Problems solved by technology

The motor of a traditional electric power-assisted bicycle is arranged on the hub. When the motor is running, it will generate magnetic force line cutting resistance. In order to overcome this part of resistance, the motor increases power consumption
In addition, in order to prolong the endurance performance of the electric motor, manufacturers desperately increase the power of the electric motor and increase the voltage and capacity of the battery, which makes the weight of the vehicle itself very heavy.

Embodiment Construction

[0015] Now elaborate the present invention in conjunction with accompanying drawing:

[0016] The hybrid bicycle of this embodiment includes a central shaft 1 and a central chain disc 2, on which the central shaft 1 is fitted with a revolving sleeve 3 that can rotate around the central shaft 1, and the central chain disc 2 is fixedly sleeved on the revolving sleeve 3 On one end of the central shaft 1, a ratchet star frame 4 is set, and a plurality of star teeth 5 are arranged on the circumference of the ratchet star frame 4. The revolution sleeve 3 extends into the ratchet star frame 4, and its corresponding position is formed with star teeth. The tooth 6 that 5 cooperates, the ratchet ring 7 that cooperates with star tooth 5 is sleeved on the outer circumference of ratchet star frame 4, and the dog ring 7 is fixed. A central axis ratchet mechanism 8 is arranged between the ratchet star frame 4 and the central axis 1. The central axis ratchet mechanism 8 is an internal tooth e...

Abstract

The invention discloses a hybrid bicycle comprising a central axis and centrally-arranged chain disk, wherein the central axis is sleeved with a revolving sleeve which can rotate around the central axis; the centrally-arranged chain disk is fixedly sleeved on the revolving sleeve; a first one-way clutch is arranged between the revolving sleeve and the central axis; and a second one-way clutch is arranged between the revolving sleeve and an electromotor with treading moment sensing function. The hybrid bicycle has the following advantages that the resistance for riding the bicycle driven by the electromotor is smaller, and the electrical energy is saved as much as possible, since no magnetic cutting line resistance exists when a hub electromotor runs. A driving way that a person and the electromotor act simultaneously can be realized; and under the control of a treading moment sensing device, a speed changing mechanism of the electromotor is controlled to change when the changing of treading force is detected, thereby realizing that the bicycle is driven to run forwards by combining physical strength and mechanical strength into one.

Description

Technical field: [0001] The invention relates to a hybrid bicycle. Background technique: [0002] The definition given by the state of electric power-assisted bicycles is a bicycle driven by the human body's physical strength and supplemented by electric motors. However, the electric power-assisted bicycles currently on the market have an abnormal phenomenon of human-machine separation drive. That is, when the electric motor is running, because its rotating speed is higher than the pedaling speed of the human body, when the electric motor is driven, people cannot help it at all. Due to the above reasons, the traditional driving method of this kind of electric power-assisted bicycle can only be driven by the motor alone, or can only be pedaled and ridden by manpower, which does not reflect the power-assisted function of the electric power-assisted bicycle at all, and violates the national definition of it. . The electric motor of a traditional electric power-assisted bicycl...
