is arranged in the main shell; and the gear shaft is engaged with the planet speed reducing mechanism by a gear. A motor driving system provided by the invention can be used for providing corresponding assistance according to the specific requirements for riding people.

Description

technical field [0001] The invention relates to a sensor system for center shaft torque, in particular to a center shaft torque sensor system for an electric bicycle with a central motor. Background technique [0002] At present, there is a center shaft torque sensing system for electric bicycles, which includes a motor and a controller, the controller is arranged outside the motor, and the controller controls the motor to output constant power to provide assistance for human pedaling. This motor drive system cannot provide corresponding assistance with the specific requirements of riders. [0003] In summary, people are in urgent need of a central axis torque sensing system for mid-motor electric bicycles. The torque sensor is sent to the controller through a signal transmitter, and what the torque sensor reflects is the real pedaling situation; at the same time, the motor drive system Provide corresponding assistance according to the specific requirements of riders. Con...
