Embodiment Construction

[0031] Figure 1 ~ Figure 3 A preferred embodiment of the hub motor with torque sensing function of the present invention is shown, which includes a hub 1, a motor core and a drive hub 2, wherein the motor core is arranged inside the hub, and the drive hub 2 and the hub 1 coaxial fixed.

[0032] During practical application, the wheel hub 1 is installed on the rear wheel of the bicycle, which is rotatably connected to the bicycle frame, and the flywheel of the bicycle is coaxially fixed on the drive shaft sleeve 2 . Hub 1 is made of figure 1 The hub shell 1a and the hub right end cover 1b are locked and fixed together by six screws. In the electric mode, the motor core is energized to drive the wheel hub 1 to rotate, thereby driving the vehicle forward; in the human riding mode, the rider steps on the crank to drive the crankset to rotate through the chain, and the crankset drives the hub 1 through the drive bushing 2 Rotate, and then drive the vehicle to move forward.

Abstract

The invention discloses a hub motor with a torque sensing function. The hub motor comprises a hub, a motor core contained in the hub and a driving shaft sleeve fixed coaxially with the hub to be used for mounting a flywheel. The driving shaft sleeve comprises an outer sleeve body, an inner sleeve body and a plurality of connecting bars, wherein the outer sleeve body and the inner sleeve body are arranged coaxially, and the multiple connecting bars are connected between the outer sleeve body and the inner sleeve body and distributed at intervals in the circumferential direction. The outer sleeve body and the hub are fastened. A flywheel connecting structure used for being connected with the flywheel in a fastened mode is arranged on the inner sleeve body. Torque induction magnetic steel is fixedly arranged on the inner sleeve body. A signal output plate is fixedly arranged on the outer sleeve body. A Hall element corresponding to the torque induction magnetic steel is arranged on the signal output plate.

Description

technical field [0001] The invention relates to the field of electric bicycles, in particular to an electric bicycle and a hub motor thereof. Background technique [0002] Because of its light, labor-saving and pollution-free characteristics, electric bicycles are being increasingly used in countries all over the world. Traditional electric bicycles use handlebars to adjust the speed, and there are also so-called smart electric bicycles that use speed sensing devices to control the output power of the motor. Very laborious. Electric bicycles using torque sensing devices are just the opposite. When riding on flat ground, the output power of the motor is very small, which can make people feel easy to ride and save power, but it can output a larger current when going uphill. It saves effort to climb hills, and it is an electric bicycle that truly allows people to experience the natural integration of man and machine. [0003] The torque sensing device of existing electric bi...
